  combining preservatives

  Posted by Quinn13 on October 18, 2024 at 3:19 am

  Hi, looking for some advice on combining preservatives…

  I have some hydrosols and aloe vera juice that already contain sodium benzoate and potassium sorbate (@1%). I want to eventually use these ingredients in various products, including a face scrub formula that requires a ph of 6.2-6.7, but I want to use more effective/ph appropriate preservatives.

  The face scrub formula suggested the use of either:

  phenoxyethanol/ethelhexylglycerin;

  naticide, or;

  preservative eco/geogard ect.

  Could I combine one of these with the SB PS? If so, should the usage level be modified?

  There’s probably no simple answer, but if anyone has any advice/suggestions, that would be much appreciated!
