About
A phenyl-substituted pentanol used as a fragrance ingredient providing floral, rosy, and slightly fatty notes. The saturated alcohol structure and aromatic ring offer a favorable safety profile compared to unsaturated or reactive analogs.
DL-1-Phenylpentan-2-ol is a phenyl-substituted secondary alcohol with a C5 carbon chain. The 1-phenyl-2-hydroxyalkane structure is characteristic of fragrance materials that are metabolically relatively stable due to the saturated chain. The benzyl alcohol moiety is a known fragrance allergen (declared under EU Annex III), but the overall molecule's sensitization profile is determined by the specific structure. It is not listed in EU Annex II (banned substances), suggesting permitted cosmetic use.
