Food Grade Vegetable Glycerin: Uses, Benefits and Safety

How It’s Made

The most common method is saponification, where plant oils like coconut, soy, or palm are broken down with an alkali. The crude glycerin is then purified by distillation to achieve food-grade quality. This ensures safety for direct use in food and personal care products.
