Abstract

The use of acrylic functional siloxanes in hair treatment is disclosed. Acrylic functional siloxanes can be used as oxidizing agents in perms or formulated into hair care products such as shampoos or conditioners. They may be cured into/onto the hair using catalysts or radiation.

Claims

1. A method for treating hair comprising

(a) treating the hair with a reducing agent;

(b) rinsing the treated hair with water;

(c) applying to the hair a hair oxidizing composition comprising

(i) 0. 1 to 30 weight percent based on the hair oxidizing composition of an acrylic functional siloxane selected from the group consisting of ##STR10## and (ii) 0.01 to 5 weight percent based on the total weight of the hair oxidizing composition of a catalyst; and

(d) allowing the acrylic functional siloxane of (c) to react with the hair by exposing the hair to a source of heat;

wherein R is independently selected from the group consisting of an alkyl group consisting of 1 to 6 carbon atoms and an aryl group consisting of 6 to 10 carbon atoms;

Y is independently selected from the group consisting of ##STR11## where R¹ and R² are independently selected from the group consisting of straight and branched chain alkylene group consisting of 1 to 10 carbon atoms, and arylene group consisting of 6 to 10 carbon atoms;

any of said R¹ and R² groups optionally containing an ether oxygen or any functional substituant, unreactive with hair, within the aliphatic segments thereof;

R³ is selected from the group consisting of the hydrogen atom, an alkyl group of 1 to 10 carbon atoms and an aryl group consisting of 6 to 10 carbon atoms; and

A is the group ##STR12## where R⁴ is selected from the group consisting of the hydrogen atom and the methyl group; and

x has the value of 1 to 10,000 and

y has the value of 1 to 100.

2. A method as claimed in claim 1 wherein the acrylic functional siloxane is of the formula ##STR13## where R is --CH₃, Y is the group ##STR14## and R² is the group --CH₂ CH₂ --.

3. A method as claimed in claim 1 wherein the acrylic functional siloxane is of the formula ##STR15## where R is --CH₃ , Y is the group ##STR16## and R² is the group --CH₂ CH₂ --.

4. The method of claim 1 wherein the acrylic functional siloxane is present in a range from 1 to about 20 weight percent of the hair oxidizing composition.

5. The method of claim 1 wherein the acrylic functional siloxane is present in a range from 1 to about 6 weight percent of the hair oxidizing composition.

7. The method as claimed in claim 1 wherein the catalyst is selected from the group consisting of amines, ferrous containing catalysts and free radical initiators.

8. The method as claimed in claim 1 wherein the catalyst is triethanolamine.

9. The method as claimed in claim 1 wherein the catalyst is hydrogen peroxide.

10. The method as claimed in claim 1 wherein there is also present in the hair oxidizing composition (iii) a delivery means.

11. The method as claimed in claim 1 wherein the delivery means is selected from the group consisting of solvent, water, isoparafins, low molecular weight alkanes, silicones, non-polar, solvents, propellants and emulsions.

12. The method as claimed in claim 11 wherein the delivery means is an alcohol.

6. A method for treating hair comprising

(a) treating the hair with a reducing agent;

(b) rinsing the treated hair with water;

(c) applying to the hair a hair oxidizing composition comprising

(i) 0.1 to 30 weight percent based on the hair oxidizing composition of an acrylic functional siloxane selected from the group consisting of ##STR17## and (ii) 0.01 to 5 weight percent based on the hair oxidizing composition of a photo-initiator; and

(d) allowing the acrylic functional siloxane of (c) to react with the hair by exposing the hair to a source of radiation;

wherein R is independently selected from the group consisting of an alkyl group consisting of 1 to 6 carbon atoms and an aryl group consisting of 6 to 10 carbon atoms;

Y is independently selected from the group consisting of ##STR18## where R¹ and R² are independently selected from the group consisting of straight and branched chain alkylene group consisting of 1 to 10 carbon atoms, and arylene group consisting of 6 to 10 carbon atoms;

any of said R¹ and R² groups optionally containing an ether oxygen or any functional substituant, unreactive with hair, within the aliphatic segments thereof;

R³ is selected from the group consisting of the hydrogen atom, an alkyl group of 1 to 10 carbon atoms and an aryl group consisting of 6 to 10 carbon atoms; and

A is the group ##STR19## where R⁴ is selected from the group consisting of the hydrogen atom and the methyl group; and

x has the value of 1 to 10,000 and

y has the value of 1 to 100.

13. The method as claimed in claim 6 wherein the acrylic functional siloxane is of the formula ##STR20## where R is --CH₃, Y is the group ##STR21## and R2 is the group --CH₂ CH₂ --.

14. The method as claimed in claim 6 wherein the acrylic functional siloxane is of the formula ##STR22## where R is --CH₃, Y is the group ##STR23## and R2 is the group --CH₂ CH₂ --.

15. The method as claimed in claim 6 wherein the source of radiation is electron beam radiation.

16. The method as claimed in claim 6 wherein there is also present in the hair oxidizing composition (iii) a delivery means.

17. The method as claimed in claim 6 wherein the delivery means is selected from the group consisting of solvent, water, isoparafins, low molecular weight alkanes, silicones, non-polar solvents, propellants and emulsions.

18. The method as claimed in claim 17 wherein the delivery means is an alcohol.
