Refined Vegetable Glycerin (Glycerol) in Bulk
Refined glycerin (glycerol, CAS 56-81-5) is a clear, odourless, sweet-tasting liquid that attracts and holds moisture. Vegetable glycerin is made from plant oils such as palm, coconut or soybean oil, often as a co-product of biodiesel and oleochemical production, and refined to a high purity. It is one of the most widely used humectants and solvents in personal care, pharmaceutical, food and industrial products.
Cavin Resources supplies bulk refined vegetable glycerin to cosmetic, soap, pharmaceutical, food and chemical manufacturers worldwide.
Applications of refined glycerin
- Cosmetics and personal care – moisturisers, lotions, toothpaste, shampoos and soaps.
- Pharmaceuticals – syrups, cough medicines, capsules and topical products (USP grade).
- Food and beverage – humectant, sweetener and solvent for flavours (food grade).
- Industrial chemicals – alkyd resins, polyether polyols and antifreeze blends.
- Tobacco and e-liquids – humectant (appropriate grade required).

Refined vs. USP glycerin
Standard refined glycerin suits most industrial and cosmetic uses. USP/EP grade meets pharmacopoeia standards for pharmaceutical and food use and trades at a higher price. Tell us your end use and required standard.
Storage
Glycerin is hygroscopic, so store it in sealed containers in a cool, dry place. It is stable and has a long shelf life when kept closed.
Glycerin pricing is closely tied to biodiesel-linked feedstock supply and varies meaningfully by region and purity grade – USP/pharma-grade material commonly trades well above standard refined grade. Request a firm quote for your required specification.
Frequently asked questions
Is glycerin the same as glycerol?
Yes. Glycerol is the chemical name; glycerin (or glycerine) is the commercial name for the refined product.
Is vegetable glycerin suitable for vegan products?
Vegetable glycerin is plant-derived. Ask us for the source and documentation if you need specific certifications.
