Application
Polyglycerine serves as a versatile humectant, effectively retaining moisture much like glycerol due to its ability to dissolve in water, alcohol, and other polar solvents. Comprising various mixtures of glycerol ethers, its range spans from diglycerol to higher molecular weight forms like hexaglycerol, allowing for varied applications depending on the desired properties. With a progressively increasing molecular weight and boiling point, polyglycerine balances its moisture-attracting capabilities with elevated stability. Combustible in nature, it is often utilized in formulations that require consistent viscosity and enhanced hydration properties.
