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 for washing fabrics comprising:
a first fabric conditioning composition comprising one or more softening agents, wherein at least one of the softening agents is an amidoamine quaternary ammonium compound, wherein the fabric conditioning composition is free of silicone;
a second softening booster composition comprising an additional amidoamine quaternary ammonium compound; and
a souring agent;
wherein the fabric conditioning composition and the softening booster composition are dosed separately.

2. The system of claim 1 , wherein the amidoamine quaternary ammonium compound comprises a diamidoamine quaternary ammonium compound.

3. The system of claim 1 , wherein the amidoamine quaternary ammonium compound is a methyl-bis(tallow amidoethyl)-2-hydroxyethyl ammonium methyl sulfate, a methyl bis(oleylamidoethyl)-2-hydroxyethyl ammonium methyl sulfate, a methyl bis (hydr.tallowamidoethyl)-2-hydroxyethyl ammonium methyl sulfate, or a combination thereof.

4. The system of claim 1 , wherein the amidoamine quaternary ammonium compound is present in the amount of from about 2 wt-% to about 55 wt-% of the fabric conditioning composition.

5. The system of claim 1 , wherein the fabric conditioning composition has a use pH in the range of about 3 and about 8.

6. 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 the system of claim 1 ; and
(c) drying the fabrics.

7. The method of claim 6 , wherein the amidoamine quaternary ammonium compound comprises a diamidoamine quaternary ammonium compound.

8. The method of claim 6 , wherein the amidoamine quaternary ammonium compound is a methyl-bis(tallow amidoethyl)-2-hydroxyethyl ammonium methyl sulfate, a methyl bis(oleylamidoethyl)-2-hydroxyethyl ammonium methyl sulfate, a methyl bis (hydr.tallowamidoethyl)-2-hydroxyethyl ammonium methyl sulfate, or a combination thereof.

9. The method of claim 6 , wherein the fabric conditioning composition of the system has a use pH in the range of about 3 and about 8.

10. The method of claim 6 , wherein the fabric conditioning composition of the system further comprises a surfactant comprising nonionic ethoxylated surfactants, quaternary surfactants, or a combination thereof.

11. The method of claim 6 , wherein the fabric conditioning composition of the system comprises liquids, powders and/or solids.

12. The method of claim 6 , wherein the souring agent of the system comprises liquids.

13. The method of claim 6 , wherein the system 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.
