  • Cleaner using Castile soap

    Posted by Rimshah on July 18, 2019 at 8:45 am

    There 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?

    RECIPE
    80ml distilled water

    15ml Dr bronner’s Castile soap
    4.5ml coconut oil
    0.5ml lavender essential oil

    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.
