Science
Mechanism of Action
This ingredient operates by breaking down into molecules that can neutralize malodors, particularly those generated by bacterial byproducts, thereby effectively masking unpleasant scents. Its reported antioxidant capacity is believed to stem from its ability to scavenge free radicals, which in turn may help mitigate oxidative damage and support cellular integrity, potentially contributing to anti-aging effects.

Safety
Safety Profile
The Expert Panel for Fragrance Safety has deemed Citronellyl Methylcrotonate safe for cosmetic use within specified limits, based on a No Expected Sensitization Induction Level (NESIL) of 4700 μg/cm². Maximum acceptable concentrations vary by application: 0.36% for lip products, 0.11% for axillary products, and 2.2% for face/body applications. It is not anticipated to be genotoxic, photoirritating, or photoallergenic. Despite its generally low irritancy, individuals with fragrance sensitivities should exercise caution, as allergic reactions have been noted. It is listed as 'Restricted' for EWG VERIFIED products without adequate substantiation and flagged by Environment Canada as a 'Suspected environmental toxin'.
