Lye is another name for the chemical Sodium Hydroxide (formula: NaOH).
Sodium hydroxide is a caustic alkali. It is very harmful because it reacts with fats to make soap. If you get some on your hands, for example, it makes you hands feel soapy because it is actually turning the fat from your skin into soap.
It also reacts with many other substances such as metal, paint, cloth and plastic. Great care must be taken in its use because of this reactivity. It is often used as a strong method of cleaning, for example unblocking drains or polishing metals.
Lye is made from the reaction of soda (Sodium Carbonate) and lime (Calcium Hydroxide). It is also produced by the electrolysis of an aqueous solution of Sodium Chloride (table salt).
The major use of sodium hydroxide today is in the production of soap. Soap is made by taking fat, which is made up of three long chain fatty acids joined by an ester bond to glycerol. Sodium hydroxide breaks the ester bond to form glycerol and the fatty acids which are used as soap because of their long hydrophobic tails and charged, hydrophilic heads.
