Science

Mechanism of Action

As an emollient, Isostearyl Neopentanoate lubricates the skin's surface to impart a notably soft and smooth appearance. It creates a lightweight, breathable occlusive film that effectively minimizes transepidermal water loss (TEWL), providing an indirect moisturizing benefit. The ingredient is fast-absorbing, ensuring rapid integration into the skin without leaving a greasy residue. Within formulations, it acts as a texture enhancer, improving glide and spreadability, reducing tackiness, and facilitating the uniform dispersion of pigments.
