Stability
The ingredient demonstrates inherent stability; however, formulators must exercise caution. It is incompatible with strong oxidizing agents, which can lead to combustion. Furthermore, use in nitrosating environments is strictly contra-indicated due to the potential formation of carcinogenic nitrosamines from the reaction of triethanolamine's secondary amine with nitrous acid.

- nitrosating environments
Safety
Safety Profile
The CIR Expert Panel deems amino acid alkyl amides, including this ingredient, safe for cosmetic use when precisely formulated to be non-irritating. Products containing TEA-related components must be engineered to prevent nitrosamine formation, and free diethanolamine (DEA) levels must not exceed 0.64%. The ingredient's solid form has the potential to irritate the skin, eyes, and respiratory system. Its use is not recommended in children's products involving direct, prolonged skin contact, such as skincare or shampoos.
