    A soap substitute is a natural or synthetic cleaning product used in place of soap or other detergents, typically to reduce environmental impact or health harms or provide other benefits. Traditionally, soap has been made from animal or plant derived fats and has been used by humans for cleaning purposes for several thousand years. [ 1 ]

  3. Saponification - Wikipedia

    en.wikipedia.org/wiki/Saponification

    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

  4. Lye - Wikipedia

    en.wikipedia.org/wiki/Lye

    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 ...

  5. Saponification value - Wikipedia

    en.wikipedia.org/wiki/Saponification_value

    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 ...

    Soap or detergent; Sodium carbonate (washing soda) Sodium bicarbonate (baking soda) Sodium hydroxide (lye) Sodium hypochlorite (liquid bleach) Sodium perborate; Sodium percarbonate; Tetrachloroethylene (dry cleaning) Trisodium phosphate; Water, the most common cleaning agent, which is a very powerful polar solvent; Xylene (can damage plastics)

  7. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Other common uses of sodium hydroxide include: for making soaps and detergents. Sodium hydroxide is used for hard bar soap, while potassium hydroxide is used for liquid soaps. [31] [32] Sodium hydroxide is used more often than potassium hydroxide because it is cheaper and a smaller quantity is needed.
