Castile or Bastile.....this is just my 2 cents, but if you live and sell in the US it really doesn't matter as far as the law is concerned, and maybe not even as far as many of one's customers is concerned either, unless they are educated on the subject and know the difference. This is especially true here in the US because we've all grown up with popular mass distributed soaps like Kirk's Castile which has never been 100% OO, or Dr. Bronner's which is also not 100% OO.
Kirk's (which has since been bought out by Proctor & Gamble) was actually slapped with a 'cease & desist' order back in the 1920's over this issue, and in the course of doing an amateur, arm-chair investigation of the matter on the web a few years ago, I found out that in the 1930's the 'cease & desist' order was cancelled and Kirk's was allowed to continue labeling their soap as Castile even though it wasn't 100% OO. Y'all can read about my amateur investigation here along with the FTC government links related to the case:

Anyway, if you live and sell only in the US, it's a personal call since you're not actually breaking any written laws and the government won't come after you. Truly (at least here in the US), the worst you'll probably do by labeling a bastardized Castile as Castile is invoke the ire and disdain of many in the handmade soapmaking community. I'll still accept you though. :wink:
'Bastile', as Carebear pointed out, isn't even a real term in regards to soap anyway. It was made up by a fellow soaper over at the SoapDish forum some years back as a joke to mean 'Bastardized Castile'. We all had a good laugh about it, but the name stuck and now everyone thinks it's a real term when it's not.
I agree with AmyW. I would still consider (in my own book) a soap made with 100% OO and 100% goat milk as a Castile, although you could always call it a Baa-stile to be funny. :wink: But the only people who would probably get the joke would be handmade soapmakers, and of those, only the handmade soapers who understand the 'Bastile' joke to begin with. Customers might look at you with a 'deer caught in the headlights' look.
