🟢Citric acid information:
When citric acid and sodium hydroxide lye (NaOH) are combined, sodium citrate is created. Sodium citrate works as a chelator in soap.
A chelator traps metal ions such as calcium and magnesium that can be found in tap water.
These metal contaminants can cause rancidity and soap scum in handmade soap.
A chelator binds to these metals so that they can’t bind to the soap molecules. This way the soap won’t react with them and the soap's lather improves + shelf life increases.
Citric acid does not lower the pH of soap. Instead it consumes some of the lye and increases the superfat. Add 6 g extra lye for every 10 g of citric acid added to a soap recipe if you want to keep the superfat % at the same level.
How much citric acid should be added to soap?
Usage rate in bar soap is 1-2% of the oil weight.
How to use citric acid
Add citric acid to the distilled water and dissolve completely before adding the lye, or make a separate solution of citric acid and distilled water and add to the oils.
