Abstract

The present invention relates to a composition, in particular, a fabric conditioning composition, comprising at least a quaternary ammonium compound, a cationic polysaccharide and a nonionic polysaccharide. In particular, the quaternary ammonium compound is a biodegradable quaternary ammonium compound. The composition has excellent softening performance and improved perfume longevity.

Claims (36)

1. A composition comprising: (a) from 3 to 8 wt. % of a quaternary ammonium compound; (b) from 0.2 to 5 wt. % of a cationic polysaccharide; and (c) from 0.2 to 5 wt. % of a nonionic polysaccharide;

wherein the quaternary ammonium compound has the general formula:

[N + ((CH 2 ) n -T-R 8 ) 2 (R 8 )(R 9 )] y X −

wherein:

R 9 group is independently selected from C 1 -C 4 alkyl or hydroxylalkyl group;

R 8 group is independently selected from C 1 -C 30 alkyl or alkenyl group;

T is C(═O)—O—;

n is an integer from 0 to 5;

y is the valence of X; and

X is an anion, and

the weight percentages are based on a total weight of the composition.

2. The composition according to claim 1 , wherein the quaternary ammonium compound has the general formula:

[N + (C 2 H 4 —OOCR 10 ) 2 (CH 3 )(C 2 H 4 —OH)](CH 3 ) z SO 4 −

wherein R 10 is a C 12 -C 20 alkyl group; and

z is an integer from 1 to 3.

3. The composition according to claim 1 , wherein the quaternary ammonium compound is dimethylbis[2-[(1-oxooctadecyl)oxy]ethyl]ammonium chloride.

4. The composition according to claim 1 , wherein the quaternary ammonium compound is selected from the group consisting of:

TET: Di(tallowcarboxyethyl)hydroxyethyl methyl ammonium methylsulfate;

TEO: Di(oleocarboxyethyl)hydroxyethyl methyl ammonium methylsulfate;

TES: Distearyl hydroxyethyl methyl ammonium methylsulfate;

TENT: Di(hydrogenated tallow-carboxyethyl)hydroxyethyl methyl ammonium methylsulfate; and

TEP: Di(palmiticcarboxyethyl)hydroxyethyl methyl ammonium methylsulfate.

5. The composition according to claim 1 , wherein the cationic polysaccharide is a cationic guar.

6. The composition according to claim 1 , wherein the nonionic polysaccharide is a nonionic guar.

7. The composition according to claim 1 , wherein the cationic polysaccharide has an average molecular weight of between 100,000 daltons and 1,500,000 daltons.

8. The composition according to claim 1 , wherein the weight ratio of the quaternary ammonium compound to the total weight of the cationic polysaccharide and the nonionic polysaccharide is between 100:1 and 2:1.

9. The composition according claim 1 , wherein the weight ratio of the quaternary ammonium compound to the total weight of the cationic polysaccharide and the nonionic polysaccharide is between 30:1 and 5:1.

10. The composition according to claim 1 further comprising a fragrance material or perfume.

11. The composition according to claim 1 further comprising an inorganic salt.

12. A recipient containing the composition according to claim 1 .

13. The recipient according to claim 12 , wherein the recipient has an opening and a cover for closing the opening.

14. The composition according to claim 1 , wherein the composition comprises 0.2 to 2 wt. % of the cationic polysaccharide.

15. The composition according to claim 1 , wherein the composition comprises 0.2 to 2 wt. % of the nonionic polysaccharide.

16. A process for making the composition according to claim 1 , wherein the process comprises:

mixing the quaternary ammonium compound with an aqueous dispersion, the aqueous dispersion comprising at least a mixture of the cationic polysaccharide and the nonionic polysaccharide, wherein the aqueous dispersion has a pH value in the range of 3.5 to 5.

17. The composition according to claim 1 further comprising a silicone compound.
