摘要:
Free flowing aqueous dispersions of non water soluble paraffin hydrocarbons and fats that melt at 30.degree. to 100.degree. C., the dispersions containing up to 60 weight percent of these substances, are produced by using as dispersant up to 1 weight percent of non-ionic surface active ethylene oxide addition products with an HLB value between 12 and 19.6. Preferred dispersions contain 30 to 50 weight percent of fatty alcohols, and, as a dispersant, the products of addition of 20 to 100 moles of ethylene oxide to a fatty alcohol with 16 to 22 carbon atoms, the amount of dispersant being 0.1 to 0.5 weight percent relative to the whole dispersion.

摘要:
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:(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;(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(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.
