Liquid Body Wash Formulation: Mixing Procedure and Oil Solubility

Based on the liquid soap formulation you provided, here are the mixing instructions:

1. Combine the water-soluble ingredients: Water (72.5%), Glycerin (10%), Hydro Protein (2.5%), Aloe Vera Extract (1%), and Cucumber Extract (3%). Mix well until everything is dissolved and uniform.
2. Add the surfactants: Add Lauryl Glucoside (5%) and Coco Wash (PEG-7 Glyceryl Cocoate) (4%) to the water phase. Stir gently to avoid creating too much foam, mixing until the solution is homogeneous.
3. Incorporate the oils: Lavender Oil (1%) and Orange Oil (1%) are oil-soluble and will not dissolve directly in water. To incorporate them into your liquid soap, you need a solubilizer.
   • Method 1 (Using existing ingredients - may result in cloudiness): In a separate small container, mix the Lavender Oil and Orange Oil together. Then, add a small amount of Coco Wash (or Lauryl Glucoside) from your formulation to the oils (e.g., use a portion of the 4% Coco Wash). Mix the oil/surfactant blend thoroughly until the oils are dispersed. Slowly add this blend to the main batch while stirring gently.
   • Method 2 (Recommended for clarity/stability): Use a dedicated solubilizer (like Polysorbate 20 or PEG-40 Hydrogenated Castor Oil - not listed in your formula, but commonly used). Mix the Lavender Oil and Orange Oil with the recommended amount of the solubilizer in a separate container until clear. Then, slowly add this mixture to the main batch while stirring.
4. Adjust pH: Check the pH of the mixture. Dissolve Citric Acid (amount needed to adjust pH) in a small amount of water. Add this solution dropwise to the soap mixture, stirring well after each addition, until the desired pH is reached (typically between 5.5 and 6.5 for body wash).
5. Add Preservative (Recommended): If your ingredients do not already contain a preservative, it is highly recommended to add one at the appropriate usage rate to prevent microbial growth.

Mix thoroughly after each addition.
