comprising at least one reducing agent comprising a mercapto
functional group and at least one alkalizing agent, an individually
packaged malodor suppressant system, and, optionally, an
individually packaged fixing composition comprising an oxidizing

permanent deformation of hair comprising providing a permanent
shaping composition by mixing at least one reducing agent
comprising a mercapto functional group, at least one alkalizing
agent and a malodor suppressant system, applying the permanent
shaping composition to the hair, allowing the permanent shaping
composition to act on the hair, rinsing the hair with water,
applying to the hair a fixing composition comprising an oxidizing
agent for performing an oxidative post-treatment of the hair, and
rinsing the hair with water. The present invention further relates
to a use of a malodor suppressant system in a composition for the
treatment of hair, especially in a permanent shaping composition
for the permanent deformation of hair.
BACKGROUND OF THE INVENTION
[0002] The classic technique for permanent hair shaping, i.e.,
permanent waving and straightening of hair, is familiarly on two
treatment steps: In the first step, the cystine-disulfide bridges
of the keratin of the hair are opened by the action of a
composition that comprises a reducing ingredient (permanent shaping
composition). The hair is then put into the desires shape. In a
second step, cystine-disulfide bonds are closed again using a
fixative, that is, a composition comprising an oxidizing
ingredient.
[0003] As classic reducing agents, compounds comprising
mercapto-functional groups are used, for example thioglycolic acid,
ammonium or monoethanolamine salts of thioglycolic acid,
2-mercaptopropionic acid (thiolactic acid), 3-mercaptopropionic
acid, cysteine, and derivatives of these compounds, cysteamine,
mercaptocarboxylic acid esters, and
N-alkyl-2-mercaptoacetamides.
[0004] The first step, i.e., the cystine-disulfide opening
reaction, is typically carried out at a pH of 7.5 to 9 in the
presence of an alkalizing agent. The alkaline-adjusted permanent
shaping compositions based on mercapto-functionalized reducing
agents, however cause unpleasant odor. The unpleasant odor of the
reducing agents requires intensive perfuming of the products.
[0005] Despite the fact that commercial permanent hair deformation
products have been available for many years, still no products
exist which effectively reduce or even completely avoid the malodor
during and after the hair shaping process, and simultaneously
provide an effective permanent hair shaping effect.
[0006] By using thiolactic acid, it is possible to slightly reduce
the malodor. In comparison to the widely used thioglycolic acid,
the permanent deformation effectiveness of thiolactic acid is
however considerably weaker.
[0007] It is therefore a main objective of the present invention to
provide a composition and a method for permanent shaping hair which
significantly improves the odor during and after the shaping
process of the hair, provides an effective permanent hair shaping
performance, and which enhances the customer's acceptance of
permanent hair shaping products.
[0008] A further objective of the present invention is to provide a
permanent shaping composition and method that delivers unique
elasticity and strength of the shaped hair from the tip to the
root, an improved uniformity of the shaped hair with less
disordered appearance.
[0009] A further objective of the present invention is to provide a
composition and a method for permanent shaping hair which has
superior hair care effects especially with regard to improved soft
feel of wet and dry hair, improved elasticity of hair and durable
waving of the hair.
[0010] Another objective of the present invention is to provide a
composition and a method for permanent shaping hair which causes
less hair damage than compositions of the prior art.
[0011] A further objective of the present invention is to provide a
composition and a method for permanent shaping hair which
penetrates well into the hair but less into the skin than
compositions of the prior art.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE INVENTION
[0034] As used herein the term "hair" may be "living", i.e., on a
living body, or may be "non-living", i.e., in a wig, hairpiece or
other aggregation of non-living keratinous fibers. Mammalian,
preferably human hair is preferred. However wool, fur and other
keratin containing fibers are suitable substrates for the
compositions according to the present invention.
[0035] As used herein, the term "permanent shaping composition"
relates to compositions used in the first step of the permanent
deformation of hair, i.e., for the cystine-disulfide opening
reaction. The permanent shaping composition is referred hereinafter
as "the composition", unless otherwise specified. Permanent shaping
compositions according to the invention may be used for both,
permanent waving (i.e. curling of human hair) and straightening,
(i.e. smoothing of human hair).
