1. Product Introduction & Main Application
Arnico’s Mono Propylene Glycol (MPG) is a clear, odorless, high-purity liquid that, due to its hygroscopic characteristics, low viscosity, and very low toxicity level (GRAS by FDA), is used in a wide range of food, pharmaceutical, and industrial applications. This substance is an ideal carrier, safe antifreeze, and excellent humectant in modern formulations.
