CAS 68390-97-6 Product Introduction:
C16-18 Alkyldimethyl Amines (often referred to as dimethyl tallow amine, though the CAS refers to a broader C16-18 alkyl chain distribution) are a mixture of tertiary amines with long, saturated alkyl chains (primarily hexadecyl and octadecyl).
They typically appear as a colorless to pale yellow liquid or a low-melting solid, with a characteristic amine odor. These compounds are fundamental building blocks in the production of various cationic surfactants and specialty chemicals, owing to their dual hydrophobic (alkyl chains) and hydrophilic (amine group) nature.
Main Uses:
-
Surfactant Manufacturing (Quaternary Ammonium Compounds): This is the primary use. C16-18 Alkyldimethyl Amines are reacted with methyl chloride or similar reagents to produce C16-18 alkyldimethylbenzylammonium chlorides (e.g., Cetrimonium Chloride, Steartrimonium Chloride), which are widely used cationic surfactants and germicides.
-
Personal Care Products: The quaternary ammonium derivatives are key ingredients in hair conditioners, shampoos, and styling products, acting as antistatic agents, emulsifiers, and conditioning agents.
-
Industrial Cleaning and Disinfectants: Quaternary ammonium compounds derived from these amines are potent biocides used in disinfectants, sanitizers, and industrial cleaning formulations.
-
Textile Industry: They are used as fabric softeners, antistatic agents, and dyeing auxiliaries in textile processing.
-
Oilfield Chemicals: Applications include corrosion inhibitors, demulsifiers, and biocides in drilling fluids and production chemicals.
-
Water Treatment: Used as flocculants or slimicides in industrial water treatment processes.
-
Asphalt Emulsifiers: Certain derivatives can function as emulsifiers in asphalt emulsions for road construction