[0036] All percentages are by weight of the permanent shaping
composition, i.e. of the ready-to-use composition which is the
composition to be applied on hair, unless otherwise specified. When
a ready-to-use composition is prepared by mixing two or more
components comprising ingredients to be mixed for the desired
effect, the amount of these ingredients is generally provided based
on the weight of the component comprising such an ingredient, in
case of the present text, e.g., the malodor system (c). Also ratios
are weight ratios unless specifically stated otherwise.
[0037] The term "malodor suppressant system" means a mixture of two
or more malodor suppressants.
[0038] The first aspect of the present invention is a permanent
shaping composition for the permanent deformation of hair
comprising, in a cosmetically acceptable carrier, [0039] (a) at
least one reducing agent comprising a mercapto functional group,
[0040] (b) at least one alkalizing agent, and [0041] (c) a malodor
suppressant system comprising at least a first malodor suppressant,
wherein the first malodor suppressant has a molecular weight of
from 100 to 400 g/mol, and wherein the malodor suppressant system
has a distribution coefficient log P (octanol/water) of 2 or
more.
Cosmetically Acceptable Carrier
[0042] The composition comprises a cosmetically acceptable carrier
or solvent. The solvent may be selected from water, or a mixture of
water and at least one organic solvent to dissolve the compounds
that would not typically be sufficiently soluble in water.
[0043] Suitable organic solvents include, but are not limited to:
C1 to C4 lower alkanols (such as ethanol, propanol, isopropanol);
aromatic alcohols (such as benzyl alcohol and phenoxyethanol);

dipropyleneglycol, polyglycerol); propylene carbonate; and mixtures
thereof.
[0044] The solvent may be selected from the group consisting of
water, ethanol, propanol, isopropanol, glycerol, 1,2-propylene
glycol, hexylene glycol, ethoxy diglycol, and mixtures thereof.
[0045] The composition may comprise water as a main ingredient,
particularly in a total amount ranging from at least 50%,
alternatively from at least 60%, alternatively from at least 70%,
based on the total weight of the composition. Typically, when
present, the composition comprises a total amount of organic
solvents ranging from 1% to 30%, based on the total weight of the
composition.
(a) Reducing Agent
[0046] The composition comprises at least one reducing agent. The
reducing agent comprises a mercapto-functional group.
[0047] According to the present invention, generally all reducing
agents known in the art which are suitable for use in the permanent
deformation of hair can be used.
[0048] Suitable reducing agents are for example thioglycolic acid
and thiolactic acid as well as the salts thereof, in particular the
ammonium and ethanolamine salts. Further useful thio compounds are
in particular cysteine or the hydrochloride thereof, homocysteine,
cysteamine, N-acetyl cysteine, thioglycerol, ethanediol
monothioglycolate, 1,2-propyleneglycol monothioglycolate,
1,3-propanediol monothioglycolate or the isomer mixture resulting
therefrom, 1,3-butanediol and 1,4-butanediol monothioglycolate and
the isomer mixtures therefrom, polyethylene glycol
monothioglycolates, such as di-, tri- and tetraethyleneglycol
monothioglycolates, glycerol monothiolactate, mercapto carboxylic
acids and esters thereof, N-alkyl-2-mercaptoacetamides, as well as
combinations of two or more thereof. The use of inorganic reducing
sulfur compounds such as sodium hydrogen sulfite is basically also
possible. Preferably, the reducing agent is selected from the group
consisting of cycteine, thioglycolic acid, thiolactic acid, and
salts thereof.
[0049] The permanent shaping compositions according to the present
invention comprise at least one reducing compound at a
concentration of at least 0.1 wt.-%, preferably at least 0.5 wt.-%,
more preferably at least 1 wt.-%, based on the total weight of the
composition. The total reduction agent content in the compositions
according to the invention customarily amounts from 0.1 to 35
wt.-%, preferably from 0.5 to 20 wt.-%, more preferably 1 to 15
wt.-%, based on the total weight of the composition.
(b) Alkalizing Agent
[0050] The composition comprises at least one alkalizing agent.
