Abstract

The invention proposes a bleaching agent-containing washing or cleaning agent that contains a particulate phthalimidoperoxyalkanoic acid and an active substance selected from the group encompassing Zn ions, benzotriazole, nitrate ions, phosphonocarboxylic acids, phosphonic acids, phosphates, polyaspartic acids, fatty amines, surfactants having nitrogen-containing head groups, and mixtures thereof.

Claims

1. A bleaching agent-containing washing or cleaning agent comprising at least one particulate phthalimidoperoxyalkanoic acid and Zn ions.

2. The agent according to claim 1, additionally comprising at least one active substance selected from the group consisting of benzotriazole, nitrate ions, phosphonocarboxylic acids, phosphonic acids, phosphates, polyaspartic acids, fatty amines, and surfactants having nitrogen-containing head groups.

3. The agent according to claim 1, comprising 0.5 wt % to 25 wt % phthalimidoperoxyalkanoic acid.

4. The agent according to claim 1, wherein the phthalimidoperoxyalkanoic acid is 6-phthalimidoperoxyhexanoic acid (PAP).

5. The agent according to claim 1, comprising 0.05 wt % to 4 wt % zinc salt.

6. The agent according to claim 1, comprising 0.2 wt % to 2 wt % zinc salt.

7. The agent according to claim 1, additionally comprising up to 10 wt % phosphonocarboxylic acid.

8. The agent according to claim 1, additionally comprising up to 10 wt % phosphonic acid.

9. The agent according to claim 1, additionally comprising 0.5 wt % to 15 wt % polycarboxylate.

10. The agent according to claim 1, additionally comprising 0.5 wt % to 15 wt % polyacrylate.

11. The agent according to claim 1, additionally comprising a mixture of anionic and nonionic surfactants.

12. The agent according to claim 1, additionally comprising 0.1 wt % to 50 wt % surfactant.

13. The agent according to claim 1, wherein the agent is liquid and has a pH in the range from 2 to 6.

14. The agent according to claim 1, wherein the densities of the phthalimidoperoxyalkanoic acid particles and of the liquid phase of the agent differ from one another by no more than 10%.

15. The agent according to claim 1, wherein the agent is liquid and is made up of at least two subcompositions, held separately from one another, that are present separately from one another in a multi-chamber receptacle, such that a water-containing dispersion of the particulate phthalimidoperoxyalkanoic acid, which comprises Zn ions, is present in one chamber, and one or more other ingredients of the completed washing- or cleaning-agent composition are present in a second chamber or further chambers.

16. The agent according to claim 1, wherein the Zn ions are introduced in the form of one or more water-soluble Zn salts selected from the group consisting of zinc acetate, zinc nitrate and zinc sulfate.

17. The agent according to claim 1, comprising 0.5 wt % to 25 wt % phthalimidoperoxyalkanoic acid, 0.05 wt % to 4 wt % zinc salt, at least one active substance selected from the group consisting of phosphonocarboxylic acids, phosphonic acids and polycarboxylates, and 0.1 wt % to 50 wt % surfactant, wherein the agent is liquid and has a pH in the range from 2 to 6.

18. The agent according to claim 1, comprising 1 wt % to 20 wt % 6-phthalimidoperoxyhexanoic acid, 0.2 wt % to 2 wt % zinc salt, at least one active substance selected from the group consisting of phosphonocarboxylic acids, phosphonic acids and polyacrylates, and 10 wt % to 40 wt % surfactant, wherein the agent is liquid and has a pH in the range from 3 to 5.5 and the densities of the 6-phthalimidoperoxyhexanoic acid particles and of the liquid phase of the agent differ from one another by no more than 10%.

19. A method of making a liquid washing or cleaning agent, comprising preparing a water-containing dispersion of a particulate phthalimidoperoxyalkanoic acid, wherein the water-containing dispersion is comprised of Zn ions.

20. A method of suppressing corrosion phenomena on machine parts in the context of textile laundering in an automatic washing machine using a phthalimidoperoxyalkanoic acid-containing washing agent, said method comprising providing the washing agent with Zn ions.
