About
An alkyl sulfide specialty fragrance. Extremely potent odor; limited public data and sulfide hazard profile support a cautious score.
Dibutyl sulphide (CAS 544-40-1) is a symmetrical dialkyl sulfide used in perfumery only at extreme trace (ppb) dosage for savory/pungent accords. Pure material carries GHS skin/eye irritation and environmental toxicity hazard labels. Public toxicology data for cosmetic use are sparse. Not listed on EU Annex II. The combination of potent odor, hazard labels, and data gap warrants conservative scoring.
