Adding guar gum to cold process shampoo?
Hello. i am planning to add 1% guar gum ( hydroxypropyltrimonium chloride) into my cold process shampoo formulation. I need to know the best method to hydrAte/dissolve it perfectly to avoid separation. I am planning to mix it with some distilled water and stir it continuously for 15-20 mins. Then add it to the water phase with rest of ingrediants kept at room temperature. I have water soluble panthenol and hydrolyzed proteins in my water phase too. Do I need to heat the phase to dissolve guar gum or not???
