Ingredient used to impart a sweet, musky odour

What Is Ethylene Brassylate?

Ethylene brassylate is a synthetic fragrance ingredient commonly used in cosmetics and skin care. Its scent is described as sweet and musk-like. It is also used to add flavor to some foods, particularly those with a floral component. Note the spelling of this ingredient’s name doesn’t clearly indicate its fragrance, meaning this is one you’ll need to check closely for if your goal is avoiding unwanted sources of fragrance.\n\nThere isn’t a great depth of research into ethylene brassylate’s impact on skin, though it is generally considered to be non-toxic. Despite this, it does have the potential to cause irritation, a trait it shares with many other fragrance ingredients.\n\nIn its raw form, ethylene brassylate is an almost colorless to pale yellow viscous liquid with a sweet musk-like odor. Typical usage levels in cosmetics range from 0.5–3%.
