4-Methylbenzylidene camphor is an organic camphor derivative that is used in the cosmetic industry for its ability to protect the skin against UV, specifically UV B radiation.
As such, 4-Methylbenzylidene camphor is used in sunscreen lotions and other skincare products claiming a SPF value.
4-Methylbenzylidene camphor's tradenames include Eusolex 6300 (Merck) and Parsol 5000 (DSM).

All the camphor-derived sunscreens dissipate the photon energy by cis-trans isomerisation.
However, for enzacamene the quantum yield for this isomerization is only between 0.13-0.3.
This low quantum yield means that other photochemical processes are also occurring.
4-Methylbenzylidene camphor is a potent UV filter that protects the skin from sunburn and damage caused by ultraviolet rays.
4-Methylbenzylidene camphor is commonly used in sunscreens, moisturizers, lip balms, and makeup for sun protection.
Additionally, 4-Methylbenzylidene camphor is a photo stabilizer and can be combined with other UV filters to stabilize them and prevent product degradation upon sunlight exposure.

4-Methylbenzylidene camphor a UV-B ray filter, is an endocrine disruptors (ED).
4-Methylbenzylidene camphor is primarily used in cosmetics as a UVB filter to protect skin from sun damage.
4-Methylbenzylidene camphor absorbs UVB rays (290-320 nm), reducing the risk of sunburn and preventing UV-related skin aging.
Commonly included in sunscreens, 4-Methylbenzylidene camphor is also found in day creams, lotions, lip balms, and makeup with SPF.
By converting UV radiation to less harmful energy, 4-Methylbenzylidene camphor 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.
Biological Activity
4-Methylbenzylidene camphor is an ultraviolet light blocker used in cosmetics and sunscreen preparations that also has estrogenic activities.
Since the estrogen receptor (er) ligand type can influence transactivation, 4-Methylbenzylidene camphor is important to obtain information on molecular actions of nonclassical er agonists.
