About Glycerin

Glycerin also known as Glycerol, is a high-purity, multifunctional trihydroxy alcohol that serves as a foundational "building block" across the life sciences and industrial sectors. Primarily derived as a co-product of oleochemical processing (fatty acid and biodiesel production), a viscous liquid recognised for its ex...

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
