Uv Absorber Uv 1577 Cas No.147315-50-2

1. Octocrylene is a UV-B filter that is approved in the USA, Europe, and Japan for use in sun care preparations.
2. Octocrylene is miscible with many cosmetic oils, it can easily be incorporated into the oily phase of an emulsion
3. Octocrylene is hydrophobic and oil-soluble, it is preferred for water-resistant and water-repellant formulations octocrylene is also compatible with all common plasticizers.



Function & Application

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 the skin with a history of photoallergy.



Use:

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 the formulation.
