Expert Verdict

Autoxidation risk requires protection from air and light exposure during storage. Oxidized alpha-phellandrene forms hydroperoxides that are potent sensitizers. Shelf-life is critical and antioxidant protection (e.g., tocopherol, BHT) is recommended in formulations. Potential for respiratory irritation if inhaled at high concentrations.
