Abstract
Official abstract text for this publication.
The present invention relates to the use of bis-pyranonylmethanes in detergents and cleaning agents to improve the washing or cleaning performance in regard to bleachable stains.
First claim
Opening claim text (preview).
What is claimed is: 1. A detergent or cleaning agent, comprising a compound of the general formula (I), where R 1 , R 2 , R 3 , and R 4 independently of one another stand for hydrogen, an alkyl group having 1 to 20 C atoms, (CH 2 ) n OR 5 , (CH 2 ) n COOR 6 , (CH 2 ) n CONR 7 R 8 , or SO 3 H, wherein R 5 , R 6 , R 7 , and R 8 independently of one another stand for hydrogen or an alkyl group having 1 to 20 C atoms, and n stands for a number from 0 to 6, and whereby the chains of the alkyl groups may also be interrupted by heteroatoms such as O, N, or S, and/or the alkyl groups may also be hydroxy- and/or amino-substituted; and wherein the agent further comprises components of textile detergents selected from the group consisting of builders and surfactants. 2. The agent according to claim 1 , wherein the compound of general formula (I) comprises 0.001% by weight to 20% by weight of the agent. 3. The agent according to claim 1 , wherein it comprises no oxidative bleaching agents selected from the group consisting of hypochlorites, hydrogen peroxide, substances yielding hydrogen peroxide, and peroxy acids. 4. The agent according to claim 1 , characterized in that R 1 and R 3 are the same in the compounds of the general formula (I). 5. The agent according to claim 1 , characterized in that R 2 and R 4 are the same in the compounds of the general formula (I). 6. The agent according to claim 1 , characterized in that R 1 and/or R 3 are hydrogen in the compound according to general formula (I). 7. The agent according to claim 1 , characterized in that R 2 and/or R 4 are CH 2 OH or CH 2 CH 2 COOH in the compound according to general formula (I).
