Safety
Safety Profile
O-Tolualdehyde is classified as harmful if ingested, capable of causing skin irritation, and serious eye irritation. It poses a risk for allergic skin reactions and respiratory irritation. The International Fragrance Association (IFRA) considers dermal sensitization a critical effect and imposes varying maximum concentration limits based on application site: 0.085% for lip products, 0.51% for face/body products applied with fingertips, and a stricter 0.025% for axillary products. The FDA recognizes its status as a flavoring agent.
