Abstract (en)
[origin: DE19736906A1] The invention relates to a method for producing fatty acid polyglycol ester sulphates of formula (I) R<1>COO(AO)nSO3M, wherein R<1>CO represents a linear or branched, aliphatic, saturated and/or unsaturated acyl radical with 6 to 22 carbon atoms, AO represents CH2CH2O, CHCH3CH2O and/or CH2CHCH3O, n represents numbers from 0.5 to 5 and M represents a cation, by sulfation of fatty acid polyglycol esters followed by neutralisation. The inventive method is characterised in that the entire neutralisation process is carried out at a pH of 5 to 9.
