About

A sulphur-containing methoxy thiol fragrance compound with a complex aromatic profile including notes of grapefruit and tropical fruits. Limited toxicological data; used at very low concentrations in fragrances.

Methoxyhexanethiol is a thioether bearing a methoxy group and a mercaptan moiety, contributing a distinctive sulphurous-fruity character to fragrance compositions. Due to the limited toxicological profile available, its use in cosmetic products is restricted to low concentrations in rinse-off products primarily. It is not listed under EU restriction annexes but falls under IFRA guidelines for sulphur-containing fragrance materials.

Known concerns
