Dusting Analysis
Geranyl Crotonate functions as a fragrance ingredient rather than an active compound with dermatological benefits. Its inclusion in formulations is for sensory appeal, not for targeted skin improvement.
The Formula
Formulation
Stability
As a terpene ester containing multiple carbon-carbon double bonds, Geranyl Crotonate exhibits chemical reactivity and potential for stereoisomerism. It is susceptible to hydrolysis, particularly when exposed to extreme pH conditions, which may compromise its stability in formulations lacking pH control.
Safety
Safety Profile
The Research Institute for Fragrance Materials (RIFM) Expert Panel has concluded Geranyl Crotonate is safe as used, based on their comprehensive safety assessment. While not expected to be genotoxic, supported by read-across analogs and negative results in the Blue-Screen assay (despite positive cytotoxicity), a human maximization test at 6900 µg/cm² demonstrated no skin sensitization reactions. A No Expected Sensitization Induction Level (NESIL) of 4700 µg/cm² was established. Maximum acceptable concentrations vary significantly by product type: 2.2% for face/body applied by fingertips; 0.51% for leave-on body lotions, face moisturizers, hand creams, and baby creams/oils/talc; 0.36% for lip products; 2.0% for fine fragrances; and 0.11% for axillae products.
