What is Propylene Glycol Stearate?

Propylene glycol stearate is a class of food additives developed in the 1950s. As a food additive, propylene glycol ester has been approved for use by the United States, Japan, Canada, Denmark, China and other countries as well as Europe, the United Nations Food and Agriculture Organization and the World Health Organization. As a food emulsifier, propylene glycol stearate is second only to monoglycerides, sorbitan esters, soybean phospholipids in foreign countries, and is one of the world’s six largest food emulsifiers. Japan’s demand in 1995 was about 1,000 tons, that of the United States was 6,500 tons, and that of Western Europe was 1,200 tons. Except for the molecularly distilled monopropyl ester of Guangdong Chemical Industry Research Institute, the rest are basically non-molecularly distilled products. There is a big gap between the output and the scope of application compared with foreign countries, and further development is needed.

Propylene Glycol Stearate Uses

  1. Propylene glycol stearate is used in the daily chemical industry to make cream cosmetics, so that the cream can increase lubricity, delicateness and stability, and has moisturizing effect, such as used in lipstick. In the pharmaceutical industry, it is used to make emulsions, ointments, suppositories and other medicaments.
  2. Propylene glycol stearate is used as a W/O type food emulsifier, which has foaming, foam stability and emulsifying properties. It is often used in cakes to increase its specific volume. my country stipulates that it can be used in cakes, and the maximum usage amount is 2.0g/kg.

Applications of Propylene Glycol Stearate

Propylene glycol stearate is milky white solid at room temperature. Not soluble or dispersed in water and glycerin, soluble in propylene glycol, isopropanol and other solvents when heated. The hydrophobic part of its molecular structure is dominant, thus giving it water-in-oil emulsifying properties. There is no mesocrystal in water. Monopropyl ester exists in a-crystal form, without polymorphism, but has a-crystal tendency or tends to a-crystal form, and can stabilize x-crystal form of other emulsifiers, and has good gas-filling properties. These characteristics determine its scope of application.

1. Cakes: Propylene glycol stearate combined with monoglyceride and other emulsifiers is widely used in the production of pastries, especially cakes. For example, 60% of monopropyl ester, 24% of monoglyceride and 15% of lactoylglyceride are mixed and made into powder. The cake is mixed with emulsifier, which can make the cake have a significant improvement in temperature and special water capacity. At the same time, the cake has soft tissue, fine and uniform particle structure and excellent eating quality. Monopropyl ester can also be combined with sucrose ester or sorbic acid ester to make ointment-like instant cake oil, which can shorten the mixing time. This emulsifier is particularly tolerant to the addition method. It has good strength when whipping, stirring and baking, and is used to make muffins and sponge cakes. Some domestic monopropyl esters are used in the preparation of instant cake oil. In addition, it can also be prepared as a powder foaming agent, which has strong emulsifying and foaming power, and can be used in pastry production.

Liquid shortening and whipping cream: Monopropyl ester is especially easy to prepare liquid shortening because of its strong lipophilicity. Adding 8-10% monopropyl ester to soybean oil and sunflower oil can obtain uniform and storage-stable shortening containing emulsifiers, which can be used to prepare pastries and cakes. 9~12% monopropyl ester is mixed with a small amount of monoglyceride as a foaming cream emulsifier.

In addition, monopropyl ester is used in soy product defoamer, instant rice, bread, foamed butter, etc. Generally speaking, propylene glycol stearate is rarely used alone, and it is generally used in combination with other emulsifiers. It is used more in pastry and shortening, and its use in other aspects is gradually increasing.

Preparation of Propylene Glycol Stearate

Flow diagram:

Include stearic acid, propylene glycol as well as a driver to a four-neck flask equipped with a stirrer, a thermostat, a brief reflux column and a nitrogen inlet tube. The reaction was carried out at 130-200 ° C for several hours under a nitrogen environment. After the reaction, cool down, reduce the effects of, vacuumize, gather unreacted propylene glycol, add a suitable amount of decolorizing agent to decolorize according to the shade deepness, and then acquire propylene glycol stearate. The product is a light yellow transparent fluid when it melts, as well as a milky white strong at room temperature.
