Abstract

The application describes a water-soluble packaging having at least two chambers and containing a first liquid detergent or cleaning agent with a low content of water, a second liquid detergent or cleaning agent with a low content of water and a water-soluble wrapping, the first liquid detergent or cleaning agent with a low content of water containing an optical brightener and the second liquid detergent or cleaning agent with a low content of water containing a color transfer inhibitor.

Claims

1. A water-soluble packaging having at least two chambers and containing a first liquid detergent or cleaning agent with a low content of water, a second liquid detergent or cleaning agent with a low content of water and a water-soluble wrapping, said first liquid detergent or cleaning agent with a low content of water containing an optical brightener and said second liquid detergent or cleaning agent with a low content of water containing a color transfer inhibitor, wherein low content of water is less than 15% by weight in each case in relation to the total first and/or second liquid detergent or cleaning agent;

and wherein the first liquid detergent or cleaning agent is free from color transfer inhibitors and the second liquid detergent or cleaning agent is free from optical brighteners.

2. The water-soluble packaging as claimed in claim 1, wherein the optical brightener is selected from the group consisting of disodium-4,4′

-bis-(2-morpholino-4-anilino-s-triazin-6-ylamino)stilbene disulfonate, disodium-2,2′

-bis-(phenyl-styryl)disulfonate, 4,4′

-bis[(4-anilino-6-[bis(2-hydroxyethyl)amino]-1,3,5-triazin-2-yl)amino]stilbene-2,2′

-disulfonic acid, hexasodium-2,2′

-[vinylene bis[(3-sulfonato-4,1-phenylene)imino[6-(diethylamino)-1,3,5-triazin-4,2-diyl]imino]]bis-(benzene-1,4-disulfonate), 2,2′

-(2,5-thiophenediyl)bis[5-1,1-dimethylethyl)-benzoxazole, 2,5-bis(benzoxazol-2-yl)thiophene, and mixtures thereof.

3. The water-soluble packaging as claimed in claim 1, wherein the color transfer inhibitor is selected from the group consisting of polyvinyl pyrrolidone (PVP), polyvinylimidazole (PVI), copolymers of vinyl pyrrolidone and vinyl imidazole (PVP/PVI), polyvinylpyridine-N oxide, poly-N-carboxymethyl-4-vinylpyridium chloride, polyethylene glycol-modified copolymers of vinyl pyrrolidone and vinyl imidazole, and mixtures thereof.

4. The water-soluble packaging as claimed in claim 1, wherein the quantity of optical brightener is from 0.01 to 0.75% by weight, in relation to the total first liquid detergent or cleaning agent with a low content of water.

5. The water-soluble packaging as claimed in claim 1, wherein the quantity of color transfer inhibitor is from 0.02 to 0.6% by weight, in relation to the total second liquid detergent or cleaning agent with a low content of water.

6. The water-soluble packaging as claimed in claim 1, wherein the water-soluble wrapping contains polyvinyl alcohol or a polyvinyl alcohol copolymer.
