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 consisting of:
a first fabric conditioning composition comprising from about 0.05 wt-% to about 40 wt-% of an amino-functionalized silicone softening agent and from about 2 wt-% to about 55 wt-% of a softening agent selected from the group consisting of an amidoamine quaternary ammonium, ester quaternary ammonium, dimethyl ditallowamine, imidozoline quaternary amine and mixtures thereof; and
a second, separately dosed, softening booster composition comprising from about 0.1 wt-% to about 40 wt-% of a quaternary ammonium compound.

2. The system of claim 1 , wherein the softening booster composition is a dialkyl quaternary compound.

3. The system of claim 2 , wherein the softening booster composition is di(hydrogenated tallowalkyl)dimethyl ammonium chloride.

4. The system of claim 1 , wherein the fabric conditioning composition further comprises a nonionic ethoxylated surfactant, quaternary surfactant, or mixture 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 selected from the group consisting of 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 and combinations of the same.

7. The system of claim 1 , wherein the softening agent is amidoamine quaternary ammonium.

8. The system of claim 1 , wherein the first fabric softening composition comprises the ester quaternary ammonium compound in the amount of about 2 wt-% to about 55 wt-% and the second softening booster composition comprises the quaternary ammonium compound in an amount from about 5 wt-% to about 40 wt-%.

9. The system of claim 1 , wherein the percent actives ratio of the first fabric softening composition to the second softening booster composition is between about 2:1 to about 1:2.

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

11. A conditioning and softening fabric system consisting of:
a first fabric conditioning composition comprising from about 0.05 wt-% to about 40 wt-% of an amino-functionalized silicone softening agent and from about 2 wt-% to about 55 wt-% of a softening agent selected from the group consisting of an amidoamine quaternary ammonium, ester quaternary ammonium, dimethyl ditallowamine, imidozoline quaternary amine and mixtures thereof; and
a second, separately dosed, softening booster composition comprising in a use solution from about 5 wt-% to about 40 wt-% of a quaternary ammonium compound.

12. The system of claim 11 , wherein the softening booster composition is a dialkyl quaternary compound.

13. The system of claim 12 , wherein the softening booster composition is di(hydrogenated tallowalkyl)dimethyl ammonium chloride.

14. The system of claim 11 , wherein the fabric conditioning composition further comprises a nonionic ethoxylated surfactant, quaternary surfactant, or mixture thereof.

15. The system of claim 11 , wherein the first composition and/or the second composition are liquids, powders and/or solids.

16. The system of claim 11 , wherein the first and/or second composition further comprises at least one additional functional ingredient selected from the group consisting of 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 and combinations of the same.

17. The system of claim 11 , wherein the softening agent is ester quaternary ammonium.

18. The system of claim 11 , wherein the fabric softening composition comprises the ester quaternary ammonium compound in the amount of about 2 wt-% to about 55 wt-% and the second softening booster composition comprises the quaternary ammonium compound in an amount from about 5 wt-% to about 30 wt-%.

19. The system of claim 11 , wherein the percent actives ratio of the fabric softening composition to the softening booster composition is between about 2:1 to about 1:2.

20. The system of claim 11 , wherein the fabric softening composition has a use solution 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.
