USP-GRADE PROPYLENE GLYCOL

USP-Grade Propylene Glycol is a synthetic, odorless, and colorless liquid widely used in pharmaceutical formulations. It acts primarily as a solvent, humectant, and preservative, making it essential in various dosage forms like oral liquids, injectables, topical creams, and gels. Its ability to dissolve active ingredients, retain moisture, and stabilize formulations helps enhance the efficacy, stability, and shelf life of medications. Additionally, its non-toxic and generally recognized as safe (GRAS) status allows it to be used in oral and topical pharmaceutical products without adverse effects.
