What can I use instead of sodium hydroxide in soap making?
You can also use potassium hydroxide. These will produce a softer soap, and in the case of KOH, liquid soap. Those are pretty much your only practical choices. Alkaline earth hydroxides, like Ca(OH)₂, will form insoluble soaps that you are probably familiar with as soap scum resulting from hard water.
What can I use instead of NaOH?
magnesium hydroxide
In summary, magnesium hydroxide is a safe alternative alkali to use as a replacement for sodium hydroxide and is readily available as both a powder and as 63\% solids slurry.
Why is NaOH used in saponification?
Soap is a mixture of sodium salts of various naturally occurring fatty acids. Soap is produced by a saponification or basic hydrolysis reaction of a fat or oil. Currently, sodium carbonate or sodium hydroxide is used to neutralize the fatty acid and convert it to the salt.
Does sodium hydroxide occur naturally?
Sodium hydroxide is also known as lye or soda , or caustic soda. At room temperature, sodium hydroxide is a white crystalline odorless solid that absorbs moisture from the air. It is a synthetically manufactured substance.
How do you make quality liquid soap?
Process
- Add caustic soda solution into the texapon and stir till the whole salt is fully dissolved.
- Add the sulphonic acid little at a time till all is added to it.
- Continually add water to it and stir until the mixture turns whitish.
- Add the dissolved STPP and keep stirring.
- Add the dissolved SLS to the content and stir.
What is saponification oil?
Saponification is a process that involves the conversion of fat, oil, or lipid, into soap and alcohol by the action of aqueous alkali (e.g. NaOH). Soaps are salts of fatty acids, which in turn are carboxylic acids with long carbon chains.
Does soap have sodium hydroxide?
Sodium hydroxide, also called caustic soda or lye, is a traditional ingredient for soap-making.
Why is it important to remove the excess NaOH from the soap after it is made?
Alkalinity (basicity). A soap that contains free alkali (excess NaOH) can damage your skin.
What happens to glycerol in saponification?
Saponification can be defined as a “hydration reaction where free hydroxide breaks the ester bonds between the fatty acids and glycerol of a triglyceride, resulting in free fatty acids and glycerol,” which are each soluble in aqueous solutions.
Where is NaOH found naturally?
Sodium hydroxide is derived from salt water (brine). It is most commonly manufactured by the electrolysis of brine, a salt (NaCl) solution.
