Polyglycerin-3
What is Polyglycerin-3?
Polyglycerin-3 is a synthetic, water-soluble polyol created by linking three glycerin molecules through ether bonds in a polyglycerization process. This branched polymer structure gives it strong hygroscopic properties, allowing it to absorb and hold water effectively. Primarily used in leave-on and rinse-off skincare like moisturizers, serums, toners, cleansers, and hair products, it functions by drawing atmospheric moisture into the skin's outer layer and preventing water loss. Its viscous, colorless nature makes it ideal for improving texture and stability in formulations. With a low molecular weight, it aids mild penetration while remaining gentle, often selected for everyday hydration needs across product types.
