What It Does

Timbersilk (Methyl Octahydro Tetramethyl Naphthalenyl Ethanone) is a polycyclic musk fragrance ingredient built on a partially hydrogenated naphthalene (decalin) core, giving it a warm, woody, amber-musky scent profile with excellent tenacity and substantivity on skin and fabric. It was developed as an alternative to some older polycyclic musks with less favorable safety profiles, offering formulators a rich, long-lasting woody-musky character at relatively low use levels. Formulators choose Timbersilk for its smooth, non-animalic musk character and its ability to act as a fixative, enhancing the longevity of surrounding fragrance notes in fine fragrances, body care, and home care applications.