Alkalizing agents preferred within the scope of the invention are
for example ammonia, ammonium carbamate, ammonia,
ammonium(bi)carbonate, monoethanolamine, diethanolamine,
triethanolamine, 2-amino-2-methyl-1-propanol,
2-amino-2-methyl-1,3-propanediol, 2-amino-2-ethyl-1, 3-propanediol,
2-amino-1-butanole, tris(hydroxylmethyl)-aminomethane,
tris-(2-hydroxypropyl)-amine, lysine, 2,2-iminobisethanol,
iminourea (guanidine carbonate), tetrahydro-1,4-oxazine,

triisopropanolamine, glucamine, sodium hydroxide, potassium
hydroxide, lithium hydroxide, magnesium hydroxide, other
water-soluble physiologically tolerable salts of organic and
inorganic bases, and combinations of two or more thereof.
[0051] By varying the pH value, a composition can be made available
that is universally suitable for every hair structure, optionally
with the additional application of heat. The composition brings
about an elastic, durable and uniform waving from the root of the
hair to the ends, without eliciting allergic or sensitizing
reactions. It is desirable to adjust the pH value to between about
5.5 and 12, preferably about 6.5 and 10.5, most preferably about
7.5 to 9.5. Thus, the quantity of the alkalizing agent is dependent
on the reducing agent and the desired pH value of the
composition.
[0052] The permanent shaping composition preferably comprises 0.1
to 10 wt.-%, more preferably 0.2 to 5 wt.-% of the alkalizing
agent, based on the total weight of the composition.
(c) Malodor Suppressant System
[0053] The composition comprises a malodor suppressant system. The
malodor suppressant system comprises at least a first malodor
suppressant. The first malodor suppressant has a molecular weight
of from 100 to 400 g/mol. The malodor suppressant system has a
distribution coefficient log P (octanol/water) of 2 or more.
[0054] The malodor suppressant system may comprise only one first
malodor suppressant. Such systems are one-component malodor
suppressant systems ("one-component system") which do not comprise
any further malodor suppressants having a log P (octanol/water) of
2 or more and a density of 1.1 g/mL or less, preferably no further
suppressants selected from the group of compounds described below
and named "list of malodor suppressants".
[0055] Preferably, the malodor suppressant system comprises at
least a first malodor suppressant and at least a second malodor
suppressant, i.e., a two-component malodor suppressant system
("two-component system"). Optionally, the malodor suppressant
system may comprise one or more further malodor suppressants. The
first and the second malodor suppressants are different. Each of
the first and second malodor suppressants have a molecular weight
of from 100 to 400 g/mol. The malodor suppressant system has a
distribution coefficient log P (octanol/water) of 2 or more.
[0056] Unless otherwise indicated, the following description
relating to the first malodor suppressant defines both, the first
malodor suppressant in one-component systems and in two-component
systems.
[0057] In the fields of organic and medicinal chemistry, a
distribution (P) coefficient is the ratio of concentrations of a
compound in the two phases of a mixture of two immiscible solvents
at equilibrium. Hence these coefficients are a measure of
differential solubility of the compound between these two solvents.
One of the solvents chosen is water while the second is octanol.
Hence the partition coefficient is a measure of how hydrophilic
("water loving") or hydrophobic ("water fearing") a chemical
substance is. The partition coefficient is the ratio of
concentrations of un-ionized compound between the two solutions.
The logarithm of the ratio of the concentrations of the un-ionized
solute in the solvents is called log P:
log P oct / wat = log ( [ solute ] octanol [ solute ] water un -
ionized ) . ##EQU00001##
[0058] The log P (octanol/water) is referred hereinafter as "log
P", unless otherwise specified.
[0059] It can be preferred that the malodor suppressants comprise
at least one functional group selected from the group consisting of
keto groups, aldehyde groups, ether groups, ester groups and
hydroxyl groups. The first and the second malodor suppressants can
comprise or two or more of such groups, either of the same type or
of one or more different types.
