  • W/O emulsion preservation

    Posted by Cdsgames on April 22, 2025 at 3:50 am

    Hello ,

    I am working with a W/O emulsion at pH7 to 7.1 and trying to determine the best way to preserve it .

    I am using PEA at 0.8 , glycol (propanediol and pentylene glycol at around 2.2% water phase) and Magnolia bark extract in the lipid phase .

    My question is, is w/o considered easier to preserve than o/w ? Any tips on how to improve the preservation at 7 to 7.1pH ? (I cannot use Glyceryl caprilate at 7.1…or can I ? Some companies claim that it works until pH 7.5). I am even thinking to use zinc lactates..

    Thx you for your time.
