Use of xanthan gum as a hair fixative
View Patent ↗The present invention is directed to the use of xanthan gum, particularly heat treated xanthan gum, as a fixative in hair cosmetic compositions. Xanthan gum is advantageous in that it may be used with other hair fixatives and provides rheology modifying and other properties including excellent stiffness, gloss, dry comb, wet comb, non-flake, anti-static, feel and high humidity curl retention.
1. A cosmetic composition comprising a fixative effective amount of heat treated xanthan gum for fixing hair, and a second fixative polymer comprising polyvinylpyrrolidone or a copolymer of polyvinylpyrrolidone:
wherein the xanthan gum has been heat treated at a temperature of about 60° C. or more for about 30 minutes or more to a moisture content of about 8% or less,
wherein the heat-treated xanthan gum has a viscosity of about 4000 cps or greater and a crossover strain of about 100 or less in a 1% aqueous solution,
wherein the cosmetic composition is a hair fixative cosmetic composition, and
wherein the fixative cosmetic composition provides an improved high humidity curl retention of hair over fixative cosmetic composition without the heat treated xanthan gum.
2. The composition of claim 1 , wherein the temperature is at least 100° C.
3. The composition of claim 2 , wherein the temperature is at least 105° C.
4. The composition of claim 1 , wherein the moisture content is about 1% or less.
5. The composition of claim 1 , wherein the heat treatment is for about one hour or more.
6. The composition of claim 5 , wherein the heat treatment is for about 2.5 hours or more.
7. The composition of claim 1 , wherein the heat treatment is at a temperature of about 105° C. or more for about 2.5 hours or more to a moisture content of about 1% or less.
8. The composition of claim 1 , wherein the composition is selected from the group consisting of a spray, a mousse, a hair lotion, a cream, a pomade, and a gel.
9. The composition of claim 8 , wherein the composition is a gel.
10. The composition of claim 1 wherein the heat treated xanthan gum has a viscosity of about 8000 cps or more and a turbidity of no more than about 100 NTU (Nephelometric Turbidity Units).
11. The composition of claim 1 further comprising a fixative polymer selected from the group consisting of acrylates copolymer, octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer, acrylates/octylacrylamide copolymer, VA/crotonates/vinyl Neodeanoate copolymer, poly(N-vinyl acetamide), poly(N-vinyl formamide), polyurethane, corn starch modified, sodium polystyrene sulfonate, polyquaternium-4, polyquaternium-10 and polyurethane/acrylates copolymer.
12. A method of preparing the composition of claim 1 , comprising dispersing the xanthan gum in water; and mixing in other hair cosmetic components.
13. A method of providing fixative properties to hair comprising applying the composition of claim 1 to the hair.
14. A method of providing curl retention of hair under high humidity conditions comprising applying the composition of claim 1 to hair.
15. The composition of claim 1 , wherein the composition is a surfactant-free hair mousse.
16. A cosmetic composition comprising:
a fixative, wherein the fixative is essentially heat treated xanthan gum wherein the heat treated xanthan gum has been heat treated to a moisture content of about 8% or less, wherein the heat-treated xanthan gum has a viscosity of about 4000 cps or greater and a crossover strain of about 100 or less in a 1% aqueous solution; and
a second fixative polymer comprising polyvinylpyrrolidone or a copolymer of polyvinylpyrrolidone;
wherein the cosmetic composition is a hair fixative cosmetic composition and provides an improved high humidity curl retention.
17. The composition of claim 16 , wherein the composition is selected from the group consisting of a spray, a mousse, a hair lotion, a cream, a pomade, and a gel.
18. The composition of claim 17 , wherein the composition is a gel.
19. The composition of claim 16 characterized by a viscosity of about 8000 cps or more, a high humidity curl retention of about 80% or more and a turbidity of no more than about 100 NTU (Nephelometric Turbidity Units).
20. The composition of claim 16 , wherein the composition is a surfactant-free hair mousse.
21. The composition of claim 1 wherein the second fixative polymer is selected from the group consisting of PVP/dimethylaminoethylmethacrylate copolymer, PVP/vinylcaprolactam/DMAPA acrylates copolymer, Vinyl caprolactam/PVP/dimethylaminoethyl methacrylates copolymer, polyvinylpyrrolidone, PVP/vinyl acetate copolymer, PVP/acrylates copolymer, vinylcaprolactam/PVP/dimethylaminoethyl methacrylate.
22. The composition of claim 16 wherein the second fixative polymer is selected from the group consisting of PVP/dimethylaminoethylmethacrylate copolymer, PVP/vinylcaprolactam/DMAPA acrylates copolymer, Vinyl caprolactam/PVP/dimethylaminoethyl methacrylates copolymer, polyvinylpyrrolidone, PVP/vinyl acetate copolymer, PVP/acrylates copolymer, vinylcaprolactam/PVP/dimethylaminoethyl methacrylate.
23. The composition of claim 1 wherein the second fixative polymer is polyvinylpyrrolidone.
24. The composition of claim 16 wherein the second fixative polymer is polyvinylpyrrolidone.
