I just started making soap and was using my candle scents in them,and just wasn't too happy with any of the ones I used, some didn't smell like anything that they were suppose to be, most changed colors terribly, I didn't have much luck at all. Then I started reading the soap suppliers web-sites and most of them test only in cp soap. I have started using OT, and am very happy with their scent,,,,although the shipping is very slow. They don't use UPS or USPS. So, if you can order about two weeks ahead of the time you need your stuff, they are great. I am gonna try some more soap making suppliers, at least with the descriptions they give, you kinda know what to expect, and when you are just starting out, that is important.
