Durable styling compositions and the uses thereof
Compositions are disclosed that impart one or more durable hair styling benefits. The durable styling compositions comprise at least a first compound having anhydride, diacid, diester, or half-acid/half-ester functionality, and a second compound having at least one amine moiety or hydroxyl functional group. In one embodiment the durable styling composition takes the form of a leave-in product. The durable styling compositions are heat-activated, which may be accomplished through the use of a heated styling tool like a flat-iron, curling iron, and/or hair dryer. The benefits include shine, conditioning, softness, defrizzing, and improved hair alignment, and endure for up to 5 wash cycles or more without having to reapply the durable styling composition nor heat.
1. A method of providing a durable hair style comprising the steps:
applying to the hair a composition consisting of:
a poly(vinyl methyl ether-co-maleic anhydride), and
a polyimide-1; and
a blend of caprylyl glycol and phenoxyethanol; and
heating the hair to a temperature ranging from about 90° C. to about 250° C., wherein the composition is left in the hair to exhibit at least one of greater shine, conditioning, defrizzing, decurling, dewaving, curling, waving, softness, ease of styling, volume improvement, smooth feeling, improved hair alignment, manageability, color protection, or humidity resistance.
2. The method of claim 1 , wherein the composition has a pH of from 3 to 11.
3. The method of claim 2 , wherein the composition has a pH of from 3 to 7.
4. The method of claim 2 , wherein the composition has a pH of from 7 to 11.
5. The method of claim 1 , wherein the composition has a pH of 12.
6. The method of claim 1 , wherein the composition has a pH of 13.
7. The method of claim 1 , wherein the composition further comprises about 93.92% to about 98.17% water.
8. The method of claim 1 , wherein the composition further comprises a solvent comprising water and a lower molecular weight alcohol.
9. A method of providing a durable hair style comprising the steps:
applying to the hair a composition consisting of:
a poly(vinyl methyl ether-co-maleic anhydride) copolymer selected from the group consisting of a poly(vinyl methyl ether-co-maleic anhydride), an ethyl ester of a poly(vinyl methyl ether-co-maleic anhydride), a butyl ester of a poly(vinyl methyl ether-co-maleic anhydride), an isopropyl ester of a poly(vinyl methyl ether-co-maleic anhydride), and combinations thereof,
a polyimide-1,
water,
sodium hydroxide, and
a blend of caprylyl glycol and phenoxyethanol; and
heating the hair at a temperature ranging from about 90° C. to about 250° C.
10. The method of claim 9 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is a poly(vinyl methyl ether-co-maleic anhydride).
11. The method of claim 9 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is an ethyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
12. The method of claim 9 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is of a butyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
13. The method of claim 9 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is of an isopropyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
14. A method of providing a durable hair style comprising the steps:
applying to the hair a composition consisting of:
a poly(vinyl methyl ether-co-maleic anhydride) copolymer selected from the group consisting of a poly(vinyl methyl ether-co-maleic anhydride), an ethyl ester of a poly(vinyl methyl ether-co-maleic anhydride), a butyl ester of a poly(vinyl methyl ether-co-maleic anhydride), an isopropyl ester of a poly(vinyl methyl ether-co-maleic anhydride), combinations thereof, and
a polyimide-1; and
a blend of caprylyl glycol and phenoxyethanol; and
heating the hair at a temperature ranging from about 90° C. to about 250° C.
15. The method of claim 14 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is an ethyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
16. The method of claim 14 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is a butyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
17. The method of claim 14 , wherein the poly(vinyl methyl ether-co-maleic anhydride) copolymer is an isopropyl ester of a poly(vinyl methyl ether-co-maleic anhydride).