[0060] The first malodor suppressant has a log P (octanol/water) of
at least 2, preferably of at least 3. Preferably, the first malodor
suppressant has a log P (octanol/water) of less than 9. More
preferably, the first malodor suppressant has a log P
(octanol/water) in the range of from 2 to less than 9, for example
in the range of from 3 to less than 9.
[0061] The first second malodor suppressant has a log P
(octanol/water) of at least 2, preferably of at least 3.
Preferably, the second malodor suppressant has a log P
(octanol/water) of less than 9. More preferably, the second malodor
suppressant has a log P (octanol/water) in the range of from 2 to
less than 9, most preferably in the range of from 3 to less than
9.
[0062] While generally all types and combinations of malodor
suppressants according to the teaching of the present invention
provide for a reduced malodor of the compositions, it has proven to
be advantageous in many cases if at least the first malodor
suppressant has a log P (octanol/water) of less than 9. In a
further embodiment of the invention at least the first and the
second malodor suppressant have a log P (octanol/water) of less
than 9.
[0063] The first and second malodor suppressants may be a liquid at
23.degree. C. and 1013 mbar. Preferably, the malodor system (c) is
a liquid at 23.degree. C. and 1013 mbar. It may also be preferred
that the first and second malodor suppressants form a solution upon
mixing.
[0064] It may also be preferred that at least two malodor
suppressants in a combination of first and second malodor
suppressants have a log P (octanol/water) of 3 or more and a
molecular weight in the range of from 100 to 400 g/mol.
[0065] It is also possible that the malodor suppressant system
comprises a first malodor suppressant being a compound having a
distribution coefficient log P (octanol/water) of 2 or more and a
molecular weight of between 100 and 400 g/mol and at least a second
malodor suppressant being a compound having a distribution
coefficient log P (octanol/water) of 3 or more and a molecular
weight of between 100 and 400 g/mol, the first malodor suppressant
and the second malodor suppressant being different compounds and at
least one of the first and second malodor suppressants being liquid
at 23.degree. C. and 1013 mbar and the first and second malodor
suppressant forming a solution upon mixing.
[0066] It has further been found that a permanent shaping
composition according to the invention has especially good malodor
suppression properties, if the density of the malodor suppressant
system (c) present in the permanent shaping composition divided by
the density of the permanent shaping composition without the
malodor suppressant system (c) is 1.1 or less.
[0067] The density ratio mentioned above is thus measured for the
malodor suppressant system (c), and is advantageously about 1.1 or
less, and should advantageously be higher than about 0.85.
Preferably, the density ratio ranges from about 1.09 to about 0.87,
or from about 1.05 to about 0.88, or from about 1.01 to about 0.9,
or from about 1.0 to about 0.92.
[0068] The density of the malodor suppressant system (c) is
preferably about 1.1 g/mL or less, and should advantageously be
higher than about 0.85 g/mL. Preferably, the density of the malodor
suppressant system (c) ranges from about 1.09 to about 0.87 g/mL,
or from about 1.05 to about 0.88 g/mL, or from about 1.01 to about
0.9 g/mL, or from about 1.0 to about 0.92 g/mL.
[0069] The density of at least one of the malodor suppressants is
preferably about 1.1 g/mL or less, and should advantageously be
higher than about 0.85 g/mL. Preferably, the density of at least
one of the malodor suppressants ranges from about 1.09 to about
0.87 g/mL, or from about 1.05 to about 0.88 g/mL, or from about
1.01 to about 0.9 g/mL, or from about 1.0 to about 0.92 g/mL. More
preferably, the density of each of the malodor suppressants is
preferably about 1.1 g/mL or less, and should advantageously be
higher than about 0.85 g/mL. Preferably, the density of each of the
malodor suppressants ranges from about 1.09 to about 0.87 g/mL, or
from about 1.05 to about 0.88 g/mL, or from about 1.01 to about 0.9
g/mL, or from about 1.0 to about 0.92 g/mL.
[0070] All densities relate to a temperature of 23.degree. C. and a
pressure of 1.013 bar. Density measurements are typically performed
via determining the weight and the volume of the compound to be
measured, or according to any other processes known to the skilled
person.
[0071] Generally, it has proven to be successful for the
one-component system if the first malodor suppressant is selected
from the group consisting of Galaxolide, Operanide, Okoumal,
habanolide and isopropylmyrstate.

