FREE-FLOWING AQUEOUS ALKYL SULPHATE PASTES

摘要

The aim of the invention is to provide free-flowing, pumpable aqueous alkyl sulphate pastes with a surfactant content of 30 to 80 per cent by wt. and which have suitable rheological properties but do not contain any additional surfactants to reduce the viscosity. This aim is achieved with surfactant pastes containing 0.5 to 10 % by wt. of unsulphonated fatty alcohols, not more than 0.2 %by wt. of inorganic sulphates plus, optionally, inorganic chlorides. The flow limit of pastes of this kind is at the most 45 Pa at 60 C and/or the viscosity is at the most 6.5 Pa.s at a shear velocity of 10 s-1 and a temperature of 60 C.
