  • Applications

    Etocrylene (CAS 5232-99-5) is primarily used as a UV filter in cosmetics and personal care products, especially in sunscreens and SPF-containing moisturizers, owing to its UV absorption and photostability. It is commonly formulated to enhance UV filtering performance and to help stabilize other UV filters (such as avobenzone) in sunscreen formulations, thereby improving overall SPF durability. Beyond cosmetics, it can be used as a UV absorber in certain coatings and plastics formulations to protect substrates from UV degradation, and may find use as a stabilization aid in related cosmetic ingredient systems.
