  Your product should be OK for application to skin @Maya, especially with allantoin in it, although it looks under-preserved. Phenoxyethanol alone won’t suffice especially with aloe vera involved (surely you are not relying on “pomegranate extract” for this function, right?) and Polysorbate 20 doesn’t help that case either. Which alkali did you use to neutralize the carbomer with? I don’t see one here.

  @chemicalmatt Can i add Dmdm or sodium benzoate with phenoxyethanol?, And for carbomer maybe i can add NaOH? or better i use xanthan gum?
   I don’t have much knowledge in chemistry, I made this serum just for my own use, thanks for helping me.  sorry if my english is messy.
