Abstract

The invention relates to a method for mending split ends of hair comprising contacting the hair with split ends with a composition comprising at least cationic polygalactomannan containing non-ionic hydroxyalkyl substituents and having a Brookfield RVT viscosity at 25° C. and 20 rpm greater than 700 mPa·s, at a concentration of 1 pbw in water, for instance comprised between 700 and 1,200 mPa·s.

Claims (15)

1 . A personal care composition comprising from 0.01 to 10 pbw of at least one cationic polygalactomannan having non-ionic hydroxyalkyl substituents, based on a total weight of the personal care composition, wherein the cationic galactomannan having non-ionic hydroxyalkyl substituents has a Brookfield RVT viscosity at 25° C. and 20 rpm of greater than 700 mPa·s, at a concentration of 1 pbw in water.

2 . The personal care composition according to claim 1 , wherein the Brookfield RVT viscosity at 25° C. and 20 rpm is between 700 and 1,200 mPa·s, at a concentration of 1 pbw in water.

3 . The personal care composition according to claim 1 , wherein the Brookfield RVT viscosity at 25° C. and 20 rpm is between 700 and 950 mPa·s, at a concentration of 1 pbw in water.

4 . The personal care composition according to claim 1 , wherein the Brookfield RVT viscosity at 25° C. and 20 rpm is between 750 and 950 mPa·s, at a concentration of 1 pbw in water.

5 . The personal care composition according to claim 1 , wherein the Brookfield RVT viscosity at 25° C. and 20 rpm is between 750 and 900 mPa·s, at a concentration of 1 pbw in water.

6 . The personal care composition according to claim 1 , wherein the Brookfield RVT viscosity at 25° C. and 20 rpm is between 750 and 850 mPa·s, at a concentration of 1 pbw in water.

7 . The personal care composition according to claim 1 , wherein said polygalactomannan is guar.

8 . The personal care composition according to claim 1 , wherein the cationic polygalactomannan is a cationic guar having hydroxypropyl substituents.

9 . The personal care composition according to claim 1 , wherein the cationic polygalactomannan is a hydroxypropyl guar hydroxypropyltrimonium chloride.

10 . The personal care composition according to claim 1 , wherein the personal care composition is a hair care composition.

11 . The personal care composition according to claim 1 , wherein the personal care composition is a leave-on composition.

12 . The personal care composition according to claim 1 , wherein the personal care composition is a rinse-off composition.

13 . The personal care composition according to claim 1 comprising from 0.05 to 5 pbw of the cationic polygalactomannan having non-ionic hydroxyalkyl substituents relative to the total weight of the composition.

14 . The personal care composition according to claim 1 comprising from 0.1 to 2 pbw of the cationic polygalactomannan having non-ionic hydroxyalkyl substituents relative to the total weight of the composition.

15 . The personal care composition according to claim 1 , wherein the personal care composition is a hair care composition to mend split ends.
