I found a m&P recipe for a salt bar on a different forum. I made 2 test batches with 2 different salts. 1st batch. I used:
1/2 pound soap (i used clear you can use white)
1 pound of salt (I used table salt)
1/2 pound of foaming bath butter (melted not whipped)
1 TBSP Shea Butter ( I used grape seed oil it's the only one i had)
add E.O or F.O
I cooled down the mixture before I added the salt. ( dipped my finger in it to see if it was warm to the touch.
This batch set up very very quick, spoon into mold.
2nd batch:
Changed the salt to dead sea salt
was easier to mix, put into silicone log mold, put it into the fridge to help cool down for about 10-15 mins. took it out of my silicone mold and cut the bars while it was still warm.
they looked good last night.have not tried them yet, but excited to do so.
hope this helps.
