CAS No. 139-07-1
Molecular formula: C21H38NCl; relative molecular mass: 340.00
Structural formula

I. Performance and Applications:
1227 is a cationic surfactant; it is a non‑oxidizing biocide with broad‑spectrum, high‑efficiency bactericidal and algaecidal activity, effectively controlling the proliferation of bacteria and algae as well as the formation of slime in water. It also exhibits excellent slime‑stripping properties and possesses certain dispersing and penetrating capabilities, while providing moderate oil‑removal, deodorizing, and corrosion‑inhibition effects.
1227 exhibits low toxicity, no cumulative toxicity, and is readily soluble in water, unaffected by water hardness. Consequently, it is widely used in recirculating cooling water systems across industries such as petroleum, chemical processing, power generation, and textiles to control the growth of bacteria and algae, with particularly effective action against sulfate-reducing bacteria. Additionally, 1227 can serve as a biocide and mold inhibitor in the textile printing and dyeing industry, as well as a softening agent, antistatic agent, emulsifier, and conditioning agent.

III. Instructions for Use
1227 is used as a biocide and algaecide, typically at a dosage of 50–100 mg/L; when employed as a slime‑stripping agent, the recommended dose is 200–300 mg/L. An appropriate amount of silicone‑based defoamer may be added as needed. It can be compounded with other biocides, such as isothiazolinones, glutaraldehyde, and dithiocyanomethane, to enhance efficacy; however, it must not be used in combination with chlorophenol‑based agents. After dosing with 1227, any sludge released during the stripping process should be promptly removed by filtration or skimming to prevent deposition once the foam has dissipated.
1227 Do not mix with anionic surfactants such as polyacrylic acid or hydrolyzed polyamide, including in packaging containers and mixing equipment.
IV. Packaging and Storage
1227 is packaged in plastic drums, with each drum containing 25 kg or 200 kg, or as specified by the customer. Store in a cool, well-ventilated indoor location; the shelf life is twelve months.
V. Safety Protection
1227 exhibits no significant skin irritation; if it comes into contact with the skin, rinse thoroughly with water.
