Is it safe to use sodium hydroxide in soap?
It’s commonly known as lye, or caustic soda. It’s an extremely caustic and reactive inorganic compound. This leads many to ask, is sodium hydroxide safe to use in soap and cosmetics? The short answer is yes, as sodium hydroxide goes through saponification to make soap.
What sodium is used in making soap?
sodium hydroxide
Soap is formed by mixing fats or oils with strong bases, such as sodium hydroxide. Sodium hydroxide is also called lye. The traditional way to make lye is to leach ashes with water. The ashes contain substantial amounts of sodium hydroxide, which dissolves in the water, forming a solution of sodium hydroxide.
Can we make soap without sodium hydroxide?
The main way that you can make soap without handling lye is by using melt-and-pour soap. It’s already been through saponification (oils reacting with lye) and is safe to use and handle straight out of the package. Clear glycerin soap, creamy goat milk soap, palm-oil free, the list goes on.
Can soap be made without sodium hydroxide?
All REAL soap is made with lye (sodium hydroxide mixed with liquid). Any skin or hair cleansing product made without sodium hydroxide is not soap, it is detergent.
Is lye and sodium hydroxide the same?
Sodium hydroxide (NaOH), also known as caustic soda or lye, is a highly versatile substance used in a variety of manufacturing processes. Sodium hydroxide is a co-product of chlorine production.
What is the difference between lye and sodium hydroxide?
Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. Its common name derives from its chemical identity as a sodium hydrate and because it is caustic or corrosive. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.
What is lye used for in soap?
Sodium hydroxide (also called caustic soda or lye) is commonly used to create solid bars of soap, while potassium hydroxide is used to make liquid soap. Once that reaction is complete, you no longer have fat or lye—you have created soap. Even most store-bought soaps are made with lye.
Why sodium hydroxide is used in soap?
Sodium hydroxide is a reagent, or a substance used in a chemical reaction to produce other substances. Caustic soda causes saponification and is an essential ingredient in soap-making. This solution, when mixed with oils or fats, will lead to the chemical reaction called saponification.
Is sodium hydroxide safe for skin?
Safety Information Due to its strong corrosive qualities, exposure to sodium hydroxide in its solid or solution form can cause skin and eye irritation, according to the U.S. Centers for Disease Control and Prevention Agency for Toxic Substances and Disease Registry.
