Polar aprotic solvent - Wikipedia

In chemistry, a protic solvent is a solvent that has a hydrogen atom bound to an oxygen (as in a hydroxyl group −OH), a nitrogen (as in an amine group −NH2 or −NH−), or fluoride (as in hydrogen fluoride). In general terms, any solvent that contains a labile H is called a protic solvent. The molecules of such solvents readily donate protons (H ) to solutes, often via hydrogen bonding. Water is the most common protic solvent. Conversely, polar aprotic solvents cannot donate proto… WebGlycerol-1,2-carbonate can be used in particular in cosmetics and personal care products as a protic solvent with a high Permittivity ε=82.7 and humectant.
