How Much Sodium Lactate Should I use in M&P Soap?

[xoticsoaps]

I've just discovered the uses for sodium lactate in beauty products. It adds hardness and works as a humectant, among other things. So, if I were to use it, how much should I add per 1lb of base?

I tried looking online, but it seems this may not be all that common with m&p soap. I suppose some tinkering may be in order if I decided to use it.:think:

it does adds hardness, but to cp/hp soaps i believe, and not mp.

Hmm... I may have to experiment with this, then.

the thing is, mp soap already contains glycerin, which is a humectant. as far as the hardness thingy, most mp soap is already quite hard, i dunno why you want to make it harder?

If I added certain ingredients that made the soap softer than I wanted once it comes out of the mold, then I thought that maybe I could use the sodium lactate as a fix and save the soap.
