Recommended Usage for Whitening Ingredients (for 1000g formula)

Hello! Regarding the ingredients you asked about, these are active ingredients and extracts that help with skin whitening. To make a 1000g formula, you can use these ingredients according to the recommended percentages and amounts below:

  • MSH White™ (Undecylenoyl phenylalanine): Use 0.5-2%, recommended at 2% (20 grams)
  • Phenylethyl Resorcinol (e.q. SymWhite 377): Use 0.1-1.0%, recommended at 0.5% (5 grams)
  • Tranexamic Acid (Trans-White™): Use no more than 3% (30 grams)
  • Licorice Extract (Glabridin 4.5%, Water-Soluble): Use 1-2%, recommended at 2% (20 grams)
  • SclareoWhite™ (Sclareolide, Pure): Use 0.1-0.2%, recommended at 0.2% (2 grams)
  • GlyciWhite™ (Glycinamide HCL): Use 3-10%, recommended at 5% (50 grams)
  • Hexylresorcinol AF (e.q. Hentowhite): Use 1-3%, recommended at 3% (30 grams)

Basic Mixing Method:

These ingredients are active substances that need to be mixed into a product base such as a cream, lotion, serum, or gel. The mixing method depends on the solubility properties of each substance:

  1. Water-Soluble Parts: Tranexamic Acid, Licorice Extract, GlyciWhite™, and Hexylresorcinol AF can be dissolved directly in water. High heat should be avoided (GlyciWhite™ no more than 60°C, Licorice Extract should avoid heat).
  2. Oil/Other Solvent Soluble Parts: MSH White™ dissolves in oil with the help of heat at 80°C. SclareoWhite™ dissolves in oil, glycol, or alcohol. Phenylethyl Resorcinol dissolves in oil, but it is recommended to add it in the final step of a cream/lotion formula, using heat no more than 50°C to help it dissolve.
  3. Mixing: Prepare the product base (e.g., a ready-made cream base or make your own base). Then, gradually add the water-soluble and oil-soluble active ingredients according to the appropriate steps for that base formula. Mix thoroughly until well combined.
  4. pH Adjustment: You should check and adjust the pH of the final formula to be within the suitable range for the active ingredients (e.g., Phenylethyl Resorcinol should have a pH of 4-5).
  5. Other Necessary Ingredients: Don't forget other basic ingredients in the formula, such as a preservative, to prevent mold and bacteria.

Since you are a beginner, it is recommended to start by using a ready-made product base to make mixing easier. You should also study the information about the product base you plan to use.
