Dimethicone/Polyglycerin-3 Crosspolymer

What is Dimethicone/Polyglycerin-3 Crosspolymer?

Dimethicone/Polyglycerin-3 Crosspolymer is a lab-synthesized ingredient formed by chemically linking dimethicone, a polydimethylsiloxane silicone, with polyglycerin-3, a branched polyglycerol ether. This creates a water-compatible, elastic gel matrix. Typically found in lotions, gels, cleansers, and serums, it works by building a thin, flexible network that traps water and oils, preventing separation in emulsions. It adjusts product thickness for easy spreading, forms a smooth barrier to support hydration retention, and delivers a lightweight, velvety finish without greasiness. Its hydrophilic properties allow high water loads in clear, non-sticky formulas, aiding in micellar and spray products for gentle cleansing and conditioning.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Surfactant
Lowers surface tension to enable cleansing, emulsifying, and foaming; central to shampoos, body washes, and many emulsions and micellar systems.
Cleansing agent
Removes dirt, oil, and impurities by lowering surface tension and forming micelles, enabling soils to be lifted and rinsed away from skin, hair, or teeth.
Emulsifying agent
Enables stable mixing of oil and water phases by forming an interfacial film, helping create lotions, creams, and cleansers with consistent texture.
Solubilizing agent
Helps incorporate oils and fragrance into water-based formulas by forming micro-solutions, enabling clear sprays, toners, and micellar products.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
