Product Technical Details

Product Overview

4-Methylbenzylidene Camphor, commonly known as Enzacamene, is a highly effective organic UV filter specifically engineered to absorb UV-B radiation (280–320 nm). As a camphor-derived molecule with proven photostability and skin compatibility, it is extensively utilized in sun care and daily-use cosmetic products requiring sun protection factor (SPF) claims. Our premium-grade material meets stringent international quality standards for use in dermal applications.

Industrial Applications

As a functional cosmetic active ingredient, 4-Methylbenzylidene Camphor serves as a key UV-B absorber in a wide range of personal care formulations:

Sunscreen lotions, creams, and sprays with SPF ratings
Daily moisturizers and foundations offering broad-spectrum sun protection
Lip balms and after-sun products requiring photostable UV filters
Water-resistant suncare formulations due to its favorable lipophilicity (LogP ≈ 4.95)
