Science

Mechanism of Action

As a cationic silicone derivative, SILICONE QUATERNIUM-9 interacts electrostatically with the negatively charged surface of the skin, anchoring itself to provide conditioning benefits. It forms a breathable, non-occlusive film that acts as a subtle barrier, helping to minimize transepidermal water loss and thereby support skin hydration. This molecular architecture also facilitates an exceptionally smooth glide upon application, improving the overall sensory experience and finish of skincare products.
