[0028] The novel indanylidene compounds represent a surprising
selection from the indanylidene compounds known from EP-A 823 418.
They have a significantly higher photostability than the compounds
mentioned in EP-A 823 418 and higher compatibility with other UV
filters, such as, for example, isooctyl p-methoxycinnamate.
[0029] Preference is give to indanylidene compounds of the formula
##STR3##
[0030] More preference is given to indanylidene compounds of the
formula ##STR4##
[0031] Specifically, the following preferred indanylidene compounds
may be mentioned:
[0032]
2-(5,6-Dimethoxy-3,3-dimethyl-1-indanylidene)-4,4-dimethyl-3-oxo-p-
entanontrile,
2-(5-methoxy-3,3,4,8-tetramethyl-1-indanylidene)-4,4-dimethyl-3-oxo-penta-
nonitrile,
2-(3,3,5,6-tetramethyl-1-indanylidene)-4,4-dimethyl-3-oxo-penta-
nonitrile,
2-(3,3,6-trimethyl-1-indanylidene)-4,4-dimethyl-3-oxo-pentanoni-
trile,
2-(5,6-ethylenedioxo-3,3-dimethyl-1-indanylidene)-4,4-dimethyl-3-ox-
o-pentanonitrile,
2-(5-methoxy-3,3,6-trimethyl-1-indanylidene)-4,4-dimethyl-3-oxo-pentanoni-
trile,
2-[(5-methoxy-3,3-dimethyl-(2-methyl-3-(1,3,3,3-tetramethyl-1-(trim-
ethyl-silyloxy)-disiloxanyl)-propyl)-indanylidene)]-4,4-dimethyl-3-oxo-pen-
tanonitrile and
2(6-3,3-dimethyl-5-methoxy-1indamylidene)-4,4-dimethyl-3-oxo-pentanonitri-
le.
[0033] The indanylidene compounds according to the present
invention can be prepared by (knoevenagel) condensation of
compounds of the formula ##STR5## where [0034] R.sup.1 to R.sup.8
have the meanings given above, with compounds of the formula
##STR6## where [0035] R.sup.9 to R.sup.11 and X have the meanings
given above.
[0036] The indanones used here can be prepared by Friedel-Crafts
Reactions of (substituted) acrylic esters with (substituted)
aromatics or, in the case of hydroxyl substituents, by Fries
rearrangement of corresponding phenyl esters (F. -H. Marquardt,
Helv. Chim. Acta 159, 1476 (1965)).
[0037] The preparation of the indanylidene compounds according to
the present invention can, for example, be carried out as
follows.
[0038] The above-mentioned indanones are condensed with equimolar
amounts of pivaloylacetonitrile with the catalysis of ammonium
acetate according to the conditions of a Knoevenagel
condensation.
[0039] The preparation can be illustrated by the reaction scheme
below. ##STR7##
[0040] The indanylidene compounds according to the present
invention can be used as UV absorbers, e.g. in cosmetic
compositions, in particular for protecting against acute skin
damage (sunburn) and also chronic skin damage (premature skin
aging), particularly in sunscreen compositions, daily care products
and hair care products, but also for improving the photostability
of technical products, such as paints, surface coatings, plastics,
textiles, packaging materials and rubbers.
[0041] The indanylidene compounds according to the present
invention can be used individually or in a mixture in the
corresponding preparations; it is also possible to use them in
combination with UV absorbers of other classes of substance, and
also with the latter in any desired mixtures with one another. For

[0127] The list of UV filters given which can be used for the
purposes of the present invention is not of course intended to be
limiting.
