    I have issue with my body wash and need some suggestions and guidance. 
    After several weeks, my solution separates into two layers. 

    My formula : 
    Water 83%
    Coco-glucoside 50% 6%
    Betaine 30% 10%
    Xanthan gum 0.4%
    DMDM H 0.6%

    Is there anything wrong with the formula ? 
    Or there is a specfic way to mix the ingredients so that it wont separate ? 
    How can I improve it ?
    Thank you.

    @h__w Xanthan gum can be tricky to work with sometimes. Did you add Xanthan gum as the first ingredient directly to the water while vigurously mixing, keeping this mixing for at least 15-20 min? I’d then add the Coco-glucoside, Betaine and DHDH H in that order. Also, what’s your final viscosity?

    ahh,, perhaphs thats the issue, i didnt mix enough and i put the Xanthan gum after all the sufractants,, 

    If I use CMC in replace of Xanthan gum, do I do the same process ? and is it easier to work with ? 

    I didn’t calculate the vicosity yet. Does calculating the viscosity help with the formulation ? and I know we have to be precise with the grams and all the stuff,, but what is the tolerateable margin of error for most products any heads up ? 

    And thank you so much for your suggestion ! @ketchito

    @h__w No worries. The viscosity thing is only in case the viscosity is very high, with the product like a gel, which could influence. But I believe that’s not the case.

    Try to make one sample then mixing the Xanthan gum in a better way, and before the surfactants. This is a common procedure for gums and natural/natural derived polymers in general.

    @h__w If you want to add Xanthan gum after surfactants, you can mix it with equal amount of glycerin, and add.
