Usage
Propylene Glycol is a humectant and flavor solvent that is a polyhy- dric alcohol (polyol). it is a clear, viscous liquid with complete solu- bility in water at 20°c and good oil solvency. it functions as a humectant, as do glycerol and sorbitol, in maintaining the desired moisture content and texture in foods such as shredded coconut and icings. it functions as a solvent for flavors and colors that are insoluble in water. it is also used in beverages and candy.
