Penetrant JFC-1, chemically known as fatty alcohol polyoxyethylene ether (CAS No.: 9036-19-5), is a nonionic surfactant synthesized by addition polymerization of C₇~C₉ fatty alcohols with ethylene oxide (n≈5), with a molecular weight of about 400~600. The product appears as a colorless to slightly yellowish transparent liquid with an active content ≥99%, making it a high-purity, high-performance industrial penetration aid. The polyoxyethylene ether chain segment in its molecular structure provides excellent hydrophilicity, while the fatty alcohol alkyl chain offers lipophilicity. This amphiphilic structure allows it to rapidly adsorb at liquid-solid and liquid-air interfaces, significantly reducing the system's surface tension (surface tension only 28~32 mN/m), thus achieving the core function of "second-level penetration."
Due to its nonionic nature, JFC-1 exhibits excellent formulation compatibility—it can be well compounded with anionic, cationic, and other nonionic auxiliaries, and remains stable in acidic, alkaline (alkali-resistant), and hard water media without failure due to water quality or pH fluctuations. Its HLB value ranges from 11 to 13, with a cloud point of 45~55°C. It also possesses good emulsifying and dispersing capabilities, synergistically enhancing the overall treatment effect while performing its primary penetration function. Furthermore, this product is low-foaming and has strong penetrating power (penetration time ≤5 seconds), making it particularly suitable for industrial scenarios requiring rapid wetting.
In terms of safety and environmental protection, Penetrant JFC-1 is a non-hazardous substance with a flash point above 100°C and is non-flammable. Its oral LD₅₀ in rats is far greater than 5000 mg/kg (low toxicity), with only mild irritation to skin and eyes (GHS classification: Skin Irritation Category 2 and Eye Irritation Category 2B). It also exhibits good biodegradability and is not a persistent organic pollutant, making it a green auxiliary that balances performance and environmental friendliness. Hai'an Guoli Chemical Co., Ltd. offers various packaging specifications, including 50kg plastic drums, 200kg plastic drums, and IBC totes, for flexible user selection.
