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.

Claims
