GLYCEROL MONOSTEARATE RSPO

Origin

Glycerol Monostearate RSPO (GMS) is a vegetable-derived emulsifier and emollient obtained from RSPO-certified sustainable palm or coconut oil. It is produced through the esterification of glycerin and stearic acid, resulting in a monoester of glycerol with excellent emulsifying and stabilizing properties. The RSPO certification ensures that all raw materials come from sustainably and ethically managed sources, supporting environmental conservation and traceable palm production.

Summary

Glycerol Monostearate RSPO is a versatile non-ionic emulsifier and thickener widely used in skincare, haircare, and personal care formulations. It provides creaminess, improved texture, and emulsion stability, while also acting as an emollient that enhances skin softness. Due to its natural origin, mildness, and compatibility, it is frequently used in natural and clean-label formulations to support stable Oil-in-Water (O/W) and Water-in-Oil (W/O) emulsions. Its RSPO certification underscores its alignment with sustainable and eco-conscious product standards.
