Products Description of Monostearin CAS#123-94-4
Monostearin, also known as 1-Stearoyl-rac-glycerol, is a long-chain fatty acid glyceride that naturally occurs in the body as a metabolic by-product of fat degradation. It is recognized as one of the serum metabolic biomarkers studied for the detection and diagnosis of cancers, particularly ovarian cancer.
Monostearin is also utilized in the development of advanced drug delivery systems, including nanoparticles and microemulsions. In addition, it functions as an effective emulsifying agent, helping to stabilize pharmaceutical compounds and enable their suspension in biodegradable formulations.

Product Usage
Glycerol monostearate (CAS#123-94-4) is widely applied in various industries due to its excellent emulsifying, dispersing, and stabilizing properties. In the food industry, it is used as an emulsifier to promote the uniform blending of oil and water in products such as margarine and shortening. It also functions as a stabilizer to slow down the staling process of baked goods and extend shelf life, as well as a lubricant in candy manufacturing.
In the cosmetics industry, glycerol monostearate serves as an emulsifier in formulations such as lotions and creams, helping to create stable emulsion systems while providing moisturizing and thickening benefits. In pharmaceutical applications, it is used as an excipient for creams and ointments and can also be incorporated into sustained-release formulations.
In the plastics industry, glycerol monostearate provides antistatic and lubricating effects. Additionally, it is utilized in the textile industry to enhance fabric softness, water resistance, and antistatic performance, while in leather processing, it acts as a fatliquoring and softening agent to improve leather quality.
