Description
N,N-Dimethyldodecylamine (CAS 112-18-5, EC 203-943-8) is a tertiary aliphatic amine derived from lauric acid, commercially known under abbreviations including DDA and dimethyl lauramine. It carries no assigned E-code. The molecular formula is C14H31N.
In personal care formulations, DDA functions as a conditioning and antistatic agent by adsorbing onto negatively charged hair surfaces and reducing static charge buildup. In coatings and adhesive systems, it acts as an emulsifier and heat stabilizer, improving pigment dispersion and retarding oxidative degradation of the polymer matrix during processing.
This product is supplied as a neat liquid grade and is registered under REACH (EC 203-943-8), with HS code 29211990 applicable for customs classification within the EU. Standard packaging formats include IBC containers and drums. Buyers should confirm grade specification and SDS documentation prior to formulation use.
