    Hi everyone,

    I’m making a thick cream and I noticed something I’ve never seen before in my emulsions. It starts separating almost and becomes very thick at emulsion temperature (75C). I tried to put on my skin and it hardens as soon as it contacts the skin at this point. As I keep mixing while cooling down, it starts to form the emulsion at around 40C. I checked under the microscope and it looks like a tight emulsion so I’m not sure what is happening. Any thoughts?

    Here’s my oil phase and I’m using Xanthan gum as water thickener at 0.5%:

    Naturemuls (Candelilla/Jojoba/Rice Bran Polyglyceryl-3 Esters, Glyceryl Stearate, Cetearyl Alcohol, Sodium Stearoyl Lactylate) - 7%
    Cetyl Alcohol - 2%
    Hectorite gel soft - 2%
    Squalane - 5%
    Lexfeel n5 - 5%
    Shea Butter - 3%
    Preservative - 1%

    I appreciate the input. Thank you.

    Following…. I have had repeated similar issues with the Montanov series.  End up with something good, but worries me like crazy, when it will not go together, at the combining temp.  My formula is rather different than yours.
