Glycerin Drum Food Grade

Whatsapp Order

Glycerin Drum Food Grade, also known as glycerol, is a colorless, odorless, viscous liquid with a sweet taste and hygroscopic properties. It is a trihydroxy alcohol (triol) used extensively across food, pharmaceutical, cosmetic, and industrial applications. Food-grade glycerin is produced through hydrolysis, saponification, or transesterification of fats and oils, ensuring compliance with stringent purity standards. It is supplied in bulk (e.g., 250kg drums) for large-scale applications where non-toxic, biodegradable humectants or solvents are required. Glycerin is widely appreciated for its moisture-retaining ability, solubility, lubricity, and stabilizing properties.

Glycerin Drum Food Grade

Primary Uses

Food Industry

Humectant in baked goods, candies, icings, and nutrition bars to retain moisture and softness.
Solvent and carrier for flavors, colors, and preservatives.
Sweetener substitute in sugar-free and low-carb foods due to its mild sweetness (~60–70% as sweet as sucrose).
Cryoprotectant for frozen desserts and food preservation.
Thickening agent in sauces, beverages, and syrups.
Emulsifier and plasticizer in food coatings and films.
Preservative in herbal tinctures, extracts, and glycerites.

Pharmaceutical & Nutraceutical Industry

Excipient in oral, topical, and injectable formulations.
Base for cough syrups, lozenges, and elixirs.
Laxative agent (especially in suppositories and enemas) due to its osmotic action.
Soft gelatin capsule filling for vitamins and supplements.
Topical base for creams, gels, and ointments due to its skin-hydrating properties.
Used in tinctures, herbal extracts, and liquid dietary supplements.

Cosmetics & Personal Care

Moisturizer and humectant in skin creams, lotions, shampoos, and conditioners.
Hydration enhancer for lip balms, face masks, and serums.
Soothing agent in aftershaves, shaving creams, and soaps.
Clear base for hand sanitizers, body mists, and toners.
Enhances spreadability and texture of formulations.

Tobacco Industry

Humectant and plasticizer in cigarettes and smokeless tobacco to maintain product moisture and flavor.
Used in e-liquid formulations for vaping (with PG or on its own) to produce vapor and carry flavor.

Chemical & Industrial Applications

Plasticizer in biodegradable plastics, glues, and resins.
Antifreeze component in food-safe or pharmaceutical-grade systems.
Lubricant and softener in textile, paper, and leather processing.
Intermediate in chemical synthesis of epichlorohydrin, nitroglycerin, and polyols.
Humectant in printing inks and adhesives.

Secondary Uses

Veterinary & Animal Nutrition

Energy source and additive in livestock feed formulations.
Used in oral medications and topical treatments for pets and livestock.

Agriculture

Soil conditioning agent to retain moisture in drought-prone areas.
Biocompatible carrier for pesticides, herbicides, and foliar sprays.

Laboratory & Biotech

Cryoprotectant for cells and biological samples in low-temperature storage.
Used in gel electrophoresis as a density medium.

Paints and Coatings

Acts as a plasticizer and flow enhancer in water-based paints and coatings.
Improves gloss, flexibility, and drying time.
