Looking for High Purity Glycerine Supplier in India?
Glycerine's one of those ingredients that quietly does more work than people realize. It's in cough syrups, it's in ointments, it's in gel capsules — and most people using those products would never guess it's the same compound underneath. Simple, gentle, and remarkably useful across a huge range of formulations.
Also known as glycerol (CAS 56-81-5), this clear, odorless triol offers exceptional humectant, plasticizing, and solvent capabilities. Its inherent biocompatibility makes it uniquely suited for sensitive administration routes, including oral liquids, topical creams, suppositories, and parenterals where tissue tolerance is critical.
At Alex Pharmachem, we supply premium pharmaceutical-grade Glycerine compliant with USP monographs. Whether you are formulating palatability-enhanced syrups or stabilizing gelatin capsule shells, our Ankleshwar-based supply guarantees low impurity profiles, high clarity, and reliable global delivery.
General Information
CAS No. of glycerine, which is also known as glycerol, is 56-81-5. The chemical formula of glycerine is C₃H₈O₃. Glycerine can be described as a clear, colorless, and viscous liquid with no smell but slightly sweet taste. Glycerine is soluble in water, alcohol, and some other organic solvents.
The reasons why glycerine plays such an important role in the pharmaceutical industry may be explained by the fact that glycerine has very specific properties that are rather difficult to combine in one substance. Such properties include non-toxicity, biodegradability, high boiling point, and biocompatibility, which means that the substance does not affect blood and tissues. That biocompatibility is a big deal. It's part of why glycerine shows up in injectable preparations and topical formulations alike, situations where a harsher solvent simply wouldn't be an option.
In practice, it functions as a solvent, humectant, and lubricant across oral medications, cough syrups, suppositories, and topical formulations. It also acts as an excipient — improving palatability and stability in finished products, which matters more than people tend to appreciate until they've tasted a poorly formulated syrup.
Pharma-grade glycerine is manufactured to USP standards, requiring a purity level with essentially no hazardous contaminants — a meaningfully different bar than the technical-grade material used in industrial lubrication or coatings.
Applications
Glycerine provides versatile solvent, humectant, and biocompatible formulation support:
Solvent and carrying agent
Solvent and carrying agent duty is probably glycerine's most common pharma role — helping dissolve and deliver active ingredients in liquid formulations like cough syrups and oral medications.
Humectant for topicals & ointments
Additionally, glycerin acts as a humectant, holding and absorbing moisture, which gives it an advantage when used in topical ointments and products for skin contact.
Lubricant & excipient in gel capsules
Apart from that, glycerin acts as a lubricant in gel capsules and suppositories, as well as in general as an excipient, providing improved taste, feel, and stability of the product.
Injectable solution biocompatible solvent
Its biocompatibility is also useful in preparing injectable solutions, where aggressive solvents cannot be used at all.
