What is Benzophenone (CAS 119-61-9)?

Benzophenone is a versatile organic compound commonly used as a UV filter, photoinitiator, and fragrance compound in a variety of industries. It absorbs ultraviolet (UV) light and prevents materials from degrading due to UV exposure, making it highly effective in sunscreens, cosmetics, and plastics. Benzophenone also serves as a photoinitiator in polymerization reactions and inks, making it an essential ingredient in UV-curable coatings and adhesives.

Applications of Benzophenone (CAS 119-61-9)

1. Cosmetics and Personal Care

• UV Filter: Benzophenone is commonly used in sunscreen and skincare products to protect the skin from harmful UV radiation by absorbing UV rays.

• Fragrance Stabilizer: Often included in perfumes and fragrances to help stabilize and preserve their scent over time.

• Hair care: Used in shampoos, conditioners, and hair treatments to protect hair from UV damage and maintain its natural color.

2. Photoinitiator in Polymers

• UV-Curable Coatings & Inks: Benzophenone is a key ingredient in UV curing systems, helping to initiate the polymerization process when exposed to UV light. It is used in inks, paints, and coatings for fast-drying applications.

• Adhesives & Sealants: As a photoinitiator, it is used in adhesive formulations for improved curing speed and efficiency under UV light.

3. Industrial Use

• Plastic Stabilizer: Benzophenone is incorporated into plastic materials to prevent UV degradation, especially in polymer films and coatings exposed to outdoor conditions.

• Chemical Synthesis: It is involved in various organic synthesis processes, including the production of other chemicals such as benzoyl derivatives and benzophenone-based resins.

4. Photochemistry and Analytical Use

• Laboratory Use: Benzophenone is used in photochemical reactions and photophysical studies due to its ability to absorb UV light.

• Absorbance Standard: It can be used as a calibration standard for UV spectrophotometry.