[0128] The total amount of all (mono- and polysulfonated)
water-soluble UV filter substances in the finished cosmetic or
dermatological preparations, for example of
phenylene-bis-benzimidazyl-tetrasulfonic acid disodium salt or
salts thereof and/or the corresponding disulfonic acid or salts
thereof and/or 2-phenylbenzimidazole-5-sulfonic acid and salts
thereof and/or 2-hydroxy-4-methoxybenzophenone-5-sulfonic acid and
salts thereof and/or 4-(2-oxo-3-bomylidenemethyl)-benzenesulfonic
acid and salts thereof and/or
2-methyl-5-(2-oxo-3-bornylidene-methyl)-benzenesulfonic acid and
salts thereof and/or
benzene-1,4-di-(2-oxo-3-bornylidenemethyl)-10-sulfonic acid and
salts thereof, is advantageously chosen from the range from 0.1 to
10.0% by weight, preferably 0.6 to 6.0% by weight, based on the
total weight of the preparations, if the presence of these
substances is desired.
[0129] The total amount of oil-soluble UV filter substances in the
finished cosmetic or dermatological preparations, for example of
tris(2-ethylhexyl)
4,4',4''-(1,3,5-triazine-2,4,6-triyltriimino)-tris-benzoate and/or
4-tert-butyl-4'-methoxy-dibenzoylmethane and/or
4-methylbenzylidenecamphor and/or octyldimethyl-p-aminobenzoic acid
and/or Mexoryl.RTM.XL and/or Uvasorb.RTM.HEB and/or Tinosorb.RTM.S
and/or benzophenone-3 and/or Parsol.RTM.SLX and/or Neo
Heliopan.RTM.MA is advantageously chosen from the range from 0.1 to
10.0% by weight, preferably 0.5 to 6.0% by weight, based on the
total weight of the preparations, if the presence of these
substances is desired.
[0130] The total amount of 2-ethylhexyl p-methoxycinnamate and/or
isoamyl p-methoxycinnamate in the finished cosmetic or
dermatological preparations is advantageously chosen from the range
from 0.1 to 15.0% by weight, preferably 0.5 to 7.5% by weight,
based on the total weight of the preparations, if the presence of
these substances is desired.
[0131] The total amount of ethylhexyl 2-cyano-3,3-diphenylacrylate
in the finished cosmetic or dermatological preparations is, if the
presence of this substance is desired, advantageously chosen from
the range from 0.1 to 15.0%, preferably 0.5 to 10.0% by weight,
based on the total weight of the preparations.
[0132] The total amount of one or more salicylic acid derivatives
in the finished cosmetic or dermatological preparations is
advantageously chosen from the range from 0.1 to 15.0% by weight,
preferably 0.5 to 10.0% by weight, based on the total weight of the
preparations. If ethylhexyl salicylate is chosen, it is
advantageous to choose its total amount from the range from 0.1 to
5.0% by weight. If homomenthyl salicylate is chosen, it is
advantageous to choose its total amount from range from 0.1 to
10.0% by weight.
[0133] The indanylidene compounds according to the present
invention are also suitable to a particular degree for
photostabilizing UV absorbers with low UV photostability. The
photostabilization of the very photo-unstable compounds of the
dibenzoylmethane, e.g. tert-butyl-4'-methoxydibenzoyl-methane, is
particularly successful.
[0134] A further photostable UV filter combination is achieved
using 0.1 to 10% by weight, preferably 1 to 10% by weight, of
ethylhexyl p-methoxycinnamate or isoamyl p-methoxy cinnamate with
0.1 to 10% by weight, preferably 1 to 6% by weight, of the compound
of the formula I, preferably in the ratio 1:1.
[0135] The combinations of p-methoxycinnamic esters and
dibenzoylmethane derivatives and compounds of the formula I can be
formulated to be photostable by using, for example, 0.1 to 5% by
weight, preferably 1 to 3% by weight, of
4-tert-butyl-4'-methoxydibenzoyl-methane, 0.1 to 10% by weight,
preferably 1 to 7.5% by weight of ethylhexyl p-methoxycinnamate or
isoamyl p-methoxycinnamate and at least 0.2% by weight, preferably
1 to 6% by weight, of the compounds of the formula I, preferably in
the ratio 1 part of dibenzoylmethane derivative, 2 parts
p-methoxycinnamic ester and 2 parts of the indanylidene compounds
according to the invention.