system or a two-component malodor suppressant system. The malodor
suppressant of the one-component malodor suppressant system is
preferably selected from the group consisting of Galaxolide,
Operanide, Okoumal, habanolide and isopropylmyrstate. The malodor
suppressants of the two-component malodor suppressant system are
preferably selected from the group of compounds described above and
named "list of malodor suppressants".
[0150] The kit may also comprise a further component C. Component C
is a composition for oxidatively post-treating (fixing) the hair
comprising an oxidizing agent.
[0151] Any known oxidizing agents that have been used before in
fixing compositions can be used for the fixation. Examples of such
oxidizing agents are potassium bromate, sodium bromate, sodium
perborate, dehydroascorbic acid, urea peroxide, hydrogen peroxide,
and inorganic peroxygen materials capable of yielding hydrogen
peroxide in an aqueous solution. Such materials are for example
inorganic alkali metal peroxides (such as sodium periodate and
sodium peroxide); organic peroxides (such as urea peroxide and
melamine peroxide); inorganic perhydrate salt bleaching compounds
(such as the alkali metal salts of perborates, percarbonates,
perphosphates, persilicates, persulphates and the like); and
mixtures thereof. Inorganic perhydrate salts may be incorporated
for example as monohydrates, or tetrahydrates. Alkyl/aryl peroxides
and/or peroxidases may also be used. Mixtures of two or more such
oxidizing agents can be used if desired. The oxidizing agents may
be provided in aqueous solution or as a powder which is dissolved
prior to use. Hydrogen peroxide is preferred.
[0152] The concentration of the oxidizing agent varies, depending
on the application time and the application temperature. Generally,
oxidizing agents are used in a concentration of from about 0.5 to
12 wt.-%, preferably 1 to 3 wt.-%, based on the total weight of the
fixing composition.
[0153] The fixing composition can comprise other materials, for
example, weak acids or peroxide stabilizers. The fixing composition
may also include other substances, such as wetting agents,
hair-care substances such as cationic polymers, weak acids, buffer
substances or peroxide stabilizers, and may be in the form of an
aqueous solution, an emulsion, or a thickened water-based form, in
particular a cream, gel or paste. These typical additives may be
contained in the fixing composition in a quantity of from 0.1 to 10
wt.-%, based on the total weight of the fixing composition.
[0154] The fixing composition can be present in the form of an
aqueous solution or an emulsion, as well as in a thickened form on
an aqueous basis, particularly as a cream, gel, or paste. It is
also possible to fill these compositions into aerosol cans under
pressure and to release them as aerosol foam. Preferably, the
fixing composition is an aqueous solution or emulsion.
[0155] The consumer mixes the components A and B together
immediately before use and applies it onto the hair. They may be
mixed from 5 sec to 3 min, alternatively from 15 sec to 2 min,
alternatively for 30 sec to 1 min prior application to the
hair.
[0156] The present invention may be provided in a variety of
packaging devices and/or dispensing devices. These dispensing
devices can come in the form of separate devices which may be used
independently or in combination with one another. Typically, the
compositions are contained within separate single or
multi-compartment containers so that the compositions can be stored
separately from one another before use. For use, the compositions
are dispensed from the respective device and applied to the
consumer's hair by an application means.
[0157] A preferred packaging device involves storing the
composition A in a first container such as a bottle, tube, aerosol,
or a sachet, separately storing the malodour suppressant system in
an additional compartment within the first container or more
preferably in a separate container which may be identical such as a
dual sachet or aerosol systems, or different such as a bottle and
tube system. Any combination may be used and is typically
contingent on the type of composition being stored, e.g., based on
its viscosity. The compositions A and B may be mixed by any means,
including by using a mixing bowl and/or a mixing tool, by adding
one component into the container of the other component followed by
mixing, by perforating or displacing a seal located between the
separate compartments of the components within a single container
or sachet followed by mixing. As an alternative, the compositions A
and B can be mixed directly in the hair or on the head of a
consumer.
