SUSAN'S ATTEMPT #4 and final recipe
40% berry sugar (finer grain than white sugar)30% baking soda (Arm & Hammer brand)
18% coconut oil
2% cream of tartar
2% fragrance oil - Hello Sweet Thang!
I switched the mango and shea butter for coconut oil. I don't think it's more or less moisturizing than the other version, although it is whiter and would be cheaper to make if one were to market this. Do not use a fragrance oil with vanilla in it - it will discolour very quickly, even overnight.
I think it's a nice bar, very easy to make, would be very easy to mold and make look very pretty (see Petra's pictures below) but I would still like a titch more oils for post-shower moisturization. I'm going to play with this to include some conditioning agents and emulsifiers - I couldn't do that as we wanted to stay with the original ingredients - and see how I like it!
32.0% baking soda
11% cream of tartar
10% virgin coconut oil
1% shea butter
I remember trying the VCO at 10% and shea at 2% and found that I was getting a "greasy smear" which I attributed to the shea. I left the VCO the same and reduced the shea to 1% and voula! perfect! I also reduced the SLSa a bit I don't remember if it was down to 8% or 10%.
I have decided to offer this strictly "unscented". The natural scent of the coconut is too nice to cover up. I am calling them coconut sugar scrubs and molding them in a heart mold (I think it is an IKEA mold as well). Not sure if this factors into the final product, but one thing I have been doing is unmolding and "drying" them on a terry towel (although I am adding no moisture). It seems more forgiving when I put it out of the mold and seems to suspend the scrub above the surface a bit. My plan is to put "naked" scrubs in a jar and also sell individual scrubs wrapped in a silver foil wrapper and put in an apothecary jar.
(Petra's version is much prettier than mine!)
So what did Petra and I learn on this adventure? I think it's interesting that without even discussing batch #1, we moved closer to using the same ingredients in almost the same amounts, but we still have some differences. We both have surfactants acting more as emulsifiers than as foamers. And we both want lots of moisturizing power from the oils! Petra's is only slightly less scrubby than mine - 70% exfoliants in Swift's vs. 68% in Petra's - and mine is a little more oily. I think Petra's is more likely closer to the product from Lush!
