1. What is the solubility of kojic acid Palmitate Powder?

The oil phase dissolves, kojic acid dipalmitate is difficult to add to the formulation, and crystal precipitates easily.

To solve this problem, it is recommended to add isopropyl palmitate or isopropyl myristate to the oil phase containing

kojic acid dipalmitate, and heat the oil phase to 80 ° C, and keep it for 5 minutes until the kojic acid The palmitate

is completely dissolved, then the oil phase is added to the water phase and emulsified for about 10 minutes.

The pH of the end product obtained is usually around 5.0-8.0.

4. How about the amount of kojic acid DP added?

1-5%

5. Function:

* Whitening:
