  • Applications

    Potassium cinnamate (CAS 16089-48-8) is the potassium salt of cinnamic acid. In industrial practice, it is considered a fragrance ingredient and a precursor for cinnamate esters used in fragrance and flavor applications; it is also used in cosmetics and personal care as a fragrance component or aroma carrier; in household and cleaning products, it can serve as a fragrance additive; in the field of polymers and coatings, it is evaluated as a precursor for cinnamate-containing compounds used as additives or monomers for plastics and coatings.
