Science

Mechanism of Action

DIMETHICONE/PEG-3/PPG-15 CROSSPOLYMER primarily functions by creating a protective barrier on the skin's surface. This barrier effectively reduces transepidermal water loss, thereby locking in moisture and maintaining optimal skin hydration. Concurrently, it contributes to a smoother skin texture and a more supple feel. The ingredient also demonstrates the ability to absorb excess oil and sebum, making it beneficial for balancing oily complexions. Crucially, it acts as a film-former and an efficient water-in-silicone emulsifier, which is vital for developing and stabilizing cosmetic emulsions, providing appropriate viscosity and flow.

Stability

This ingredient functions as a highly effective water-in-silicone emulsifier, capable of forming stable micelle structures. This property makes it particularly suitable for 'water drop' cream formulations where a unique texture is desired upon application. It also contributes to stable emulsions, providing desirable viscosity and product flow.

Safety

Safety Profile

CIR Status
Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that dimethicone crosspolymer ingredients, including those closely related like PEG/PPG-15/15 Dimethicone, are safe under current practices of use and concentration. Its component, dimethicone, has been classified as a minimal irritant in most dermal irritation assessments and did not induce sensitization at a 5.0% concentration in clinical repeated insult patch tests. Silicone-based emulsions incorporating similar ingredients have consistently shown no irritation in studies involving human volunteers.