[0136] In addition, it is advantageous to add one or more very
photostable UV absorbers to this three-way combination, such as,
for example, methylbenzyldenecamphor, 2-ethylhexyl
2-cyano-3,3'-diphenylacrylate, octyltriazone, Uvasorb.RTM.HEB,
Tinosorb.RTM.S, Tinosorb.RTM.M, ethylhexyl salicylate, homomenthyl
salicylate, and phenylenebisimidazolesulfonic acid or
phenylene-bis-benzimidazole-tetrasulfonic acid disodium salt,
Mexoryl.RTM.SX, Mexoryl.RTM.XL or Parsol.RTM.SLX.
[0137] In addition, in cosmetic preparations, a synergistic
increase in the sun protection factor is surprisingly achieved
using indanylidene derivatives of the formula I in combination with
other UV filters. Examples of a synergistic increase in the sun
protection factor are cosmetic emulsions which comprise both a
compound of the formula I and also ethylhexyl methoxycinnamate or
octocrylene, or a combination of a compound of the formula I with
ethylhexyl methoxycinnamate and 2-phenylbenzimidazolesulfonic acid,
or ethylhexyl methoxycinnamate and methylbenzylidenecamphor, or
ethylhexyl methoxycinnamate and
4-t-butyl-4'-methoxydibenzoylmethane, or Neo Heliopan.RTM.AP and
ethylhexyl methoxycinnamate, or a combination of a compound of the
formula I with octocrylene, methylbenzylidenecamphor and zinc
oxide. Combinations of a compound of the formula I with
dibenzoylmethanes, methylbenzylidenecamphor,
2-phenylbenzimidazolesulfonic acid, Neo Heliopan.RTM.AP,
Mexoryl.RTM.SX, Mexoryl.RTM.XL, Parsol.RTM.SLX, Tinosorb.RTM.S,
Tinosorb.RTM.M, Uvinul.RTM.T150, Uvasorb.RTM.HEB, and microfine
pigments, zinc oxide and titanium oxide, also have synergistic
increases in the sun protection factors. Such UV filter
combinations are listed by way of example, and are not to be
understood as being limited to the above-mentioned combinations.
Thus, it is possible to use combinations of all UV absorbers
already mentioned as particularly suitable on pages 8/9, and UV
filters approved in the subsequent publications with compounds of
the formula I or the above-mentioned combinations, individually or
in any desired mixtures. [0138] USA: Food and Drug Administration
(FDA). Publication in monograph for Sunscreen Drug Products for
Over-The-Counter Human Use. [0139] Europe: EC Directive 76/768 of
the Council for adapting the legal provisions of the member states
regarding cosmetic compositions to technical progress. Publications
in the Official Journal of European Communities. [0140] Japan:
Publication of the Cosmetics Directive of the Ministry of Health
and Welfare (MHW). [0141] Germany: Publication in the Verordnung
uber kosmetische Mittel [Directive concerning cosmetic
compositions] according to the Lebensmittel- und
Bedarfsgegenstande-Gesetz (LMBG) [Act relating to Foods and
Commodities]. [0142] Australia: Registration by Therapeutic Goods
Administration (TGA) and publication in the Australian Register of
Therapeutic Goods (ARTG).
[0143] These combinations usually achieve a synergistic increase in
the UV sun protector factor.
[0144] The combination of compounds of the formula I with UV-A
absorbers, particularly UV-A-II absorbers, gives broad protection
against UV-A radiation (320-400 nm). In particular, a combination
of compounds of the formula I with Neo Heliopan.RTM.AP (UV-AII
absorber) is to be mentioned for broad UV-A protection
performances. Further, UV-A filters which are used in combination
with compounds of the formula I alone or in combination of
compounds of the formula I and Neo Heliopan.RTM.AP are
Mexoryl.RTM.SX, Mexoryl.RTM.XL, Tinosorb.RTM.M, Tinosorb.RTM.S,
benzophenone-3, benzophenone-4, Neo Heliopan.RTM.357, Neo
Heliopan.RTM.MA.
