According to the product database of Guoli Chemical, Detergent AR-815 is an anionic surfactant compounded with sodium alkylbenzene sulfonate and fatty alcohol polyoxyethylene ether. It appears as a light yellow transparent viscous liquid, easily soluble in water, and has low-foam characteristics. This product has excellent chemical stability, capable of withstanding acids, alkalis, and hard water environments. It performs exceptionally well under alkaline conditions, withstanding NaOH concentrations up to 200 g/L.
In terms of performance indicators, the effective active ingredient content of Detergent AR-815 is not less than 30%, with an HLB value of 13.5 (hydrophilic-lipophilic balance value), indicating strong hydrophilicity and good emulsification and dispersion capabilities. The penetration ability is ≤30 seconds, meaning it can quickly wet and penetrate fiber interstices, effectively stripping oil stains and impurities. The pH value of a 1% aqueous solution ranges from 7.0 to 9.0, close to neutral to weakly alkaline, with relatively high safety in use.
It should be noted that some physicochemical parameters of Detergent AR-815 in the database are marked as "No parameter available," such as cloud point, surface tension, critical micelle concentration, flash point, refractive index, kinematic viscosity, etc. No specific values have been provided in the current product technical specifications. It is recommended to conduct functional testing and verification based on process requirements before practical application.

Based on its physicochemical properties, Detergent AR-815 is particularly suitable for textile printing and dyeing pretreatment processes, including scouring and soaping of polyester, nylon, and their blended fabrics, as well as desizing of cotton and linen fabrics. The recommended working solution concentration is usually 0.5~2.0 g/L (the specific dosage should be optimized according to fabric type, oil stain degree, and equipment conditions). In alkaline scouring processes, it can be used in combination with appropriate amounts of soda ash or caustic soda to fully leverage its alkali resistance advantage.
In metal processing cleaning, it can be used for degreasing and deoiling of steel, copper, aluminum, and other metal parts. The recommended operating temperature is 40~80°C, with better results when used with ultrasonic or spray cleaning equipment. Due to its low-foam characteristics, it is less likely to cause overflow issues in circulating pump washing and continuous cleaning equipment. It is also suitable for leather degreasing, plastic parts cleaning, and other industrial cleaning scenarios requiring low foam.
