Example of saponification reaction of a triglyceride molecule (left) with potassium hydroxide (KOH) yielding glycerol (purple) and salts of fatty acids ().. Saponification value or saponification number (SV or SN) represents the number of milligrams of potassium hydroxide (KOH) or sodium hydroxide (NaOH) required to saponify one gram of fat under the conditions specified.
The Reichert value is an indicator of how much volatile fatty acid can be extracted from a particular fat or oil through saponification. It is equal to the number of millilitres of 0.1 normal hydroxide solution necessary for the neutralization of the water-soluble volatile fatty acids distilled and filtered from 5 grams of a given saponified fat.
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 ...
Total fatty matter (TFM) is one of the most important characteristics describing the quality of soap and is always specified in commercial transactions. It is defined as the total amount of fatty matter, mostly fatty acids, that can be separated from a sample after splitting with a mineral acid, usually hydrochloric acid.
Ice Mountain is a bottled water brand from BlueTriton Brands, produced and marketed primarily in the Midwest region of the United States, first introduced to the public in 2002. [2] Ice Mountain sources its water from two groundwater wells at Sanctuary Spring in Mecosta County, Michigan , and/or Evart Spring in Evart, Michigan .
(The hydroxide solution used in such a titration is typically made from sodium hydroxide, potassium hydroxide, or barium hydroxide.) [1] It is measure of the steam volatile and water insoluble fatty acids, chiefly caprylic, capric and lauric acids, present in oil and fat. The value is named for the chemist who developed it, Eduard Polenske. [2]
Stanley is a brand of food and beverage containers named after William Stanley Jr. who invented the first all-steel insulated vacuum bottle in 1913. The Stanley brand has since been produced by several companies and is currently owned by Pacific Market International (PMI), a subsidiary of the HAVI Group.
The surfactants of shower gels do not come from saponification, that is by reacting a type of oil or fat with lye. Instead, it uses synthetic detergents for surfactants derived from either plant-based sources or petroleum. This gives the product a lower pH value than soap [3] and might also feel less drying to the skin. [4]
