一般描述
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.
应用
Padimate O may be used as a reference standard in the determination of padimate O in cosmetics using high performance liquid chromatography (HPLC).
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

The interaction between the UV filter, 2-ethylhexyl-p-dimethylaminobenzoate, and unmodified and modified alpha-, beta- or gamma-cyclodextrins was studied in water by phase-solubility analysis. Of the cyclodextrins available, only hydroxypropyl-beta-cyclodextrin caused a marked increase in the aqueous solubility of 2-ethylhexyl-p-dimethylaminobenzoate. The data
