What are the main uses of Glycerin in pharmaceutical formulations?
Glycerin is used across a wide range of pharmaceutical applications: as a humectant and moisturiser in topical creams and gels (5–30%), as a co-solvent in oral liquids (up to 50%), as a plasticiser in HPMC and gelatin film coatings (10–30% of polymer weight), as a suppository base component, as a laxative active ingredient at high concentrations (glycerin suppositories), and as a sweetening and preservative agent in oral syrups.
What is the difference between Glycerin 99.5% and Glycerin 98% USP?
USP Glycerin requires a minimum assay of 99.0% for pharmaceutical use. 99.5% grade is a higher purity specification sometimes required for injectable or ophthalmic preparations. 98% grade, while commercially available, does not meet USP compendial specification and should not be used in pharmaceutical formulations. Always request a COA confirming the assay value and pharmacopoeial compliance for your application.
Is pharmaceutical grade Glycerin derived from plant or petroleum sources?
Pharmaceutical Glycerin is predominantly produced as a by-product of vegetable oil biodiesel production (plant-derived/natural) or soap manufacture. Synthetic Glycerin derived from petrochemical propylene is also available. For halal, kosher, or natural/organic certified formulations, vegetable-sourced Glycerin must be specified. Please specify source preference when ordering as documentation (halal certificate, non-GMO certificate) can be provided.
Can Glycerin be used in injectable pharmaceutical formulations?
Yes. Glycerin is an approved co-solvent in parenteral formulations. It is used in intravenous preparations at concentrations up to 2.5% and in intramuscular injections at higher concentrations. Injectable-grade Glycerin must meet additional requirements for bacterial endotoxins (LAL test) and particulate matter. Our USP-grade Glycerin is suitable for formulations requiring parenteral co-solvent application.
