Overview

Hydroxypropyl methylcellulose is a nonionic, water-soluble, viscosity controlling agent. Nonionic indicates that this compound carries no chemical charge, which is important for making it compatible with all types of surfactants. Therefore, it is commonly used in skin cleansing products to thicken the consistency without negative interaction with the other ingredients.

Hydroxypropyl methylcellulose also functions as an emulsion stabilizing agent and a binding agent, in that it increases the viscosity and makes it difficult for the product to destabilize or separate.

This off-white powder can also form films in skincare products, which helps protect the other ingredients from being rinsed away too easily.
