Application Notes

food additives
|
Glyceryl monostearate (GMS) is a multifunctional food additive primarily used as an emulsifier, thickener, and quality improver. It imparts a smooth texture to products such as ice cream and cream, and in baked goods, it improves internal structure, increases volume, and delays aging, thus effectively extending shelf life. Its high-purity forms (such as molecular distillation products) are safe and efficient, making it an ideal emulsifier for producing stable pastes.
|
|
Materials industry
|
In the plastics industry, GMS is commonly used as an antistatic agent and anti-fogging agent, especially in food packaging materials. Furthermore, it provides excellent internal lubrication during resin processing, helping to improve extrusion efficiency and enhance the gloss of the finished product surface.
|
Stability and storage conditions
It is recommended to store at room temperature, avoiding excessively high or low temperatures. A typical room temperature range (15-25 degrees Celsius) is generally suitable. Avoid storing in humid environments to prevent moisture absorption and affecting its quality. Avoid direct sunlight. Ensure the container is tightly sealed to prevent air and moisture from entering. Avoid contact with hazardous substances and ensure a clean and uncontaminated storage environment.
