Abstract

A composition for providing a film on keratin fibres, the composition comprising: a film-forming aminosilicone polymer; a silicone resin; an ether of a water-soluble polyhydric alcohol; a thickening system comprising a deposition enhancer and a thickening polymer; one or more coloured materials or one or more pigments; water; 2-phenoxyethanol and/or phenylmethanol; wherein the composition is substantially free of esters of parahydroxybenzoic acid; and wherein the composition is substantially free of isothiazolinone compounds. Also, associated methods, kits and uses.

First claim

What is claimed is:

1 . A composition for providing a film on keratin fibres, the composition comprising:
(a) an aminosilicone polymer, wherein the aminosilicone polymer comprises amino sidechains, and wherein the aminosilicone polymer as a weight average molecular weight of from about 10,000 Dalton to about 60,000 Dalton; (b) a silicone resin; (c) an ether of a water-soluble polyhydric alcohol; (d) a thickening system comprising:
a deposition enhancer, wherein the deposition enhancer is a hydrophilic and non-ionic polymer, and wherein the deposition enhancer has a weight average molecular weight of at least about 300,000 Dalton to about 7,500,000 Dalton;
a thickening polymer, wherein the thickening polymer has a weight average molecular weight of at least about 10,000 Dalton, and wherein the thickening polymer is a cationic thickening polymer or is a non-ionic thickening polymer;
(e) one or more coloured materials or one or more pigments; (f) water; (g) 2-phenoxyethanol and/or phenylmethanol; wherein the composition is substantially free of esters of parahydroxybenzoic acid; and wherein the composition is substantially free of isothiazolinone compounds.

2 . The composition of claim 1 , wherein the composition comprises one or more pigments having an average particle size of from about 5 um to about 60 um.

3 . The composition of claim 1 , wherein the (c) ether of a water-soluble polyhydric alcohol is selected from the group consisting of: diethyleneglycol monobutylether, ethylene glycol monohexyl ether, and a mixture of diethyleneglycol monobutylether and ethylene glycol monohexyl ether.

4 . The composition of claim 1 , wherein the composition comprises one or more coloured materials, wherein the one or more coloured materials is selected from the group consisting of: coloured fibres, coloured beads, coloured particles such as nano-particles, coloured polymers comprising covalently attached dyes, particles having diffraction properties, and combinations thereof.

5 . The composition of claim 1 , wherein the composition has a pH, wherein the pH of the composition is from about 3.0 to about 11.0.

6 . The composition of claim 1 , wherein the composition comprises from about 0.5% to about 2% of the thickening system, by total weight of the composition.

7 . The composition of claim 1 , wherein the thickening polymer is a hydroxyethyl cellulose.

8 . The composition of claim 1 , wherein the composition has a viscosity of from about 50 mPa·s to about 1000 mPa·s, wherein the viscosity is measured at about 25° C.

9 . The composition of claim 1 , wherein the composition comprises from about 1% to about 15% of the aminosilicone polymer (a), by total weight of the composition.

10 . The composition of claim 1 , wherein the composition comprises from about 0.01% to about 5% of the thickening polymer, by total weight of the composition.

11 . The composition of claim 1 , wherein the aminosilicone polymer is a polydimethylsiloxane polymer having graft amino groups.

12 . The composition of claim 1 , wherein the silicone resin is an MQ resin.

13 . The composition of claim 1 , wherein the deposition enhancer conforms to the formula H(OCH 2 CH 2 ) n OH wherein n has an average value of from about 40,000 to about 50,000.

14 . A method for providing a film comprising one or more pigments or one or more coloured materials onto keratin fibres, the method comprising applying the composition of claim 1 onto keratin fibres and allowing the keratin fibres to dry or drying them.

15 . A kit comprising:
the composition of claim 1 ; an applicator.
