What is Dimethicone Crosspolymer?

Dimethicone Crosspolymer is a synthetic polymer created by cross-linking dimethicone, a type of polydimethylsiloxane silicone. This process forms a flexible, three-dimensional network that swells in oils and emollients, commonly used in skincare creams, serums, makeup, and hair products. In formulations, it enhances texture by providing a smooth, silky feel and soft-focus effect, while stabilizing emulsions to prevent separation. It suspends pigments or actives evenly, controls viscosity for better spreadability, and deposits thin films that protect surfaces from moisture loss or environmental factors. Often found in mattifying products for its sebum-absorbing properties and in hair styling for hold without stiffness. Its inert nature makes it suitable across product types, from oil-in-water lotions to anhydrous balms.

Roles in Formulation

This ingredient serves the following purposes in cosmetic formulations:

Emulsion stabilizer
Improves emulsion robustness by preventing droplet coalescence and phase separation, often by thickening, structuring, or strengthening the interfacial layer.
Hair fixative
Provides style hold by forming a film on hair, helping maintain shape, reduce frizz, and improve durability in sprays, gels, and mousses.
Suspending agent
Keeps insoluble particles (pigments, beads, actives) evenly dispersed by increasing viscosity or forming a network, preventing settling and separation.
Viscosity controlling agent
Adjusts thickness to the desired level for stability and usability, improving dispensing, suspension, and texture across many formulation types.
Hair fixing
Improves style retention by depositing film-forming polymers that hold hair in place while balancing stiffness, flexibility, and humidity resistance.

Benefits

Stabilizes emulsions and suspensions for consistent product texture and performance.

Provides a protective film that smooths skin or holds hair styles effectively.
