What is the main component of Penetrant JFC-1?

The main component of Penetrant JFC-1 is fatty alcohol polyoxyethylene ether (C₇~C₉), a classic non-ionic surfactant.

Detailed Description

The chemical category of Penetrant JFC-1 is fatty alcohol polyoxyethylene ether, with the carbon chain of the raw fatty alcohol mainly concentrated in C₇~C₉ (i.e., 7 to 9 carbon atoms). The most representative component among them is the condensation product of 2-ethylhexanol (isooctanol) and ethylene oxide (EO), hence it is also commonly referred to as secondary octanol polyoxyethylene ether or 2-ethylhexanol polyoxyethylene ether. This product is a typical non-ionic surfactant, with a product mass fraction as high as over 99% (active content ≥ 99%), and its appearance is a colorless to slightly yellow transparent liquid.

From the molecular structure perspective, its molecular formula is C₁₂₋₁₄H₂₅₋₂₉O(C₂H₄O)nH, where n≈5, the addition number of ethylene oxide is about 5, and the molecular weight is approximately between 400 and 600. This structure endows the product with unique amphiphilic properties: the fatty alcohol carbon chain provides an oleophilic skeleton, while the polyoxyethylene ether segment imparts hydrophilicity. The ratio between the two allows the product to maintain rapid penetration ability while also possessing good water solubility and oil solubility (easily soluble in water and oil), with an HLB value between 11 and 13, which falls within the optimal range for wetting and penetration performance.

As a flagship product of Guoli Chemical, Penetrant JFC-1, with its high purity (free alcohol content ≤ 1.0%), moderate cloud point (45~55°C), and low surface tension (28~32 mN/m), has become the preferred penetrating auxiliary in industries such as textiles, leather, papermaking, and metalworking.

Technical Parameters

Application Recommendations

Given the chemical properties of its main component, the recommended applications for Penetrant JFC-1 are as follows:

• Textile Printing and Dyeing: Used as a penetrating auxiliary in pretreatment processes (desizing, scouring, bleaching) and dyeing processes. Recommended dosage is 0.1%~0.5% of the working liquor, which can effectively promote the uniform and rapid penetration of dyes and auxiliaries into fibers, avoiding uneven dyeing.
• Leather Processing: In wet processing steps such as soaking, degreasing, and tanning, the recommended dosage is 0.3%~1.0% based on the skin weight, which can accelerate the penetration of chemicals deep into the leather fibers, shortening the process time.
• Metal Surface Treatment: As a penetrating synergistic component for cleaning and degreasing, it is recommended to add at 0.5%~2% of the total cleaning solution volume, which can quickly carry the working liquid into the microscopic pores of the workpiece surface, enhancing degreasing and rust removal efficiency.
• Pesticide Formulations: As a tank-mix penetration synergistic adjuvant, it is recommended to dilute 3000 to 5000 times (i.e., 0.02%~0.03%), which can significantly improve the spreading and penetration ability of the pesticide solution on plant leaves and target surfaces.

Precautions

• This product is a fatty alcohol polyoxyethylene ether non-ionic surfactant, with mild irritation to the skin and eyes. It is recommended to wear gloves and goggles during operation.
• Storage temperature should be maintained between 5~40°C. In low-temperature environments, it may become cloudy or gel, which is a physical change. After warming up and returning to a transparent state, the effectiveness is not affected.
• Although it has good compatibility with anionic, cationic, and non-ionic auxiliaries, direct mixing with strong oxidizing agents or strong reducing agents should be avoided to prevent violent reactions.
