Chelating agent

[Sunibee]

In liquid soap can I add citric acid as a chelating agent . The recipe says potassium carbonate . Which I don't have .

Potassium carbonate is a thickener. It's not a chelator.

Yes, you can use citrate as a chelator. If you add citric acid to the soap to make citrate, be sure to also add the extra KOH for the citric acid to react with.

Thank you DeeAnna, for clarifying . The lady who taught me mentioned Pot Carbonate as a chelator. . ibam so glad I asked my doubt here ..
1 unit citric acid : 8 of KOH ..I hope I got that right .. For liquid soap can I add a little less koh as I want the superfat % in my soap to increase

 

[DeeAnna]

I advise against more than about 3% superfat in liquid soap. When the superfat goes over 3%, the excess fat usually separates from the diluted soap.

Liquid soap isn't nearly as forgiving as bar (NaOH) soap, so don't "eyeball" amounts. Calculate the numbers so you have the most control over what is in the soap. The more accurate relationship -- 10 g citric acid neutralizes 8.42 g KOH

Thank you very much. Will keep that in mind