[0145] For optimum broad-band protection against UV-A and UV-B
radiation, the above-mentioned combinations are to be combined with
all UV-B filters and mixtures of these filters (cf. list on pages
6-9). Preferably suitable are Neo Heliopan.RTM.AV, Neo
Heliopan.RTM.E1000, Neo Heliopan.RTM.Hydro, Neo Heliopan.RTM.MBC,
Neo Heliopan.RTM.303, Neo Heliopan.RTM.OS, Neo Heliopan.RTM.HMS,
Uvinul.RTM.T150, Uvasorb.RTM.HEB, ethylhexyl
dimethylaminobenzoate.
[0146] Combining compounds of the formula I with Neo
Heliopan.RTM.AP and a UV-B filter, e.g. ethylhexyl methoxycinnamate
or UV-B filter mixtures, and coated or uncoated finely disperse
metal oxides, such as, for example, zinc oxide, titanium dioxide,
achieves UV broad-band protection performance with a critical
wavelength .lamda..sub.amt of >380 nm (cf. Diffey in Int. J.
Cosm. Science 16, 47 (1994)).
[0147] Furthermore, the indanylidene compounds according to the
present invention can be combined alone or with other UV absorbers
used for the protection of technical products.
[0148] Examples of such UV absorbers are compounds from the series
of benzotriazoles, benzophenones, triazones, cinnamic esters and
oxalanilides.
[0149] The indanylidene compounds according to the present
invention are crystalline and have to be dissolved sufficiently in
cosmetic preparation to avoid the probelm of recrystallization
following a prolonged storage period. A sufficient amount of the
oil components customarily used in cosmetic preparations, liquid
oil-soluble UV absorbers or alcohols, e.g. ethanol, isopropanol or
1-butanol, is necessary to avoid recrystallization. More preference
is given to the use of the following oil components and/or UV
absorbers for achieving adequate solubility of combinations of the
indanylidene compounds according to the present invention:
ethylhexylmethoxycinnamate, isoamyl methoxycinnamate, octocrylene,
ethylhexyl salicylate, homosalate, menthyl anthranilate, padimate
O, diisopropyl adipate, C.sub.12-15alkyl benzoate (Witconol TN),
butylene glycol dicaprylate/dicaprate (Miglyol 8810),
cocoglycerides (Myritol 331), caprylic/capric triglycerides
(Miglyol 312), cetearyl isononanate (Cetiol SN), PVP/hexadecane
copolymer (Unimer U151), adipic acid/diethylene glycol/isononanoic
acid copolymer (Lexorez 100), propylene glycol
dicaprylate/dicaprate (Myritol PC), hexyl laurate (Cetiol A),
dicapryl ether (Cetiol OE), diethylhexyl naphthalate
(Hallbrite.RTM.TQ), butyloctyl salicylate (Hallbrite.RTM.BHB),
dibutyl adipate (Cetiol B), triethyl citrate (hydragen CAT),
propylene glycol dibenzoate (Finsolv PG 22), tributyl citrate,
dioctyl malate (Ceraphyl 45), dipropylen glycol dibenzoate
(Benzoflex 245), acetyltributyl citrate (Citroflex A-4),
acetyl/triethyl citrate (Citroflex A-2). The list of the oils which
can be used for the purposes of the present invention is not of
course intended to be limiting.
[0150] The use amount of all oil components in cosmetic emulsions
with compounds of the formula is 0.5 to 30% by weight, preferably 2
to 15% by weight. All said oil components and liquid oil-soluble UV
filters are excellent solvents for all crystalline oil-soluble UV
absorbers.
[0151] It is a serious drawback if UV absorbers leave behind marks
which cannot be washed out of items of clothing. In particular, it
is known that the UV-A absorber tert-butylmethoxydibenzoylmethane
produces marks on textiles which cannot be washed out. The
indanylidene compounds according to the present invention do not
have this drawback since a mark formed on textiles can be very
readily washed out.
