After a lengthy discussion that happened in this post, I wrote to Kevin Dunn of Scientific Soapmaking to ask him a question, and he responded!
Kevin Dunn has put forth this challenge. (To learn more, click here!) "In the Sep/Oct 2014 issue of the Saponifier.com, I discussed the prospect of lowering the pH of liquid soap to pH 7. I remain skeptical that such a thing can be done, but claims to the contrary persist. So I am issuing a friendly challenge to the handcrafted soap community. Send me an 8 oz bottle of your pH 7 liquid soap."
He goes on to specify what the soap must consist of and the awesome way he will be testing the results. If you have brought your soap down to pH 7 AND your soap doesn't contain anything other than water, soap, glycerin, any combination of fatty acids, and citric acid or vinegar, you can send your results to him. I'm dying to see what happens!
