(2), Avoid using in personal care products.
(3), Do not use in nitrosating environment. Reaction of N,N-diethylcyclohexanamine and nitrous acid can not produce nitrosamines, however, reaction of contained secondary amine of N,N-diethylcyclohexanamine and nitrous acid can produce nitrosamines. Nitrosamine is a carcinogen.
Synthesis
Currently, sulfated reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfates.
Generally, lauryl alcohol and sulfur trioxide react through reactor, then N,N-diethylcyclohexanamine neutralizes, finally obtain product.
US patent 8,921,588 (Process for preparing sulfates and/or sulfonates in a micro-reaction system) presents a synthetic process. Conditions: mole ratio of sulfur trioxide and alcohols or other raw materials: 1:1; temperature: 30-60°C; reactor: falling film reactor.
