Polyglyceryl
Polyglyceryl refers to a family of non-ionic surfactants and emulsifiers made by the polymerization of glycerol units. Depending on the number of glycerol units (e.g., Polyglyceryl-2, -3, -6, -10) and fatty acid esterification (e.g., laurate, oleate, stearate), they offer different emulsifying and solubilizing properties. These compounds are biodegradable, mild, and skin-friendly, making them ideal for use in cosmetics, food, pharmaceuticals, and personal care products. Polyglyceryl esters are often chosen in natural and organic product formulations due to their origin and non-toxic profile.
