DIMETHICONE PEG-15 ACETATE.

Valuable / HAIR CONDITIONING, SKIN CONDITIONING, SURFACTANT - CLEANSING, SURFACTANT - EMULSIFYING

DIMETHICONE PEG-15 ACETATE is a multifunctional PEG-modified silicone prized for its advanced skin conditioning and emulsifying properties. It forms a breathable, protective film that significantly reduces water loss, thereby boosting hydration and bestowing a remarkably smooth skin texture. Its unique structure also ensures stable and elegant cosmetic formulations.

Science

Mechanism of Action

This ingredient functions by creating a permeable, protective barrier on the skin's surface, which demonstrably minimizes trans-epidermal water loss. This mechanism directly enhances skin moisturization, leading to a visibly smoother and softer complexion. As a PEG-modified silicone, it also acts as a highly effective emulsifier and surfactant, enabling the stable blending of oil and water phases in products and providing mild cleansing benefits.

Stability

Optimal stability for PEG/PPG dimethicone polymers, including DIMETHICONE PEG-15 ACETATE, is maintained within a pH range of 5.5 to 8.5. Formulations outside this specified range may experience hydrolysis of the polymer over time. The dimethicone component itself is inherently stable, exhibiting resistance to degradation from air, light, and typical cosmetic ingredients, while its PEG modification allows interaction with both water and oil phases.
