Description

7-Methoxy-3,7-dimethyl-2-octanol is a synthetic sandalwood-type aroma chemical with a sweet, clean, soft woody and floral character. It is also known as 3,7-dimethyl-7-methoxyoctan-2-ol and is commercially associated with the name Osyrol. Fragrance references describe its odor as sandalwood-like, with sweet, soapy, floral and woody nuances.

In perfumery, this material is valuable for constructing smooth sandalwood accords and adding a soft woody foundation to floral and modern fragrance compositions. Its clean character allows it to bridge floral notes with woody bases while providing warmth and roundness. It is used in fine fragrances as well as soaps, toiletries, shampoos and household fragrance applications.

The material is particularly useful when a formula requires a clean, creamy and polished sandalwood effect rather than an intensely dry or smoky wood character. It can function as both a structural woody ingredient and a supporting modifier, making it suitable for beginners learning to build sandalwood and floral-woody accords.

Perfumers' Tip

Use 7-Methoxy-3,7-dimethyl-2-octanol as a smooth sandalwood backbone in floral-woody compositions. It works particularly well when combined with other sandalwood materials to create a fuller and more dimensional woody accord.

For a modern clean effect, combine it with Hedione, Iso E Super and soft musks. For a richer oriental direction, pair it with patchouli, amber materials and creamy sandalwood notes.
