What is glyceryl monostearate?

Glyceryl monostearate (Glycerol monostearate, MG) is a natural particle used as an emulsifier with a molecular formula of C21H42O4.

It has two configurations, 1-MG and 2-MG. According to the names of the main constituent fatty acids, monoglycerides can be divided into glyceryl monostearate, glyceryl monolaurate, and glyceryl monooleate, among which glyceryl monostearate is the most widely used.

Because its structure has one lipophilic long-chain alkyl group and two hydrophilic hydroxyl groups, it has excellent surface activity. It can be emulsifying, spreading, defoaming, anti-starch aging, etc. It is the most widely used emulsifier in food and cosmetics.

Glyceryl monostearate is a white or light yellow waxy solid at area temperature, odorless and also unsavory. It is soluble in warm organic solvents such as ethanol, benzene, acetone, mineral oil, fatty oil, etc. It is insoluble in water. However, it can be dispersed in hot water to develop a solution under solid mixing.

Properties of glyceryl monostearate:

  1. Sensory characteristics: glyceryl monostearate (GMS) are related to oils, and their sensory characteristics are similar to those of oils. Its consistency is related to fatty acid groups. Generally, it can be oily, fat or waxy. The color and odor of monoglycerides are related to the corresponding fatty acid groups and the source of the raw materials. The odor of monoglycerides generally has the odor of grease, and the color ranges from brown to milky white.
  2. Thermal stability: Monoglyceride is a mixture of 1-monoglyceride and 2-monoglyceride. This is the result of intramolecular acyl transfer. The activation energy of this intramolecular acyl transfer is relatively low, so in any Under temperature conditions, monoglycerides are a mixture of the two, but the ratio of the two varies with temperature.
  3. Crystallization behavior: As a lipid compound, glyceryl monostearate (GMS) has the phenomenon of homogeneity and polymorphism. Distilled monoglycerides will crystallize into a metastable α-crystalline form, and then into a stable β-crystalline form with a higher melting point. Metastable β’-crystalline form does not exist in industrial monoglycerides. When the α-crystalline form cools down, a solid-state transformation of the third crystalline form occurs, called sub-α.
  4. Mesogenic properties: The monoglyceride and water can interact very complicatedly, and its degree of action depends on the temperature and the ratio of monoglyceride to water, and is also related to the type of fatty acid. The formed material can simultaneously exhibit crystalline properties and liquid properties, that is, mesomorphism.
    The mesogenic phases of monoglycerides include: lamellar mesophase (lamellar phase), α-gel, cubic phase, and hexagonal phases. glyceryl monostearate (GMS) are β-crystals at room temperature and are a lipid bilayer structure. , The middle is connected by hydrogen bonds by polar groups. This layer has a strong affinity for water. When the temperature is higher than the Kraff point, water begins to penetrate into the polar layer of the bilayer to form a layered mesophase.


Glyceryl monostearate is an important emulsification raw product utilized in cosmetics. Additionally, it is extensively used in food, medication, plastic processing, and other areas.

  1. In beverages as well as food:
    • Glyceryl monostearate is commonly used in ice cream, substance milk, veggie protein drinks, bread, cakes, toffee, meat products, and rice flour products. Utilized as an emulsifier, stabilizer, starch anti-aging representative, and so on.
    • Regarding applications as a preservative, bread, biscuits, cakes, and so on are used in the most significant quantity, followed by whipped cream, butter, and gelato.
    • It is made as a bread softener in food processing, defoaming soy items, emulsifier, and stabilizer in dairy products, margarine, and cakes.
    • Glyceryl monostearate can be made use of in food as well as pharmaceutical fungicides. It has anti-bacterial solid activity and also a broad anti-bacterial spectrum. It can be used to preserve meat items, milk items, beer, soy sauce, etc. Fresh.
    • It can form a complex with starch and healthy protein to lower the anti-bacterial effect and is virtually ineffective against Gram-negative bacteria. Yet, it has a good result when combined with other fungicides such as potassium sorbate. Therefore, it is primarily used in substance solutions as an emulsifier, co-emulsifier, stabilizer, and chemical.
  2. Medicinal usage
    • Glyceryl monostearate is used as an excipient in pharmaceutical products for the prep work of neutral lotions. Daily chemicals are used to develop vanishing lotion, ice lotion, hazelnut oil, and so on.
    • It is likewise used in the prep work of aesthetic ointments, lotions, creams, suppository bases, and drug carriers in the pharmaceutical market.
    • It is a suitable raw product for lotion products and resources for preparing neutral ointments.
    • Glycerol monostearate is commonly used in lotion, ointment, and lotion to improve the dispersibility and security of the spread phase.
  3. Edible oils as well as fine chemicals:
    • Margarine, reducing, powdered oil, fresh lotion, fruit stick film, defoamer, and other fields.
    • The surface area acts as a cost emulsifier and also dispersant.
    • Glyceryl monostearate can be used as an emulsifier for industrial silk oils and a lubricating substance for fabrics.
  4. In the handling of pearl cotton, PVC, and also various other plastics and plastic ingredients:
    • Glyceryl monostearate is a commonly utilized non-toxic plasticizer and anti-aging representative, which can effectively boost the softness, plasticity, and antistatic homes of items. Such as food packaging (film), electrical product packaging, sanitary materials, etc.
    • Made use of as trickling representative and anti-fogging agent in plastic film. Used as a lubricant and also antistatic representative in plastic processing.
  5. Other uses:
    • Glyceryl monostearate is also used as a solvent for oils and waxes, hygroscopic powder protectant, and opaque sunscreen.
    • The fat glycerol esters generated by the reaction of glycerol and fats include monoesters, diesters, and triesters. Triesters are oils and also fats and also have no emulsifying ability whatsoever. Typically, a mix of monoester and diester can be used, and an item with a monoester web content of about 90% can likewise be acquired by purification and purification.
    • The fatty acid utilized can be stearic acid, palmitic acid, myristic acid, oleic acid, linoleic acid, and so on. Nevertheless, combined fatty acids having stearic acid as the primary component are used frequently.
