What It Does
Dimethicone is a linear silicone polymer composed of repeating dimethylsiloxane units, creating a flexible chain structure that provides exceptional slip and spreadability. This synthetic silicone forms a breathable, non-occlusive film on skin and hair that locks in moisture while providing a smooth, silky feel without greasiness. Formulators choose dimethicone for its thermal stability, chemical inertness, and ability to improve product texture while delivering long-lasting conditioning benefits.
