gelatin method

" you add salt because it helps the soap set up and harden. Always dissolve gelatin in boiling water and make sure all the clumps are gone and don't add food coloring, it'll stain your skin. Soap companies make special pigments that are skin safe and won't stain you or your tubs\showers"

Agar would dissolve too fast -

have to use glycerin - makes it elastic

glycol makes it more durable

carrageenan makes it elastic and durable - needs boiling otherwise it will remain mushy

Best recipe:

50% glycerin
41% water
5% sodium coco sulphate
2% carrageenan
0.5% colorant
1% fragrance
0.5% preservative
