Description

Methyl Heptenone, also known as 6-Methyl-5-hepten-2-one or Sulcatone, is a volatile aroma chemical with a distinctive fresh, green-citrus character. Its odor combines lemony and lemongrass-like freshness with fruity nuances reminiscent of apple and banana, alongside a characteristic slightly fatty or musty ketonic facet. It occurs naturally in several essential oils, including lemongrass, citronella, palmarosa and lemon oils.

In perfumery, Methyl Heptenone is mainly used as a fresh citrus and green modifier. It can brighten citrus compositions and introduce a naturalistic lemongrass effect while adding subtle fruity complexity. It is particularly useful in fresh, hesperidic, green and aromatic compositions, as well as soap and functional-fragrance applications. Its top-note character makes it valuable for creating an immediate impression of freshness before softer heart materials take over.

Perfumers' Tip

Methyl Heptenone works best as a citrus-green accent rather than a dominant note. Combine it with lemon, bergamot or lemongrass materials for a natural fresh effect, or pair it with green and fruity ingredients to emphasize its apple-like character. Start at a low level because its fatty and musty facets can become more noticeable as the dosage increases.
