What is Triglycerol Monostearate?

Tripolyglycerol monostearate (PGFE) HLB worths from 5 to 8 can be set up with O/W and also W/O solutions. As a vital food emulsifier and additive, tripolyglycerol monostearate is extensively made use of in food, pharmaceutical, plastic, textile, cosmetic, detergent and also other industries.

Tripolyglycerol monostearate it is can be used in cakes and also breads with an optimum dosage of 0.1 g/kg as well as ice cream with an optimum dosage of 3.0 g/kg. The majority of the existing manufacturing devices are reasonably complicated, and the advantages as well as downsides of tripolyglycerol monostearate as a dispersant have vital economic importance for improving item top quality as well as reducing the material of byproducts.

Triglycerol Monostearate Uses

  1. Tripolyglycerol monostearate can be utilized as stabilizer, emulsifier, frothing agent.
  2. Tripolyglycerol monostearate can be utilized as W/O type food emulsifier, with good distributing as well as emulsifying impact. It can be utilized in ice cream, popsicle, gelato, vegetable protein beverage as well as lactic acid bacteria drink according to our nation’s regulations. The optimum usage quantity is 10.0 g/kg.
  3. Tripolyglycerol monostearate is made use of in various foods as well as cosmetics as emulsifier, dispersant, lathering representative, defoaming representative and also stabilizer.

Application of Triglycerol Monostearate

1. A medical polyvinyl chloride composite material, consisting of the following components by mass: 56 parts of polyvinyl chloride, 2 parts of tripolyglycerol monostearate, 6 parts of epoxy linseed oil, trimellitic acid 1 part of trioctyl citrate, 5 parts of zinc stearate, 4 parts of polyvinylpyrrolidone, 1 part of silicon dioxide, 4 parts of para-aminobenzoic acid, 13 parts of polyethylene wax, and 5 parts of butyl oleate.


(1) According to the above mass parts, polyvinyl chloride, tripolyglycerol monostearate, trioctyl trimellitate citrate, zinc stearate, polyvinylpyrrolidone, silicon dioxide, p-aminobenzoic acid Add polyethylene wax and polyethylene wax into a mixer, and mix at 90°C with a speed of 500r/min to obtain a mixture 1;

(2) add butyl oleate and epoxy linseed oil to step (1) gained compound one, mix at 200 DEG C of temperature, and speed is 1200/min, obtain compound two;

(3) Extruding the mixture obtained in step (2) through a twin-screw extruder, cooling, drying, and cutting, the temperature of the screw extruder is 260°C.

2. The metal antirust oil of Triglycerol Monostearate, the preparation method comprises the following steps:

(1) Mix 145 rosin resin, No. 120 solvent oil, and fatty alcohol polyoxyethylene ether according to the weight of each raw material required for preparing the composite film-forming material, and stir at a rate of 600 rpm for 40 minutes at 55 °C , then add the remaining raw materials required for the preparation of the composite film-forming material, then heat up to 75 °C, stir at a rate of 600 rpm for 30 minutes, stop heating, and cool to obtain a composite film-forming material;

(2) The raw materials for preparing the metal rust preventive oil containing Triglycerol Monostearate were mixed and stirred at a rate of 350 rpm for 40 minutes at 85°C, stopped stirring, kept for 2 hours, and then cooled.

Preparation of Triglycerol Monostearate

A preparation method of tripolyglycerol monostearate is to prepare by taking glycerol as a raw material:

The specific preparation steps are as follows:

(1) Glycerol polymerization: with alkali as catalyst, at about 260 ℃, under nitrogen protection, glycerol is condensed and dehydrated into triglycerol,

(2) Alcoholization of triglycerol: Using alkali as a catalyst, at about 230°C, under nitrogen protection, triglycerol is directly esterified with stearic acid.

In this preparation process, about 4% of the total amount of water will be generated (that is, the total output of the product will be reduced by about 4%), wherein the water needs to consume energy to remove (it has been removed during the chemical reaction process), In addition, stearic acid is more expensive, thus increasing the production cost. Some manufacturers also use hardened oil and triglycerol as raw materials to prepare tripolyglycerol monostearate, but they still cannot solve the problem of high cost.

Specific preparation method:

(1) Under the pressure of -0.09MPa, mix and heat glycerol and a compound mixed basic catalyst (a mixture of NaOH and NaH2PO2 with a mass ratio of 1:1) that accounts for 0.4% by weight of glycerol to 250° C. After concentrating and dehydrating, the trimerization is obtained. glycerin;

(2) under the pressure of -0.09MPaa, add 10mol tripolyglycerol and 0.1mol compound mixed alkaline catalyst (NaOH and NaH2PO2 mixture with a mass ratio of 1:1) into the reactor, mix evenly, and heat to 60°C;

(3) nitrogen is introduced into the reactor, 6mol of recovered tristearate is added to the tripolyglycerol and compound mixed basic catalyst mixture in step (2), the temperature is raised to 200°C and stirred, and the temperature is lowered after the esterification reaction for 6h, Cool to normal temperature to obtain solid tripolyglycerol monostearate.

During the whole reaction process, nitrogen needs to be replaced continuously.

Advantages of this method:

(1) this method solves the problem that the traditional old process production cost is high for many years, and this method provides the by-product ditriester and triglycerol that are produced when the reclaimed distillation monoglyceride manufacturer produces the distilled monoglyceride as raw materials to prepare trimer Glycerol monostearate, the price of the ditriester used is only about 57% of stearic acid and about 85.7% of hardened oil. This preparation method can effectively reduce the production cost of tripolyglycerol monostearate, The process is simple, the conditions are easy to control, and the high-quality tripolyglycerol monostearate can be industrially produced in large quantities.

(2) this method produces triglycerol monostearate by esterification reaction of triglycerol and ditriester (at high temperature, the method for preparing triglycerol monostearate, using alkali as catalyst, compared with the traditional process, produces about 4% less Water, thereby reducing production energy consumption, in line with the requirements of green environmental protection.

(3) In the reaction process of this method, nitrogen is used as the protective gas and the reducing agent NaH2PO2 or NaH2PO2·H2O in the compound mixed alkaline catalyst is used to effectively prevent the decomposition of saturated fatty acids and darkening of the color at high temperature, and reduce the peculiar smell and odor of the product. .

(4) Tripolyglycerol monostearate and propylene glycol monostearate prepared by this method are compounded to obtain an emulsified composition of this method, and the emulsified composition is applied in cakes, which can obviously improve the quality of cakes, increase the The volume of the cake makes the texture of the cake delicate and soft.
