Hi everyone,
Before I ask my question, I just wanted to say how much I enjoy reading this forum and I love that everyone is here to help each other. Thanks to those of you who have answered my previous questions. YOU ALL ROCK!
So here's my question. I've been reading about using polysorbate in bath bombs and I'm interested in picking some up to see how it helps out. According to most of the information I've read, it's supposed to help extend the fizzing (though how it does that, I'm unclear. Anyone have an explanation?)
What I really want to know though is which one I should use--the 20 or the 80? I notice that some websites (like Bramble Berry) only carry the 80. Others only carry the 20, and still others carry both. It sounds as though the 80 prolongs the fizzing better, but when I look on the ingredient list of people who sell their bath bombs, I'm seeing polysorbate 20 pretty exclusively, which makes me wonder. So which makes the better bath bomb? The 20 or the 80?
For my purposes, I'm primarily interested in producing a more powerful fizz/extending the duration of the fizz. I haven't really had problems with color rings around the tub or floating oil.
Any advice on which is the better product? Pros and cons? I also read that the polysorbate helps to make an emulsifying salt/sugar scrub which I'm also interested in trying out, though again I don't know which of the two products would be better.
