Glycereth-12

What is Glycereth-12?

Glycereth-12 is a polyethylene glycol ether derived from glycerin, featuring an average of 12 ethylene oxide units attached to the glycerol backbone. This creates a water-soluble, hydrophilic compound commonly found in moisturizers, serums, cleansers, and hair care products. As a humectant, it binds water molecules from the environment or deeper skin layers, promoting retention in the upper skin layers to support suppleness. Simultaneously, it acts as a viscosity controller by influencing the flow and consistency of formulations, enabling better spreadability and stability without greasiness. Its clear, odorless nature makes it versatile for leave-on and rinse-off items, aiding in even distribution of active ingredients while maintaining a lightweight feel on skin and hair.
