Environmentally friendly penetrant JFC (CAS number: 68439-50-9), also known as penetrant JFC, fatty alcohol polyoxyethylene ether, polyoxyethylene fatty alcohol ether, wetting agent JFC, is a classic nonionic surfactant product produced by Haian Guoli Chemical Co., Ltd. Its appearance is a colorless to slightly yellow transparent liquid, with excellent penetration, wetting, and emulsifying capabilities, making it an indispensable high-efficiency functional additive in industrial formulations.
This product is known for its excellent chemical stability, maintaining high performance under a wide pH range (acid and alkali resistant) and hard water conditions, without failing due to changes in water quality or process conditions. At the same time, JFC has good compatibility and can be used together with anionic, cationic, and other nonionic surfactants and various additives, providing great flexibility in formulation design.
In terms of safety, this product is a non-flammable liquid (flash point above 150°C), but it should be noted that it is irritating to skin and eyes (GHS classification: Skin irritation Category 2, Serious eye irritation Category 2). Personal protective equipment such as protective gloves and goggles should be worn during operation.
1. Textile Printing and Dyeing Pretreatment Penetrant — In pretreatment processes such as desizing, scouring, and bleaching of cotton, linen, synthetic fibers, and their blends, JFC can rapidly wet the fiber, allowing the working solution to penetrate evenly into the yarn interior, significantly improving wicking and whiteness. Its low-foaming characteristic makes it particularly suitable for high-speed overflow dyeing machines.
2. Leather Processing Soaking and Degreasing — Used in the soaking process of raw hides, it accelerates the penetration of water into the fiber interior, shortens soaking time, and promotes the dissolution of salts and soluble proteins in the hide; when used with alkaline additives in the degreasing stage, it effectively emulsifies and removes natural oils without damaging the grain layer of the leather surface.
3. Papermaking Industry Deinking — As a penetration and emulsification aid in the waste paper deinking process, it rapidly wets ink particles and penetrates the fiber-ink interface, promoting ink detachment and dispersion through flotation or washing methods, improving the brightness of deinked pulp and reducing fiber loss.
4. Industrial Hard Surface Cleaning — Suitable for water-based cleaning formulations for metal parts, molds, pipes, etc., its excellent penetration power allows it to enter the gaps between oil stains and substrates, rapidly rolling off and emulsifying heavy oil stains, maintaining good cleaning efficiency even at room temperature.
5. Pesticide Emulsification Enhancement — Used as a wetting and dispersing component in wettable powders, it improves the wetting speed and suspension rate of the active ingredient particles in water; in emulsifiable concentrate formulations, it serves as an auxiliary emulsifier, improving the spontaneous dispersion and dilution stability of the emulsion, reducing spray drift, and enhancing field application effects.
6. Wetting and Dispersion in Water-based Coatings and Inks — In latex paints, water-based wood coatings, and water-based ink systems, it rapidly wets the surface of pigments and fillers, assisting mechanical shear to achieve efficient deaggregation and stable dispersion, preventing pigment agglomeration and floating, while reducing the dynamic surface tension of the system and improving substrate wetting and leveling.

It is recommended to conduct small-scale tests to determine the optimal dosage based on specific process conditions before use. When used as a penetrant, the conventional recommended dosage is 0.1% to 0.5% of the working solution (specific adjustments are required based on actual processes); in pesticide formulations as an emulsification-enhancing component, the reference addition amount is 2% to 8% of the total formulation. Storage temperature is recommended to be maintained between 5°C and 40°C. Before use after long-term storage, check whether the appearance of the product is normal.
This product is irritating to skin and eyes (H315/H319). Protective gloves, protective clothing, protective goggles, and protective masks must be worn during operation. In case of skin contact, wash with plenty of water. If it gets into eyes, rinse carefully with water for several minutes, remove contact lenses if present, and continue rinsing. If irritation persists, seek medical attention immediately. This product is harmful to aquatic life with long-lasting effects (H412). Do not discharge directly into sewers, surface water, or soil. Waste disposal must be carried out in accordance with local, regional, national, and international regulations.
