Octocrylene
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.
Octocrylene is chemically related to cinnamates. It can be used to boost SPF and improve water resistance in a given formulation. Octocrylene is photostable and can improve the photostability of other sunscreens. It is expensive and can present difficulties in formulation.
