METHYL 2-OCTYNOATE

Description

Methyl 2-octynoate is a versatile synthetic fragrance ingredient commonly used in both skincare and haircare formulations. This colorless liquid ester possesses a distinct floral-green scent with subtle fruity undertones, reminiscent of violet leaves. Its molecular structure allows for excellent stability in various product types, making it a popular choice among formulators.

In skincare applications, methyl 2-octynoate serves primarily as a fragrance enhancer, imparting a pleasant aroma to creams, lotions, and serums. While its primary function is olfactory, it can also contribute to masking less desirable scents of other active ingredients. In haircare products, it is often incorporated into shampoos, conditioners, and styling products to provide a fresh, long-lasting fragrance.

It is important to note that methyl 2-octynoate is a known skin sensitizer and potential allergen for some individuals. As such, its concentration in formulations is typically regulated and must be declared on product labels in many jurisdictions. Formulators should exercise caution when incorporating this ingredient, particularly in products intended for sensitive skin or scalp use.
