Reference Information

hydrophilic-lipophilic balance (HLB value)    18.8

content analysis    ethylene oxide content was determined by the OT-36 method.

usage limit    ADI 0~25mg/kg(FAO/WHO,2001). Safe for use in food (FDA,§ 172.834.2000). There are reports of kidney stones.

Use    This product is used as an emulsifier for oils and esters during liquid or paste emulsification in the production of lubricating oil. It can also be used as thickeners and stabilizers in paper powder coating, lubricants and softeners for textiles, lubricants for multiplex transmission wires in cable pipes, and lubricants for paper sizing.

used in cosmetics, pharmaceutical emulsifiers, soap-based thickeners, softeners, emulsion stabilizers, etc.

production method    put 1.07 mol polyethylene glycol and 0.49 mol boric acid into the reaction kettle and heat to 110 °c, vacuum was applied to 0367 MPa, and the reaction was carried out for 2 h to form borate ester. P-toluenesulfonic acid was then added as a catalyst and 1 mol of stearic acid was added as a reactant. After reacting at 140 ℃ for 3~4 h, the acid value was measured by sampling, and the reaction was completed when the acid value was reduced to about 10 mgKOH/g. The feed liquid was driven into a neutralization kettle, and neutralization was performed to discharge waste water. When hot mixing molding, cooling packaging is the finished product.
