Glycerin water activity
WebMethods: First, water-humectants mixtures were considered. The influence of glycol and glycerin content, glycol chemical structure, glycerin purity and formulation process on the water activity of the binary mixture was studied. Molecular modelling was performed for a better understanding of the impact of glycol chemistry. WebGlycerin, propylene glycol, and PEG-400 are used instead of water in anhydrous nanoemulsions.
