Hair care compositions
View Patent ↗Compositions and methods are disclosed for imparting a long-wearing shine to keratin fibers, including hair. The compositions comprise an aminosilicone polymer having a viscosity from about 800 to about 1,600 mm 2 /s at 25° C., and a functional group equivalent weight from about 8,000 to about 14,000 g/mol. The compositions comprise an aminosilicone polymer and optionally a shine enhancer. The compositions are useful for imparting a long-wearing shine to hair.
1. A method for imparting a long-wearing shine to hair, comprising applying to the hair a composition comprising an aminosilicone polymer that has the structure:
where
x is an integer from 1 to 6,
y is an integer from 1 to 6,and
m and n are independently each an integer from 1 to 5,000 and are selected to provide a viscosity of about 1,200 mm 2 /s at 25° C., and a functional group equivalent weight (FGEW) of about 11,000 g/mol, and a suitable vehicle.
2. The method according to claim 1 , wherein said aminosilicone polymer has a refractive index greater than 1.4 at 25° C.
3. The method according to claim 1 , wherein x is 3 and y is 2.
4. The method according to claim 1 , wherein said composition further comprises a film former.
5. The method according to claim 1 , wherein said composition is substantially anhydrous.
6. The method according to claim 1 , wherein said composition further comprises a shine enhancer.
7. The method according to claim 6 , wherein said shine enhancer is an aryl-silicone having a refractive index greater than 1.4 at 25° C.
8. The method according to claim 6 , wherein said shine enhancer is a phenyltrimethicone or dimethicone.
9. A hair care composition comprising:
(a) from about 1 to about 25 percent by weight of an aminosilicone polymer that has the structure:
where
x is an integer from 1 to 6,
y is an integer from 1 to 6,and
m and n are independently each an integer from 1 to 5,000 and are selected to provide a viscosity of about 1,200 mm 2 /s at 25° C., and a functional group equivalent weight of about 11,000 g/mol, and
(b) a suitable vehicle.
10. The composition according to claim 9 , wherein said aminosilicone has a refractive index greater than 1.4 at 25° C.
11. The composition according to claim 9 , wherein x is 3 and y is 2.
12. The composition according to claim 9 , further comprising a shine enhancer.
13. The composition according to claim 12 , wherein said shine enhancer is a phenyltrimethicone or dimethicone.
