METHYLCYCLOPENTADECANONE

Description

Methylcyclopentadecanone, also known as Exaltolide, is a synthetic musk compound widely used in the fragrance industry and increasingly incorporated into skincare formulations. This macrocyclic lactone possesses a subtle, clean, and long-lasting musky scent that enhances the overall olfactory profile of products. In skincare, it serves dual purposes as both a fragrance ingredient and a potential skin-conditioning agent.

The molecule's structure allows it to penetrate the stratum corneum, potentially aiding in the delivery of other active ingredients. Recent studies suggest that methylcyclopentadecanone may have mild antimicrobial properties, which could contribute to preserving product integrity and potentially supporting skin health. Its low molecular weight enables it to volatilize slowly, providing a persistent scent that doesn't overwhelm other fragrance notes.

Formulators often use methylcyclopentadecanone in concentrations ranging from 0.1% to 1% in leave-on skincare products such as moisturizers, serums, and body lotions. While generally well-tolerated, individuals with sensitive skin or fragrance allergies should exercise caution. As with any fragrance ingredient, patch testing is recommended before widespread use.
