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 12% 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.
