In the JFC series product line of Guoli Chemical, penetrant JFC-2 (isooctanol polyoxyethylene ether, CAS: 9002-93-1) is positioned as a high-performance nonionic penetrant. Compared with the same series of penetrant JFC-1 (fatty alcohol polyoxyethylene ether) and environmentally friendly penetrant JFC, the outstanding advantage of JFC-2 lies in its extremely fast penetration speed — requiring only ≤5 seconds to complete penetration in a 0.1% aqueous solution using the standard canvas settling method, which is a leading indicator among similar products. Meanwhile, JFC-2 has an HLB value of 13.5, offering a better hydrophilic-lipophilic balance, giving it an edge in wetting and spreading capabilities.
Compared with the anionic ultra-strong penetrant JFC-E (dioctyl sodium sulfosuccinate), JFC-2 demonstrates greater formulation flexibility due to its nonionic nature — it can be freely compounded with anionic, cationic, and amphoteric auxiliaries without ionic conflicts causing precipitation or failure. This characteristic makes JFC-2 particularly valuable in complex industrial formulations, especially in textile printing, dyeing, and industrial cleaning fields requiring the synergistic action of multiple auxiliaries. Additionally, JFC-2 exhibits good chemical tolerance to acids, alkalis, and hard water media, maintaining stable activity even in process environments with significant pH fluctuations.
From the perspective of product data completeness, JFC-2 possesses the most comprehensive technical parameter system in Guoli Chemical's database, covering key indicators such as penetrating power (≤5 seconds), surface tension (approximately 30 mN/m), critical micelle concentration (approximately 130 mg/L), cloud point (65~70°C), hydroxyl value (approximately 90), and kinematic viscosity (approximately 240 mm²/s, 25°C), providing reliable references for users in formulation design and process optimization. This data transparency is a significant advantage not found in other JFC variants.

Textile Pretreatment: JFC-2 is an ideal choice for desizing, scouring, bleaching, and mercerizing processes, with recommended dosage of 0.1%~0.5% of the working liquor. Its fast penetration characteristics can significantly shorten process time, improve treatment uniformity, and fabric quality. When used as a penetrating and leveling agent in dyeing, it can effectively reduce color spots, color differences, and other issues.
Industrial Hard Surface Cleaning: In metal degreaser and hard surface cleaner formulations, the recommended addition amount is 1%~5%, quickly penetrating oil layers to achieve deep cleaning. Combined with its acid and alkali resistance, it is suitable for various cleaning systems such as pickling and alkaline cleaning.
Pesticide Formulations: Used in wettable powders, suspension concentrates, and emulsifiable concentrates, the recommended addition is 0.5%~2%, significantly improving the wetting, spreading, and penetration ability of the pesticide liquid on plant leaves and target surfaces, enhancing the efficiency of active ingredients. Its nonionic nature ensures good compatibility with various pesticide active ingredients.
Leather Processing and Paper Industry: In soaking and degreasing processes, the recommended dosage is 0.3%~1%, accelerating the penetration of treatment liquids into the deep layers of leather or felt fiber gaps, shortening processing cycles and improving treatment effects.
