Abstract

A hair conditioner formulation is provided, comprising: a dermatologically acceptable vehicle; and a conditioning polymer, wherein the conditioning polymer is a dextran polymer crosslinked with a dextran crosslinking agent of formula (I) wherein X is a halogen; wherein each R 1 is independently selected from a substituted or unsubstituted C 1-6 alkyl group; wherein each R 2 is independently selected from the group consisting of a C 1-6 alkanediyl group; wherein Y is a divalent bridging group.

Claims (16)

1 . A hair conditioner formulation, comprising:

a dermatologically acceptable vehicle; and

a conditioning polymer, wherein the conditioning polymer is a dextran polymer crosslinked with a dextran crosslinking agent of formula (I)

wherein X is a halogen; wherein each R 1 is independently selected from a substituted or unsubstituted C 1-6 alkyl group; wherein each R 2 is independently selected from the group consisting of a C 1-6 alkanediyl group; wherein Y is a divalent bridging group.

2 . The hair conditioner formulation of claim 1 , wherein the hair conditioner formulation contains less than 0.01 wt %, based on weight of the hair conditioner formulation, of a dermatologically acceptable oil.

3 . The hair conditioner formulation of claim 2 , wherein the hair conditioner formulation contains less than 0.1 wt %, based on weight of the hair conditioner formulation, of silicon containing molecules.

4 . The hair conditioner formulation of claim 3 , wherein the hair conditioner formulation is selected from the group consisting of a rinse off conditioner formulation and a leave in conditioner formulation.

5 . The hair conditioner formulation of claim 4 , wherein the hair conditioner formulation is a rinse off conditioner formulation.

6 . The hair conditioner formulation of claim 5 , wherein the cationic dextran polymer has a Kjeldahl nitrogen content corrected for ash and volatiles, TKN, of 0.5 to 5.0 wt %.

7 . The hair conditioner formulation of claim 6 , wherein the dextran crosslinking agent of formula (I) is selected from the group consisting of

and mixtures thereof.

8 . The hair conditioner formulation of claim 7 , further comprising a thickener.

9 . The hair conditioner formulation of claim 8 , further comprising a preservative.

10 . A method of conditioning mammalian hair, comprising:

selecting a hair conditioner formulation according to claim 1 ; and

applying the hair conditioner formulation to mammalian hair.
