Stability

Isoamyl Octanoate demonstrates stability under normal conditions but can be sensitive to extreme temperatures, light, and is susceptible to hydrolysis by strong acids or alkalis. To maintain integrity, storage in a tightly sealed container at room temperature (25-40°C), away from direct heat and light, is recommended; temperatures exceeding 40°C should be avoided.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk Moderate

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) assessed Isoamyl Octanoate in 1996, concluding no safety concern at current levels of intake when used as a flavoring agent, a status echoed by the FDA (21 CFR 172.515). An updated safety assessment by the Research Institute for Fragrance Materials (RIFM) was published in 2023. While generally considered safe for its intended uses, aggregated GHS classifications for the raw material indicate potential for skin irritation in 25.7% of reports, serious eye irritation in 24.8% of reports, and respiratory irritation in 23.8% of reports. However, 74.3% of reports suggest it does not meet GHS hazard criteria.
