Abstract

Liquid, transport- and storage-stable washing or cleaning agents with a flow limit are described which contain a photocatalytic material and a thickening system. The washing or cleaning agents enable textile cleaning, care, finishing, softening and/or conditioning using light with a wavelength in the range from 10-1200 nm. They likewise enable cleaning of hard surfaces using light in the wavelength range from 10-1200 nm.

Claims

1. A liquid washing or cleaning agent, comprising a photocatalytic material and a thickening system.

2. The agent of claim 1, wherein the thickening system comprises:

a) a polyacrylate or derivative thereof;

b) a structure-imparting gum;

c) a cellulose ether derivative;

d) a clay mineral;

or

e) any mixture of a) to d).

3. The agent of claim 2, wherein the thickening system comprises a combination of a polyacrylate or derivative thereof and a structure-imparting gum or a cellulose ether derivative.

4. The agent of claim 1, wherein the photocatalytic material comprises titanium dioxide.

5. The agent of claim 4, wherein the titanium dioxide comprises a carbon-modified titanium dioxide.

6. A method for applying photocatalytic material to textiles, comprising the steps of forming a textile treatment bath comprising the washing or cleaning agent of claim 1 and contacting a textile with the textile treatment bath.

7. A method for textile cleaning, care, finishing, softening, or conditioning, comprising contacting a textile with a textile treatment bath comprising the washing or cleaning agent of claim 1 and exposing the textile to light in the wavelength range from 10-1200 nm.

8. The method of claim 7, further comprising the elimination, deactivation or reduction of microorganisms in the textile using light in the wavelength range from 10-1200 nm.

9. The method of claim 7, further comprising pre-emptive repulsion and inhibition of soiling and stains using light in the wavelength range from 10-1200 nm.

10. The method of claim 7, wherein the photocatalytic material facilitates the removability of colored stains from the textile using light in the wavelength range from 10-1200 nm.

11. The method of claim 7, wherein the photocatalytic material reduces fiber adhesion ability of dirt to the textile using light in the wavelength range from 10-1200 nm.

12. The method of claim 7, wherein the photocatalytic material increases water solubility of dirt on the textile using light in the wavelength range from 10-1200 nm.

13. The method of claim 7, wherein the photocatalytic material prevents the occurrence of fetid odors on the textile using light in the wavelength range from 10-1200 nm.

14. The method of claim 7, wherein the photocatalytic material provides the textile with a self-cleaning ability using light in the wavelength range from 10-1200 nm.

15. The method of claim 7, wherein the photocatalytic material improves the whiteness of the textile using light in the wavelength range from 10-1200 nm.

16. The method of claim 7, further comprising using an automatic washing machine, in which the washing or cleaning agent is added in the postrinsing cycle.
