In the chemical industry, cationic surfactants hold an important position due to their unique properties, and stearyldimethylbenzyl ammonium chloride (referred to as 1827, CAS No.: 122-19-0) is a standout among them. This pale yellow solid or viscous paste can dissociate in water to produce cationic active groups, with multiple characteristics such as sterilization, emulsification, antistatic, and softening. It is resistant to light, heat, acid, and hard water, featuring strong stability and no volatility, and has become a core raw material in many industries including daily chemicals, textiles, and industrial water treatment.
    In the daily chemical field, 1827 is a "secret weapon" for caring for skin and hair. It is widely used in hair conditioning products, as it can quickly adsorb on the hair surface to form a breathable protective film, reducing friction between cuticles, making dry hair smooth and soft, while enhancing antistatic ability. In products such as moisturizers, body washes, and hair dyes, it can improve emulsification stability, enhance skin moisture, and reduce the irritation of cleaning products to the skin.
    In the textile printing and dyeing industry, 1827 is an efficient leveling agent for cationic dyeing. It can regulate the dyeing rate of dyes, ensuring uniform and bright fabric colors, and also endow fabrics with a soft touch. It can be used as a softening finishing agent for acetate fibers to improve fiber rigidity, and can be used in the same bath with cationic and non-ionic surfactants. The dosage can be flexibly adjusted according to the process, and it can also be used for stripping and re-dyeing of dyeing defects.
   In the field of industrial water treatment, 1827, with its high-efficiency sterilization performance, has become a high-quality bactericide, algaecide, and slime stripper. At a dosage of 20mg/L, its killing rate against iron bacteria and sulfate-reducing bacteria is superior to similar products. It can inhibit microbial reproduction, strip slime from pipelines, ensure the efficient operation of circulating water systems, and extend equipment service life.
    In addition, 1827 can also be used as a thickener for lubricating greases and a raw material for pharmaceutical bactericides, and plays an important role in antistatic treatment in the textile and plastic industries. With the increasing demand for high-quality raw materials in various industries, the application value of this "all-round" surfactant will continue to be explored.
