Adding PE-1 Aqua (Oil) to Silicone Serum Formulation: SiliSolve vs SiliSolve Plus
Question
I am trying to formulate a silicone-based serum containing Cyclomethicone, water, and water-soluble active ingredients. I want to add PE-1 Aqua (which is an oil) to this formula.
I am currently using SiliSolve as the emulsifier. Can PE-1 Aqua be added to this formulation using SiliSolve? If not, what is the recommended emulsifier and formulation approach?
Answer
Regarding your question about adding PE-1 Aqua to your serum formulation using SiliSolve, Cyclomethicone, water, and water-soluble active ingredients:
Based on the information provided by the staff:
- PE-1 Aqua is an oil.
- SiliSolve is not designed to emulsify oil in a silicone base.
Therefore, you cannot add PE-1 Aqua to your current formulation using SiliSolve.
If you wish to include oil-based ingredients like PE-1 Aqua in a silicone-based serum, the staff recommends using SiliSolve Plus instead of SiliSolve, as SiliSolve Plus can emulsify both water and oil in silicone.
An example formulation provided by the staff using SiliSolve Plus is:
- SiliSolve Plus: 0.5-1% (recommended 0.7-0.8%)
- Cyclomethicone: 10%
- PE-1 Aqua: 3-4%
- Water and water-soluble active ingredients
This alternative formulation allows for the inclusion of PE-1 Aqua to potentially enhance absorption.
