ABSTRACT OF THE DISCLOSURE A novel composition is provided herein. The composition contains (A) a bridging agent, (B) a hydrocarbon oil and (C) an organopolysiloxane fluid, in which the organopolysiloxane fluid (C) is immiscible with hydro- carbon oil (B) in the absence of bridging agent (A). The bridging agent is obtained from the reaction of (1) an organopolysiloxane selected from the group consisting of (i) hydroxyl-terminated organopolysiloxanes, (ii) cyclic siloxanes, and (iii) mixtures thereof, in which at least 80 percent of the organic groups are methyl radicals with (2) an alcohol having from 12 to 28 carbon atoms, in which the hydrocarbon group is a saturated or unsaturated branched chain or an unsaturated linear chain. A process is also provided for treating organic fibers therewith. The composition is a miscible organopolysiloxane hydrocarbon oil composition having improved storage stability, which may be applied to organic fibers to improve their lubricating properties.
