A METHOD OF PREPARING ANHYDROUS ALKYL (ETHOXY) SULPHATE COMPOSITIONS

摘要

A method of preparing a substantially anhydrous composition of alkyl (ethoxy) sulphate neutralized with an organic amine base is described, the said composition being suitable for use as a surfactant in an ecodose, i.e. a detergent for washing machine comprised of a pre-dosed liquid detergent for washing machine in a sealed capsule made of a water soluble material, such as for example a polyvinyl alcohol (PVA) film.
