What is Glycerin Monostearate?
Glycerin monostearate (GMS) is an organic compound obtained by the reaction of glycerin with fatty acids, especially stearic acid. This substance belongs to the group of nonionic emulsifiers and appears as a white or cream-colored powder at room temperature, without a specific odor or taste. GMS is one of the most common additives in various industries due to its emulsifying, anti-crystallization, stabilizing, and viscosity-increasing properties.
Glycerin Monostearate Applications in the Food Industry
- Emulsification: Stabilizing oil-in-water emulsions or vice versa in products such as ice cream, margarine, sauces, and dairy products.
- Foam stabilization: In foamed beverages and aerated desserts, GMS increases foam stability and prevents settling.
- Bread staling prevention: By modifying the gluten structure and affecting moisture retention, GMS increases the softness, freshness, and shelf life of bread and baked goods.
- Texture and appearance improvement: The use of GMS leads to uniformity in the texture and appearance of food products.
- Anti-caking agent: In some processed foods such as chewing gum or sweets, GMS prevents components from sticking to each other.
Role of Glycerin Monostearate in the pharmaceutical industry
Pharmaceutical companies use GMS in a wide range of products because of its unique physicochemical properties.
- Emulsifier in topical formulations: Creams, lotions, and ointments use GMS to achieve the right consistency and better absorption.
- Opaque agent and viscosity enhancer: In semi-solid products such as pharmaceutical gels, it improves the appearance and feel when used.
- Drug release control: In some controlled formulations, GMS acts as a lipophilic carrier in the drug matrix and plays a role in controlling the release of active ingredients.
- Stabilizer in tablets and capsules: Helps reduce adhesion and improve compression in tableting.
Other applications: Cosmetics and health industries
1. Creams and lotions: As an emulsifier and enhancer of consistency and stability
2. Hair care products: To create a uniform texture and more shine
3. Sunscreen formulas: As a suitable base for stabilizing UV compounds
GMS safety benefits and features
• Safe and non-toxic:.Researchers recognize GMS as safe for human consumption and report that it does not cause any acute or chronic toxicity at approved doses.
• Internationally approved:. Approved by reputable organizations such as FDA (US Food and Drug Administration), EFSA (European Food Safety Authority) and JECFA.
• Environmentally friendly:. GMS is biodegradable and can also be used in environmentally friendly products.
• Suitable for plant-based formulations (Vegan):. Since it can also be produced from plant sources, it is suitable for vegan products.
