Description

Dibutyl Sulfide is a highly potent sulfur-containing aroma chemical with a distinctive savory and sulfurous character. Its odor can be described as onion-like, alliaceous, meaty and slightly rubbery, with an intense character even at very low concentrations. Because of its powerful odor profile, it is primarily used as a specialty material rather than a conventional fragrance ingredient.

In perfumery and aroma composition, Dibutyl Sulfide can be useful for creating realistic savory, roasted, meaty, vegetable and sulfurous effects. It may also be used in trace amounts to add complexity and realism to certain natural-style compositions. Its strong character makes precise weighing and careful dilution particularly important. When used appropriately, tiny quantities can provide a convincing naturalistic nuance that would be difficult to achieve with conventional floral or fruity materials.

Perfumers' Tip

Dibutyl Sulfide is an extremely high-impact material and should be handled at very low dilution levels. Use it only in trace quantities when a composition needs a realistic sulfurous, savory or vegetal nuance; overuse can quickly overpower the entire accord.
