the process used to make soap; the reaction of an ester with a strong base to form a soap and glycerol; it invlolves the hydrolysis of fats or oils by an aqueous solution of the strong base.
saponification is the reaction of a fat or oil with a strong alkali to form glycerol and soap. The theoretical amount of alkali required to saponify all the oil is given by the saponification value. And is defined as the number of milligrams of potassium hydroxide required to saponify one gram of oil or fat.
Saponification refers to alkali attack on the binder a paint and usually takes the form of blisters on the paint film. Blisters form in poor adhesion areas of the film. Very often a yellow oil-like substance is exuded from these blisters.
Chemical reaction in which an ester is hydrolyzed by a base. In the case of fats, the ester is broken down into glycerol and fatty acid salts; the latter are soaps.
The chemical reaction between a fatty acid and an alkaline compound creating soap.
The process under moist and alkaline conditions in which a paint binder becomes transparent or discolored.
the chemical process which produces soap. During saponification, a fatty acid (in our case, the oils) and a base (we use sodium hydroxide - commonly known as lye) react with one another and neutralize into a salt (or soap).
saponify; saponified; saponifies. The hydrolysis of esters using hot sodium hydroxide solution to produce the salt of a carboxylic acid. Usually saponification refers to the hydrolysis of esters of fatty acids to manufacture soaps.
chemical hydrolysis of glycerides by the action of heat and sodium hydroxide
a chemical reaction in which an ester is heated with an alkali (especially the alkaline hydrolysis of a fat or oil to make soap)
The reaction of an ester with a metallic base and water. The making of soap. This happens sometimes when you use too much lye in a biodiesel reaction... No worries - you can re-react the resulting top layer of unreacted liquid, and if you wish you can turn the semi-solid bottom layer into soap by adding more lye (make sure you know how much to add...).
The alkaline hydrolysis of fats and oils where ester linkages of triglycerides are cleaved by hydroxide ions, yielding glycerine and soap.
The process or reaction of combining a base (fat) with an alkali (sodium hydroxide) to produce a salt (soap) and a free alcohol (glycerin).
The centuries-old process of producing simple soaps. It involves the boiling and mixing of acidic natural oils (from animals or plants) and alkaline substances (sodium hydroxide from wood ashes) thereby, producing a "true soap." Saponification also describes the cleaning process as done by alkaline compounds in detergents. In this case, alkalis mix with oily soils and water forming a type of "salt" that is rinsed away.
the process of converting fats into soaps and glycerol by heating with alkalis.
A hydrolysis reaction carried out in an alkaline solution. The preparation of soaps from fats.
The breaking down of oils into very fine droplets called colloids; to hydrolyze a fat with alkali to form a soap and glycerol.
A chemical decomposition of a paint's binder by alkali and moisture from a substrate (e.g., new concrete or fresh plaster). Saponified paint may deteriorate, lose its adhesion, and become discoloured.
A hydrolysis of an ester carried out in the presence of alkali. (Saponification of natural fats and oils yields soaps and glycerol.)
The chemical reaction that takes place when fats/oils are combined with lye, resulting in five parts soap and one part glycerin.
a complex chemical reaction; fatty acid reacts to a base to make soap and glycerin
The process of converting a fat into soap by treating it with an alkali. Also the process used by some to remove grease and oil.
The alkaline hydrolysis of fats whereby a soap is formed; typical reaction between alkyds and galvanized metals resulting in peeling.
Chemical process that occurs when oils/fats are combined with lye.
Hydrolysis of esters in the presence of strong soluable bases.
Breakdown of a paint film resulting from the action of alkali on the binder medium in paint.
The reaction between a caustic alkali (lye) and the fatty acids in a vegetable oil or animal fat which results in soap. (see How Is Soap Made? and The Chemistry of Soap)
The reaction of an ester with a metallic base and water, i.e. the making of soap.
The chemical reaction between a fat or oil and an alkaline compound creating glycerol and soap.
The process in which a paint binder, under moist and alkaline conditions, becomes transparent or discoloured.
the hydrolysis of a fat by alkali with the formation of a soap and glycerol.
A form of hydrolysis where an alkali is added to an oil to change it into a solid (soap). Alkali (powder, likely potassium hydroxide or sodium hydroxide) is added to water and the oil, and the reaction creates soap and glycerin, while leaving the water. A variety of suitable oils exist - coconut, olive, safflower, etc., many of them can be found on the carrier oils details page.

Saponification is the reaction of a fat or oil with a strong alkali to form glycerol and soap. The theoretical amount of an alkali required is given by the Saponification Value of the oil or fat. This is defined as the number of milligrams of potassium hydroxide required to saponify one gram of oil or fat. From the Saponification Value may be calculated the Saponification Equivalent which is the number of grams of an oil or fat saponified by one gram equivalent of potassium hydroxide.
Saponification is the hydrolysis of an ester under basic conditions to form an alcohol and the salt of a carboxylic acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap. Saponifiable substances are those that can be converted into soap.
