Science
Mechanism of Action
This crosspolymer forms a breathable, protective layer on the skin's surface, effectively locking in moisture to support hydration while simultaneously providing a smoother, more supple skin feel. Its unique particulate structure allows for efficient absorption of excess sebum and oil, resulting in a fresh, matte finish. The ingredient's ability to blur the appearance of fine lines and pores is attributed to its light-diffusing, particulate nature. Furthermore, it enhances formulation stability and spreadability, and helps to anchor other active ingredients, offering a robust defense against environmental aggressors.

Dusting Analysis
As a silicone powder, this ingredient can be incorporated into powder cosmetic formulations, which may become airborne during application. The CIR Expert Panel has reviewed dimethicone crosspolymers as safe for use in such products at concentrations up to 46%.
The Formula
Formulation
Stability
This ingredient is insoluble in water but readily disperses in various oils, including silicone fluids and hydrocarbon oils, exhibiting favorable swelling characteristics. It possesses inherent chemical stability and resistance to oxidation, which contributes to extended product shelf life. Its inclusion can enhance the stability of emulsions and is suitable for formulating W/O, O/W, and non-aqueous systems.
Safety
Safety Profile
The CIR Expert Panel has deemed dimethicone crosspolymers, including this ingredient, safe for cosmetic applications. It boasts a very low hazard rating (EWG score of 1), indicating minimal concerns regarding irritation, sensitization, or systemic toxicity. Its substantial molecular size ensures it does not penetrate the skin, thereby preventing systemic absorption. The EU COSING database approves its use for viscosity controlling, skin conditioning, and opacifying functions in both leave-on and rinse-off products. Clinical testing demonstrates its non-cytotoxic nature at full strength.
