Soybean phospholipid series products are extracted from soybean oil residue by new technology. It is a very excellent emulsifier and health food (drug) raw material. It can be used as emulsifier, quick solvent, release agent, antioxidant and dustproof agent in the field of food processing. Used in leather industry, it can reduce the time of softening leather, avoid product color deepening caused by sunlight, and maintain the softness, brightness and toughness of leather. Soybean phospholipid has good emulsifying and dispersing power, and has good compatibility with ammonium nitrate. It can increase the strength of the interface adsorption film of the composite emulsifier, improve the stability of the emulsion, and effectively improve the performance of the explosive. As a natural emulsifier and stabilizer, soybean phospholipid can enhance the dispersion of pigment, easily disperse titanium dioxide and various pigments evenly, prevent pigment precipitation, improve coverage and fluidity, and maintain the brightness of the product.
