Cleaner using Castile soap
Posted by Rimshah on July 18, 2019 at 8:45 amThere are a number of recipes on internet using Castile soap to make a hand wash, body wash, floor cleaner, etc.
I am curious to know how do you preserve this hand wash recipe?

You don’t even need to preserve it. It has extremely high pH. Bacteria just die 🙂

Okay, thank you
I have found a few studies claiming that skin balances its pH naturally within 15 to 90 minutes if using rinse-off product, only leave-on product damages the acid mantle. However, I have found more studies regarding increasing the pH even following rinse off products. Do you have any helpful information to share?

What is the final pH? The Castille Soap has a high pH, but at 15% wt/wt of the final product, it would likely be a different final pH.

I didn’t experiment yet but went through various websites and concluded that there would be a very slight difference in pH.

I would test that and prove it empirically. I am somewhat skeptical that a 15% solution would still maintain a pH of the original product.

Perfect. That was really what I was hinting at. These properties can’t be extrapolated by reading a few blogs, but rather with simple experimentation in the lab.
