DOS... any tips?

[cascarral]

Hello!

I've been founding DOS in my soaps that aren't that old, around 6 months to a year. My recipe is OO, CO, and cocoa butter with 5% SF.

I've been thinking about using sodium citrate, but first I thought I'd ask if in your experience you think it's worth it or I should look for other ways to reduce rancidity like a dehumidifier.

Also, what's the maximum humidity you'd have in your storage room? Maybe it's been getting too humid and I haven't realized.

A dehumidifier might be fine, but it isn't a surefire solution to minimize the chance of rancidity because there are many triggers for rancidity that have little or nothing to do with humidity.

Adding a chelator and/or an antioxidant to your soap can be extremely effective. If you can only use one, I'd recommend the chelator.

Thank you! I will definitely try it. Sodium Citrate is a chelator, right?

Yes -- see here: Soapy Stuff

You'll also want to check the section about acids immediately above the "chelator" section if you want to make sodium citrate by reacting citric acid and NaOH in your soap making process.
