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 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 ...
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.
The four components of a SOAP note are Subjective, Objective, Assessment, and Plan. [1] [2] [8] The length and focus of each component of a SOAP note vary depending on the specialty; for instance, a surgical SOAP note is likely to be much briefer than a medical SOAP note, and will focus on issues that relate to post-surgical status.
Soft soap may refer to: Soap that is liquid or easily soluble, usually made by saponification with potassium instead of the more typical sodium hydroxide Softsoap , trade name of a liquid soap product
Perhaps the oldest commercially practiced example of ester hydrolysis is saponification (formation of soap). It is the hydrolysis of a triglyceride (fat) with an aqueous base such as sodium hydroxide (NaOH). During the process, glycerol is formed, and the fatty acids react with the base, converting them to salts. These salts are called soaps ...
Lithium soap is a soap consisting of a lithium salt of a fatty acid. [ 1 ] [ 2 ] Sodium-based and potassium-based soaps are used as cleaning agents in domestic and industrial applications, whereas lithium soaps are used as components of lithium grease (white lithium).
Shaving soap (sometimes called a shaving puck) is a hard soap that is used to produce lather with a shaving brush. The lather it produces is used to coat the face during shaving , softening the hair in preparation for shaving.
