About 3,6-DIMETHYL-3-OCTANOL

A branched-chain secondary alcohol fragrance with a fresh citrus-woody character and no significant safety concerns.

Detailed Analysis

3,6-Dimethyl-3-octanol is a branched C10 secondary alcohol featuring methyl substituents at positions 3 and 6, creating a tertiary carbon at position 3. This branching and the secondary hydroxyl group give it a distinctive fresh, citrus, and slightly woody odor profile. The compound is listed in CosIng with no restrictions, and the branched structure increases metabolic clearance compared to linear alcohols. As a saturated alcohol, it lacks sensitization alerts and is considered a low-concern fragrance ingredient.