[0152] Sunscreen products should be water-resistant in order that
sufficient UV protection is ensured for the user, in particular
children, while swimming or bathing. Combinations of the
indanylidene compounds according to the present invention satisfy
these requirements to a particularly good degree. In an O/W
emulsion containing 3% by weight of a combination of the
indanylidene compounds according to the present invention, 97%
substantivity of the UV absorber was measured following washing,
and in a W/O emulsion, 95%. Furthermore, the water resistance of
sun protection products containing water-soluble, mono- or
polysulfonated UV filters, such as, for example, Neo
Heliopan.RTM.AP, Maxoryl.RTM.SX, benzophenone-4, Neo
Heliopan.RTM.Hydro and the oil-soluble UV absorbers listed on pages
6-9 can be significantly increased as a result of combination with
compounds of the formula I.
[0153] It may also be of considerable advantage to combine the UV
absorbers mentioned according to the present invention with
chelating substances, as are listed, for example, in EP-A 313 305
and WO-94/04128, or with polyaspartic acid and
ethylenediamine-tetramethyl-phosphonic acid salts.
[0154] Cosmetic dermatological formulations for the purposes of the
present invention comprise one or more customary UV-A, UV-B and/or
broad-band filters as individual substances or in any mixtures with
one another, in the lipid phase and/or in the aqueous phase. They
are satisfactory products in every respect which are surprisingly
characterized by high UV-A protection performance and high sun
protection factor.
[0155] The present invention further provides for the use of the UV
absorbers according to the present invention in combination with
conventional UV absorbers for enhancing the protection against
harmful UV radiation beyond the extent of the protection achieved
using the same amounts of conventional or of UV filters according
to the present invention on their own (synergistic effect).
[0156] The total amount of UV filter substances (UV-A, UV-B and/or
broad-band filters) in the finished cosmetic or dermatological
preparations, whether as individual substance or in any mixtures
with one another, is advantageously chosen from the range from 0.1
to 30% by weight, preferably 0.1 to 10.0% by weight, more
preferably 0.5 to 5.0% by weight, based on the total weight of the
preparations.
[0157] In addition, cosmetic and dermatological preparations
according to the present invention advantageously, but not
obligatorily, comprise inorganic pigments based on finely disperse
metal oxides and/or other metal compounds which are insoluble or
sparingly soluble in water, in particular the oxides of titanium
(TiO.sub.2), zinc (ZnO), iron (e.g. Fe.sub.2O.sub.3), zirconium
(ZrO.sub.2), silicon (SiO.sub.2), manganese (e.g. MnO), aluminum
(A1.sub.2O.sub.3), cerium (e.g. Ce.sub.2O.sub.3), mixed oxides of
the corresponding metals, and mixtures of such oxides. These
pigments are X-ray-amorphous or non-X-ray-amorphous. More
preference is given to pigments based on TiO.sub.2. X-ray-amorphous
oxide pigments are metal oxides or semi-metal oxides which reveal
no or no recognizable crystalline structure in X-ray diffraction
experiments. Such pigments are often obtainable by flame reaction,
for example by reacting a metal or semi-metal halide with hydrogen
and air (or pure oxygen) in a flame.
[0158] In cosmetic, dermatological or pharmaceutical formulations,
X-ray-amorphous oxide pigments are used as thickeners and
tixotropic agents, flow auxiliaries for emulsion and dispersion
stabilization and as carrier substance (for example for increasing
the volume of finely divided powders). X-ray-amorphous oxide
pigments which are known and often used in cosmetic or
dermatological galerics are, for example, high-purity silicon
oxide. Preference is given to high-purity, X-ray-amorphous silicon
dioxide pigments with a particle size in the range from 5 to 40 nm
and an active substance (BET) in the range from 60 to 400
m.sup.2/g, preferably 150 to 300 m.sup.2/g, where the particles are
to be regarded as spherical particles of very uniform dimension.
