A padimate is either of two organic compounds related to PABA and used in sunscreen.
Some of the ingredients contained in chemical sunblock designed to prevent UVB radiation include: · Cinnamates · OMC (Octyl Methoxycinnamate) · Ethylhexyl p-Methoxycinnamate · Salicylates · OCS (Octyl Salicytate) · Homomenthyl Salicylate · Triethanolamine · PABA (Para Aminobenzoic Acid)· Padimate O · Padimate A · Glyceryl Aminobenzoate · Octyl Dimethyl Paba · Octocrylene · Zinc Oxide · Titanium Oxide The sunscreen ingredients that are used to absorb UVA radiation include: · Benzoophenones · Oxybenzone · Dioxybenzone · Avobenzone
Classic compounds include zinc oxide and titanium dioxide, used in a variety of sunscreens and sunblocks. A synthetic chemical, PABA (4-aminobenzoic acid) is also in use, primarily as insoluble "Padimate O" after some studies suggested photocarcinogenic effects.
