    Hi

    Iam making a facial cleanser for dry skin

    The formula

    Decyl glycoside 10%

    Betaine 5%

    Caprylic triglyceride 3% with polysorbate 3%

    Ceramide 0.5%

    Glycerin 5%

    Probylene glycol 5%

    Germall 0.5%

    EDTA 0.5%

    Hyaluronic acid 0.2%

    The problem is that hyaluronic acid keeps separating from the formula.. i tried high sheer mixer to blend it in but it didn’t work

    Any suggestions

      Adding glycerin to polyquatrinum 10 with water until dissolved

      Then adding decyl glycoside with betaine and adding lactic acid to adjust ph

      Then ceramide and germall, EDTA

      Then caprylic with polysorbate 20

      Finally hyaluronic acid dissolved in water

        Did you continue stirring while the hyaluronic acid hydrates? Just wondering about that.

    @Rana_91

    What molecular weight HA are you using? This will probably work with a HA < 50 kDa, but not with higher mw HA

    Did you do a knockout test, just to confirm it’s the HA?
