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]
A bar of carbolic soap A puck of shaving soap in a ceramic bowl In chemistry , a soap is a salt of a fatty acid . [ 2 ] Household uses for soaps include washing , bathing , and other types of housekeeping , where soaps act as surfactants , emulsifying oils to enable them to be carried away by water.
A near- emptied dispenser of Reeva liquid soap marketed as "Antibacterial" with the active ingredient chloroxylenol, typically for the use of cleaning dishes and hands in kitchens. Antibacterial soap is a soap which contains chemical ingredients that purportedly assist in killing bacteria. [1]
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 and ethanol: C 2 H 5 O 2 CCH 3 + NaOH → C 2 H 5 OH + NaO 2 CCH 3
Most detergents use a combination of various surfactants to balance their performance. Until the 1950s, soap was the predominant surfactant in laundry detergents. By the end of the 1950s so-called "synthetic detergents" (syndets) like branched alkylbenzene sulfonates had largely replaced soap in developed countries.
A foaming agent is a material such as a surfactant or a blowing agent that facilitates the formation of foam.A surfactant, when present in small amounts, reduces surface tension of a liquid (reduces the work needed to create the foam) or increases its colloidal stability by inhibiting coalescence of bubbles. [1]
However, while dish soap may seem like a quick and easy solution, the chemicals that make it so good at making dishes sparkle, can do more harm than good. There are certain surfaces and materials ...
Bar of carbolic soap, demonstrating the rich red colour that gives the soap its alternative name, red soap. Carbolic soap, sometimes referred to as red soap, is a mildly antiseptic soap containing carbolic acid (phenol) and/or cresylic acid (cresol), both of which are phenols derived from either coal tar or petroleum sources.
