Safety

CIR Status
Not reviewed
Max tested
0.14%
Sensitization risk Moderate

The Research Institute for Fragrance Materials (RIFM) has conducted a comprehensive safety assessment, which underpins the International Fragrance Association (IFRA) safe use standards. It carries a potential for skin sensitization in a small fraction of individuals, leading to temporary reactions such as redness, bumps, or itchiness upon repeated contact. Maximum acceptable concentrations are precisely defined by product category; for facial moisturizers, this is 0.14%, while general face/body products applied with fingertips allow up to 0.60%. Cis-3-Hexenyl Methyl Carbonate is not expected to be genotoxic, phototoxic, or photoallergenic. While a related material (methanol) has undergone CIR review, Cis-3-Hexenyl Methyl Carbonate itself has not been directly evaluated by CIR, SCCS, or FDA.
