Glycerol or glycerin is a byproduct in biodiesel manufacturing. The expanding manufacturing of biodiesel worldwide has led to the generation of a considerable amount of glycerol that has become an environmental proposition since glycerol cannot be disposed of without treatment. Effective utilization of glycerol, in consequence, improves the economics of biodiesel production and environmental factors among various glycerol derivatives. Glycerol monostearate (GMS) is one of the most value-added products employed in industrial applications in the food industry, pharmaceutical, and non-ionic surfactants. Thus, glycerol monostearate is a high economic value product and has a bright market prospect in this globalization era. The most commonly used for synthesizing glycerol monostearate is reacted over glycerol and stearic acid using a catalyst. In addition, the influence of relevant reaction parameters on the esterification pathway was discussed, and some suggestions were made for the future work of this research. This critical review provides an essential assessment of the publicly available information published in recent years on the manufacture of glycerol monostearate using various homogeneous, heterogeneous and enzymatic catalysts.
