  • Epsom Salt in a Stick

    I want to make a pain stick that has epsom salt in it.  How can I dissolve the salt so that it is not grainy in the stick?  I will use polowax as an emulsifier but can someone guide me in how to do this properly?  I tried dissolving it first in P.G. but it didn’t work.

    Epsom salts are insoluble in oils and waxes. You won’t be able to do it.

    Only possible way would be to dissolve the epsom salts into water first - and then emulsify into the waxes. But you are looking at around 20-25% epsom salts in the water phase.

    Thank you so much for your response.  I actually ended up making a very hard balm and set it into a deodorant tube, yes, using emulsifier and it worked out great.  A little dry, but I can make some adjustments next time. Thanks again for responding.  I really appreciate it.
