Padimate

Padimate is a chemical compound that has been used as a sunscreen agent. Its chemical name is octyl dimethyl PABA, or 2-ethylhexyl 4-(dimethylamino)benzoate. It belongs to the class of organic compounds known as para-aminobenzoic acid (PABA) derivatives, which are designed to absorb ultraviolet (UV) radiation, specifically UVB rays. Padimate O, a specific formulation, was commonly incorporated into sunscreen lotions, sprays, and other personal care products to help protect the skin from sunburn.

The effectiveness of Padimate O as a UVB absorber made it a popular ingredient for many years. However, like other PABA derivatives, its use has declined in recent decades due to a few factors. Concerns about potential skin sensitivity and allergic reactions in some individuals led to its phasing out by some manufacturers. Additionally, the development of newer sunscreen filters with broader spectrum protection and improved photostability has provided alternative options for consumers and formulators. While less common in new products, Padimate O might still be found in some older formulations or in certain regions. Research has also explored its environmental impact, though this has not been a primary driver for its decreased use in cosmetics.
