Stability

As an acetate, Cis-3-Hexenyl Acetate is susceptible to hydrolysis, which can lead to the formation of acetic acid over time. It demonstrates particular instability in surfactant-rich systems such as shower gel and shampoo bases. For optimal preservation of its integrity, it should be stored in tightly sealed containers in a cool, dry environment, away from direct light, heat, and air.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Moderate

The Cosmetic Ingredient Review (CIR) currently classifies Cis-3-Hexenyl Acetate with 'insufficient data' for a comprehensive safety assessment in cosmetics. However, it is recognized as safe for specific food uses by the FDA (FEMA No. 3171, GRAS No. 4, 25). IFRA guidelines permit its use up to 100% in fine fragrances (Category 4). Typical usage in perfume compounds ranges from 0.010% to 1.000%, averaging 0.100%. While EWG rates it 'LOW' for concerns regarding cancer, allergies, immunotoxicity, and reproductive toxicity, read-across data for a related synonym indicates it is considered a weak sensitizer, suggesting a potential for dermal sensitivity in some individuals.
