Abstract

The present invention relates to a composition and method for treating a textile under industrial and institutional fabric care conditions to impart softness with reduced yellowing. More particularly, the present invention relates to a solid fabric conditioning composition and a method for treating a textile with a solid fabric conditioning composition.

Claims

1. A solid fabric softening composition comprising:

(a) from about 5 wt. % to about 10 wt. % of one or more surfactants, wherein one of the surfactants comprises a nonionic ethoxylated surfactant;

(b) from about 25 wt. % to about 60 wt. % of one or more solidification agents, wherein one of the solidification agents is urea; and

(c) from about 30 wt. % to about 55 wt. % of one or more softening agents, wherein one of the softening agents comprises a quaternary ammonium compound.

2. The composition of claim 1 wherein the surfactants further comprise quaternary surfactants, or mixtures thereof.

3. The composition of claim 1 wherein the solidification agent further comprises about 5 wt. % to about 20 wt. % polyethylene glycol with a molecular weight of 4000 (PEG-4000) or 8000 (PEG-8000).

4. The composition of claim 1 wherein the solidification agent is about 19 wt. % to about 30 wt. % urea.

5. The composition of claim 1 wherein the softening agent is about 30 wt. % to about 45 wt. % quaternary ammonium component, about 5 wt. % to about 10 wt. % polydimethyl siloxane, or mixtures thereof.

6. The composition of claim 5 wherein the ratio of quaternary ammonium component to polydimethyl siloxane is between about 9:

1 to about 11;

1.

7. The composition of claim 1 wherein the composition comprises at least one of amidoamine quaternary ammonium, ester quaternary ammonium, dimethyl ditallowamine, imidazoline quaternary amine and mixtures thereof.

8. The composition of claim 1 wherein the solid is in the form of a block or a bar.

9. The composition of claim 1 wherein pH of the composition is in the range of about 2 to about 8.

10. A method of softening fabrics, comprising:

(a) washing the fabrics in a detergent with a pH range of about 7 to about 14;

(b) contacting the fabrics with the composition of claim 1; and

,

(c) drying the fabrics.

15. The method of claim 1 wherein the softening agent is about 30 wt. % to about 45 wt. % quaternary ammonium component, about 5 wt. % to about 10 wt. % polydimethyl siloxane, or mixtures thereof.

16. The method of claim 15 wherein the ratio of quaternary ammonium component to polydimethyl siloxane is between about 9:

1 to about 11;

1.

17. The method of claim 1 wherein the composition comprises at least one of amidoamine quaternary ammonium, ester quaternary ammonium, dimethyl ditallowamine, imidazoline quaternary amine and mixtures thereof.

18. The method of claim 1 wherein the solid is in the form of a block or a bar.

19. The method of claim 1 wherein pH of the composition is in the range of about 2 to about 8.

11. A method of softening fabrics, comprising:

(a) washing the fabrics in a detergent with a pH range of about 7 to about 14;

(b) contacting the fabrics in a wash cycle or final rinse with the treatment dilution, wherein the composition comprises;

i. from about 5 wt. % to about 10 wt. % of one or more surfactants, wherein one of the surfactants comprises a nonionic ethoxylated surfactant;

ii. from about 25 wt. % to about 60 wt. % of one or more solidification agents, wherein one of the solidification agents is urea;

iii. from about 30 wt. % to about 55 wt. % of one or more softening agents, wherein one of the softening agents comprises a quaternary ammonium compound; and

(c) drying the fabrics.

12. The method of claim 11 wherein the surfactants further comprise quaternary surfactants, or mixtures thereof.

13. The method of claim 11 wherein the solidification agent further comprises about 5 wt. % to about 20 wt. % polyethylene glycol with a molecular weight of 4000 (PEG-4000) or 8000 (PEG-8000).

14. The method of claim 11 wherein the solidification agent is about 19 wt. % to about 30 wt. % urea.
