Applications
- Food Industry: Glyceryl monostearate is one of the most important functional additives, widely used in the production of products such as bread, cakes, and biscuits. In the dairy and cold beverage industries, it plays a key role in emulsification, stabilization, and crystallization prevention. In the confectionery and chocolate industries, it is primarily used as an anti-crystallization agent and emulsion stabilizer. In meat processing, glyceryl monostearate is primarily used in chopped meat products such as luncheon meat and ham, at a dosage of 1-5% of the fat content. It can increase fat content, address quality issues caused by fat precipitation, and reduce production costs. It also inhibits water extraction, shrinkage, and hardening in finished products, extending shelf life.
- Cosmetics and Personal Care Products: In the skincare industry, glyceryl monostearate is one of the most widely used ingredients, primarily performing three functions: emulsification, moisturization, and emollients. As an emulsifier, glyceryl monostearate plays a key role in products such as creams, lotions, and serums. As a humectant, glyceryl monostearate works through multiple mechanisms. Its molecular structure contains multiple hydroxyl groups, making it hydrophilic. It absorbs moisture from the air and transports it to the stratum corneum, thereby increasing skin hydration. As an emollient, glyceryl monostearate fills tiny pits and cracks on the skin’s surface, smoothing and improving its texture. In sunscreen products, glyceryl monostearate not only acts as an emulsifier to ensure uniform mixing of the formula but also forms a protective layer on the skin, enhancing its effectiveness.
- Plastics Industry: In the plastics industry, glyceryl monostearate is primarily used as an internal lubricant, antistatic agent, and antifogging agent. In plastic foam products, glyceryl monostearate plays a unique role as a foaming aid and anti-shrinkage agent.
- It is also used in other smaller applications, such as the pharmaceutical, textile, and coatings industries, where it demonstrates its unique effectiveness.
Tree Chem have been deeply engaged in the application of glyceryl monostearate (GMS, CAS 123-94-4) for many years, and have established in-depth cooperation with leading companies in various industries such as food, cosmetics, and plastics, accumulating rich experience in industry implementation. Taking the food industry as an example, we have helped several baking companies solve the core pain point of bread staling – the problem of their products hardening after one day of storage. Through precise analysis of flour characteristics, we optimized the GMS addition ratio from 0.3% to 0.45%, and designed a supporting compounding solution. Ultimately, the solution achieved the dual effects of extending the shelf life of bread by 48 hours and increasing its volume by 12%. This solution was subsequently adopted and applied across the company’s entire production line.
