<p>Thickeners of the general formula <IMAGE> wherein R1 is alkyl with 18 to 36 carbon atoms, R2 is hydrogen, methyl or a group of the general formula -(CH2)xR3, R3 being a COOR4 group, in which R4 is hydrogen or alkyl with 1 to 4 carbon atoms, or a -O[CrH2rO-]yR5 group, in which R5 is hydrogen, alkyl with 1 to 4 carbon atoms or acyl, r=2 or 3 and y>/=0, x=2 to 12, n>/=20 and m=0 to 0.5n, are disclosed for hydrocarbon oils, ester oils and vegetable oils. The thickeners are incorporated in the oil in amounts of 2 to 10% by weight, based on the oil. The organopolysiloxanes, effective as thickeners, are usable for many purposes, are effective in small concentrations and are physiologically safe. They are therefore suitable for thickening cosmetic or pharmaceutical preparations based on hydrocarbons, ester oils and vegetable oils.</p> |
