Stearylamine Polyoxyethylene Ether AC-1802 (CAS: 26635-92-7) is a white to slightly yellow waxy solid at room temperature (melting point 45~50°C), with an HLB value of about 4.5. It is a low HLB nonionic surfactant with strong lipophilicity. Under acidic conditions, the amine group protonates and exhibits cationic characteristics. Before use, the appropriate method must be selected according to the specific formulation system: if adding directly, heat it above 50°C to melt into liquid before feeding; if dispersing in aqueous phase, pre-dissolve it in hot water at 70~80°C (it can disperse in cold water but with poor effect), or dissolve in organic solvents such as ethanol or isopropanol before adding to the system.
When used as an antistatic agent in plastics/synthetic fibers, the internal addition type generally recommends 0.3%~1.5% of the resin weight, blending with resin during mixing or extrusion; external coating type can be formulated into a 1%~5% water or alcohol solution for spraying on the product surface. For textile softening/leveling processes, recommended bath ratio is 1:10~1:20, dosage 0.5%~2% (based on fabric weight), treating at 40~60°C for 20~30 minutes. In daily chemical formulations as a conditioner or emulsifier, recommended dosage is 0.5%~3% of the total formula, dissolved in the oil phase by heating before emulsification. For industrial emulsification/dispersion, metalworking fluids, mineral flotation, etc., the recommended dosage range is usually 0.1%~2% of the total system, with specific amounts determined through experimental optimization.
This product has excellent chemical stability, resistant to acids, alkalis, and hard water, maintaining stable performance within pH 3~12; low foaming characteristics make it suitable for circulating systems; amine value 150~165, tertiary amine content ≥95% ensures excellent cationic adsorption performance under acidic conditions. Wear protective gloves and goggles during operation to avoid skin and eye contact.
