Crude glycerin 56-81-5

Crude glycerin is a viscous, hygroscopic liquid by-product, typically containing impurities such as water, salts, and residual fats. It exhibits good solubility in water and possesses inherent moisturizing properties.

It is mainly used as a raw material in industries such as animal feed additives, biodiesel production, and the manufacturing of industrial-grade glycerin derivatives. It can also be further refined for applications in personal care products like soap, shower gel, and facial cleanser, where it acts as a moisturizing and emollient agent.
