Abstract

A pituitous silicone fluid includes a hydrosilylation reaction product and a carrier fluid. The hydrosilylation reaction product is the reaction product of a first linear organopolysiloxane and a second linear organopolysiloxane. The first linear organopolysiloxane includes (RRRSiO) and (RRSiO) units. Each of R-Ris independently a hydrocarbon group so long as at least one of R1-R5 is an alkenyl group. In addition, the first linear organopolysiloxane has a degree of polymerization of from 100 to 15,000. The second linear organopolysiloxane includes (RRRSiO) and (RRSiO) units. Each of R-Ris independently a hydrocarbon group, polyether group, siloxane group, or polyol group, so long as at least one of R-Ris a hydrogen atom. In addition, the second linear organopolysiloxane has a degree of polymerization of from 4 to 1,000. The hydrosilylation reaction product includes alkenyl or Si—H functionality. Personal care compositions can include the pituitous silicone fluid.
