Abstract: A particular class of tertiary alcohol substituted organosilicone polymers are provided which comprise chemically combined monofunctional siloxy units (M.sub.o) and difunctional siloxy units (D.sub.o) and, for every two moles of M.sub.o, an average of from about two to about 100 silicon-bonded tertiary alcohol groups (Q) and an average of from about 2 to about 30 silicon-bonded E.degree. groups where E.degree. is hydrogen or a polyoxyalkylene block (E). When E.degree. is hydrogen, the polymers are tertiary alcohol-substituted polyalkylsiloxane hydrides and, when E.degree. is E, the polymers are tertiary alcohol-substituted polyalkylsiloxane-polyoxyalkylene copolymers. The monofunctional siloxy units encompassed by M.sub.o have at least two alkyls bonded to the respective silicon atoms thereof and the difunctional siloxy units encompassed by D.sub.o have at least one alkyl bonded to the respective silicon atoms thereof, the remaining group bonded to silicon of said M.sub.o and D.sub.