Macroscopically, the silicon dioxide pigments are recognizable as
loose, white powders. Silicon dioxide pigments are sold
commercially under the name Aerosil.RTM. (CAS-No. 7631-85-9) or
Carb-O-Sil.
[0159] Advantageous Aerosil.RTM. grades are, for example,
Aerosil.RTM.0X50, Aerosil.RTM.130, Aerosil.RTM.150,
Aerosil.RTM.200, Aerosil.RTM.300, Aerosil.RTM.380, Aerosil.RTM.MQX
80, Aerosil.RTM. MOX 170, Aerosil.RTM.COK 84, Aerosil.RTM. R 202,
Aerosil.RTM.R 805, Aerosil.RTM.R 812, Aerosil.RTM.R 972,
Aerosil.RTM.R 974, Aerosil.RTM.R978.
[0160] According to the present invention, cosmetic or
dermatological light protection preparations comprise 0.1 to 20% by
weight, advantageously 0.5 to 10% by weight, more preferably 1 to
5% by weight, of X-ray-amorphous oxide pigments.
[0161] The non-X-ray-amorphous inorganic pigments are, according to
the present invention, advantageously in hydrophobic form, i.e.
have been surface-treated to repel water. This surface treatment
may involve providing the pigments with a thin hydrophobic layer by
processes known per se. Such a process involves, for example,
producing the hydrophobic surface layer by a reaction according to
n TiO.sub.2+m (RO).sub.3Si--R'.fwdarw.n TiO.sub.2 (surf.) where n
and m are stoichiometric parameters to be used as desired, and R
and R' are the desired organic radicals. Hydrophobicized pigments
prepared analogously to DE-A 33 14 742, for example, are
advantageous.
[0162] For example, mention may be made of TiO.sub.2 pigments, as
are sold under the tradename T805 from Degussa. Preference is also
given to TiO.sub.2Fe.sub.2O.sub.3 mixed oxides, as are supplied,
for example, under the trade name T817, also from Degussa.
[0163] The total amount of inorganic pigments, in particular
hydrophobic inorganic micropigments, in the finished cosmetic or
dermatological preparations is advantageously chosen from the range
from 0.1 to 30% by weight, preferably 0.1 to 10.0% by weight,
preferably 0.5 to 6.0% by weight, based on the total weight of the
preparations.
[0164] The cosmetic and/or dermatological formulations according to
the present invention can have the customary composition and can be
used for cosmetic and/or dermatological sun protection, and also
for the treatment, care and cleansing of the skin and/or of the
hair and as a make-up product in decorative cosmetics. Accordingly,
the preparations according to the present invention can, depending
on their formulation, be used, for example, as skin protection
cream, cleansing milk, sunscreen lotion, nourishing cream, day
cream or night cream, etc. In some instances, it is possible and
advantageous to use the preparations according to the present
invention as bases for pharmaceutical formulations. Preference is
given, in particular, to those cosmetic and dermatological
preparations in the form of a skin care or make-up product. Typical
embodiments are creams, gels, lotions, alcoholic and
aqueous/alcoholic solutions, emulsions or stick preparations. These
compositions may also comprise, as further auxilaries and
additives, mild surfactants, co-emulsifiers, superfatting agents,
pearlescent waxes, bodying agents, thickeners, polymers, silicone
compounds, fats, waxes, stabilizers, biogenic active ingredients,
deoderant active ingredients, antidandruff agents, film formers,
swelling agents, hydrotropic agents, preservatives, insect
repellants, tanning agents, artificial self-tanning agents (e.g.
dihydroxyacetone), stabilizers, perfume oils, dyes, antimicrobial
agents and the like.
[0165] For use, the cosmetic and dermatological preparations
according to the present invention are applied to the skin and/or
the hair in a sufficient amount in the manner customary for
cosmetics.
