Sea Salt Spray
Hello everyone -
I was looking to make a simple Sea salt spray and had some questions i hope the more experienced community can help with!
Understand sea salt spray usually consists of water+epsom salt+carrier oils+essential oils.
But i am seeing ingredient lists of products in the market consisting of preservatives and emulsifiers like polysorbate 20 and PEG40 hydrogenated castor oil.
1) Are they adding the emulsifiers so that upon application, the user would not have to shake the bottle?
2) given the 4 ingredient mixture above, would a preservative even be necessary? if so, why? wouldnt the salt change the PH level enough so that the solution doesnt require a preservative?
Thanks so much in advance all!
