Silicone/Oil Cream Separation Issue and Emulsifier Recommendation

Based on the information provided and the staff's response, the reason your cream is separating is likely because the SiliSolve™ emulsifier you used is primarily designed for water-in-silicone emulsions and can only handle a small amount of oil (less than 3%). Your formula contains 3% Avocado Oil and 2% OMC, totaling 5% oil, which exceeds the capacity of SiliSolve™ to keep the oil phase stable within the silicone gel without water.

To fix this issue and prevent separation while keeping your formula water-free, the staff recommends using SiliSolve Plus™. This emulsifier is designed to stabilize formulations containing oil and silicone phases (and water, although not present in your formula).

Here is the recommended adjustment based on the staff's advice:

• Replace SiliSolve™ with SiliSolve Plus™ at an initial concentration of 1%.
• Increase the concentration of Silicone Blender from 2% to 3%.

The staff also provided mixing instructions:

1. First, blend the gel and liquid ingredients (Silicone Gel, Cyclomethicone, OMC, Avocado Oil, SiliSolve Plus™, Silicone Blender) until well combined.
2. Then, add the powder ingredients (Titanium Dioxide, Silk Mica Powder, Zinc Oxide) and blend again until everything is uniformly dispersed.

This adjustment should help emulsify the oil phase within the silicone base and prevent the separation you are experiencing.
