The eco-friendly penetrant JFC is a non-ionic surfactant with C8-C10 fatty alcohol polyoxyethylene ether as its core component. It possesses excellent penetrating power (≤5 seconds), outstanding stability against acids, alkalis, and hard water, as well as broad industrial compatibility. It is a multifunctional high-efficiency auxiliary agent in textile printing and dyeing, industrial cleaning, pesticide emulsification, and other fields.
Detailed Description
The eco-friendly penetrant JFC (CAS No.: 68439-50-9) is produced by Haian Guoli Chemical Co., Ltd. It appears as a colorless to slightly yellow transparent liquid, with the molecular formula C12-14H25-29O(C2H4O)nH (n≈9), a molecular weight of approximately 580, and an active content of ≥99%. This product is a non-ionic surfactant with a pH value (1% aqueous solution) maintained in the neutral range of 5.0~7.0 and an HLB value between 11-13, combining hydrophilicity and lipophilicity, enabling it to exhibit excellent interfacial activity in different systems.
As a general-purpose penetrating wetting agent, the core competitiveness of JFC is reflected in three aspects: First, its penetrating power is extremely strong, with the penetration time measured by the standard canvas sedimentation method not exceeding 5 seconds, allowing rapid wetting and deep penetration into fibers, dirt layers, or gaps between solid particles; second, its chemical stability is excellent, remaining stable in 1%~5% NaOH alkali systems, while also resistant to hard water and acids, maintaining performance under a wide range of pH values and complex water quality conditions; third, its low-foaming characteristic makes it particularly suitable for industrial scenarios sensitive to foam, such as high-speed overflow dyeing machines and high-pressure spray cleaning, avoiding process failures caused by foam accumulation.
Furthermore, the cloud point of this product is 40~50°C, surface tension is in the range of 25~30 mN/m, and the critical micelle concentration (CMC) is only 0.01%~0.1%, meaning significant wetting and emulsifying effects can be achieved at very low dosages, resulting in outstanding economy. Its freezing point is below -10°C, maintaining good fluidity and operational convenience in low-temperature environments, while the flash point is above 150°C, making it a non-flammable liquid with high safety for daily storage and transportation.

Application Suggestions
The eco-friendly penetrant JFC has a wide range of applications. Recommended uses in various fields are as follows:
- Textile Printing and Dyeing Pretreatment: Used as a high-efficiency penetrant in desizing, scouring, and bleaching processes for cotton, linen, synthetic fibers, and blended fabrics. It rapidly wets fiber interiors, enhances capillary effect and whiteness, and its low-foaming property is suitable for high-speed overflow dyeing equipment.
- Leather Processing: Used in the raw hide soaking process to shorten soaking time, promoting the dissolution of salt and soluble proteins; in combination with alkaline auxiliaries during degreasing to emulsify and remove natural oils without damaging the grain layer of the leather surface.
- Paper Deinking: Acts as a penetrating and emulsifying auxiliary to quickly wet ink particles, assisting flotation or washing methods to separate ink from fiber surfaces, improving the brightness of deinked pulp and reducing fiber loss.
- Industrial Hard Surface Cleaning: Used in water-based cleaning formulas for metal parts, molds, pipes, etc. It penetrates the interface between oil stains and substrates, synergizing with surfactants to roll off and emulsify heavy grease, maintaining good cleaning efficiency even at room temperature.
- Pesticide Formulations: As a wetting and dispersing component in wettable powders to improve suspension rate, and as an auxiliary emulsifier in emulsifiable concentrate formulations to enhance dilution stability and field application effects.
- Water-Based Coatings and Inks: Rapidly wets pigment and filler surfaces, aids dispersion, prevents floating and flooding, reduces dynamic surface tension, and improves spreading and leveling on substrates.
Precautions
- Skin and Eye Protection: This product is classified under GHS as Skin Irritation Category 2 and Serious Eye Irritation Category 2. Operators must wear chemical protective gloves, protective clothing, goggles, and face shields to avoid direct contact.
- Environmental Safety: Harmful to aquatic life with long-lasting effects (H412). Do not discharge the product directly into drains, surface waters, or soil. Dispose of according to hazardous waste management regulations after use.
- Storage Conditions: Recommended storage temperature is 5°C~40°C. Store in a cool, dry, well-ventilated area, keep containers tightly closed, and keep away from strong oxidizers, strong acids, strong alkalis, and food and beverages. Check product properties before use after long-term storage.
- Spills and First Aid: In case of skin contact, rinse immediately with plenty of water. In case of eye contact, rinse with clean water for at least 15 minutes and seek medical attention. For small spills, absorb with inert materials such as sand and collect, preventing entry into waterways.
