Description

Glycerol (CAS 56-81-5), also known as E422, is a trihydric alcohol derived from natural fats and oils or produced synthetically as a byproduct of biodiesel manufacturing. It functions as a humectant, solvent, and plasticizer across food, pharmaceutical, personal care, and industrial applications. Pricerine 9091 is a recognized trade grade supplied into cosmetic and personal care markets. In food manufacturing, it retains moisture in baked goods, confectionery, and low-calorie sweetener formulations under the E422 designation.

Pharmaceutical formulators use it as a solvent and carrier in oral syrups, topical creams, and suppository bases where controlled moisture activity is critical. Personal care producers incorporate it into skin creams, serums, and hair conditioners to maintain hydration. In polymer and resin production, it acts as a cross-linking agent in alkyd resins and polyurethane systems. Glycerol is supplied as a clear, viscous liquid, typically at 99.5% or 99.7% purity for high-performance needs.

Established grades include USP, BP, Ph. Eur., and FCC for regulated applications, alongside technical grade for industrial use. These standards ensure the material meets strict safety and quality benchmarks for global distribution. Bulk supply is available in drums, IBCs, and road tankers, with both vegetable-derived and synthetic origin options to meet clean-label or cost requirements. Our logistics network ensures timely delivery for large-scale manufacturing operations.
