Industrial Uses

1. Food & Beverage

  • Packaging Material: Benzophenone is used in the production of food packaging materials. It serves as a UV blocker in plastic packaging to prevent degradation of the food products inside by ultraviolet (UV) light. However, its use is highly regulated due to potential safety concerns about migration into food.
  • Packaging: In the wine industry, benzophenone derivatives can be applied in the packaging materials to provide UV protection, preventing light-induced changes in the quality and taste of the wine.

2. Pharmaceuticals

  • Photosensitizer: Benzophenone is utilized as a photosensitizer in pharmaceuticals, particularly in photodynamic therapy and some drug formulations. It can help in generating reactive oxygen species when exposed to light, which can be beneficial in specific therapeutic applications.
  • Stabilizer: It is also used as a stabilizer in some pharmaceutical formulations to prevent the degradation of active ingredients caused by exposure to light.

3. Personal Care

  • Hair Care Products: Benzophenone is used in hair care products such as shampoos, conditioners, and styling gels to protect the hair from sun damage by filtering UV light, which helps in maintaining hair color and integrity.
  • Nail Care Products: It is also used in nail polishes and treatments to prevent the breakdown of colorants and other components caused by exposure to sunlight.
  • Skin Care Products: Besides sunscreens, benzophenone is found in lotions, creams, and lip balms to provide photoprotection against harmful UV rays, helping prevent skin damage and maintaining the effectiveness of antioxidants and other active ingredients.

4. Polymers & Resins

  • Polymer Stabilizer: Benzophenone is used as a UV stabilizer in plastics and resins to prevent degradation caused by UV exposure, ensuring longer-lasting polymer products.
  • Resin Photoinitiator: It is also a photoinitiator in UV-curable resins, allowing rapid curing during polymerization processes.

5. Fabric & Solutions

  • UV Protection: In the textile industry, benzophenone is used as a UV absorber in fabrics to provide protection against UV radiation. This helps in producing UV-resistant clothing, especially for outdoor and sportswear.

6. Animal Healthcare

  • Pharmaceutical Applications: Benzophenone can be used as an intermediate in the synthesis of veterinary pharmaceuticals, especially those that require UV resistance or stabilization under certain environmental conditions.
