Dewy Skin Mist Preservative Question
Hey Everyone!
I need to get a preservative for the below formula and was hoping that I could get some advice to what would be appropriate.
The ingredient with asterisks is something that comes with it’s own preservative as you can see from the Gluconolacctone and Sodium Benzoate.
I was told that I would need to use a preservative for any additional water based products.Can someone please school me on what preservative would work?
Thank you so much!!

You’ve got plenty of options, probably best to get a blend to start that offers broad-spectrum coverage (yeast and mold as well as bacteria).
If you can test pH reliably (not pH strips) and keep your product below pH 5.5, then you can use additional sodium benzoate, potassium sorbate. Otherwise stick with something like phenonip or germabenIf you do not add an emulsifier your squalane will sit separate from your water phase.
