General description
Padimate O is a tertiary amine derivative of p-aminobenzoic acid (PABA), which is commonly used as a sunscreen agent in cosmetics and other sunscreen formulations due to its ability to absorb ultraviolet radiations.
Application
Padimate O may be used as a reference standard in the determination of padimate O in cosmetics using high performance liquid chromatography (HPLC).

Employing thermal analysis, we investigated the mechanism of action of novel enhancers and probed phospholipid (PL) versus stratum corneum lipid (SCL) liposomes as model membranes. The enhancers included octyl salicylate (OS), padimate O (PADO) and 2-(1-nonyl)-1,3-dioxolane (ND). The negative controls
