  • Preservative combination recommendation for Face cleanser

    Posted by nshu_14 on February 13, 2025 at 2:34 am

    Hello everyone!

    Can someone please recommend me a combination of preservatives for a face cleanser? I cannot use phenoxyethanol due to its restrictions (based on some certification regulations). Thank you so much in advance.

      I am going to use APGs, glycerine, a thickener and preservative. Do you have any suggestions on additional functional ingredient that I can use? Also the suggestion on preservative system ? Many thanks 🙂

        pH : 5.50-5.60. Would you please share how packaging is an important deciding factor for preservative selection?

          Packaging controls risk of exposure, esp. water (Gram neg) exposure.

            Ok, I understood, thank you. So for now, we haven’t thought of packaging. Would your suggestions on this?

              Pump dispensing product reduces risk - esp. if non-suck back mechanism. Some folks who have critical control of all manufacturing risks use simplified preservative systems looking only to mold contamination risk.

              @PhilGeis ”(looking only to mold contamination risk)” is this only in cleansing products or for emulsions and serums too in a pump package?
