As with the rebatching method, it can be considered a misnomer to refer to the melt and pour process as soap making. The process has much in ...
Saponification is a process of cleaving esters into carboxylate salts and alcohols by the action of aqueous alkali. Typically aqueous sodium hydroxide solutions are used. [1] [2] It is an important type of alkaline hydrolysis. When the carboxylate is long chain, its salt is called a soap. The saponification of ethyl acetate gives sodium acetate ...

A bar of soap can be used to find a leak in anything from an inflatable pool to a bike tire, to a gas leak. A wet bar of soap will form bubbles when there’s air movement, magically finding the leak.
To this end, hydrolysis is conducted in water at 250 °C. The cleavage of triglycerides with base proceeds more quickly than hydrolysis, the process being saponification. Saponification however produces soap, whereas the desired product of hydrolysis are the fatty acids.
