Abstract (en)

[origin: EP0814152A2] A method for the preparation of high bulk weight, solid washing or cleaning agents containing anionic surfactants and builders comprises the use of solid 8-22C alkyl sulphates as surfactants and the inclusion of 3-10 wt.% (with respect to the alkyl sulphate) carboxylic acid alkyl ester alkoxylate(s) of formula (I) and/or hydrolysis products to improve detergent solubility: R<1>-CO2-(AO)m-R<2> (I) R<1> = 5-21C alkyl optionally containing unsaturated bonds; R<2> = H or 1-6C alkyl; AO = 2-4C alkylene oxide; and n = 1-60 (3-12).
