Abstract

The present invention relates to a washing additive article comprising a water-insoluble textile substrate, and to a washing additive composition comprising a bleaching agent present in solidified form on the substrate. In order to fix the bleaching agent particles, the washing additive composition comprises a film-forming polymer.

Claims

1. An auxiliary washing agent article comprising:

a. a water-insoluble textile substrate; and

b. a bleach-containing auxiliary washing agent composition solidified on said substrate; and

wherein said bleach-containing auxiliary washing agent composition comprises a film-forming polymer.

2. The auxiliary washing agent article of claim 1, wherein said textile substrate is a woven fabric or a non-woven fabric.

3. The auxiliary washing agent article of claim 1, wherein said bleach-containing auxiliary washing agent composition contains a phthalimidoperoxoalkanoic acid.

4. The auxiliary washing agent article of claim 3, wherein said phthalimidoperoxoalkanoic acid is 6-phthalimidoperoxohexanoic acid.

5. The auxiliary washing agent article of claim 1, wherein said film forming polymer is selected from the group consisting of polyvinyl alcohol, high molecular-weight polyethylene glycol, polyvinylpyrrolidone, starch ethers, cellulose ethers, polyacrylates, and mixtures thereof.

6. The auxiliary washing agent article of claim 1, wherein said bleach-containing auxiliary washing agent composition further contains a plasticizer for the film-forming polymer.

7. The auxiliary washing agent article of claim 6, wherein said plasticizer is selected from the group consisting of 1,2-propanediol, 1,3-propanediol, ethylene glycol, diethylene glycol, 2,3-butanediol, triethyl citrate, paraffin oil, and mixtures thereof.

8. The auxiliary washing agent article of claim 1, wherein said bleach-containing auxiliary washing agent composition contains a further ingredient selected from the group consisting of surfactants, optical brighteners, bleach activators, bleach catalysts, enzymes, hydrocarbons, builders, perfumes, corrosion inhibitors, and mixtures thereof.

9. The auxiliary washing agent article of claim 1 further including an additional composition solidified on said substrate.

10. The auxiliary washing agent article of claim 9, wherein said additional composition is a different color than said bleach-containing auxiliary washing agent composition.

11. The auxiliary washing agent article of claim 9, wherein said bleach-containing auxiliary washing agent composition and said additional composition are adjacent to one another on said substrate.

12. The auxiliary washing agent article of claim 9, wherein said bleach-containing auxiliary washing agent composition and said additional composition are at least partially overlapping one another on said substrate.

13. Use of the auxiliary washing agent article of claim 1 for the pre-treatment or washing of laundry.

14. A method pre-treatment or washing of laundry by machine or hand using an auxiliary washing agent article, said method comprising the step of adding the auxiliary washing agent article of claim 1 to a laundry machine.

15. A method for manufacturing the auxiliary washing agent article of claim 1, said method comprising the steps of:

a. providing said textile substrate;

b. providing said bleach-containing auxiliary washing agent composition in a liquid and free-flowing form;

c. applying said bleach-containing auxiliary washing agent composition onto at least one area of said textile substrate; and

d. drying said composition onto said substrate.

16. A method for manufacturing the auxiliary washing agent article of claim 1, said method comprising the steps of:

a. providing said textile substrate;

b. providing said bleach-containing auxiliary washing agent composition in a heated melt form;

c. applying said bleach-containing auxiliary washing agent composition onto at least one area of said textile substrate; and

d. allowing said composition to cool into a solid on said substrate.
