Abstract

A process for preparing hydrophobic agents which comprises slaking caustic lime with water containing a protective colloid, a salt of an acid having the formula R(O).sub.a SO.sub.3 H in which R is selected from the group consisting of substituted or unsubstituted monovalent hydrocarbon radicals and a is 0 or 1 and an organopolysiloxane emulsion having on the average 0.8 to 1.8 SiC-bonded hydrocarbon radicals per silicon atom.
