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 higher the saponification value, the lower the fatty acids average length, the lighter the mean molecular weight of triglycerides and vice versa. Practically, fats or oils with high saponification value (such as coconut and palm oil) are more suitable for soap making.
Ester hydrolysis is an organic reaction which hydrolyzes an ester to a carboxylic acid or carboxylate, and an alcohol. It can be performed with acid as catalyst, or with base as reagent. It can be performed with acid as catalyst, or with base as reagent.
Pears soap was made using a process entirely different from other soaps. A mixture of tallow and other fats was saponified by an alkali.This is currently caustic soda (sodium hydroxide) since the ingredients list shows sodium salts of fatty acids, but a chemist reports that in the 1960s, caustic potash (potassium hydroxide) was used.
The principal historical use of these plants was boiling down to make soap. Saponaria officinalis is most suited for this procedure, but other related species also work. The greatest concentration of saponin occurs during flowering, with the most saponin found in the woody stems and roots, but the leaves also contain some.
Glycerin soap is made by melting and continuously heating soap that has been partially dissolved in a high-percentage alcohol solution until the mixture reaches a clear, jelly-like consistency. [3] The alcohol is added to a slow cooked hot-processed soap and then simmered with a sugar solution until the soap is clear or translucent, and then ...
The "cilantro soap gene" is a genetic factor that makes cilantro taste and smell like soap. A study from 23andMe reveals the OR6A2 gene as a possible cause for some people's distinct cilantro ...
The meltable base is usually naturally rich in glycerine, a by-product of saponification that has humectant and emollient properties, whereas commercial soap bars have often had this component removed. 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 ...
