Octocrylene CAS#6197-30-4

Octocrylene is an organic compound widely recognized for its potent UV-filtering properties, making it an essential ingredient in sunscreens and other skincare products designed to protect the skin from harmful ultraviolet radiation. With the chemical name 2-(4-Methylbenzyl)-2H-benzotriazole-5-methyl, octocrylene is a stable and photostable molecule that provides broad-spectrum protection against both UVA and UVB rays.

This oil-soluble chemical is valued for its ability to absorb UV radiation effectively, converting it into heat without causing skin irritation or staining clothes. Octocrylene is often used in combination with other UV filters to enhance the sun protection factor (SPF) of formulations, ensuring a balanced and comprehensive defense against sun damage.

As a lipophilic compound, octocrylene is compatible with various cosmetic and dermatological formulations, contributing to the development of lightweight, non-greasy sunscreens. Its chemical structure allows for a high degree of safety and efficacy, making it suitable for a wide range of skin types, including sensitive skin.

In summary, octocrylene is a reliable and efficient UV filter, pivotal in the formulation of modern sunscreens that offer advanced protection against the sun’s harmful effects while maintaining skin comfort and product aesthetics.
