Ethylene dodecanedioate

Ethylene dodecanedioate (CAS 54982-83-1), also known commercially as Zenolide and by the ring descriptor 1,4-dioxacyclohexadecane-5,16-dione, is a macrocyclic musk compound used as a fragrance ingredient.

It delivers a clean, musky scent profile that positions it as a synthetic alternative to animal-derived musks in finished fragrance formulations. In fine fragrance and personal care, it functions as a base-note musk.

This compound contributes depth and longevity to eau de parfum, body lotions, and skin care products. Cosmetic formulators incorporate it into leave-on and rinse-off products where substantivity on skin or hair is required.

Beyond personal care, it is evaluated for use in scented coatings, adhesives, and packaging applications. These uses are ideal where controlled fragrance release is part of the technical product specification.

Ethylene dodecanedioate is typically supplied as a solid, either crystalline powder or flakes. This physical form is suited for weighing and blending into fragrance concentrates or direct formulation processes.

It is available at fragrance-grade purity, with documentation aligned to IFRA compliance requirements that procurement teams routinely request. Bulk and smaller lot sizes are generally offered to serve industrial compounders.

The material meets high industry benchmarks for stability and performance in diverse chemical environments. Specialty fragrance houses utilize this musk for its reliable olfactory profile and consistent quality standards.
