Question
I am formulating a lotion containing Phytosphingosine SA, Sym-White, and Activated Resorcinol.
- What is the recommended usage rate for Phytosphingosine SA?
- How should I incorporate Sym-White into the formula, especially regarding the oil phase?
- Is it effective or necessary to use Activated Resorcinol together with Sym-White?
Answer
Regarding your lotion formula, based on the staff's feedback, here are the suggested adjustments:
- Phytosphingosine SA: Reduce the usage rate to 0.1-0.2%. The current 1.0% is higher than recommended.
- Sym-White: Add this ingredient at the final step of the formulation process and mix thoroughly. Do not include it in the oil phase from the beginning, even though it can dissolve in oil.
- Activated Resorcinol: It is not necessary to use Activated Resorcinol together with Sym-White. They are from the same family with similar mechanisms, so using them together may not provide increased effectiveness.
