Okay, after the mechanics' soap I talk about in another thread, I'll be attempting a requested facial soap.
The person who asked me is a young woman who is looking for something for blemish control. She's asked for something with red clay, or maybe Moroccan red clay. (I don't know if there is any appreciable difference.) And I do have the clay in hand. (Well, technically, it's back in my soap room. Hard to type otherwise.

)
Anyway, I was thinking about adding a touch of tea tree oil, maybe just a quarter to half ounce per pound, to kind of amp up the blemish fighting abilities. But that brought up a couple of other questions.
I've used tea tree before, and the stuff smells, well, potent, for lack of a better word. So I was thinking about some kind of masking fragrance, if such a thing is possible. But I'm concerned that a fragrance isn't a good thing in a facial soap.
So, I'm torn between three options:
Is the tea tree and clay a good combo, and if so, any suggestions on a fragrance?
Is the tea tree overkill with the clay, and I should just leave it off, it which case the notion of fragrance becomes a moot point?
Or, shall I go with the tea tree but no fragrance and hope she doesn't throw it at me? (I don't really think she would - her dad owns the garage that works on my car and I don't think he'd be amused if that happened.

)
Also, at what point should I add the clay? To the batter, or can I put it in with the oils before the lye solution?
Also, is goats' milk a good idea for the liquid?
Thanks for any and all suggestions.
