Reactivity Profile Octocrilene is an ester derivative. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides.
Octocrylene is a UVB sunscreen with strong water-resistant properties and a rather broad-band absorption range. It exhibits good photostability, and is being evaluated by many companies as an effective SPF booster and waterproofing enhancer. This is an expensive ingredient with an approved usage level of 7 to 10 percent in both the United States and the European Union.
Although gaining in popularity among formulators, its cost and usage level can limit use.
In addition, some studies are indicating it may cause allergic reactions in skin with a history of photoallergy.
