polysorbate 60 food, lemon-colored to orange oily liquid or semi-gel, with slight special odor and slightly bitter taste. It is a non-ionic surfactant and has been widely used in the fields of food, daily chemicals, medicine, and mechanical processing. There are two synthetic methods, one-step method and two-step method. The products produced by the traditional one-step base catalysis method contain many by-products such as diesters and triesters, which are dark in color and unstable in quality, and can only be used for petroleum and washing and textile industries. The two-step method is divided into two types: first etherification and then esterification and first esterification and then etherification. The product obtained by first etherification and then esterification has a dark color, high content of diester and triester, and poor quality performance while the product obtained by the post-etherification production process has darker color, higher hydroxyl value, poor fluidity and transparency in liquid state, but higher monoester yield and good quality performance, which is widely used by domestic and foreign manufacturers.
