what is called saponification?

Answer 1

"Saponification is the hydrolysis of an ester under basic conditions to form an alcohol and the salt of the acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap."


so in other words..soap is saponification

Answer 2

Saponification is the hydrolysis of an ester under basic conditions to form an alcohol and the salt of the acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap.

Lye is a form of sodium hydroxide (NaOH) which is a caustic base. If NaOH is used a hard soap is formed, whereas a soft soap is formed when potassium hydroxide (KOH) is used.

Vegetable oils and animal fats are fatty esters in the form of triglycerides. The alkali breaks the ester bond and releases the fatty acid and glycerol.

The soap is salted out by precipitating it with saturated sodium chloride.

Saponification in corpses:
Saponification can also refer to the conversion of fat and other soft tissue in a corpse into adipocere. This process is more common where the amount of fatty tissue is high, the agents of decomposition absent or only minutely present, and the burial ground is particularly alkali.

Saponification in fire extinguishers:
Fires involving cooking fats and oils should be extinguished with a Wet Chemical Extinguisher. Extinguishers of this type are designed to extinguish cooking fats and oils through saponification. The extinguishing agent rapidly converts the burning substance to a non-combustible soap. This process also has a cooling effect, and suppresses the flames with steam.

Answer 3

Saponification is a term used to define the reaction of a metallic alkaline or a base with a fat or oil to form soap.

Answer 4

The term saponification is the name given to the chemical reaction that occurs when a vegetable oil or animal fat is mixed with a strong alkali. The products of the reaction are two: soap and glycerin. Water is also present, but it does not enter into the chemical reaction. The water is only a vehicle for the alkali, which is otherwise a dry powder.
The name saponification literally means "soap making". The root word, "sapo", is Latin for soap. The Italian word for soap is sapone. Soap making as an art has its origins in ancient Babylon around 2500 - 2800 BC.

The oils used in modern handmade soap are carefully chosen by the soap maker for the character they impart to the final soap. Coconut oil creates lots of glycerin, makes big bubbly lather, and is very stable. Olive oil has natural antioxidants and its soap makes a creamier lather. Tallow, or rendered beef fat, makes a white, stately bar that is firm and creates abundant lather. Many other oils can be used, each one for a specific reason. Your soap maker will be glad to tell you which oils are used to make her or his soap.

The alkali used in modern soap is either potassium hydroxide, which is used to make soft soap or liquid soap because of its greater solubility, or sodium hydroxide, which is used to make bar soap. The common term for the alkali became simply "lye", which curiously is not short for alkali, but originated in the Anglo-Saxon language.

Soap made in cottages and on farms in earlier American times became known as "lye soap". That term is now pejorative and derogatory and denotes a harsh soap that would irritate your skin. The old soap got a bad name because it had an excessive amount of caustic. Weighing and measuring techniques were crude, and knowledge of soap chemistry was elementary or non-existent.

The true fact is that modern handcrafted soap, though necessarily made with lye to get true soap, has no lye in the final product. It has all been reacted with the oils to form soap and glycerin.
