Abstract

Method for treating a textile under industrial and institutional fabric care conditions to impart softness within a single wash and/or rinse cycle are disclosed. More particularly, the present invention relates to a combination of a liquid or solid fabric conditioning composition and a softening booster for treating a textile to impart softness within a single wash and/or rinse cycle. Compositions employed therein are further disclosed.

First claim

What is claimed is:

1. A conditioning and softening fabric system comprising:
a first fabric conditioning composition comprising an amino-functionalized silicone softening agent; and
a second softening booster composition comprising an ester quaternary ammonium compound and an alkylated quaternary ammonium compound;
wherein the fabric conditioning composition and the softening booster composition are dosed separately.

2. The system of claim 1 , wherein the alkylated quaternary ammonium compound is a dialkyl quaternary compound.

3. The system of claim 2 , wherein the alkylated quaternary ammonium compound is di(hydrogenated tallowalkyl)dimethyl ammonium chloride.

4. The system of claim 1 , wherein the fabric conditioning composition further comprises a surfactant comprising nonionic ethoxylated surfactants, quaternary surfactants, or mixtures thereof.

5. The system of claim 1 , wherein the first composition and/or the second composition are liquids, powders and/or solids.

6. The system of claim 1 , wherein the first and/or second composition further comprises at least one additional functional ingredient comprising fragrances and/or dyes, anti-static agents, fiber protection agents, anti-wrinkling agents, soil release agents, optical brighteners, UV protection agents, anti- pilling agents, water repellency agents, disinfecting and/or sanitizing agents, scouring agents, insect repellants, bleaching agents, solubility modifiers, rheology modifiers or thickeners, buffers, solvents, dye scavengers, molecular chelants, sequestering agents, or combinations of the same.

7. The system of claim 1 , wherein the first composition further comprises a softening agent comprising an amidoamine quaternary ammonium, ester quaternary ammonium, dimethyl ditallowamine, imidazoline quaternary amine, or a combination thereof.

8. The system of claim 1 , wherein a use solution on an actives % basis comprises from about 0.1% to about 40% of the softening booster composition.

9. The system of claim 1 , wherein the fabric conditioning composition has a use pH in the range of about 2 to about 8 and the softening booster compositions has a use solution pH in the range of about 2 to about 10.

10. A method of conditioning and 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 a first fabric conditioning composition comprising an amino-functionalized silicone softening agent;
(c) contacting the fabrics with a second softening booster composition comprising an ester quaternary ammonium compound and an alkylated quaternary ammonium compound; and
(d) drying the fabrics;
wherein the fabric conditioning composition and the softening booster composition are dosed separately.

11. The method of claim 10 , wherein the alkylated quaternary compound is a dialkyl quaternary compound.

12. The method of claim 11 , wherein the alkylated quaternary compound is di(hydrogenated tallowalkyl)dimethyl ammonium chloride.

13. The method of claim 10 , wherein the fabric conditioning composition further comprises a surfactant comprising nonionic ethoxylated surfactants, quaternary surfactants, or a combination thereof.

14. The method of claim 10 , wherein the first composition and/or the second composition are liquids, powders and/or solids.

15. The method of claim 10 , wherein the first and/or second composition further comprises at least one additional functional ingredient comprising fragrances and/or dyes, anti-static agents, fiber protection agents, anti-wrinkling agents, soil release agents, optical brighteners, UV protection agents, anti-pilling agents, water repellency agents, disinfecting and/or sanitizing agents, scouring agents, insect repellants, bleaching agents, solubility modifiers, rheology modifiers or thickeners, buffers, solvents, dye scavengers, molecular chelants, sequestering agents, or a combination thereof.
