Read the FAQ explanation of Comprehensible InputReal Context
Glycerol, also called glycerin, is a colorless, odorless liquid with a slightly sweet taste that remains stable under heat. It is derived from fats and oils and is commonly produced commercially from triglycerides. In food, it acts as a humectant to retain moisture, as a solvent for flavor compounds, and as a sweetener in small amounts. In cosmetics and pharmaceuticals, it helps keep products smooth, soft, and less sticky. It is widely considered safe for consumption and topical use when used at regulated levels. The term stems from Greek glykos meaning sweet, and the -ol ending signals its alcohol structure.
Usage Reminders
- 1) Glycerol is a humectant, not a sugar.
- 2) In foods it helps retain moisture.
- 3) In cosmetics it improves texture, but use is regulated.
- 4) It can act as a solvent for flavors.
- 5) The spelling glycerol vs glycerin varies by region.
