Abstract

Stable aqueous polyolefin wax dispersions contain PA0 A) from 5 to 65% by weight of polyethylene wax or polypropylene wax having a mean particle size of from 1 to 50 .mu.m and an acid number of less than 5 mg of KOH/g of wax and PA0 B) from 0.5 to 20% by weight of glyceride of predominantly ethylenically monounsaturated or polyunsaturated C.sub.16 -C.sub.22 -monocarboxylic acids which may additionally contain hydroxyl groups, which glyceride has been reacted with from 1 to 50 mol of a 1,2-alkylene oxide of 2 to 4 carbon atoms, as a dispersant. These dispersions are suitable for the production of floor and stone polishes, shoe polishes, car polishes, printing inks, print pastes, finishes, packagings, lubricating greases, vaseline, drawing compounds, sealing and insulating materials for electrical parts, aqueous wood glazes, hot-melt coatings, cosmetic formulations and toothpastes, in plastics processing, in papermaking and in corrosion protection, for the treatment of fabrics and yarns and for leather treatment and as parting compounds in gravity die casting, pressure die casting and centrifugal casting of nonferrous metals.
