PEG-12 DIMETHICONE/PPG-20 CROSSPOLYMER.

Valuable

PEG-12 DIMETHICONE/PPG-20 CROSSPOLYMER is a versatile silicone elastomer that significantly enhances the texture and sensory profile of skincare formulations. It imparts a desirable smooth, powdery feel, reduces tack, and optimizes spreadability, while also providing skin conditioning benefits.

Science

Mechanism of Action

Functioning primarily as a texturizing agent and rheology modifier, PEG-12 DIMETHICONE/PPG-20 CROSSPOLYMER contributes to a refined sensory experience. It creates a smooth, non-greasy texture and enhances the effortless glide of a product across the skin, simultaneously mitigating any tacky sensation. Beyond its textural contributions, this ingredient acts as an emollient and humectant, supporting skin hydration and helping to minimize transepidermal water loss. Furthermore, its unique structure facilitates the delivery of both oil-soluble and water-soluble active ingredients into the skin.

Stability

This crosspolymer exhibits high chemical stability, resisting degradation in cosmetic formulations. Typically supplied as an elastomer pre-dispersed in a silicone carrier, its performance is influenced by factors such as crosslink density, the PEG/PPG ratio, and the specific carrier used. It is particularly effective in silicone and anhydrous systems for building texture and improving slip. While some hydrophilic grades offer compatibility in systems containing polar fractions, careful formulation balance is essential to prevent structural instability or phase separation. Proper dispersion, adequate shear, and the correct order of addition are critical for achieving uniform performance and desired sensorial properties. It can incorporate up to 75% water and 40% glycerin, demonstrating significant versatility in emulsion creation.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has deemed dimethicone crosspolymer ingredients, including PEG-12 DIMETHICONE/PPG-20 CROSSPOLYMER, safe for use in cosmetics under current practices and concentrations. However, as a PEG-containing ingredient, there is a theoretical potential for contamination with toxic impurities such as ethylene oxide and 1,4-dioxane, both identified as carcinogens. Consequently, it is advisable to avoid using products containing PEGs on broken or irritated skin. While the FDA has designated this ingredient safe for general or specific limited use in food, this designation does not directly apply to cosmetic use.
