first I dispersed xanthan gum, then I heat it up to dissolve PVA. I try to do a base without xanthan gum (just h2O, pva and alcohol) and put it in oven, it seems stable. However, whenever I did a full formulation with xanthan gum, it separate into two layer, upper layer is non clear layer, and the bottom is clear layer. my xanthan gum is not a clear grade. is there something wrong with my process? I truly hope you can help me on this. Thank you 🙂
