  • phenylpropanol EHG, Potassium sorbate & sodium benzoate preservative

    Posted by Dtdang on November 3, 2018 at 1:24 am

    Dear Friends,
    I use ingredients that contain potassium sorbate & sodium benzoate. In my formulation, I use phenylpropanol EHG . Is there any conflict between 3 of them.
    What are the best preservatives? 

    Thank you so much for all your help.

    Have you seen a conflict? Is your preservative system working? What did your tests show?

    @Perry, thanks for feedback question. I saw potassium ascorbate and sodium benzoate as a preserves for ingredients that are from making cosmetic 
    but the emulsion occurred very well. Sodium benzoate looks like will produce the ion, Na+ in water, but it is not. I discovered that after replacing coconut oil with babassu oil. The emulsion seem to be more stable and more tolerance with water phase changing.
    ok
