Abstract

Liquid aqueous washing agent containing nonionic surfactant, esterquat, and phthaloylaminoperoxycaproic acid and methods of disinfecting textiles therewith.

Claims (20)

1. A liquid aqueous acid washing agent comprising an esterquat, phthaloylaminoperoxycaproic acid, and 2.5 wt. % to 30 wt. % of a nonionic surfactant wherein the washing agent is free of anionic surfactants.

2. The agent of claim 1 , wherein in undiluted form it has a pH of 3 to 5.

3. The agent of claim 2 , wherein in undiluted form it has a pH of 3.8 to 4.7.

4. The agent of claim 1 , comprising 6 wt. % to 23 wt. % of a nonionic surfactant.

5. The agent of claim 1 , wherein the nonionic surfactant comprises one or more ethoxylated C 8-18 (3EO–12EO) alcohols.

6. The agent of claim 1 , comprising 2 wt. % to 25 wt. % of the esterquat.

7. The agent of claim 6 , comprising 6 wt. % to 15 wt. % of the esterquat.

8. The agent of claim 1 , comprising 1 wt. % to 20 wt. % phthaloylaminoperoxycaproic acid.

9. The agent of claim 8 , comprising 4 wt. % to 10 wt. % phthaloylaminoperoxycaproic acid.

10. The agent of claim 1 , further comprising one or more polymeric polycarboxylic acids or their corresponding polycarboxylates.

11. The agent of claim 1 , further comprising at least one color transfer inhibitor.

12. The agent of claim 11 , wherein the color transfer inhibitor is selected from the group consisting of polymers of vinyl imidazole, vinyl pyrrolidone, and copolymers thereof.

13. The agent of claim 1 , further comprising at least one corrosion inhibitor.

14. A process for disinfectant washing of a textile, comprising the steps of contacting a textile in need of disinfecting with the composition of claim 1 at a temperature below 60° C. for a time sufficient to effect said disinfecting.

15. The process of claim 14 , wherein the temperature is below 40° C.

16. The process of claim 15 , wherein the temperature is 20° C. to 30° C.

17. The process of claim 14 , wherein the textile comprises wool, silk, suede, synthetic suede, down, fleece, stuffing, and/or functional textiles based on textured microfibers or mixtures of cellulose fibers, regenerated cellulose fibers and/or synthetic fibers.

18. The process of claim 17 , wherein the functional textiles contain mixtures of optionally elastic polyurethane threads, polyester fibers, polyamide fibers and/or polyacrylic fibers with wool, silk, and/or cotton.

19. The process according of claim 14 , wherein the textiles are fitted with microporous or hydrophilic membranes.

20. The process of claims 14 , wherein the textiles have outer materials with a hydrophobic impregnation.
