Ethyl Cinnamate

What is Ethyl Cinnamate?

Ethyl cinnamate is a synthetic organic compound, specifically the ethyl ester of cinnamic acid, produced through esterification of cinnamic acid with ethanol. This clear liquid exhibits a sweet, fruity, and slightly balsamic aroma reminiscent of cinnamon. In cosmetics, it primarily serves in fragrance formulations, lip care, and sunscreen products. As a fragrance component, it contributes depth to scent profiles and acts as a fixative to prolong aroma stability. In oral and lip items, it imparts pleasant taste notes. Functioning as a chemical UV filter, it selectively absorbs UVB rays (around 280-320 nm), dissipating energy as heat to shield skin surfaces without physical reflection. Its versatility stems from lipophilic properties, enabling integration into oil-based emulsions at trace levels for sensory enhancement and protective effects.
