Cream whipped soap & sugar or salt scrub???

Has anyone tried making a cream whipped soap sugar or salt scrub? I've read these will prevent so much oil in the shower/tub and prevent a greasy feel. Anyone made or used this? I am still trying to come up with something different for a sugar/salt scrub

I haven't tried it but it sounds like a great idea.

What kind of preservative should be used. I found a couple of recipes with soap shreds, salt or sugar and oil. But they don't mention preservative ?? Should one be used?

I make a bubblin sugar scrub with shredded soap and I use Liquid Germal as my preservative.

Thanks Billie
