Abstract

Official abstract text for this publication.

The present invention is on the provision of a composition, method, use of composition to reduce the drying time of keratin fibers, preferably human hair. The composition is aqueous and comprises two or more cationic polymers wherein one of the cationic polymers has a charge density in the range of 2 meq/g to 4 meq/g, and the other cationic polymer has a charge density in the range of 4.1 meq/g to 7 meq/g, and an aminosilicone. A kit of parts is disclosed which comprises the composition and a blow dryer.

First claim

Opening claim text (preview).

What is claimed is: 1. An aqueous cosmetic composition for keratin fibers, comprising: (a) two or more cationic polymers and/or their salts comprising: (a)(i) a first cationic polymer having a charge density in the range of 2 meq/g to 4 meq/g; and (a)(ii) a second cationic polymer having a charge density in the range of 4.1 meq/g to 7 meq/g; (b) amodimethicone present at a concentration range from 0.1% to 5% by weight, calculated to a total of the aqueous cosmetic composition; and (c) from 80% to 95% by weight of water calculated to a total of the aqueous cosmetic composition, wherein the first cationic polymer is present at a concentration range from 0.1% to 5% by weight, calculated to the total of the aqueous cosmetic composition, and is at least one selected from: Polyquaternium 16 and/or its salts having a cationic charge density of 2 meq/g to 4 meq/g; Polyquaternium 7 and/or its salts; and Polyquaternium 37 and/or its salts having a cationic charge density of 2 meq/g to 4 meq/g, wherein the second cationic polymer is present at a concentration range from 0.01% to 5% by weight, calculated to the total of the aqueous cosmetic composition, and is at least one selected from: Polyquaternium 22 and/or its salts; Polyquaternium 16 and/or its salts having a cationic charge density of 4.1 meq/g to 7 meq/g; Polyacrylamidopropyltrimonium chloride; and Polyquaternium 37 and/or its salts having a cationic charge density of 4.1 meq/g to 7 meq/g, and further wherein a weight ratio of the first cationic polymer to the second cationic polymer ranges from 5:1 to 1:1. 2. The aqueous cosmetic composition according to claim 1 , wherein the second cationic polymer is polyacrylamidopropyltrimonium chloride. 3. The aqueous cosmetic composition according to claim 1 , wherein the first cationic polymer is Polyquaternium 16. 4. The aqueous cosmetic composition according to claim 1 , further comprising: one or more ingredients selected from the group consisting of fragrances, preservatives, antioxidants, essential oils, vegetable oils, organic solvents, ceramides, ubiquinones, UV filtering compounds, amino acids, vitamins, and plant extracts. 5. The aqueous cosmetic composition according to claim 1 , further comprising: a hair direct dye. 6. A method for reducing the drying time of hair, the method comprising: applying the aqueous cosmetic composition according to claim 1 onto hair; washing the hair having the aqueous cosmetic composition applied thereto; and drying the hair with a hair drier. 7. The method according to claim 6 , wherein the hair drier is operable at temperatures from 40° C. to 90° C. 8. A kit comprising: the aqueous cosmetic composition according to claim 1 , wherein the components (a)(i), (a)(ii), and (b) are provided together as one component of the kit or separate as separate components of the kit; and at least one blow drier. 9. The aqueous cosmetic composition according to claim 1 , wherein the weight ratio of the first cationic polymer to the second cationic polymer ranges from 3:1 to 1:1.
