USP-grade glycerin is a high-purity, vegetable-derived ingredient that serves multiple roles in formulation. It functions as a compatibilizer and bonding agent in personal care products, enhancing ingredient cohesion and skin feel. In industrial applications, it acts as a chemical intermediate in the production of polyesters, polyurethanes, and resins, contributing to improved flexibility, moisture retention, and structural integrity. Its non-toxic, biodegradable nature also makes it ideal for clean-label and sustainable formulations.
