I'm trying to formulate handwash:
5.5% sodium coco-sulfate
1% Coco-glucoside and glyceryl oleate
1% Xanthan gum
0.5% Sodium Benzoate and
1% Citric acid (50% solution)
It looks fine after a few days.( pH is 5.00) But the problem is that, after a few weeks the solutions has become cloudy and there are lot of white pieces in it - like some salt has appeared all of a sudden. Are some ingredients incompatible? Does anyone have a clue?