[0166] More preference is given to those cosmetic and
dermatological preparations in the form of a cosmetic composition
for the protection of the skin and hair. Advantageously, in
addition to UV-A, UV-B and/or broad-band filters used according to
the present invention, these can contain at least one inorganic
pigment, preferably an inorganic micropigment.
[0167] The cosmetic and dermatological preparations according to
the present invention can comprise cosmetic auxiliaries, as are
customarily used in such preparations, e.g. preservatives,
bactericides, perfumes, antifoams, dyes, pigments which have a
coloring action, thickeners, moisturizers and/or humectants, fats,
oils, waxes or other customary constituents of a cosmetic or
dermatological formulation, such as alcohols, polyols, polymers,
foam stabilizers, electrolytes, organic solvents or silicone
derivatives. Suitable nonionic emulsifiers or dispersants are the
group formed by polyglyceryl-2-dipolyhydroxystearate
(Dehymuls.RTM.PCPH), polyglyceryl-3-diisostearate
(Lameform.RTM.TGI), polyglyceryl-4 isostearate (Isolan.RTM.GI 34),
polyglyceryl-3 oleate, diisostearyl polyglyceryl-3 diisostearate
(Isolan.RTM.PDI), polyglyceryl-3 methylglucose distearate (Tego
Carey.RTM. 450), polyglyceryl-3 beeswax (Cera Bellina.RTM.),
polyglyceryl-4 caprate (polyglycerol caprate T2010/90),
polyglyceryl-3 catyl ether (Chimexane.RTM.NL), polyglyceryl-3
distearate (Cremophor.RTM.GS 32), polyglyceryl-2 stearate
(Hosfacerin.RTM.DGMS) and polyglyceryl polyricineoleate
(Admul.RTM.WOL 1403), and mixtures thereof.
[0168] The amounts of cosmetic or dermatological auxiliaries and
carrier substances and perfume which can be used in each case can
be determined easily by the person skilled in the art by simple
trial and error, depending on the nature of the product in
question.
[0169] An additional content of antioxidants is generally
preferred. According to the present invention, favorable
antioxidants which can be used ar all antioxidants customary or
suitable for cosmetic and/or dermatological applications.
[0170] The antioxidants are advantageously chosen from the group of
amino acids (e.g. glycine, histidine, tyrosine, tryptophan) and

ethers, sugars, nucleotides, nucleosides, peptides and lipids) of
the active ingredients suitable according to the present
invention.
[0171] The amount of the above-mentioned antioxidants (one or more
compounds) in the preparations is preferably 0.001 to 30% by
weight, more preferably 0.05 to 20% by weight, and most preferably
1 to 10% by weight, based on the total weight of the
preparation.
[0172] If vitamin E and/or derivatives thereof represent the
antioxidant(s), it is advantageous to choose their respective
concentrations from the range from 0.001 to 10% by weight, based on
the total weight of the formulation.
[0173] If vitamin A or vitamin A derivatives, or carotenes or
derivatives thereof represent the antioxidant(s), it is
advantageous to choose their respective concentrations from the

invention are advantageously chosen from the group of esters of
saturated and/or unsaturated, branched and/or unbranched
alkanecarboxylic acids having a chain length of from 3 to 30 carbon

[0189] A comprehensive description of the raw materials and active
ingredients used in cosmetic compositions is given in DE-A 199 19
630.
[0190] It could not have been foreseen that the indanylidene
compounds according to the present invention represent an excellent
selection compared with the compounds known from EP-A 823 418.
EXAMPLES
Photostability
[0191] By way of example, comparative measurements is between the
compounds of category A and the compounds of category B and the
combination with other standard commercial UV filters such as OMC
(=octyl methoxycinnamate) or BMDM
(=tert-butylmethoxydibenzoylmethane) are listed below. The
substances of category B demonstrate the improvement over the
substances of category A. The irradiation was carried out in a
Suntester from Heraeus at an irradiation intensity of 765 W/m.sup.2
(based on Global sensor). The values give the concentration
decrease of the UV filters in percentage following irradiation
(dose in J/cm.sup.2).
