You didn't sound snobbish at all. I apologize if I sounded like I was criticizing you because that wasn't my intention. I thought I was being informative but it came out wrong. I just wanted to explain about titanium dioxide which does sound like something which could be hazardous. I want to state again that I consider it natural but not everyone does. Many people don't consider colorants produced from minerals as a "natural" product and will only use botanicals/herbs.
I actually liked your post because it was very informative. It'll cause me to look into TD and make a more informed decision. I just wanted to clarify why I wrote what I did (i.e. not to be snobbish, just to make sure I'm off chemicals since that's my motivation for soap making). If people are snobby about soap they have mental problems. Just saying.
