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 ...
The saponins are a subclass of terpenoids, the largest class of plant extracts. The amphipathic nature of saponins gives them activity as surfactants with potential ability to interact with cell membrane components, such as cholesterol and phospholipids, possibly making saponins useful for development of cosmetics and drugs.

Hydrogenation and saponification of castor oil yields 12-hydroxystearic acid, which is then reacted with lithium hydroxide or lithium carbonate to give high-performance lubricant grease. [ 46 ] Since it has a relatively high dielectric constant (4.7), highly refined and dried castor oil is sometimes used as a dielectric fluid within high ...
A handmade soap bar Two equivalent images of the chemical structure of sodium stearate, a typical ingredient found in bar soaps Emulsifying action of soap on oil. Soap is a salt of a fatty acid (sometimes other carboxylic acids) used for cleaning and lubricating products as well as other applications. [1]
The three-part docuseries, Sin City Gigolos: A Murder in Las Vegas, premiering March 4 on Paramount+, is tasked with "documenting a vicious death while weaving together revealing scenes and ...
Foodborne illness kills hundreds of Americans a year, sickens tens of millions annually, and costs billions in medical care, lost productivity and premature deaths, federal researchers said in a ...
The film is practically a work of amateur videography, a home video waiting to capture memories before they’re made — or a wedding video in which a wedding may or may not occur.
This process, called saponification, breaks down the triglyceride (fat); frees the glycerol within; and, results in a sodium salt, sodium tallowate. It is usually combined with sodium cocoate , the sodium salt of coconut oil .
