METHYLHEPTADIENONE

Description

Methylheptadienone, also known as 6-methyl-5-hepten-2-one, is a naturally occurring volatile compound found in various plants and fruits. This colorless to pale yellow liquid possesses a distinct fruity, citrusy aroma reminiscent of green apples and lemongrass. In haircare formulations, methylheptadienone serves multiple purposes, primarily as a fragrance ingredient and a functional additive.

The compound's molecular structure allows it to act as a mild antimicrobial agent, helping to preserve product integrity and extend shelf life. Its volatile nature contributes to the overall sensory experience of haircare products, providing a fresh, uplifting scent that lingers briefly after application. Methylheptadienone also exhibits mild conditioning properties, helping to improve hair manageability and reduce static electricity.

In shampoos and conditioners, this ingredient is typically used at concentrations between 0.01% to 0.1%. It is generally considered safe for use in cosmetic products and has been approved by regulatory bodies such as the FDA and EU Cosmetics Regulation. However, as with any fragrance component, patch testing is recommended for individuals with sensitive skin or a history of allergic reactions to cosmetic ingredients.
