The super penetrating agent JFC-E (chemical name: Dioctyl sulfosuccinate sodium salt, CAS No.: 1639-66-3) is a high-purity anionic penetrating agent launched by Haian County Guoli Chemical Co., Ltd. Unlike the common JFC series non-ionic penetrating agents on the market (such as penetrating agent JFC-1 fatty alcohol polyoxyethylene ether, high-temperature penetrating agent JFC-M isomeric tridecanol polyoxyethylene ether), JFC-E belongs to sulfosuccinate sodium salt surfactants. Its unique molecular structure—double ester bond with sulfonic group—gives it extremely high interfacial activity. The penetration speed measured by the standard canvas settling method is only ≤5 seconds, far superior to conventional non-ionic penetrating agents.
Compared to the same sulfosuccinate series rapid penetrating agent T (fast T-50, fast T-70B, etc.), the biggest differentiating advantage of JFC-E is its ultra-high effective content (≥99%) and ultra-high purity (diester content ≥98%). Common fast T products on the market are mostly 50%~75% alcohol-water solutions, while JFC-E is nearly pure. This means higher penetration efficiency at the same dosage, and lower transportation and storage costs. Additionally, its strict indicators such as moisture content ≤0.5%, free alcohol ≤1%, and acid value ≤1 mg KOH/g ensure batch stability and formulation reliability in high-end application scenarios (such as pesticide formulations, precision cleaning).
Compared to phosphate ester penetrating agents (such as alkali-resistant penetrating agent AEP, low-foam penetrating agent SF), JFC-E maintains excellent alkali resistance (can withstand 200g/L NaOH), while having faster penetration speed, lower surface tension (28~32 mN/m), and good compounding compatibility with anionic, cationic, and amphoteric auxiliaries. It is less prone to precipitation or stratification, offering more flexible and free formulation design.
