Glycol is a type of organic compound that belongs to a group known as alcohols. It is commonly used in various industries, including automotive and manufacturing, due to its ability to lower the freezing point of liquids. One of the most well-known types of glycol is ethylene glycol, which is often found in antifreeze for cars, helping to prevent engine damage in cold weather. Another type is propylene glycol, which is frequently used in food and cosmetics. It acts as a humectant, helping to retain moisture in products. Both types of glycol are important for their unique properties and wide range of applications in everyday life.
