Abstract

The present invention relates to decorative cosmetic compositions comprising special polyurethanes or aqueous dispersions thereof and constituents providing decorative effects.

First claim

The invention claimed is:

1. A decorative cosmetic composition comprising at least one polyurethane, wherein the decorative composition comprises 0.1 to 20% by weight of the at least one polyurethane, and wherein the decorative composition is face make-up, blusher, rouge, mascara, eyeliner, kohl pencil, eye shadow, lipstick, or lipgloss, and
one or more constituents, which produce a coloring, a glitter, and/or a metallic effect, wherein the at least one polyurethane is obtainable by reacting one or more water-insoluble,
non-water-dispersible, isocyanate-functional polyurethane prepolymers A) with two or more amino-functional compounds B),
wherein the two or more amino-functional compounds B) include at least one amino-functional compound B2), which has ionic and/or ionogenic groups, and an amino-functional compound B1), which has no ionic and/or ionogenic group,

wherein the decorative cosmetic composition provides color-imparting, glitter-imparting, and/or metallic-imparting effect on skin and/or hair,
wherein the composition is in the form of oil-in-water, water-in-oil, water-in-silicone oil, silicone oil-in-water, oil-in-water-in-oil, or water-in-oil-in-water emulsions, and
wherein the isocyanate-functional polyurethane prepolymers A) are prepared from
A1) organic polyisocyanates, which are selected from aliphatic, aromatic or cycloaliphatic polyisocyanates with an NCO functionality of greater than or equal to 2,
A2) polymeric polyols with number-average molecular weights of from 400 to 8000 g/mol, which is determined by gel permeation chromatography relative to polystyrene standard in tetrahydrofuran at 23° C., and OH functionalities of 1.5 to 6, and which are selected from one or more of the group consisting of polyether polyols, polycarbonate polyols, polyether-polycarbonate polyols, and polyester polyols,
A3) optionally hydroxy-functional compounds with molecular weights of 62 to 399 g/mol, and
A4) optionally nonionic hydrophilizing agents,
wherein the amino-functional compounds B) are selected from primary and/or secondary diamines.

2. The decorative cosmetic composition according to claim 1 , wherein the isocyanate-functional polyurethane prepolymers A) are prepared from
A1) organic polyisocyanates, which are selected from aliphatic, aromatic or cycloaliphatic polyisocyanates with an NCO functionality of greater than or equal to 2,
A2) polymeric polyols with number-average molecular weights of from 400 to 8000 g/mol, which is determined by gel permeation chromatography relative to polystyrene standard in tetrahydrofuran at 23° C., and OH functionalities of 1.5 to 6, and which are selected from one or more of the group consisting of polyether polyols, polycarbonate polyols, polyether-polycarbonate polyols, and polyester polyols,
A3) optionally hydroxy-functional compounds with molecular weights of 62 to 399 g/mol, and
A4) the nonionic hydrophilizing agents.

3. The decorative cosmetic composition according to claim 2 , wherein the nonionic hydrophilizing agents are polyoxyalkylene ethers having isocyanate- reactive hydroxyl groups.

4. The decorative cosmetic composition according to claim 1 , wherein the nonionic hydrophilizing agents are polyoxyalkylene ethers having isocyanate-reactive hydroxyl groups.

5. The decorative cosmetic composition according to claim 1 , wherein the two or more amino-functional compounds B) include ethylenediamine and diaminosulphonate.

6. A cosmetic method for producing a decorative effect on skin and optionally hair, comprises
applying a composition consisting of
at least one polyurethane,
one or more constituents, which produce a coloring, a glitter, and/or a metallic effect to the skin and optionally hair,
wherein the polyurethane is obtainable by reacting one or more water-insoluble, non-water-dispersible, isocyanate-functional polyurethane prepolymers A) with two or more amino-functional compounds B),
wherein the two or more amino-functional compounds B) include at least one amino-functional compound B2), which has ionic and/or ionogenic groups, and an amino-functional compound B 1), which has no ionic and/or ionogenic group,

wherein the decorative effect is color-imparting, glitter-imparting and/or metallic-imparting,
wherein the one or more constituents comprise a dye,
wherein the composition is in the form of oil-in-water, water-in-oil, water-in-silicone oil, silicone oil-in-water, oil-in-water-in-oil, or water-in-oil-in-water emulsions, and
wherein the isocyanate-functional polyurethane prepolymers A) are prepared from
A1) organic polyisocyanates, which are selected from aliphatic, aromatic or cycloaliphatic polyisocyanates with an NCO functionality of greater than or equal to 2,
A2) polymeric polyols with number-average molecular weights of from 400 to 8000 g/mol, which is determined by gel permeation chromatography relative to polystyrene standard in tetrahydrofuran at 23° C., and OH functionalities of 1.5 to 6, and which are selected from one or more of the group consisting of polyether polyols, polycarbonate polyols, polyether-polycarbonate polyols, and polyester polyols,
A3) optionally hydroxy-functional compounds with molecular weights of 62 to 399 g/mol, and
A4) optionally nonionic hydrophilizing agents, wherein the amino-functional compounds B) are selected from primary and/or secondary diamines,

optionally moisturisers, water, solvents, waxes, stabilizers, antioxidants, photoprotective agents, emulsifiers, humectants, sensory additives, UV filters, polymer dispersions based on polyacrylates, pigments, and combinations thereof.

7. The cosmetic method according to claim 6 , wherein the polyurethane contains at least one sulphonic acid and/or sulphonate group.

8. The cosmetic method according to claim 6 , wherein the method comprises application of the composition to the skin, wherein the composition at least partially remains on it.

9. The cosmetic method according to claim 6 wherein the amino-functional compound B2) is 2-(2-aminoethylamino)ethanesulphonic acid and/or salts thereof.

10. The cosmetic method according to claim 6 , wherein the amino-functional compound B1) is a diamine which has no ionic and/or ionogenic groups.

11. The cosmetic method according to claim 6 , wherein the polyurethane contains at least one sodium sulphonate group.

12. The cosmetic method according to claim 6 , wherein the composition comprises 0.1 to 20% by weight of the polyurethane.

13. The cosmetic method according to claim 6 , wherein the dye is selected from the group consisting of lipophilic dyes, hydrophilic dyes, pigments, and mother of pearl.

14. The cosmetic method according to claim 6 , wherein the composition comprises 1 to 30% by weight of the dye.