[0158] The devices described herein above can also be used in
combination with a product delivery and or application tool to aid
application of the product onto the hair, including using a nozzle
attached to one of the containers, using a separate applicator
device such as a comb or brush, using a comb attached to or instead
of the dispensing nozzle whereby the product is dispensed through
hollow tines and dispensing apertures located in the comb tines.
The application devices may also include devices which assist in
achieving particular effects such as highlighting such as
highlighting combs, brushes and tools, foils and highlighting caps.
Highlighting devices comprising a hinged device into which an
amount of composition is placed and then used to apply the
composition to pre-determined/selected hair strands may also be
used. Additional device technology can be used to assist in the
penetration of the product into the hair. Examples of such
technology include heating devices, ultraviolet light devices and
ultrasound devices.
[0159] The permanent shaping and fixing compositions, may be
manufactured by conventional processes known in the art for
manufacturing permanent shaping and fixing products, e.g., by
admixing the ingredients of each composition in suitable vessels,
followed by packaging in appropriate individual containers.
[0160] The third aspect of the present invention is a method for
the permanent deformation of hair comprising the following steps:
[0161] i. providing a permanent shaping composition by mixing
[0162] (a) at least one reducing agent comprising a mercapto
functional group, [0163] (b) at least one alkalizing agent, and
[0164] (c) a malodor suppressant system comprising at least a first
malodor suppressant, wherein the first malodor suppressant has a
molecular weight of from 100 to 400 g/mol, and wherein the malodor
suppressant system has a distribution coefficient log P
(octanol/water) of 2 or more; [0165] ii. applying the permanent
shaping composition to the hair before or after putting the hair in
a desired shape; [0166] iii. allowing the permanent shaping
composition to act on the hair for a predetermined acting time
sufficient for the permanent shaping of the hair; [0167] iv.
rinsing the hair with water; [0168] v. applying to the hair a
fixing composition comprising an oxidizing agent for performing an
oxidative post-treatment of the hair; and [0169] vi. rinsing the
hair with water.
[0170] In the method for the permanent deformation of hair
according to the present invention, the carrier, the reducing agent
(a), the alkalizing agent (b) and the malodor suppressant system
(c) are in accordance with the carrier, reducing agent (a),
alkalizing agent (b) and malodor suppressant system (c) described
with regard to the first aspect of the invention. In particular,
the malodor suppressant system may be a one-component malodor
suppressant system or a two-component malodor suppressant system.
The malodor suppressant of the one-component malodor suppressant
system is preferably selected from the group consisting of
Galaxolide, Operanide, Okoumal, habanolide and isopropylmyrstate.
The malodor suppressants of the two-component malodor suppressant
system are preferably selected from the group of compounds
described above and named "list of malodor suppressants". Further,
the fixing composition is in accordance with the fixing composition
described with regard to the second aspect of the invention.
[0171] The method comprises as a first step the provision of a
permanent shaping composition. Said composition is provided by
mixing at least one reducing agent (a), at least one alkalizing
agent (b) and a malodor suppressant system (c).
[0172] The components (a) to (c) may be mixed at any time before
use. For example, the components (a) to (c) may be mixed before
being packaged, so that the customer may purchase the permanent
shaping composition already in mixed form. However, the components
are preferably mixed immediately before use. "Use" of the
composition according to the present invention means working the
permanent shaping composition into the hair "Immediately before
use" according to the present invention means no more than 5 min
before use. It is however preferred to add the hair serum no more
than 3 min before use, for example, no more than 2 min before use
or no more than 1 min before use. It is most preferred to add the
hair serum less than 1 min before use.
[0173] The components may be mixed by any means, including using a
mixing bowl and/or a mixing tool, adding one component into the
container of the other component followed by mixing, perforating or
displacing a seal located between the separate compartments of the
components within a single container or sachet followed by
mixing.
[0174] Subsequently, after mixing the components as described
above, the permanent shaping composition is applied to the
hair.
