4-Methylbenzylidene Camphor is a potent UV filter that protects the skin from sunburn and damage caused by ultraviolet rays. It is commonly used in sunscreens, moisturizers, lip balms, and makeup for sun protection. Additionally, it is a photo stabilizer and can be combined with other UV filters to stabilize them and prevent product degradation upon sunlight exposure. In its raw form, 4-Methylbenzylidene Camphor appears as a white to off-white crystalline powder that is typically odorless. It is soluble in oil and works best in oil-based formulations. The chemical formula of 4-Methylbenzylidene Camphor is C18H22O.

What is 4-METHYLBENZYLIDENE CAMPHOR used for?
4-Methylbenzylidene Camphor is primarily used in cosmetics as a UVB filter to protect skin from sun damage. It absorbs UVB rays (290-320 nm), reducing the risk of sunburn and preventing UV-related skin aging. Commonly included in sunscreens, it is also found in day creams, lotions, lip balms, and makeup with SPF. By converting UV radiation to less harmful energy, it aids in providing broad-spectrum protection, especially when paired with other UV filters. Additionally, 4-Methylbenzylidene Camphor stabilizes formulations exposed to sunlight, enhancing product performance and longevity. Though effective, alternatives are sometimes preferred due to potential environmental concerns.
Origin
4-Methylbenzylidene Camphor is made by the condensation reaction between camphor, a natural compound from tree raisins, and 4-methylbenzaldehyde - in the presence of an acid or base catalyst. The process typically undergoes further purification to remove by-products.

UV FILTERSafety Profile
4-Methylbenzylidene Camphor is considered safe in the EU at concentrations up to 4%, though it is restricted or unapproved in other regions due to potential endocrine-disrupting effects, particularly on estrogen receptors. Studies suggest it can lead to hormonal activity at higher concentrations. In terms of environmental impact, 4-Methylbenzylidene Camphor is a bioaccumulative compound linked to coral bleaching and aquatic toxicity, which has led some areas to regulate its use in sunscreens. Overall, it is effective but used cautiously, with alternatives preferred for sensitive formulations.
