    Hey!

    Can anyone suggest a good and strong emulsifier which should be salt tolerant.

    I’m using zinc pca, as a salt and having difficulty to stabilize the cream formulation. it’s a product for oily skin moisturizer.

    As is about the answer for any emulsifier question, the ‘165’ type is always hard to beat (Glyceryl stearate and PEG 100 Stearate). Might be something to it being the world’s most widely used emulsifier. 😉 Thicken with some fatty alcohols…gel the water a kiss with a gum, and maybe .25% SSG (anionic aspect) to make sure it is bulletproof. BINGO….you’re done.

    Probably would have been helpful….had you listed your last emulsifier package….and supporting cast member….you know…. fatty alcohols….gums….waxy esters….etc. Hard for us to put a puzzle together in the dark.

    Yeah, agree with Grail. You non-ionic emulsifier.

    I also like Polawax GP200 (Cetearyl Alcohol, PEG-20 Stearate). It tolerates high and low pH. Builds nice viscosity.
