Depending on the nature of the alkali used in their production, soaps have distinct properties. Sodium hydroxide (NaOH) produces "hard" soaps; hard soaps can also be used in water containing Mg, Cl, and Ca salts. [5] By contrast, potassium soaps (derived using KOH) are "soft" soaps. The fatty acid source also affects the soap's melting point.
Sodium hydroxide is a popular strong base used in industry. Sodium hydroxide is used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis. In bulk, it is most often handled as an aqueous solution, [28] since solutions are cheaper and easier to handle.
Both sodium hydroxide and potassium hydroxide are used in making soap. Potassium hydroxide soaps are softer and more easily dissolved in water than sodium hydroxide soaps. Sodium hydroxide and potassium hydroxide are not interchangeable in either the proportions required or the properties produced in making soaps. [citation needed] "Hot process ...
Handmade soap makers who aim for bar soap use sodium hydroxide (NaOH), commonly known as lye, rather than KOH (caustic potash) which produces soft paste, gel or liquid soaps. In order to calculate the lye amount needed to make bar soap, KOH values of SV can be converted to NaOH values by dividing KOH values by the ratio of the molecular weights ...
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]
Its manufacture often differs slightly from normal bath soap in that both potassium hydroxide and sodium hydroxide may be used as saponification agents. Sodium hydroxide creates a harder soap such as is used in pucks, where potassium hydroxide facilitates creation of a softer soap which loads on the brush more easily. [6]

Alkaline stain removers are mostly used in the removal of oil-based stains via the process of saponification. [6] Sodium Hydroxide is also commonly used in drain cleaners. It allows grease and other oils to dissolve into aqueous solutions like water. Other alkalis such as Potassium Hydroxide (much stronger than Sodium Hydroxide) are also used ...
