Abstract
The present invention relates to a pumpable cationic fatty alcohol dispersion having a high content of dispersed fatty alcohol and a low content of cationic dispersant, characterized in that it contains: PA0 (A) from more than 10 to about 25.0% by weight of a linear or branched, primary, saturated C.sub.14 -C.sub.22 fatty alcohol; PA0 (B) from about 0.01 to about 1% by weight of a cationic surface-active compound containing a quaternary ammonium, pyridinium or imidazolinium group and a linear C.sub.8 -C.sub.22 alkyl or 2-hydroxyalkyl group; and PA0 (C) water quantity sufficient to adjust to 100% by weight. It has surprisingly been found that the fatty alcohol dispersions according to the invention can be stabilized with very small quantities of the cationic surface-active compound and that, despite high fatty alcohol contents, a low viscosity and hence good pumpability of the dispersion can be obtained, particularly with low contents of cationic dispersant.
