About

A phenolic fragrance ingredient with a warm, amber, and slightly leathery scent profile. The phenolic structure raises concerns about sensitisation and potential oestrogenic activity, warranting careful use.

Tetrahydronaphthalenol (also called tetrahydrolinalool or its isomer) is an aromatic alcohol used as a fragrance ingredient providing warm, amber, and slightly woody notes. The phenolic/aromatic nature of the compound raises concerns about skin sensitisation potential, and the SCCS has flagged substances with structural similarities for potential concern. IFRA guidelines restrict its maximum concentration in different product types.

Skin benefits

  • Contributes warm, amber fragrance notes with good substantivity

Known concerns

  • Potential skin sensitisation requiring concentration restrictions
