Science
Mechanism of Action
Functions as a lipophilic solvent that reduces oil phase viscosity in emulsions, facilitating the dissolution of poorly soluble active ingredients. Upon application, it helps create uniform film formation on the skin surface while being rapidly metabolized into harmless succinic acid and short-chain alcohols, minimizing dermal penetration.

Dusting Analysis
This ingredient serves a specific technical function as a UV filter solvent and is typically used at effective concentrations rather than being dusted.
The Formula
Formulation
Stability
Ester structure makes it vulnerable to hydrolysis at extreme pH levels below 3.0 or above 9.0. Most stable in standard cosmetic emulsion pH range of 5.0-7.0.
