Description
FIELD OF THE INVENTION
[0001] The disclosure relates to cosmetic compositions, such as
shampoos, body cleansers, and face cleansers, for treating and/or
cleansing keratinous materials and to methods of cleansing
keratinous materials.
BACKGROUND
[0002] Consumers desire compositions for applying to and/or
cleansing keratinous materials, including hair and skin. Such
compositions require a certain viscosity or rheology to be
recognized as a specific product--e.g., a shampoo, a body cleanser,
or a face cleanser--and to be convenient for dispensing and using
and thus desirable to consumers. It is known practice to use
compositions that contain conventional thickeners, either natural
or synthetic, in order to give such compositions a certain
viscosity or rheology. Nonetheless, chemicals and raw materials
used in cleansing compositions, including conventional thickeners,
may lack sustainable sourcing and not comply with "green"
manufacturing processes, which in turn can lead to harmful effects
on the environment.
[0003] Consumers also desire cleansing compositions that adequately
cleanse the hair and/or skin, without leaving undesirable amounts
of coating and/or residue on the hair and/or skin. Coating and/or
residue left on the hair and/or skin is usually attributable to
conventional thickeners, including sclerotium gum.
[0004] It is also desirable for consumers to use cleansing
compositions that produce adequate foam in addition to also being
sulfate-free.
[0005] Due to the concerns regarding conventional thickeners and/or
sulfate-containing surfactants, manufacturers seek to formulate
compositions for applying to and/or cleansing keratinous materials
using ingredients and combinations of ingredients that can minimize
or prevent the above-described disadvantages. However, the choice
of ingredients or combinations of ingredients could pose
difficulties insofar as they cannot be detrimental to other
cosmetic attributes such as cosmetic feel, volume, bounce, hair
individualization, and suppleness; viscosity or rheology properties
of cleansing compositions; stability of the compositions, or result
in more disadvantages such as increased irritation of the scalp and
damage to the hair. It is therefore desirable to provide the
consumer with compositions that can care for and/or cleanse
keratinous materials, wherein the compositions have the desired
viscosity or rheology and cosmetic attributes, while being
comprised of raw materials that are of sustainable sourcing and
produced by green manufacturing processes. It is also desirable to
provide consumers with compositions that are sulfate-free.
[0006] The disclosed embodiments provide compositions for applying
to and/or cleansing keratinous materials.
[0007] It has now been surprisingly and unexpectedly discovered
that combining at least one carboxylate anionic surfactant, at
least one secondary surfactant other than the at least one
carboxylate anionic surfactant, at least one glyceryl ester, and a
cosmetically acceptable solvent, wherein the at least one
carboxylate anionic surfactant and the at least one glyceryl ester
are present in a weight ratio ranging from about 0.50 to about
1.00, results in compositions with the desired level of viscosity
or rheology, without using conventional thickeners (e.g., without
using synthetic associative thickeners and/or thickening polymers).
Such compositions also provide an acceptable level of cosmetic
attributes to the keratinous materials, such as cleaner feel to the
hair, with less coating and deposition. The compositions also
provide adequate foaming while being sulfate-free.

[0210] The viscosities of the compositions were measured using the
Ford Cup to capture a total of 90 g sample flowing through an
opening diameter of 6 mm at 25.degree. C. The viscosity of the
inventive compositions fell in the range of 50-70 seconds. The
inventive compositions did not contain conventional thickener(s).
The viscosity of the comparative formula fells in the range of
70-120 seconds.
[0211] A shampoo according to Example 1 was tested and compared to
the Reference Product (Example 4) on 10 volunteers by applying the
shampoo of Example 1 to hair on half of the volunteer's head and
Example 4 on the other half of the head, lathering, rinsing, and
then blow drying the hair. The composition of Example 1 produced a
foam that was more airy. The foam was also easier to rinse from the
hair. It also left the hair feeling cleaner (more squeaky clean),
better individualized, and less coated, compared to the Reference
Product, which contained polymer thickeners.
[0212] As used herein, the terms "comprising," "having," and
"including" are used in their open, non-limiting sense.
[0213] The terms "a," "an," and "the" are understood to encompass
the plural as well as the singular.
[0214] The expression "one or more" means "at least one" and thus
includes individual components as well as
mixtures/combinations.
[0215] Ranges can be expressed herein as from "about" one
particular value, and/or to "about" another particular value. When
such a range is expressed, examples include from the one particular
value and/or to the other particular value. Similarly, when values
are expressed as approximations, by use of the antecedent "about,"
it will be understood that the particular value forms another
aspect. It will be further understood that the endpoints of each of
the ranges are significant both in relation to the other endpoint,
and independently of the other endpoint.
[0216] All percentages, parts and ratios herein are based upon the
total weight of the compositions of the present disclosure, unless
otherwise indicated.
[0217] As used herein, all ranges provided are meant to include
every specific range within, and combination of sub ranges between,
the given ranges. Thus, a range from 1-5, includes specifically 1,
2, 3, 4 and 5, as well as sub ranges such as 2-5, 3-5, 2-3, 2-4,
1-4, etc.
[0218] The term "substantially free" or "essentially free" as used
herein means that there is less than about 2% by weight of a
specific material added to a composition, based on the total weight
of the compositions. The compositions of the disclosure may be free
of the component(s) or may be "substantially free" or "essentially
free" of the component(s) described for optional inclusion in said
compositions. Nonetheless, the compositions may include less than
about 1 wt. %, less than about 0.5 wt. %, less than about 0.1 wt.
%, or none of the specified material or components.
[0219] Unless otherwise expressly stated, it is in no way intended
that any method set forth herein be construed as requiring that its
steps be performed in a specific order. Accordingly, where a method
claim does not expressly recite an order to be followed by its
steps or it is not otherwise specifically stated in the claims or
descriptions that the steps are to be limited to a specific order,
it is no way intended that any particular order be inferred.
