Product Description
Monostearin, alternatively named 1-Stearoyl-rac-glycerol, belongs to the family of long-chain fatty acid glycerides. Formed endogenously within the human organism as a metabolic by-product from fat breakdown, this compound is classified as one of the serum metabolic biomarkers being explored for cancer detection and diagnosis, with special emphasis on ovarian-cancer-related investigations.
Beyond that, monostearin finds application in the creation of state-of-the-art drug delivery systems such as nanoparticles and microemulsions. Furthermore, it acts as a high-performance emulsifier, which contributes to stabilizing active pharmaceutical ingredients and maintaining their suspended state inside biodegradable formulation matrices.

Application Scenarios
Thanks to its outstanding emulsification, dispersion and stabilization capabilities, glycerol monostearate (CAS#123-94-4) finds extensive utilisation across multiple industrial sectors. Within the food sector, it acts as an emulsifying agent that facilitates homogeneous mixing of oil-water phases for margarine, shortening and similar commodities. It also works as a stabilizer to retard the staling of baked foods for an extended shelf-life, and serves as a lubricant during candy production.
For cosmetic formulations including lotions and creams, glycerol monostearate performs the role of an emulsifier. It assists in constructing stable emulsion systems whilst delivering moisturizing and thickening effects. In pharmaceutical fields, this compound is adopted as an excipient for topical creams and ointments; it may also be added into sustained-release preparation systems.
When deployed in plastics-related manufacturing, glycerol monostearate confers antistatic and lubricating attributes. Furthermore, it is applied to textiles to improve fabric softness, water-repellent property and antistatic behaviour. For leather processing, it functions as a fatliquor and softening additive to upgrade the overall quality of finished leather.
