Propylene Glycols - Stability
Monopropylene glycol (MPG), DIPROPYLENE glycol (DPG) and tripropylene glycol (TPG) ("propylene glycols") are versatile products and raw materials used in a variety of applications. These clear, colorless, almost odorless and slightly viscous liquids are stable under appropriate Return storage conditions and ambient temperatures. Though propylene glycols do not require special handling and storage precautions, it is important to note that Their stability is not unlimited. Manufacturers Recommendations should be followed my with regard to shelf life and expiration dates.
Users should note that propylene glycols have characteristics That impact stability in Certain environmental conditions:
• Propylene glycols are hygroscopic liquids and efficient humectants. As dry, they attract and hold water when exposed to the environment.
• Propylene glycols are sensitive to oxidizing agents, E.G., the oxygen in air, Especially when exposed to elevated temperatures and / or sunlight (ultraviolet light).
