Formulation Issue: Azelaic Acid Cream with Satin Cream Maker

Hello, based on the information you provided and the staff's reply:

The reason your formula didn't result in a cream texture, but instead became lumpy and watery, is due to Azelaic Acid. Azelaic Acid is an electrolyte, which makes it difficult for the emulsifier (Satin Cream Maker) to create a stable cream texture.

The suggested solution from the staff is:

• Increase the amount of Satin Cream Maker: Increase from 1% to 1.5-2.0%.
• Adjust the mixing procedure:
  • Mix all other ingredients as usual until the cream base is formed.
  • Keep Azelaic Acid to add in the final step.
  • Gradually add Azelaic Acid little by little, mixing or blending well after each addition.
  • Observe the texture. If it becomes significantly thinner, add a small amount of additional Satin Cream Maker and mix or blend again to rebuild the texture.
  • Repeat this process until all Azelaic Acid is incorporated without the texture becoming too thin (which would lead to separation).

Hope this helps!
