Cosmetic compositions containing crosslinkable polymers
View Patent ↗A cosmetic composition which provides a semi-permanent, crosslinked film on a keratinous substrate comprising a film-forming polymer having functional groups capable of cross-linking upon exposure to a cross-linking agent reactive with the functional groups; a cross-linking agent reactive with the functional groups of the film-forming polymer; a dissipatable blocking agent which is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer.
1. A composition for treating hair and applying semi-permanent crosslinked film thereon, comprising:
(a) a film-forming polymer having functional groups capable of cross-linking upon exposure to a cross-linking agent reactive with said functional groups,
(b) a cross-uniting agent reactive with said functional groups of the film-forming polymer,
(c) a dissipatable blocking agent which (i) is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, (ii) after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer.
2. The composition of claim 1 which is for cleansing, conditioning, or coloring hair.
3. The composition of claim 1 which is a shampoo.
4. The composition of claim 3 comprising 0.5-30% of a cleansing surfactant and 10-95% water.
5. The composition of claim 4 wherein the cleansing surfactant is an anionic surfactant.
6. The composition of claim 1 which is a hair conditioner.
7. The composition of claim 6 comprising 0.1-20% of a cationic agent and 5-95% water.
8. The composition of claim 7 further comprising 0.1-30% fatty alcohol and 0.001-10% nonionic surfactant.
9. The composition of claim 1 wherein the functional groups of the film-forming polymer are carboxylic acid, hydroxyl, or combinations thereof.
10. The composition of claim 2 wherein the film-forming polymer is comprised of monomers selected from the group consisting of:
wherein R 1 is H or a C 1-30 straight or branched chain alkyl, aryl, or aralkyl; R 2 is H or C 1-30 straight or branched chain alkyl, aryl, or aralkyl; and M is a C 1-30 straight or branched chain alkyl which is unsubstituted, or substituted with one or more substitutents which are hydroxyl, halogen, carboxyl, acetoacetoxy, or combinations thereof; pyrrolidone, or a Substituted or unsubstituted aromatic, alicylic, or bicyclic ring where the substitutents are C 1-30 straight or branched chain alkyl.
11. The composition of claim 1 wherein the cross-linking agent is an aliphatic or aromatic dihydric alcohol, an alphatic or aromatic polyol, a metal ion having a coordination number ranging from 2 to 4, amine, or mixtures thereof.
12. The composition of claim 1 wherein the dissipatable blocking agent comprises a cosmetically acceptable carrier phase comprising a solvent.
13. The composition of claim 12 wherein the solvent in the carrier phase comprise water, a non-aqueous volatile solvent, or mixtures thereof.
14. A composition for conditioning hair and applying semi-permanent crosslinked film thereon, comprising:
(a) a film-forming polymer having functional groups capable of cross-linking upon exposure to a cross-linking agent reactive with said functional groups,
(b) a cross-linking agent reactive with said functional groups of the film-forming polymer
(c) a dissipatable blocking agent which (i) is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, (ii) after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer,
at least one hair conditioning ingredient; and
water.
15. The composition of claim 14 wherein the at least one hair conditioning agent comprises one or more cationic quaternary ammonium compounds, fatty alcohols, or mixtures thereof.
16. A composition for cleansing hair and applying semi-permanent crosslinked film thereon, comprising:
(a) film-forming polymer having functional groups capable of cross-linking upon exposure to a cross-linking agent reactive with said functional groups,
(b) a cross-linking agent reactive with said functional groups of the film-forming polymer,
(c) a dissipatable blocking agent which (i) is operable prior to dissipation, to block the cross-linking agent from cross-linking the functional groups of the film-forming polymer, and which, (ii) after dissipation, leaves the cross-linking agent free to cross-link the functional groups of the film-forming polymer,
at least one cleansing surfactant; and
water.
17. The composition of claim 16 wherein the cleansing surfactant comprises an anionic surfactant, a nonionic surfactant, an amphoteric surfactant, a zwitterionic surfactant, or mixtures thereof.
