Mechanism of Action
PEG-8 Dimethicone functions as an emollient by creating a protective physical barrier on the skin's surface, which effectively reduces transepidermal water loss and seals in hydration. This action contributes to a smoother skin appearance, diminishing the visibility of fine lines and wrinkles. As a synthetic polymer, it also binds moisture, enhancing skin hydration. Additionally, it significantly improves the sensory profile of products by imparting a better skin feel, cushion, texture, and slip, and can act as a solvent to facilitate the penetration of other active ingredients.

Formulation
Stability
This water-soluble, nonionic dimethicone copolyol can be integrated into the water phase of formulations. It is crucial to avoid heating PEG-8 Dimethicone above 50°C (125°F). For emulsion systems, it should be added once the mixture has cooled to 50°C. Optimal storage requires tightly sealed containers in a cool, dry, well-ventilated environment, away from direct sunlight and heat.
