    12.0 Eversoft UCS-30S (SinoLion)

    11.2 Pureact Gluco C (Innospec)

    3.0 TegoRemo 95MB (Evonik)

    To 100.0 Water

    1.0 Geogard ECT (Lonza)

    q.s. pH adjuster

    What’s your list of INCI ingredients?

     @Mayday Is it the Eversoft UCS-30S (SinoLion) Disodium Cocoyl Glutamate as its anionic?

    18.7 Miranol Ultra C-32 (Solvay) - sodium cocoamphoacetate

    12.0 Eversoft UCS-30S (SinoLion) -  Disodium Cocoyl Glutamate
    11.2 Pureact Gluco C (Innospec) - coco glucoside
    3.0 TegoRemo 95MB (Evonik) -  Sorbitan Caprylate (and) Glyceryl Oleate
    To 100.0 Water
    1.0 Geogard ECT (Lonza) - Benzyl Alcohol (and) Salicylic Acid (and) Glycerin (and) Sorbic Acid
    q.s. pH adjuster citric acid

    @Hanson25 I don’t know really know anything about surfactant interactions, but the sodium cocoamphoacecate may be it because it’s amphoteric and you say the viscosity is changing with pH.

    Sorbitan Caprylate (and) Glyceryl Oleate increases the viscosity up to some point. After that it will decrease it.

    @Hanson25 it might be the case that when adjusting the pH of your cocoamphoacetate, you’re changing its ionic state, making it interact better with your anionic surfactant, but I’ll need to check its pKa values.
