Description

Ethylene Brassylate is a high-purity macrocyclic musk ester, prized for its clean, musky-woody odor profile with excellent stability and substantivity. This versatile fragrance ingredient is a cornerstone in modern perfumery, offering a cost-effective alternative to natural musks while delivering superior performance and longevity in formulations. It is an essential component for fragrance houses and manufacturers of fine fragrances, personal care products, detergents, and household cleaners seeking to create sophisticated and long-lasting scent experiences.

Application

• Fine Fragrances & Perfumery: A key base note in perfumes, eau de toilettes, and colognes, providing a warm, musky, and persistent dry-down.
• Personal Care Products: Used in soaps, shower gels, shampoos, deodorants, and lotions to impart a clean, soft musk note with excellent skin adhesion.
• Household & Laundry Care: Enhances the scent profile and longevity of laundry detergents, fabric softeners, and all-purpose cleaners.
• Cosmetic & Toiletry Formulations: Employed in scented creams, powders, and other cosmetic products for its stable and non-discoloring properties.
• Functional Fragrances: Ideal for air fresheners, candles, and diffusers due to its excellent volatility and tenacity.
• Industrial Deodorants: Used in masking agents for industrial products and environments.
