Hello, I make a body wash that has 1% Poly-7 and uses xanthan gum as the thickener.  The surfactants are Decyl Glucoside, Cocoa Betain and Capryly Glucoside. The wash lathers well and feels great, which I am sure is due to the Poly-7. My issue is the wash sepearates after a few days and has to be shaken to reincorporoate. I have since removed the xanthan gum and thicken with Crothix.  But sometimes a lot is needed depending on the fragrance used. My question is do the xanthan gum clear or soft perform differently than store brought xanthan gum with Poly-7? If not, any suggestions on what gum/thickener (other than Crothix) to use to get the thickness while keeping Poly-7 in the formula? Or is there a good sub for Poly-7 that plays well with xanthan gum? Sorry for all the questions.
