Transport classification per the UN Model Regulations / 49 CFR 172.101 Hazardous Materials Table. Confirm against the grade-specific SDS (Section 14) before shipping.
Didecyldimethylammonium chloride (CAS 7173-51-5), or DDAC, is a twin-chain quaternary ammonium compound. It is used as a biocide and material preservative in wood preservation, in industrial water treatment for cooling towers and oilfield flood waters, in laundry and cleaning formulations, and as a cationic surfactant.
Frequently Asked Questions
What is didecyldimethylammonium chloride used for?
Didecyldimethylammonium chloride (DDAC, CAS 7173-51-5) is a twin-chain quaternary ammonium compound used as a biocide and material preservative in wood preservation, for microbiological control in cooling-tower and oilfield flood waters, in laundry and cleaning formulations, and as a cationic surfactant and textile softening agent.
What is the common name for didecyl dimethyl ammonium chloride?
It is most often called DDAC and belongs to the quaternary ammonium compound ("quat") class. Specify by CAS 7173-51-5 and active concentration when ordering, since DDAC is commonly supplied as an aqueous solution at defined strength.
What products contain didecyl dimethyl ammonium chloride?
DDAC is used in wood-treatment formulations, industrial water-treatment programs for cooling towers and oilfield waters, cationic cleaning and laundry products, and textile softening/antistatic agents. RawSource supplies it as a bulk raw material to formulators in these sectors.
What is the CAS number, formula, and concentration of bulk DDAC?
DDAC is CAS 7173-51-5, formula C22H48ClN, in the cationic surfactants family (HS 2923.90). It is typically supplied as an aqueous solution; state your required active percentage so the correct concentration ships.
What is the cost of bulk DDAC?
Bulk pricing depends on active concentration, packaging, volume, and destination. Request a quote with your target quantity and required concentration; a CoA and SDS accompany each shipment.
