ABSTRACT:
The present invention relates to alkyl ether sulfate salts of the general formula Iin-line-formulae description="In-line Formulae" end="lead"?RO—(CH2CH2O)x—(CH2—CHR1O)y—(CH2CH2O)zSO3−M+  (I),in-line-formulae description="In-line Formulae" end="tail"?whereR is an unbranched or branched C8-C18-alkyl radical or mixtures of different unbranched or branched C8-C18-alkyl radicals,R1is an aliphatic radical selected from the group consisting of methyl and ethyl,M+is a cation, selected from the group consisting of alkali metals, NH4+and HNR23+, where R2is selected from the group consisting of unbranched or branched alkyl radicals, CH2CH2OH and CH2CH(OH)CH3,x has a mean value of 0-3,y has a mean value of 1-10,z has a mean value of 0-30,and the quotientA=c⁢⁢m⁢⁢c⁡(RO-(CH2⁢CH2⁢O)z⁢SO3-⁢M+)c⁢⁢m⁢⁢c(RO-(CH2⁢CH2⁢O)x-(CH2-CHR1⁢O)y-(CH2⁢CH2⁢O)z⁢SO3-⁢M+)⁢⁢is>1and to their use as anion surfactant component in laundry detergents and cleaning compositions, in chemical engineering applications or in cosmetics formulations.
