Beschreibung

General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of the 12 Principles of Green Chemistry. Glycerol, with its high boiling point, low flammability, and polarity, is a standout choice. As a non-toxic and biodegradable compound, it aligns perfectly with the principles of ′Safer Solvents and Auxiliaries′ and ′Design for Degradation′. Click here for more information.
