Padimate O
What is Padimate O?
Padimate O, chemically known as ethylhexyl dimethyl PABA, is a synthetic organic compound derived from p-aminobenzoic acid esters. It serves as a chemical ultraviolet filter in the cosmetic category of sunscreens and sun protection products. This ingredient primarily targets UVB rays in the wavelength range of 290-320 nanometers. Upon application, it absorbs high-energy UV photons, leading to electronic excitation within the molecule. The energy is then released harmlessly as lower-energy heat or fluorescence, preventing UV penetration into deeper skin layers. Formulated at concentrations up to 8% in products, it contributes to broad-spectrum or targeted UVB defense, often in lotions, sprays, and water-resistant formulations. Developed to minimize the sensitivity issues of earlier PABA sunscreens, it remains a staple in certain global markets for daily sun exposure scenarios.
