Abstract

The instant disclosure generally relates to a bicomponent composition for coloring mammalian or synthetic keratin fibers, the bicomponent composition comprising first, second, components. The first component includes an organic polymer, the second component includes a pretreatment base compound. One or more of the components includes pigment microparticles. The bicomponent composition combines upon application to treated material such as hair, forms a solid coating thereon and has a substantially long color fastness following development (setting). Methods of using such compositions are also described herein.

Claims (37)

1. A bicomponent composition for coloring keratin material comprising a first component of at least one organic copolymer with functional groups, at least one pigment and a second component comprising a base compound having functional groups capable of forming dipolar or electrostatic interactions with the organic copolymer,

wherein:

the organic copolymer comprises repeating units of at least one hydrophobic olefinic carboxylate ester monomer and at least one hydrophilic olefinic monomer;

the hydrophobic olefinic carboxylate ester monomer comprises an ester of (meth)acrylic acid or crotonic acid, or a combination thereof and a linear or branched alkanol of 1 to 30 carbons or a combination thereof;

the hydrophilic olefinic monomer comprises a hydroxy alkyl ester of an olefinic carboxylic acid and a linear or branched alkyl diol of 2 to 24 carbons, or an aminoalkyl ester of an olefinic carboxylic acid and a linear or branched amino alkyl alcohol of 2 to 24 carbons, or an olefinic acid, or a combination of any two or more of the hydroxyl alkyl ester, the amino alkyl ester and the olefinic acid; and

the olefinic acid comprises (meth)acrylic acid, crotonic acid, maleic acid, fumaric acid, itaconic acid or gluconic acid or a combination of any two or more of the olefinic acids; and,

the base compound comprises an aminosilane, aminosiloxane, or mixture thereof.

2. A bicomponent composition of claim 1 wherein the first and second components are separate and one or both of the components further comprises a medium.

3. A bicomponent composition of claim 1 wherein the weight average molecular weight of the base compound is in a range of about 150 Da to 2 kDa.

4. A bicomponent composition of claim 1 wherein the organic copolymer further comprises at least one olefin monomer, wherein:

the olefin monomer has the formula

H 2 C═CHR

wherein R is selected from linear or branched alkyl of one to six carbons, unsubstituted phenyl or phenyl substituted by a linear or branched alkyl of 1 to six carbons, carboxylic acid, methyl or ethyl carboxylate, carboxamide or hydroxyl.

5. A bicomponent composition of claim 4 wherein the olefinic acid is (meth)acrylic acid or crotonic acid.

6. A bicomponent composition of claim 5 wherein the olefinic acid is (meth)acrylic acid.

7. A bicomponent composition according to claim 1 wherein the olefinic acid is (meth)acrylic acid or crotonic acid.

8. A bicomponent composition of claim 7 wherein the olefinic acid is (meth)acrylic acid.

9. A bicomponent composition of claim 4 wherein the olefin monomer is styrene or carboxystrene methyl or ethyl ester.

10. A bicomponent composition of claim 4 wherein the olefin monomer is hydroxystyene, carboxystyrene or carboxamidostyrene.

11. A bicomponent composition according to claim 4 wherein the weight percent of the base compound is 0.1-5 wt. % relative to the total composition.

12. A bicomponent composition of claim 1 wherein the weight percent of the base compound is 0.1-5 wt. % relative to the total composition.

13. A bicomponent composition of claim 1 wherein

the organic polymer has an acid value of from about zero to about 250;

the organic polymer has a glass transition temperature of from about −120° C. to about −40° C.;

the organic polymer has a weight average molecular weight in the range of about 2 KDa to about 10 MDa; and

the composition has a pH of from about 3 to about 12.

14. A bicomponent composition of claim 4 wherein

the organic polymer has an acid value of from about zero to about 250;

the organic polymer has a glass transition temperature of from about −120° C. to about −40° C.;

the organic polymer has a weight average molecular weight in the range of about 2 KDa to about 10 MDa; and

the composition has a pH of from about 3 to about 12.

15. A kit comprising separate compartments in which the first component and the second component of claim 1 are separately contained, wherein the first component, the second component, or both comprise pigment microparticles.

16. A method for coloring keratin material comprising applying first to the keratin material the second component of claim 15 to form a pretreated keratin material, then applying the first component of claim 15 to the pretreated keratin material and drying the coated keratin material with optional heat to form a colored coating on the keratin material.

17. A method of claim 16 wherein the first and second components are applied as foams to portions of the keratin material.

18. A kit comprising separate compartments in which the first component and the second component of claim 4 are separately contained, wherein the first component, the second component, or both comprise pigment microparticles.

19. A method for coloring keratin material comprising applying first to the keratin material the second component of claim 18 to form a pretreated keratin material, then applying the first component of claim 18 to the pretreated keratin material and drying the coated keratin material with optional heat to form a colored coating on the keratin material.

20. A method of claim 19 wherein the first and second components are applied as foams to portions of the keratin material.
