I bought “Scientific Soap Making” out of an abiding respect for Science, and figured it would make a good research and reference tool, answering why things went south, with a scientific explanation of what was happening. I was wrong. It is more of a science course in soap making, and goes off the deep end right at the start. The other book I bought before that would have required hundreds of dollars worth of oils, colorants, essential and fragrance oils just to sample a few of its recipes. So... While I’ve been turning to the Internet and Soap Forum, I’d really like a good reference book that is based on fact more than opinion or consensus, without making me have to invest in a lot of equipment to be the scientist I’m not. Anybody have any recommendations?
