Cream Formulation: Texture Adjustment and Zinc Oxide White Cast

Asked by: borifle On: September 18, 2015 Product Type: Cosmetics

Question

I am developing a cream and need advice on three points:

  • Texture Adjustment: How can I make the cream more liquid? I'm considering replacing Silicone Gel 10% with Cyclomethicone 10%. Will this work?
  • Water Drop Effect: How can I enhance the "water drop" effect? (The answer suggests removing Dimethicone (light) 10% and adding 10% water).
  • White Residue from Zinc Oxide: I am getting white residue on my fingers. The staff indicated this is likely due to the regular Zinc Oxide. How can I resolve this issue and prevent the white cast? (The staff recommended using Zinc Oxide 200nm EasyDisperse™).

Answer

Based on the conversation:

  1. Making the cream more liquid: Yes, replacing Silicone Gel 10% with Cyclomethicone 10% should result in a more liquid texture.
  2. Enhancing the water drop effect: Yes, increasing the water content (e.g., by removing Dimethicone (light) 10% and adding 10% water) should make the water drop effect more noticeable.
  3. White residue: The staff identified the regular Zinc Oxide (not the EasyDisperse™ version) as the likely cause of the white residue on your fingers. To resolve this, you should replace the regular Zinc Oxide with Zinc Oxide 200nm EasyDisperse™.

Using the EasyDisperse™ version of Zinc Oxide is recommended for better dispersion and reduced whitening, which should help eliminate the white residue issue you are experiencing.
