Abstract: A fluid composition comprises I) a first component and II) second component different from the first component I). The first component I) comprises at least one copolymer. The copolymer can include a cross-linked siloxane (e.g. a cross-linked aminosiloxane), a silicone polyether copolymer (e.g. an (AB)n silicone polyether copolymer), and/or a saccharide siloxane copolymer. The second component II) comprises an organopolysiloxane resin (e.g. an MQ resin) and/or an acrylate copolymer. The fluid composition can further comprise a carrier fluid, such as a silicone, an organic solvent, and/or an organic oil. The fluid composition may have a viscosity of at least 100 mPa·s at 23° C. and exhibit pituitous rheological properties (generally determined from a plot of normal force (in Pascals) vs a perpendicular shear rate in (sec?1)). Also disclosed is a personal care composition that comprises the fluid composition.

Abstract: A method can selectively prepare a compound of formula (IV), where each R1 and each R2 are independently selected from an alkyl group, an aryl group, a halogenated alkyl group, or a halogenated aryl group of 6 to 10 carbon atoms each R3 is an alkane-diyl group, and each R4 is hydrogen or an alkyl group. The method involves hydrosilylation of an organohydrogensiloxane oligomer with a carboxylic acid alkenyl ester using an iridium complex catalyst.

The hydrosilylation reaction product is the reaction product of a first linear organopolysiloxane and a second linear organopolysiloxane. The first linear organopolysiloxane includes (R1R2R3SiO1/2) and (R4R5SiO2/2) units. Each of R1-R5 is 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 (R6R7R8SiO1/2) and (R9R10SiO2/2) units. Each of R6-R10 is independently a hydrocarbon group, polyether group, siloxane group, or polyol group, so long as at least one of R6-R10 is 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.
