Question about solubilizer percentage for bath melts
I was gonna play around with some bath melts just for fun and a lot of the recipes I’ve seen online do not include a solubilizer so my question is do I need a solubilizer for bath melts or is that just a matter of preference? And if I do need it, what percentage would I use or ratio of solubilizer to oils? Also, I don’t have any polysorbate but I do have Olivem 300 as well as Cromollient and is there a better one of the two to use in this type of thing..?
Thanks in advance for your help!!
Oh one more question since it’s on topic, what percentage of a solubilizer is necessary for a cleansing oil?