[0175] Either before or after applying the permanent shaping
composition, the hair is put into the desired shape, preferably as
follows: First the hair (which is washed and towel-dried) is
separated into multiple sections and then these sections are rolled
onto curlers. The curlers used for permanent waves have a diameter
of about 5 to 13 mm, while the curlers used for straightening must
have a diameter greater than 13 mm After the hair is rolled on
curlers, the curlers are thoroughly wetted down using the permanent
shaping composition. As an alternative, the hair may be thoroughly
wetted down using the permanent shaping composition before being
curled on the rollers, while the procedure of rolling the hair onto
curlers is the same.
[0176] The permanent shaping composition is then allowed to act on
the hair for a predetermined acting time sufficient for the
permanent shaping of the hair. The amount of time the permanent
shaping composition stays on the hair is from about 1 to about 30
min, preferably from about 5 to about 20 min. This time can be
shortened by adding heat via the use of a heat radiator or a hood
dryer. This time is dependent from the hair quality, the pH value,
the shaping effectiveness of the color-providing shaping agent, the
desired level of change as well as on the application
temperature.
[0177] The hair is then rinsed with water.
[0178] As a further step, the method comprises the application of a
fixing composition comprising an oxidizing agent for performing an
oxidative post-treatment of the hair. Depending on the hair
thickness and length, the amount of fixing composition, the
application time and the application temperature can vary.
Preferred application times are in the range of from 1 to 40 min,
for example 2 to 20 min, more preferably 5 to 10 min. Preferred
application temperatures are in the range of from 25 to 40.degree.
C.
[0179] After the oxidative post-treatment, the hair is rinsed with
water. The curlers may be removed from the hair at any time after
the oxidative post-treatment, preferably before the hair is rinsed
with water.
[0180] As a fourth aspect, the present invention relates to the use
of a malodor suppressant system comprising a first malodor
suppressant, a second malodor suppressant, and, optionally, one or
more further malodor suppressants, wherein the first malodor
suppressant is different from the second malodor suppressant,
wherein each of the first and second malodor suppressants have a
molecular weight of from 100 to 400 g/mol, and wherein the malodor
suppressant system has a distribution coefficient log P
(octanol/water) of 2 or more, in a composition for the treatment of
hair, especially in a permanent shaping composition for the
permanent deformation of hair.
[0181] The malodor suppressant system used according to this aspect
of the invention is in accordance with the malodor suppressant
system (c) described with regard to the first aspect of the
invention.
Examples
[0182] In order to determine the influence of the malodor
suppressant systems on different permanent shaping compositions,
test samples were provided and analyzed.

Test Procedure 1
[0187] After wetting the hair with water, it is wound up on
curlers. The permanent shaping premix are mixed with the malodor
suppressant system to form the permanent shaping composition
comprising the malodor suppressant system in an amount of 0.7
wt.-%. The permanent shaping composition is uniformly applied onto
the hair on the curlers. The permanent shaping composition is left
there for 10 min using an infrared drying hood and a temperature of
40.degree. C. The hair is then rinsed with lukewarm water. The
fixing composition is then uniformly applied to the hair and left
there for 8 min. Finally, the hair is rinsed with lukewarm water
and the curlers are removed.
[0188] The procedure is carried out for each of the above
identified malodor suppressant systems.
[0189] As a comparative example C2, the procedure is carried out
without addition of a malodor suppressant (C2). In this case, the
permanent shaping premix is uniformly applied onto the hair on the
curlers. The further procedure is carried out as described
above.
[0190] The treated hair has a well groomed look in wet and dry
condition, a good touch and fine wet combing properties. It
displays a good elasticity from the tips to the root. During the
treating time with the malodor suppressant systems D1 to D5 and S1
to S6, a reduced and more pleasant odor is noticed compared to
using malodor suppressant system C1 or no malodor suppressant
system (C2).
Test Procedure 2
[0191] A paneltest was performed with 5 panelists with trained
expertise in the classification of thiol malodour. The panelists
received a mixture of the permanent shaping premix and 0.7 wt.-% of
one malodor suppressant system, as described above (stirred by a
single operator for all tests). Immediately and 25 min after
mixing, the panelists were asked to rate the thiol malodor
according to a scale of 0 to 5 (0=no thiol smell, 5=harsh thiol
smell), the mixture being passed from panelist to panelist with an
additional stirring for each of the panelists.
