Science

Mechanism of Action

This ingredient functions by forming a lightweight, occlusive film on the skin's surface, effectively minimizing transepidermal water loss (TEWL) and locking in essential moisture. Beyond its primary emollient action, it significantly improves product spreadability and contributes to formulation stability by aiding in the solubilization of challenging components like sunscreen agents and fragrances, as well as ensuring uniform dispersion of active ingredients and pigments.

Stability

Neopentyl Glycol Diisononanoate is a lipophilic ester with poor water solubility, making it ideally suited for oil-based formulations. While its parent compound, Neopentyl Glycol, is stable across neutral, acidic, and alkaline pH ranges, formulating the ester within oil phases helps optimize its stability and minimize potential hydrolysis.
