Bis-PEG-12 Dimethicone

PEG / Ethoxylated

What is Bis-PEG-12 Dimethicone?

Bis-PEG-12 Dimethicone is a synthetic silicone copolymer consisting of a dimethicone backbone with polyethylene glycol chains (PEG-12) attached at both ends. This structure enhances its water dispersibility compared to traditional silicones. Primarily used in hair care products like shampoos and conditioners, as well as skincare formulations such as lotions and serums, it functions by forming a thin, flexible film on surfaces. This film reduces friction between hair strands or on skin, improving slip and ease of application. The PEG modification allows better compatibility with water-based formulas, aiding emulsification and even distribution without a heavy residue. It contributes to product sensory appeal by providing a silky texture during use.
