Penetrant JFC-1 (CAS number: 9036-19-5), chemical name: fatty alcohol polyoxyethylene ether (C₇~C₉), also known as secondary octanol polyoxyethylene ether, polyoxyethylene fatty alcohol ether, 2-ethylhexanol polyoxyethylene ether, etc. The product appears as a colorless to slightly yellow transparent liquid, belonging to the classic nonionic surfactant, produced by Haian Guoli Chemical Co., Ltd.
Its core advantages are: ①Ultra-fast wetting – can quickly reduce the surface tension of liquids, achieving second-level wetting and significantly improving work efficiency; ②All-around compatibility – the nonionic nature provides good compatibility with anionic, cationic, and other nonionic auxiliaries, offering flexible formulation adaptation; ③Strong stability – stable performance in acidic, alkaline, and hard water media, adapting to complex process environments; ④Synergistic enhancement – also has excellent emulsifying and dispersing capabilities, helping to improve the overall treatment effect of the system.
From a safety perspective, this product is not classified as dangerous goods, has a high flash point, is non-flammable, has good biodegradability, and is relatively environmentally friendly. It is mildly irritating to skin and eyes; it is recommended to wear basic protective equipment during operation. The oral LD50 for rats is greater than 5000 mg/kg, indicating low toxicity.
1. Textile Printing and Dyeing: Used in desizing, scouring, bleaching, dyeing, and finishing processes to promote uniform and rapid penetration of dye liquor and auxiliaries into fibers, preventing uneven dyeing from the source and improving dye uptake and leveling effect.
2. Leather Manufacturing: In processes such as soaking, degreasing, and tanning, it accelerates the penetration of chemicals into the fiber interior, shortening process time and improving the softness and fullness of the finished leather.
3. Papermaking Industry: Applied in pulp treatment and surface sizing, it enhances the penetration of chemical solutions into fibers, helping to improve the physical strength and surface properties of paper.
4. Metal Processing: In cleaning, degreasing, and surface pretreatment, it quickly carries the working solution into the microstructure of the workpiece surface, ensuring treatment consistency and cleanliness.
5. Pesticide Formulations: Used as a penetration enhancer added to emulsifiable concentrates, wettable powders, and aqueous solutions to improve the spreading and penetration of the pesticide solution on plant leaves and target surfaces, thereby enhancing the effective utilization of the pesticide.
6. Daily Chemicals: Used in household detergents and cleaning product formulations to strengthen decontamination and penetration, helping the cleaning components penetrate into fibers and dirt to enhance cleaning effect.

Penetrant JFC-1 is typically used as a wetting and penetrating aid in formulations. The recommended dosage depends on the specific process. In textile pretreatment, the general dosage is 0.1%~0.5% of the working solution; in pesticide formulations, it can be added as a synergist as needed. Due to its nonionic nature, the proportion can be flexibly adjusted when compounded with various auxiliaries.
