Benzyldimethylstearylammonium Chloride CAS 122-19-0
Benzyldimethylstearylammonium Chloride (can also be called Stearyldimethylbenzylammonium Chloride) of the CAS number is 122-19-0. Stearalkonium chloride is a typical quaternary ammonium salt cationic surfactant. Due to the presence of long-chain alkyl, benzyl and quaternary ammonium cationic groups in its molecular structure, it possesses both surface activity and bactericidal properties, and is widely used in multiple fields.
Stearalkonium chloride is mostly white to light yellow powder, granules or waxy solid at room temperature. When the purity is lower, it may be a viscous liquid. We can provide stearalkonium chloride with purity of 80%, 95% and 99%.

1. Textile industry
Softener: Adsorbs on the fiber surface to form a directional arrangement, reducing friction between fibers (especially improving the stiffness of polyester and acrylic fibers).
Antistatic agent: Neutralizes the surface charge of the fiber to prevent static adsorption during spinning/weaving (better when combined with glycerides).
Technical points:
The dosage is usually 0.5%-2% of the fabric weight, and the applicable pH range is (4-9).
Stearalkonium chloride may affect the color fastness and needs to be used in post-dyeing treatment;
2. Oilfield chemicals
Application scenarios: Drilling fluid sterilization: inhibits the reproduction of anaerobic bacteria and prevents the generation of H₂S gas (combined with glutaraldehyde to enhance the effect).
Corrosion inhibitor: forms a hydrophobic film on the metal surface to block water/oxygen contact (the corrosion inhibition efficiency for carbon steel can reach more than 70%).
Precautions: Stearalkonium chloride needs to be compounded with corrosion inhibitors (such as imidazolines) to cope with high temperature and high salt environments.
3. Daily chemicals and disinfection field
Disinfectant/bactericide: Stearalkonium chloride is used for disinfecting skin and mucous membranes (such as medical mucous membrane disinfection), household surfaces (such as floors and furniture), and public facilities (such as swimming pool water and air conditioning systems). Stearalkonium chloride can also be used as a component of mouthwash and contact lens care solution (concentration should be controlled to avoid irritation).
Personal care: Benzyldimethylstearylammonium chloride as antistatic agent and softening agent in shampoo, hair conditioner, reduce hair short-tempered; Stearalkonium chloride helps to kill bacteria in body wash and prevent the imbalance of skin flora.
4. Other special applications
Papermaking industry: as a wet strength agent to improve the softness of paper (used in conjunction with polyamide epoxy resin).
Coating antiseptic: Benzyldimethylstearylammonium chloride can prevent water-based coatings from mildewing (addition amount 0.05-0.1%).
Agriculture: Disinfection of greenhouse tools, seed coating and sterilization.
