  • SURFACTANT MIXTURE COMPRISING BRANCHED SHORT-CHAIN AND BRANCHED LONG-CHAIN COMPONENTS
    Publication number: 20110260101
    Abstract: The present invention relates to a surfactant mixture comprising (A) a short-chain component comprising the alkoxylation product of alkanols, where the alkanols have 8 to 12 carbon atoms and the average number of alkoxy groups per alkanol group in the alkoxylation product assumes a value from 0.1 to 30, the alkoxy groups are C2-10-alkoxy groups and the alkanols have an average degree of branching of at least 1; and (B) a long-chain component comprising the alkoxylation product of alkanols, where the alkanols have 15 to 19 carbon atoms and the average number of alkoxy groups per alkanol group in the alkoxylation product assumes a value from 0.1 to 30, the alkoxy groups are C2-10-alkoxy groups and the alkanols have an average degree of branching of at least 2.5; and/or phosphate esters, sulfate esters and ether carboxylates thereof. The present invention also relates to formulations comprising such surfactant mixtures, to methods of producing the surfactant mixtures and to their use.
