What is Propylene Glycol Stearate?

Propylene glycol stearate is a course of artificial additive established in the 1950s. As a preservative, propylene glycol ester has been approved for use by the USA, Japan, Canada, Denmark, China as well as various other countries as well as Europe, the United Nations Food as well as Agriculture Organization and the Globe Health And Wellness Organization. As a food emulsifier, propylene glycol stearate is 2nd just to monoglycerides, sorbitan esters, soybean phospholipids in foreign countries, and is among the world’s 6 largest food emulsifiers. Japan’s need in 1995 was about 1,000 heaps, that of the United States was 6,500 tons, which of Western Europe was 1,200 tons. Except for the molecularly distilled monopropyl ester of Guangdong Chemical Sector Research Study Institute, the remainder are primarily non-molecularly distilled items. There is a big space between the output as well as the extent of application compared with international nations, and also additional growth is required.

Propylene Glycol Stearate Uses

  1. Propylene glycol stearate is made use of in the everyday chemical industry to make cream cosmetics, so that the lotion can enhance lubricity, delicateness and also security, and has moisturizing result, such as used in lipstick. In the pharmaceutical industry, it is used to make emulsions, ointments, suppositories as well as other remedies.
  2. Propylene glycol stearate is made use of as a W/O type food emulsifier, which has frothing, foam stability and also emulsifying homes. It is often used in cakes to boost its details quantity. my nation specifies that it can be utilized in cakes, and the maximum usage amount is 2.0 g/kg.

Propylene Glycol Stearate Application

Propylene glycol stearate is milky white solid at room temperature. Not soluble or dispersed in water and also glycerin, soluble in propylene glycol, isopropanol and various other solvents when heated up. The hydrophobic part of its molecular structure is leading, thus providing it water-in-oil emulsifying residential or commercial properties. There is no mesocrystal in water. Monopropyl ester exists in a-crystal form, without polymorphism, but has a-crystal tendency or has a tendency to a-crystal kind, as well as can stabilize x-crystal kind of various other emulsifiers, and has good gas-filling residential or commercial properties. These attributes determine its range of application.

1. Cakes: Propylene glycol stearate integrated with monoglyceride and various other emulsifiers is extensively made use of in the production of pastries, especially cakes. For example, 60% of monopropyl ester, 24% of monoglyceride and 15% of lactoylglyceride are mixed as well as made into powder. The cake is mixed with emulsifier, which can make the cake have a substantial renovation in temperature as well as special water ability. At the same time, the cake has soft cells, penalty and also consistent particle structure and also superb eating top quality. Monopropyl ester can also be combined with sucrose ester or sorbic acid ester to make ointment quick-fat cake oil, which can shorten the mixing time. This emulsifier is especially tolerant to the enhancement method. It has great toughness when whipping, mixing and also baking, as well as is utilized to make muffins and sponge cakes. Some residential monopropyl esters are utilized in the prep work of immediate cake oil. Additionally, it can also be prepared as a powder foaming agent, which has solid emulsifying as well as lathering power, as well as can be used in pastry manufacturing.

Liquid shortening as well as light whipping cream: Monopropyl ester is specifically easy to prepare fluid reducing as a result of its strong lipophilicity. Adding 8-10% monopropyl ester to soybean oil and sunflower oil can obtain uniform and also storage-stable shortening including emulsifiers, which can be made use of to prepare breads and also cakes. 9 ~ 12% monopropyl ester is blended with a percentage of monoglyceride as a frothing cream emulsifier.

In addition, monopropyl ester is made use of in soy item defoamer, instantaneous rice, bread, foamed butter, and so on. Normally speaking, propylene glycol stearate is seldom utilized alone, as well as it is usually used in mix with various other emulsifiers. It is used extra in bread as well as reducing, and also its use in other elements is progressively increasing.

Preparation of Propylene Glycol Stearate

Include stearic acid, propylene glycol and a stimulant to a four-neck flask furnished with a stirrer, a thermostat, a brief reflux column and a nitrogen inlet tube. The response was executed at 130-200 ° C for numerous hours under a nitrogen environment. After the response, cool off, counteract, vacuumize, gather unreacted propylene glycol, add a suitable quantity of decolorizing agent to decolorize depending on the deepness of the shade, and after that acquire propylene glycol stearate. The product is a light yellow clear fluid when it melts, and also a milklike white strong at space temperature.
