Abstract
The invention relates to surfactant mixtures of hydroxy mixed ethers and polymers, optionally together with typical ingredients of dishwashing detergents and cleaners and optionally other nonionic surfactants and anionic surfactants and to the use of such surfactant mixtures for the preparation of cleaning solutions with improved performance against resoiling.
Claims17
A surfactant mixture comprising:
- (a) one or more hydroxy mixed ethers of the formula:
- R1O—[CH2CH(CH3)O]x[CH2CH(R2)O]yCH2CH(OH)R3 (I)
- wherein R1 represents an alk(en)yl group having from 4 to 22 carbon atoms, each R2 independently represents a hydrogen, a methyl or an ethyl group, R3 represents an alk(en)yl group having from 4 to 22 carbon atoms, x is a number of from 0 to 60, y is a number of from 1 to 80, wherein the [CH2CH(CH3)O]x[CH2CH(R2)O]y portion of the formula (I) represents blocked and/or randomized alkoxylation;
- and (b) at least one polymer comprising a cationic polymer comprising residues of a monomer unit of the formula:
- wherein n represents a number of from 2 to 4, R1a represents a hydrogen or a methyl group and R2a, R3a and R4a each independently represent a hydrogen or a C1-4 alk(en)yl group, X− represents an anion selected from the group consisting of halide anions and monoalkyl anions of sulfuric acid semiester.

- wherein n represents a number of from 2 to 4, R1a represents a hydrogen or a methyl group and R2a, R3a and R4a each independently represent a hydrogen or a C1-4 alk(en)yl group, X− represents an anion selected from the group consisting of halide anions and monoalkyl anions of sulfuric acid semiester;
- and
- (b) combining the surfactant mixture and one or more detergent additives or auxiliaries.
