What is required to keep soap kosher and halal? I know that it can't be pork for halal, but does it need the fat need to be procured from a halal butcher? does the lye need any special treatment? Is it even relevant to a non-food item?
What about kosher? I believe dairy and meat can't mix (is that correct? thats what I"ve been reading) but I'm not sure if it applies to soap.
What details do I need to know to keep soap all inclusive? (I've already figured vegetarian, ovo-lacto vegetarian and vegan).
Searches i've done...the web generally, ask-an-imam (no response as of yet), wiki, and the halal knowledge center.
Sorry if this is offensive - I"m trying not to be and making sure not to offend by getting it wrong!
