The stability and unconventional reactivity of 1,13‐diamino‐4,7,10‐trioxatridecane in the presence of NH 3 , H 2 O 2 , and (NH 4 ) 2 S 2 O 8 are described. The ether‐diamine is an ingredient marketed to hair salons and consumers for so‐called “plex” services to compensate for hair damage during bleaching. The main reaction product identified is an unexpected azanyl ester derivative. This is considered relevant for the safety evaluation when used in cosmetic products. The mechanism of reaction was explored through DFT calculations. This study represents the first attempt to assess the stability of a plex active in an oxidative environment.
