A process for preparing a liquid surfactant composition comprising an anionic surfactant and a nonionic surfactant and having a relatively low water content, whereby essen- tially equimolar amounts of a neutralizing agent and a liquid acid precursor of the anionic surfactant are blended simultaneously in the presence of the nonionic surfactant. The process is especially suitable for preparing mixtures of nonionic and primary alkyl sulphate.
