Its 1g/L aqueous solution (25°C) has a surce tension of 35~40 mN/m, and the critical micelle concentration (CMC) is approximately 1×10⁻⁵ mol/L, indicating that it can effectively reduce the surce tension of water at relatively low concentrations. The product has a melting point of 45~55°C, a flash point greater than 200°C, a density of about 1.06 g/cm³ (25°C), and strong hygroscopicity, requiring moisture-proof storage. The foaming characteristic is low foaming, giving it a natural advantage in applications requiring rapid defoaming or low-foam processes. On the chemical indicator level, the pH values of 1% and 5% aqueous solutions of the product are both stable at 5.0~7.0, close to neutral, with little impact on the acidity or alkalinity of the formulation system; acid value ≤1.0 mg KOH/g, saponification value ≤2.0 mg KOH/g, iodine value ≤2, indicating extremely low content of free acids and ester impurities, with a molecular structure primarily composed of saturated tty chains. The chemical properties are stable, and the activity remains unchanged under conventional acid-base conditions. The hydroxyl value is approximately 15 mg KOH/g, moisture ≤1.0%, free alcohol ≤3%, effective content and solid content both ≥99%, with high purity. In terms of safety and environmental protection, heavy metals (as Pb) ≤10 mg/kg, arsenic ≤2 mg/kg, 28-day biodegradation rate >60%, easily biodegradable, meeting environmental requirements.
