What is propylene glycol other names?
Other names for propylene glycol are 1,2-dihydroxypropane, 1,2-propanediol, methyl glycol, and trimethyl glycol. Propylene glycol is clear, colorless, slightly syrupy liquid at room temperature. It may exist in air in the vapor form, although propylene glycol must be heated or briskly shaken to produce a vapor.
What is glycol in chemistry?
glycol, any of a class of organic compounds belonging to the alcohol family; in the molecule of a glycol, two hydroxyl (―OH) groups are attached to different carbon atoms. The term is often applied to the simplest member of the class, ethylene glycol.

Why is glycol and water mixture?
Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics.
What is glycerol glycol?
Alcohols with two OH groups on adjacent carbon atoms are commonly known as glycols. Commonly called glycerol or glycerin, 1,2,3-propanetriol is the most important trihydroxy alcohol. Like the two glycols, it is a sweet, syrupy liquid. Glycerol is a product of the hydrolysis of fats and oils.
What is propanediol used for?
Propanediol is a preservative in cosmetics and pharmaceutical products such as conditioner, lotion, shampoo, sunscreen, makeup, hair spray, and other products. It absorbs water, which is why the chemical, food, and pharmaceutical industries use it as an antifreeze when leakage might lead to contact with food.
Is propanediol a glycerin?
The glycerine is more viscous, pinker, and has a more robust scent of strawberry while the propanediol is quite runny, a titch duller in color and smells ‘more candy-like’. Adding (the exact same) botanical powder made quite a visible difference.
