Citronellyl Methylcrotonate

What is Citronellyl Methylcrotonate?

Citronellyl methylcrotonate is a synthetic ester derived from citronellol, a naturally occurring alcohol in essential oils like citronella, and methylcrotonic acid. Chemically, it belongs to the class of unsaturated esters valued in perfumery for their volatility and scent profile. In skincare and cosmetic formulations, it serves primarily in the fragrance category, where it evaporates gradually to release a sweet, fruity-floral aroma reminiscent of roses and citrus. This compound integrates into emulsions, gels, and cleansers at low levels, enhancing the product's sensory appeal by imparting character to the scent and neutralizing off-notes from active ingredients or preservatives. Its role supports emotional and experiential aspects of personal care routines without altering product texture or stability.
