Detergent and cleaning agent with polyalkoxylated polyamine and adjusted non-ionic surfactant

摘要

The primary washing power of detergents and cleaning agents, particularly with regard to protein-containing soiling, was to be improved. This was achieved substantially by incorporating a combination of polyalkoxylated polyamine with alkoxylated C8-C22 alcohol having an average alkoxylation degree in the range from 1 to 5.

主权项

1. A cleaning agent comprising a combination of from 0.3% by weight to 20% by weight polyalkoxylated polyamines which are obtainable by reacting polyamines having primary, secondary and tertiary amino groups, wherein the ratio of primary to secondary amino groups is 1:0.7 to 1:1, and wherein the ratio of primary to tertiary amino groups is 1:0.5 to 1:0.8, with alkylene oxide, and from 0.2% by weight to 10% by weight of a first nonionic surfactant selected from the group consisting of alkoxylated C8-C18 alcohols having an average alkoxylation number in the range of 1 to 5; and wherein the agent further comprises a surfactant system comprising:
a) from 0.1% by weight to 18% by weight synthetic anionic surfactants selected from the group consisting of alkyl sulfates, alkenyl sulfates, ether sulfates, α-sulfo esters, sulfosuccinates, and alkylbenzene sulfonates; b) from 2% by weight to 25% by weight of second nonionic surfactant, different from said first nonionic surfactant, selected from the group of nonionic surfactants consisting of fatty alkyl polyglycosides, fatty alkyl polyalkoxylates, fatty acid polyhydroxyamides, ethoxylation and propoxylation products of fatty alkylamines, vicinal diols, fatty acid alkyl esters, and fatty acid amides.
