Diallyldimethylammonium Chloride (DADMAC)

CAS No.: 7398-69-8

EINECS: 230-993-8

Molecular Formula: C8H16

Molecular Weight: 161.5

Structural Formula:

Diallyldimethylammonium Chloride (DADMAC)


DADMAC is a water-soluble monomer of cationic quaternary ammonium salt with high efficiency. There is an alkenyl double bond in the molecular structure, and it can form linear homopolymers and all kinds of copolymers by various polymerization reactions.


Item Index
Appearance Colorless to slight-yellow liquid
Effective content ≥60% ≥65%
pH 5.0~7.0 5.0~7.0

DADMAC is mainly used to produce polymers, to synthesize all kinds of macromolecular water treating agents whose functions are neutralization, absorption, flocculation, purification, and decoloring, showing excellent effect in decoloring, killing algae, and removing organic compounds in wastewater treatment, paper making and textile printing&dyeing industry.

DADMAC is also used as a modifier of synthetic resin to bring products electrical conductivity and antistatic properties.

DADMAC is often used as an additive in daily chemicals to improve and modify product performances. As to petroleum chemicals, DADMAC can be used as a flocculant and blocking agent.

Packing and storage:

Packed in a 200kg/plastic drum or 1000kg/IBC drum.

DADMAC can be stored in a cool (4~30℃) to avoid freezing and heat. We certify that DADMAC at correct storage will meet sales specifications for 12 months from the date of manufacture.
