Benzophenone-6
Description
Benzophenone-6 (CAS 131-54-4), also known as BP-6, is a UV absorber used to protect materials from photodegradation caused by ultraviolet radiation. It functions by absorbing UV energy before it can break down polymers or active ingredients.
In coatings and industrial paints, BP-6 is incorporated to prevent yellowing and gloss loss on exterior surfaces exposed to sunlight. Plastic and polymer manufacturers use it to extend the service life of films and molded parts.
This chemical is essential for packaging materials where UV stability is a key performance requirement. In printing inks, it helps preserve color integrity and prevents substrate degradation under intense UV exposure.
Personal care formulators have evaluated BP-6 for use in sunscreen and photoprotective products. It provides broad UV absorption across both UVA and UVB ranges, ensuring comprehensive protection for sensitive formulations.
Benzophenone-6 is supplied as a pale yellow to off-white crystalline powder. It is available in technical grade for industrial coating, polymer, and ink applications, with purity specifications typically at 98% or higher.
The quality of the material is confirmed by HPLC to ensure consistency across batches. Cosmetic-grade material meeting relevant regulatory and purity standards is also available for specialized personal care formulation use.
