Question
I want to add Centella Asiatica Extract (Madecassoside) to Stabilized Vitamin C (Natural-C Glycol™) Serum. Is it possible to mix these ingredients? What is the recommended usage percentage for Centella Asiatica Extract in this type of serum? Do I need to add a thickener, and if so, will it affect the stability of the Vitamin C?
Answer
Based on the staff's reply:
- Centella Asiatica Extract (Madecassoside) can be added to Stabilized Vitamin C (Natural-C Glycol™) Serum in small amounts (1-2%).
- If they don't mix well, heating to 50-60°C might help.
- A thickener is not needed in this case.
- Adding a thickener might cause stability issues with the Vitamin C in the formula, so testing is required if you choose to add one.
