Benzophenone application
Sunscreen cosmetics is the hot new products of cosmetics, almost all sunscreens contain benzophenone compound on the current market. Benzophenone compounds that protect the skin from harm, often is used to produce high product. In recent years, the cosmetics consumption of benzophenone grows continuesly. Recent studies suggest that fluorescence is also a harmful ultraviolet light source, so benzophenone expands the range of applications in the field of cosmetics, it has been extended to hair conditioners, lotions and lipsticks. In addition, the perfume fixative agent also can give spice sweet flavor, is used in many perfumes and soap flavor.
Banana Boat company has developed a UVA ultraviolet-absorbing technology called AvoTriplex, which is benzophenone-based, adding a stabilizer to prevent the benzophenone from breaking down in the sun. Enhancer is also added into the formula, and stabilizer may act synergistically, to optimize benzophenone sunscreen capacity.
