Whitening Cream Formulation

This formulation for a whitening cream appears to be generally usable and contains several ingredients known for their skin brightening properties.

Please note that the concentration of Azelaic Acid at 0.50% is lower than the typically recommended range (5-10%) for significant whitening or oil control effects. You may consider increasing this percentage if you desire stronger results, keeping in mind the recommended usage rate and potential for skin sensitivity.

Here is a suggested method for making this cream using a hot process:

Method of Making

1. Prepare the Water Phase:

   • Combine Water, Glycerin, GlucoBright, and Vitamin B3 in a heat-resistant container.
   • Heat this phase to approximately 70-75°C, stirring until all ingredients are dissolved. Avoid prolonged heating, especially for GlucoBright and Vitamin B3.

2. Prepare the Oil Phase:

   • In a separate container, combine Isohexadecane, Dimethicone, Cetearyl Alcohol, Glyceryl Stearate SE, and Kojic Acid Dipalmitate.
   • Heat this phase to approximately 70-75°C, stirring until all solid ingredients (Cetearyl Alcohol, Glyceryl Stearate SE, Kojic Acid Dipalmitate) are completely melted and dissolved.

3. Emulsification:

   • Slowly pour the hot Oil Phase into the hot Water Phase while continuously stirring with a mixer or homogenizer.
   • Maintain stirring until the mixture cools down and a stable cream emulsion forms.

4. Cooling Phase:

   • Once the cream has cooled to below 40°C, add Azelaic Acid, Phenoxyethanol SA, and Fragrance.
   • Stir well to ensure even distribution of these ingredients.

5. Final Adjustments:

   • Check the pH of the final cream. The optimal pH range for the ingredients in this formula is generally between 5.0 and 6.0.
   • Adjust the pH if necessary using a suitable pH adjuster (e.g., Citric Acid or Sodium Hydroxide solution, used sparingly).

This method should help you create the whitening cream based on your provided formulation. Always perform a small test batch first.
