Whitening and Anti-Acne Formulation with Aloe Vera Gel Base

Yes, it is possible to create a whitening and anti-acne formulation using an aloe vera gel base with Stabilized Vitamin C and Azelaic Acid.

You can use an aloe vera gel base such as Aloe Vera Gel (Heavy) or Aloe Vera Gel (Lite).

Adding Azelaic Acid (Liquid Azelaic™) at 10% to a gel base will likely cause the gel to become thinner. To counteract this and maintain a thicker gel consistency, you can add a thickener like Pro Polymer™ (Gel Maker). The staff recommends adding about 1% of Pro Polymer to significantly increase the gel's viscosity before incorporating the Azelaic Acid. If a thinner gel texture is acceptable, adding Pro Polymer is not necessary.

For the Stabilized Vitamin C 20%, you could consider Ascorbyl Glucoside (AA-2G Stabilized Vitamin C) or Ascorbyl Glucoside 20% Gel (MaxActivate™). Note that Stabilized Vitamin C (Natural-C Glycol™) Serum is a ready-made base and generally not suitable for adding other ingredients as it may affect its stability.

Mixing Considerations:

• When adding Azelaic Acid (Liquid Azelaic™), mix it in the final step at a temperature below 40°C. The optimal pH range for this ingredient is 5-11.
• When using Pro Polymer™ (Gel Maker), mix it into the water phase by sprinkling the powder and stirring slowly for 3-5 minutes. Avoid high-speed blending (above 2500 rpm) as it can damage the polymer. It may take time to fully dissolve; leaving it for a day can help. If your formula contains glycerin or propylene glycol (>5%), you can pre-mix the Pro Polymer with them before adding to water.
• If using Ascorbyl Glucoside (AA-2G Stabilized Vitamin C), it is most stable in a pH range of 6.5-6.8. You will need to measure and adjust the pH of your final formulation.
• Ensure the final pH of your formulation is suitable for all active ingredients. The pH range of 6.5-6.8 is compatible with both Azelaic Acid (5-11) and Ascorbyl Glucoside (6.5-6.8).
