Abstract

The present invention relates to a non-cellulosic polysaccharide derivative: i) having a mean average molecular weight (Mw) from about 100,000 g/mol, preferably from about 150,000 g/mol and more preferably from about 200,000 g/mole to about 2,000,000 g/mol, preferably to about 1,800,000 g/mol and more preferably to about 1,400,000 g/mole; and ii) containing at least one cationic group, with a cationic degree of substitution (DS cat. ) extraction , from about 0.20 to about 0.30.

Claims (33)

1. A personal care composition comprising 0.2 wt. % to 0.9 wt. % of at least one guar derivative, the guar derivative comprising:

i) a mean average molecular weight (Mw) from about 250,000 g/mol to about 600,000 g/mol; and

ii) at least one hydroxypropyltrimethylammonium group, with a cationic degree of substitution (DS cat ) extraction , from about 0.20 to about 0.30,

wherein the weight percentage of the at least one guar derivative is based on the total weight of the personal care composition, and the personal care composition reduces wet combing work by at least 50% relative to compositions that do not contain the guar derivative.

2. The personal care composition according to claim 1 , wherein the mean average molecular weight is from about 300,000 g/mol to about 600,000 g/mol.

3. The personal care composition according to claim 1 , wherein the (DS cat ) extraction is from about 0.20 to about 0.25.

4. The personal care composition according to claim 1 , wherein the (DS cat ) extraction is from about 0.25 to about 0.30.

5. The personal care composition according to claim 1 comprising 0.4 wt. % to 0.9 wt. % of the at least one guar derivative.

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

7. A shampoo composition comprising 0.2 wt. % to 0.9 wt. % of at least one guar derivative, the guar derivative comprising:

i) a mean average molecular weight (Mw) from about 250,000 g/mol to about 600,000 g/mol; and

ii) at least one hydroxypropyltrimethylammonium group, with a cationic degree of substitution (DS cat ) extraction , from about 0.20 to about 0.30,

wherein the weight percentage of the at least one guar derivative is based on the total weight of the shampoo composition, and the shampoo composition reduces wet combing work by at least 50% relative to compositions that do not contain the guar derivative.

8. The shampoo composition according to claim 7 , further comprising silicone.

9. The shampoo composition according to claim 8 , further comprising an antidandruff agent.

10. The shampoo composition according to claim 7 comprising 0.4 wt. % to 0.9 wt. % of the at least one guar derivative.

11. A method for

i) providing conditioning effects to the hair; and/or

ii) providing care to hair and/or scalp; and/or

iii) providing a nice dry hair appearance;

wherein said method comprises treating the hair in need thereof with the personal care composition of claim 1 .

12. The method according to claim 11 , wherein the hair is damaged hair.

13. A method for

i) providing conditioning effects to the hair; and/or

ii) providing care to hair and/or scalp; and/or

iii) providing a nice dry hair appearance;

wherein said method comprises treating the hair with the hair composition of claim 6 .

14. The method according to claim 13 , wherein the hair is damaged hair.

15. A method of treating hair, the method comprising treating the hair with a hair composition, wherein said hair composition comprises 0.2 wt. % to 0.9 wt. % of at least one guar derivative, the guar derivative comprising:

i) a mean average molecular weight (Mw) from about 250,000 g/mol to about 600,000 g/mol; and

ii) at least one hydroxypropyltrimethylammonium group, with a cationic degree of substitution, (DS cat ) extraction , from about 0.20 to about 0.30,

wherein the weight percentage of the at least one guar derivative is based on the total weight of the hair composition, and the hair composition reduces wet combing work by at least 50% relative to compositions that do not contain the guar derivative.

16. The method of claim 15 , wherein the hair composition comprises 0.4 wt. % to 0.9 wt. % of the at least one guar derivative.
