Abstract
Surface-active composition based on non-ionic surfactants derived from ethoxylated saturated primary fatty alcohols. The composition is characterized in that it contains a solid mixture at ambient temperature of: PA1 (a) at least one non-ionic surface-active compound A of general formula : R--(OCH.sub.2 CH.sub.2).sub.n OH in which R is a C.sub.6 to C.sub.9 alkyl group and n is greater than 6 and may be as high as 15, PA1 (b) at least one non-ionic surface-active compound B of general formula : R'--(OCH.sub.2 CH.sub.2).sub.m OH in which R' is a C.sub.16 to C.sub.20 alkyl group and m is 6 to 15, in which more than half the groups R and R' taken separately are linear. It can be used in detergent formulations, especially pulverulent or liquid syndet compositions for domestic and/or industrial washing and degreasing purposes.
