Ethylene Glycol vs. Glycerol: What's the Difference?
Ethylene glycol is a toxic organic compound used in antifreeze, while glycerol is a non-toxic compound used in food, pharmaceuticals, and cosmetics.
Ethylene glycol, a diol, is primarily used in antifreeze and coolant formulations due to its low freezing point. Glycerol, a triol, is known for its hygroscopic nature and is widely used in food, pharmaceuticals, and cosmetic products for moisture retention.
The toxicity of ethylene glycol makes it hazardous for human consumption, often requiring careful handling. In contrast, glycerol is non-toxic and safe for use in various consumer products, including food items and skin-care products.
Ethylene glycol is utilized in industrial applications, such as in the production of polyester fibers and resins. Glycerol finds use in medical and personal care products due to its skin-friendly properties and as a sweetener in food products.
In terms of physical properties, ethylene glycol is a colorless, odorless liquid with a sweet taste, which contributes to its hazardous nature if ingested. Glycerol, also colorless and odorless, is recognized for its viscosity and sweet taste, making it suitable for culinary uses.
Environmental impact is another consideration, as ethylene glycol can be harmful to the environment if not disposed of properly. Glycerol, being biodegradable and non-toxic, poses less environmental risk.
