Solvent & Carrier
Solvent for various active ingredients in oral liquids and elixirs, ensuring uniform dosage
Osmotic Laxative
API in rectal suppositories to treat constipation by drawing water into the bowel
Cough & Cold
Soothing "demulcent" effect in cough syrups, coating the throat to reduce irritation
Moisturizing Agent
Humectant-prevents skin dryness by drawing water into the stratum corneum
Oral Care
Primary ingredient in toothpaste to maintain consistency, prevent drying out, and provide a sweet taste without promoting tooth decay
Hair Care
Added to conditioners and serums to improve hair elasticity and moisture retention
Humectant & Thickener
Keeps baked goods moist and provides "body" to low-fat food products
Solvent for Flavors
Used to carry concentrated flavorings and food colors
Sweetener
Provides sweetness with a lower glycemic index than sucrose
Alkyd Resins (Elemental Derivatives)
KSM: Manufacture of paints and coatings Antifreeze & Coolants: Specialized heat transfer fluids where non-toxicity is required Epichlorohydrin Intermediate: "Glycerin-to-ECH" route for green epoxy resin production

Refined Glycerine: The Universal Humectant

In cosmetics and pharma, "Gold Standard" for moisture retention. It draws water from the environment into the skin (humectancy) and prevents the drying out of topical creams and oral cough syrups. It also acts as a non-toxic solvent for botanical extracts

Crude Glycerine: Energy & Industrial Feedstock

High-energy co-product often used in biogas plants to boost methane yield. In the agricultural sector, refined into a high-calorie animal feed supplement. Industrially, serves as a precursor for the production of Epichlorohydrin (for epoxy resins) and Propylene Glycol via hydrogenolysis

Food & Nutrition: E422 Additive

Solvent for flavors, a filler in low-fat food products, and a softening agent in marshmallows and candies to maintain moisture and prevent crystallization of sugar
