BENZYLIDENE CAMPHOR SULFONIC ACID

Description

Benzylidene camphor sulfonic acid is a potent organic compound utilized in sunscreen formulations for its exceptional UV-filtering properties. This water-soluble ingredient belongs to the family of camphor derivatives and functions primarily as a UVB filter, offering broad-spectrum protection against harmful solar radiation. Its molecular structure allows it to effectively absorb and dissipate UV energy, reducing the risk of sunburn and photoaging.

In skincare formulations, benzylidene camphor sulfonic acid typically appears as a white to off-white crystalline powder. It is particularly valued for its stability in aqueous solutions and its ability to enhance the photostability of other UV filters when used in combination. The ingredient demonstrates high efficacy at relatively low concentrations, making it an efficient choice for sunscreen manufacturers.

While benzylidene camphor sulfonic acid is approved for use in many countries, including those in the European Union, it is not currently approved by the FDA for use in sunscreens in the United States. Safety studies have shown it to have a favorable toxicological profile, with minimal skin penetration and low potential for irritation or sensitization. However, as with all active sunscreen ingredients, ongoing research continues to evaluate its long-term effects and environmental impact.
