Ditto what the good Gent and Shari and everyone above has said.
Besides the huge learning curve with lye-based soaps, another thing to consider is the time it takes to cure the soap and to watch for any anomalies that might pop up in the following weeks and months after making it, since there are certain potential problems that can occur in lye-based soaps that usually don't show their ugly heads until a few weeks or months have gone by. It would be more than a pity to have sold someone a soap that came down with DOS shortly after they bought it, so giving yourself a good year to observe how your formula behaves over time and under certain conditions, and tweaking out all the bugs, etc... is truly essential.
Re: the term 'natural': I agree 100% with the good Gent and Shari. It's such an overused, overblown term that it has become practically meaningless. I completely avoid using it myself, and I'm very skeptical of products that do use it, especially handmade lye-based soap, because I know that the lye used to make it isn't 'natural', not to mention that many of the oils/fats we use in our soap formulas have been chemically extracted. In the US, the term 'natural' is not regulated (as far as I know), so it pretty much a free-for-all situation where it comes down to how one defines 'natural', as is evident to me every time I walk into my grocery store (
everybody's using it!).
In regards to labeling correctly, (at least in the US), it is against the law to sell any products with any kind of healing claims printed on the labels or in your advertising. I know that many people still do so anyway, but they are breaking the law and can get into some serious trouble. If you do make healing claims, your product in effect comes under the regulation of the FDA and will be considered as being a drug by them which will need to go through the same vigorous testing as drugs, and will have to be approved by them before you can sell it.
