What is Ethylene Brassylate and where is it found?

A Fragrance Ingredient used for MASKING Chemical odors and in PERFUMES

Ethylene Brassylate is a fragrance used in topical medications and in perfumes, particularly in antibiotic/steroid/eczema creams as a masking agent.  It is a synthetic Musk fragrance.  Quite often, individuals sensitive to Ethylene Brassylate are also allergic to other components of the preparation.  Ethylene Brassylate is a colorless oily liquid with a clean, smooth and sweet scent. In cosmetics and personal care products, Ethylene Brassylate is used in the formulation of aftershave lotions, bath products, bubble baths, cleansing products, hair care products, lipsticks, moisturizers, perfumes and colognes and skin care products.  Currently, this is being investigated as a skin allergen due to its Estrogenic activity and interaction with cell membranes.

We do not recommend using any product with Ethylene Brassylate in it.  It has been found to be toxic to aquatic life with long lasting effects

Due to it is estrogenic activity it is a possible long term cancer causing substance.
