Octocrylene, or 2-Ethylhexyl-2-cyano-3,3-diphenyl acrylate, is a pale yellow, viscous liquid, known for its characteristic odor and refractive index of 1.561-1.571. It is widely utilized in sun care products, daily moisturizers, baby sun care items, and decorative cosmetics due to its exceptional properties as an oil-soluble and photostable UV-B filter. In sunscreen formulations, it works synergistically with approved UV-A absorbers to enhance protection against harmful rays, providing the advantage of UV absorption in the short-wave UV-A spectrum. Octocrylene is also instrumental in creating water-resistant products and effectively dissolves other solid sunscreens, such as Avobenzone and Benzophenone-3, thus serving as an SPF booster. Its ability to photostabilize Butyl Methoxydibenzoylmethane and serve as an excellent solubilizer for crystalline UV absorbers enhances its utility in cosmetic formulations. Compatible with methanol, propylene glycol, and various oils, Octocrylene is easy to incorporate into formulations, though it is insoluble in water. It is globally approved for topical use, with concentration limits set by local regulations, and is not intended for ingestion or direct eye contact.
What are the primary applications of Octocrylene in cosmetic products?
Octocrylene is primarily used as a sunscreen in sun care products such as creams and lotions. It is also widely employed in baby sun care products, daily moisturizers, and decorative cosmetics. Its oil-soluble, photostable nature makes it an effective UV-B filter when used with other approved UV-A absorbers.
How does Octocrylene enhance the effectiveness of other sunscreen components?
Octocrylene acts as a photostabilizer, particularly for ingredients like Butyl Methoxydibenzoylmethane, enhancing the effectiveness of other photo-degradable sunscreens such as Avobenzone. It serves as an excellent SPF booster and enables the formulation of water-resistant products by facilitating the dissolution of solid sunscreens like Avobenzone and Benzophenone-3.
Is Octocrylene safe for use in skincare products?
Octocrylene is considered safe for topical application in various skincare products. However, it must not be ingested or come into direct contact with the eyes. Its use is approved worldwide, although the maximum allowable concentration varies according to local regulations.
What are the solubility properties of Octocrylene, and how do they affect its formulation in products?
Octocrylene is an oily viscous liquid that is miscible with methanol, propylene glycol, IPM, mineral oils, plant oils, and silicone oils. However, it is insoluble in water, making it particularly suitable for water-resistant sunscreen formulations. This solubility characteristic allows it to serve as an excellent solubilizer for crystalline UV absorbers.
Why is Octocrylene preferred for formulating water-resistant sunscreens?
Due to its insolubility in water and miscibility with various oils, Octocrylene is ideal for creating water-resistant sunscreen products. Its ability to boost SPF and stabilize other UV absorbers further enhances the longevity and effectiveness of sun protection formulations in aqueous conditions.
