Ethylene Brassylate

What is Ethylene Brassylate?

Ethylene Brassylate is a synthetic fragrance compound classified as a macrocyclic musk, featuring a large cyclic diester structure derived from brassilic acid and ethylene glycol. It falls under the perfume category in cosmetics, where it primarily delivers a mild, powdery musky aroma to elevate product sensory qualities. In formulations, it functions by stabilizing scents as a fixative, effectively covering off-notes from other components through masking, and contributing a light tonic effect for refreshed skin texture. This ingredient appears in creams, lotions, and perfumes at trace levels, enhancing overall appeal while maintaining formulation integrity due to its low volatility and compatibility.
