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]
Sodium laureth sulfate (SLES), an accepted contraction of sodium lauryl ether sulfate, also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste, etc.) and for industrial uses.
Some soapmakers prefer "melt and pour" because the process is simple and safe, allowing the soapmaker to concentrate more on the aesthetic aspects of soap making. Because it avoids the need to handle lye , a hazardous and very caustic chemical, it is a hobby even children can enjoy under adult supervision.

In this context, soap is used in its formal sense, a metal salt of a fatty acid: in this case stearic acid. It is a white solid that repels water. It is a white solid that repels water. It is insoluble in polar solvents such as alcohol and ether but soluble in aromatic hydrocarbons (e.g., benzene ) and chlorinated hydrocarbons when heated.
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.
Glycerin soap can also be produced without remelting soap through directly cooking raw home-made soap. [3] Modern clear glycerin soaps bases are produced by combining various glycerol and polyols with soap and other surfactants in a manner similar to traditional glycerin soap-making methods. These modern clear soaps have the benefit of being ...
