Product type
Benzophenone derivatives are a class of organic compounds commonly used in personal care products as UV filters. These compounds absorb ultraviolet light and help protect the skin from harmful effects associated with sun exposure. They are typically synthesized from benzophenone, which serves as a base structure, modified to enhance their efficacy and stability in various formulations.
| Chemical structure | Benzophenone core with various substituents |
| Appearance | White to pale yellow solid or liquid |
| Solubility | Soluble in organic solvents, insoluble in water |
| Melting point | Typically between 60°C to 100°C |
| UV absorption range | 200 nm to 400 nm |
When selecting benzophenone derivatives, buyers should consider the specific UV absorption properties required for their formulations. It is important to specify the desired chemical structure, purity levels, and any regulatory certifications needed for cosmetic use. Additionally, buyers should indicate the quantities required for their production processes to ensure optimal pricing and availability.
