Simple Liquid Soap/Shampoo Formulation for Children

Based on the staff's recommendations, for a simple children's liquid soap or shampoo using Cocamidopropyl Betaine and Lauryl Glucoside:

• The remaining portion of the formula can be primarily water.
• You can add thickeners like salt or SugarThick (PEG-120 Methyl Glucose Dioleate) if you prefer a thicker consistency.
• Glycerin can be added to make the texture smoother.
• For preservation, any preservative from the "Preservative" category sold by the company is suitable and safe for children's products.
• Crucially, remember to adjust the pH of the final product to 5.5 using a mild acid like Lactic Acid or Citric Acid to ensure gentleness for children's skin.
