Common NameStearic acid
DescriptionStearic acid, also known as stearate or 18:0, belongs to the class of organic compounds known as long-chain fatty acids. These are fatty acids with an aliphatic tail that contains between 13 and 21 carbon atoms. Stearic acid is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. Stearic acid is a potentially toxic compound.
