Common Name: Sugar
Major Properties: Sugar in soaps can help to soften the skin, and, helps to promote better and bigger bubbles.
Seriously important info: too much of a good thing can cause problems! You soap can scorch from too much sugar as it cures. Then your soap gets a funny scent, turns funny colours and can cause your colourants to morph. Or cause a soap volcano! I’m serious. It is a thing. Google it.
Why I picked it: Seriously? I love my bubbles. If I could I would add it in huge amounts to see if I could get bigger bubbles!!!!!
Other uses: body scrubs, lip scrubs,
Substitutions: depending on the formula, a straight swap for salt could work.
