  • Applications

    2-Ethylhexyl cinnamate (CAS 16397-78-7) is widely used as a UV filter in cosmetics and personal care products; it also functions as a UV stabilizer in polymeric materials and coatings, helping to reduce fading and degradation from light exposure; it is added to coatings and inks to improve resistance to sunlight; it is used in packaging materials to protect contents from UV light; and it can be incorporated into adhesives to improve light stability and extend product life under outdoor or illuminated conditions.
