Thank you for your information. Yes, I chose these surfactants because they are gentle. I used equal amounts disodium cocoyl glutamate and sodium glutamate for the pH balance and added xanthan gum for viscosity. Now, I need to enhance the cleaning power, so I want to add coco glucoside. For example, I have 5 milligrams of disodium cocoyl glutamate and 5 milligrams of sodium glutamate. How much coco glucoside do you think is needed for the best cleaning? Thank you for your time.😇
