Abstract

The present invention is directed to an aerosol cosmetic composition, temporary keratin fiber dyeing method, and device which employ pigments and organopolysiloxane graft polymers in an environment with low water content. Good dyeing properties combined with wear and water resistance as well as good removability upon 1 shampooing were found.

First claim

The invention claimed is:

1. A cosmetic aerosol composition for keratin fibers, comprising:
one or more organopolysiloxane graft polymer(s) selected from the group consisting of Polysilicone 9 and Polysilicone 28,
one or more pigment(s),
one or more cosmetically acceptable organic solvent(s) with a boiling point in the range of more than 50° C. to 120° C. under atmospheric conditions, and
one or more propellant(s) at a total concentration of at least 50% by weight, calculated to a total weight of the composition,
wherein the composition comprises less than 5% by weight of water, calculated to the total weight of the composition.

2. The composition according to claim 1 , wherein the one or more pigment(s) are inorganic pigments and/or organic pigments.

3. The composition according to claim 1 , wherein the one or more organic pigments are salts of organic dyes being at least partially insoluble in the organic solvent under atmospheric conditions and 25° C., and/or organic lakes, and/or their mixtures.

4. The composition according to claim 1 , wherein the one or more pigment(s) are inorganic pigments that are single constituent material pigments and/or composite material pigments.

5. The composition according to claim 1 , wherein the one or more pigment(s) comprise an inorganic pigment that is bismuth oxychloride and/or bismuth oxychloride deposited on mica cores.

6. The composition according to claim 1 , comprising pigments at a total concentration of 0.01% to 10% by weight, calculated to the total weight of the composition.

7. The composition according to claim 1 , wherein the one or more propellant(s) is/are selected from the group consisting of carbon dioxide, dimethylether, n-butane, iso-butane, liquefied petroleum gas, and hydrofluorcarbon gases, and the total concentration of propellants is in the range of 55% to 90% by weight, calculated to the total weight of the composition.

8. The composition according to claim 1 , further comprising one or more organic solvent(s) with a boiling point in the range of 25° C. to 50° C. under atmospheric conditions, wherein a total concentration of propellants and organic solvents with a boiling point in the range of 25° C. to 50° C. is in the range of more than 50% to 95% by weight, calculated to the total weight of the composition.

9. The composition according to claim 1 , wherein a total concentration of organic solvent(s) with a boiling point in the range of more than 50° C. to 120° C. under atmospheric conditions is in a range of 5% to 45% by weight, calculated to the total weight of the composition.

10. The composition according to claim 1 , further comprising one or more lipophilic organic compound(s) which is/are immiscible and/or insoluble with water at 25° C. and atmospheric conditions and which is/are different from the organopolysiloxane graft polymer.

11. The composition according to claim 10 , wherein the one or more lipophilic compound(s) is/are selected from the group consisting of fatty alcohols, fatty acids, waxes, vegetable oils, petrolatum based products, silicones, aminated silicones, and compounds according to structure:

wherein R1 is linear or branched, saturated or unsaturated alkyl with C11 to C21 and optionally modified with 1 hydroxyl group, and R2 is linear or branched, saturated or unsaturated alkyl with C3 to C18.

12. The composition according to claim 1 , further comprising one or more hair setting polymer(s) that is/are non-ionic and/or cationic and/or anionic and/or amphoteric hair setting polymers.

13. The composition according to claim 1 , further comprising one or more hair direct dye(s) different from pigments, that is/are cationic and/or anionic and/or non-ionic hair direct dyes.

14. A method for dyeing keratin fibers, comprising:
a) optionally washing and drying the keratin fibers,
b) applying the cosmetic aerosol composition of claim 1 to dry keratin fibers, and
d) optionally treating the keratin fibers with a comb, brush, flat-iron and/or round-iron at a temperature in the range of 50° C. to 230° C.

15. The composition according to claim 1 , wherein the one or more organic pigments are organic lakes selected from the group consisting of Blue 1 lake, Yellow 7 lake, Green 3 lake, Orange 4 Lake, Orange 5 Lake, Orange 10 Lake, Red 4 Lake, Red 6 Lake, Red 7 Lake, Red 21 Lake, Red 22 Lake, Red 27 Lake, Red 28 Lake, Red 30 Lake, Red 31 Lake, Red 33 Lake, Red 34 Lake, Red 40 Lake, Yellow 5 Lake, Yellow 6 Lake, Yellow 7 Lake, and Yellow 10 Lake.

16. The composition according to claim 1 , comprising pigments at a total concentration of 1% to 5% by weight, calculated to the total weight of the composition.

17. The composition according to claim 1 , wherein the one or more propellant(s) is/are selected from the group consisting of carbon dioxide, dimethylether, n-butane, iso-butane, liquefied petroleum gas, and hydrofluorcarbon gases, and the total concentration of propellants is in the range of 60% to 85% by weight, calculated to the total weight of the composition.

18. The composition according to claim 10 , wherein the one or more lipophilic compound(s) comprise ethylhexyl hydroxystearate.
