Abstract

A laundry additive composition comprising a) at least one oxylated material chosen from polyoxyalkylene, a polyoxyalkylene fatty acid ester, and a polyoxyalkylene fatty alcohol ether; b) a polyol; c) a coloring agent; and d) at least one additive chosen from fragrance and a fabric treatment material. The composition can deliver the additive to clothing during washing or rinsing of the clothes, such as to impart a fragrance to clothing.

First claim

What is claimed is:

1. A laundry additive composition, comprising:
a) polyethylene glycol, a polyoxyalkylene polymer, and at least one oxylated material chosen from a polyoxyalkylene fatty acid ester, and a polyoxyalkylene fatty alcohol ether;
b) a polyol;
c) a coloring agent; and
d) at least one additive chosen from fragrance and a fabric treatment material.

2. The composition of claim 1 , wherein the polyethylene glycol, the polyoxyalkylene polymer, and the at least one oxylated material are present in the composition in an amount of 30 to 90% by weight of the composition.

3. The composition of claim 1 , wherein the polyalkylene polymer has a formula: H—(C 2 H 4 O) x —(CH(CH 3 )CH 2 O) y —(C 2 H 4 O) z —OH; wherein x is from 50 to 300; y is from 20 to 100, and z is from 10 to 200;
wherein the polyethylene glycol fatty acid ester has a formula: (C 2 H 4 O) q —C(O)O—(CH 2 ) r —CH 3 ; wherein q is from 20 to 200, and r is from 10 to 30; and
wherein the polyethylene glycol fatty alcohol ether has a formula: HO—(C 2 H 4 O) s —(CH 2 ) t —CH 3 ; wherein s is from 30 to 250, and t is from 10 to 30.

4. The composition of claim 3 , wherein the polyethylene glycol is present in the composition in an amount of 30 to 90% by weight of the composition.

5. The composition of claim 3 , wherein the polyalkylene polymer is present in the composition in an amount of 15 to 40% by weight of the composition.

6. The composition of claim 3 , wherein the polyethylene glycol fatty acid ester is present in the composition in an amount of 1 to 10% by weight of the composition.

7. The composition of claim 3 , wherein the polyethylene glycol fatty alcohol ether is present in the composition in an amount of 0.1 to 10% by weight of the composition.

8. The composition of claim 3 , wherein the polyethylene glycol has a weight average molecular weight of 2,000 to 10,000.

9. The composition of claim 1 , wherein the polyol is selected from the group consisting of glycerin and sorbitol.

10. The composition of claim 1 , wherein the polyol is present in an amount of 0.1 to 10% by weight of the composition.

11. The composition of claim 1 , wherein the additive is fragrance and is present in an amount of from 0.1 to 10% by weight of the composition.

12. The composition of claim 1 , wherein the additive is the fabric treatment material and is selected from the group consisting of a fabric conditioning agent, anti-static agent, an alkyl trimethyl ammonium compound, an amidopropyl trimethyl ammonium compound, a fatty acid amide, tetraethylenepentamine, amino functional silane, and cetyl trimethylammonium chloride and combinations thereof.

13. The composition of claim 1 , wherein the coloring agent is a combination of dye and pigment and is present in an amount of 0.01 to 5% by weight of the composition.

14. The composition of claim 1 , further comprising clay, and wherein the clay is present in an amount of 0.1 to 50% by weight of the composition.

15. The composition of claim 1 , further comprising an anti-caking agent, wherein the anti-caking agent is present in the composition in an amount of from 0.1 to 1% by weight of the composition.

16. The composition of claim 1 , wherein the composition is in the form of a powder, pellet, tablet, pastille or extrudate.

17. The composition of claim 1 , wherein the composition comprises:
a) 35 to 37 weight % of a polyethylene glycol;
b) 20 to 23 weight % of a polyalkylene polymer of formula: H—(C 2 H 4 O) x —(CH(CH 3 )CH 2 O) y —(C 2 H 4 O) z —OH; wherein x is from 50 to 300; y is from 20 to 100, and z is from 10 to 20;
c) 10 to 12 weight % of a polyethylene glycol fatty acid ester of formula: (C 2 H 4 O) q —C(O)O—(CH 2 ) r —CH 3 ; wherein q is from 20 to 200, and r is from 10 to 30;
d) 3 to 5 weight % a polyethylene glycol fatty alcohol ether of formula: HO—(C 2 H 4 O) s —(CH 2 ) t —CH 3 ; wherein s is from 30 to 250, and t is from 10 to 30;
e) 2 to 4 weight % free fragrance;
f) 3 to 5 weight % encapsulated fragrance; and
g) 0.1 to 1 weight % glycerin.

18. The composition of claim 17 , wherein the polyethylene glycol has a weight average molecular weight of 2,500 to 4,000, and wherein the coloring agent comprises from about 0.001 to about 0.2% by weight of polymeric dye and from about 0.5 to about 2% by weight of titanium dioxide.

19. A method for imparting fragrance, softness or antistatic properties to clothes, comprising washing the clothes in the presence of a composition according to claim 1 .
