Solid shower scrubs and powdered goats milk

[lola_lola]

I recently made a solid scrub bar with oatmeal and powdered goats milk.
The rest of my ingredients were something like cocoa butter, shea butter, coconut oil, jojoba oil and f/o.

It held up very nicely in the shower, this bar lasted a lot longer than some of the others I have made...but then I read on soapqueen, someone had asked about adding powdered goats milk to her sugar cube recipe and someone from brambleberry replied that it would go sour.

I didn't notice that it went sour, and would it? If it isn't reconstituted with water?

Well, assuming it gets wet, any ingredient that isn't an oil or butter could theoretically be prone to spoilage. I'm thinking specifically about the oatmeal and the goat milk powder in your formulation. I'd be more concerned about bacterial contamination and/or mold than a sour smell personally.

Wouldn't that be a problem with just a solid sugar scrub?
I plan to use a preservative anyway (as soon as it arrives) but wonder still about the milk

Why not made the solid scrubs just large enough for one or two uses. If including powdered milk, I would also use a preservative.

I saved the last bit of it in my shower (now week 3) and have a piece of the original in my kitchen so I can compare them later.
I have been making my own solid scrubs for years (ever since lush discontinued sjg and I got tired of paying for buffy) but this time I had some goats milk powder I had no use for and thought, well, why not? I had steel cut oats in my freezer and ground them up.
Anyway, I am really excited that I have found this forum, soap queens blog, and all the other things available on the internet!
I know that somehow and somewhere, I will find a scrub so good I'll want to marry it!
