Salt Soap Crumbles
(Portland, OR USA)
I'm working on a sea salt soap and want it to be relatively crumble free.
It's been a challenge, and perhaps it's impossible without reducing the amount of salt to a very small percentage.
I want the exfoliating quality to remain, but would like strait, streamlined, rectangular bars. I've tried 50, 30, 25, 20, and 10 percent salt to oil. Oils at 80% coconut, 20% olive/castor. Any thoughts?Answer:
It is quite hard to cut a salt bar and get nice straight edges.
I suggest using a slab soap mold so that you are only cutting the thin side of the bar. Cut as soon as you can handle the soap. Basically as soon as the soap is solid enough to handle...it will likely still be hot.
Even then you may get crumbling.
You could try one of the slab molds with inserts that divide the soap into bars. I've never splurged on one so am not sure how it would work. I think you would still need to remove the soap as soon as possible.
A salt soap isn't really exfoliating even though the bar feels rough. As soon as you start to use it, the bar smooth's out and starts to feel like a polished stone.
For an exfoliating bar, try ingredients like poppy seeds, cornmeal, coffee grounds, herbs, oatmeal, ground pumice and luffa.
