I am looking for some honest feedback on goats milk soap. I havent seen much mentioned about it on this forum
Like judymoody said, there are many posts about this topic. Here are just a few that I found for starters:

For me personally, goat milk soap is very nice, but I draw the line at making any health claims about it (or any other additive used in soap). The intense chemical reactions that go on during saponification cause me to doubt very much whether any of the 'goodies' or pH sensitive components can survive the process or the high pH environment of soap intact. I know that lots of people make marketing claims about it, but to me they are just that- marketing claims. If you ask me, the one obvious or noticeably measurable thing that goat milk in soap has going for it is the 'feel factor'. It lends a really nice creamy feel to the lather (not to mention nice label appeal, too :wink: ).
As for pH- I agree with judymoody. True soap (the kind that we make with lye) is naturally alkaline. If it wasn't, it would cease to be be soap and would be rendered completely impotent in the cleansing department. Quite literally, it would break down and you would be left with a quivering mass of goo. No matter what anybody says, the addition of goat milk will not make for a pH neutral soap. People who say such things are just trying to sell you something. To avoid the hucksters and myths, it would help tremendously to bone up on the chemistry behind true soap. Not to sound like an advertisement or anything (since I do tend to mention his book quite often), but the best place to start is Dr. Kevin Dunn's book, Scientific Soapmaking.

[I am sure my wife knows but a 7% superfat would be castor oil at 7% Is that correct???
Only if you are using 100% castor oil in your batch. It's a soaping myth (a well entrenched one, but a myth nevertheless) that one can add a specific oil at trace and have it remain intact or unsaponified in the finished soap. Dr. Kevin Dunn was able to put that claim to the test in his lab and then lay it to rest (or bust the myth, so to speak) through his experiments laid out in his book that I mentione above, but the myth still persists in cyberspace and in some soaping books. To do a 7% superfat, all you need to do is what Mellifera mentioned in her post, which is to enter your recipe into an online
lye calculator such as SoapCalc, type 7% in the superfat box and then mix all your oils together up front. Don't add any at trace- it's a waste of time and futile.
