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.
Claims16
A surfactant mixture comprising:
- (a) one or more hydroxy mixed ethers corresponding to the general formula (I):
- 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 general formula (I) represents blocked and/or randomized alkoxylation;
- and (b) at least one polymer.

A method for improving the wetting behavior of a dishwashing detergent composition, said method comprising:
- (a) providing a surfactant mixture comprising:
- (i) one or more hydroxy mixed ethers corresponding to the general formula (I):
- R1O—[CH2CH(CH3)O]x[CH2CH(R2)O]y—CH2CH(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 general formula (I) represents blocked and/or randomized alkoxylation;
- and (ii) at least one polymer;
- and
- (b) combining the surfactant mixture and one or more detergent additives or auxiliaries.
