Description

Cinoxate CAS NO 104-28-9 is an organic compound belonging to the cinnamate ester class, widely recognized for its ability to absorb ultraviolet (UV) light. This property makes it a critical functional ingredient for protecting materials and formulations from UV-induced degradation. It is primarily utilized by manufacturers in the personal care, polymer, and specialty chemical industries seeking effective and stable UV filters.

Application

• Sunscreen and Personal Care Products: Acts as an active UV-B filter in sunscreens, lotions, and daily wear cosmetics to protect skin from sun damage.
• Polymer and Plastic Stabilization: Incorporated into plastics, coatings, and adhesives to prevent yellowing, embrittlement, and loss of mechanical properties caused by UV exposure.
• Cosmetic and Toiletry Formulations: Used in hair care products, lip balms, and makeup to provide product stability and enhance shelf life under light.
• Industrial Coatings and Paints: Serves as a light stabilizer in clear coats, varnishes, and industrial paints to maintain color and gloss.
• Packaging Materials: Added to films and containers to shield packaged goods, especially light-sensitive pharmaceuticals and foods, from harmful UV radiation.
• Research and Development: Employed as a reference standard or key intermediate in the synthesis of novel UV-absorbing compounds and pharmaceutical research.
