What is Glyceryl Monostearate?

Molecular Formula (Glyceryl Monostearate): C21H42O4

Molecular Weight: 358.60 g/mol

Chemical Name: Glycerol Monostearate

CAS Number: 123-94-4

Glyceryl Monostearate, used as an emulsifier in the food industry, is generally referred to by the short name GMS. It is an ester formed by 2 different chemical compounds. These 2 chemical compounds are Stearic Acid and Glycerin.

It is commercially specified as glycerin monostearate. It decomposes when it comes into contact with surfactants.

It is an ester derivative obtained from renewable sources. It is a mixture of long-chain stearic acid and monoglyceride.

E Code= E471

Other Names Are As Follows;

• Glycerin Monostearate
• 1-Monostearin
• Monoglyceride
• Stearic acid 1-monoglyceride
• Glyceryl 1-stearate
• Monoglyceryl Stearate
• Glyceryl 1-octadecanoate

How is Glyceryl Monostearate Produced?

Glycerin raw material is obtained by reacting it with triglycerides produced from animal and vegetable sources. As a result of this reaction, a mixture of mono and diglycerides is produced.

Since the raw materials used in the production of Glyceryl Monostearate are not pure, a mixture of different ester chemical substances such as oleate and palmitate is produced as a result of the reaction.

What are the Physical and Chemical Properties?

In terms of physical appearance, it has a slightly fatty odor. It is in solid form with a white or pale yellow color.

Melting Point is 74 °C.

Boiling Point: No information available.

In terms of solubility, it does not dissolve in water. It dissolves in hot ethyl alcohol and hot oils. It also has the ability to dissolve in hot organic solvents.

Soap or a surfactant must be added for it to be dispersible in water.

The pH of GMS is in the range of 6.0-7.0.

Its density is in the range of 0.95-0.96 g/cm3 at 21 °C.

It has outstanding thermal and oxidative stability.

What are the Usage Areas of Glyceryl Monostearate?

• It has solvent properties that allow the dissolution of oil-in-water and water-in-oil. It provides stabilization of products in such applications.
• Glyceryl monostearate ester produced from soybean oil is used in the food and cosmetic industries.
• It is used as an emulsifier in the manufacture of skin-lightening products in the cosmetic sector. In this application, Mono Propylene Glycol is used as a moisturizer and solvent, and Edta is used as a chelating agent.
• GMS acts as a surfactant in the food industry and some applications.
• It is used as a lubricant and release agent in confectionery.
• GMS 90 (Glycerol Monostearate) is used in halva production to prevent oil separation. In this way, oil separation from halva or tahini is minimized under storage conditions.
• Glycerin Monostearate is used as a dough softening agent.
• It is used as a lubricant in the treatment of acne and pimples on the skin.
• It is used as an emulsifier in food products.
• It is used in dairy products and bakery products to make the mixture more stable. That is, it is used to ensure the mixing of phases with each other.
• Glycerin Monostearate is used to reduce moisture content in starch production.
• It is used in pharmaceutical production to emulsify water and oil mixtures. It acts as an emulsifier in this field.
• It is used in the manufacture of cosmetic creams and dermatology products. In dermatology products, it is used together with Vitamin E to obtain a coating material.
• It is used in the water phase together with stearic acid in the manufacture of moisturizing creams.
• Glyceryl Monostearate is used in baked goods to improve dough quality and to stabilize fat and protein emulsions.
• Glycerin Monostearate (GMS 90) needs to be mixed with a certain amount of lecithin to increase its solubility in bread production. Using too much lecithin can change the properties of the finished product. Therefore, attention should be paid to these ratios.
• In the production of emulsions manufactured to soften the fabric texture of textile fabrics, it is used together with nonionic surfactants and fatty alcohols to stabilize the emulsion and ensure viscosity stability.
• In the plastics industry, it is used to increase surface smoothness and facilitate the processing of plastic materials. In addition, it increases the processability of the material that will form the plastic by providing flexibility.

What are the Factors Affecting Their Prices?

The price of Glyceryl Monostearate is directly dependent on the prices of the raw materials used in its production. As stearic acid and glycerin prices increase, the price of GMS will increase.

Glycerin Monostearate prices are directly dependent on the stocks of the companies selling this chemical. As stocks increase, prices will experience a short-term decrease.

The price of Glyceryl Monostearate depends on the usage areas of this chemical. As the usage areas of GMS expand, prices will increase.
