Regarding the formula, we will have to wait for the staff to answer. Please allow me to present another simple option that the staff used to recommend for facial cleansing gel. "If it's a general cleansing product, you can use
Sulfate Free Shampoo Base about 15-20% mixed with water if you want it as a lotion. Add a small amount of any oil to
Sulfate Free Shampoo Base and then add to the water."
