Hello, the formula cannot be mixed. Because there are some ingredients such as ascorbic acid , Vitamin B5 need to be dissolved in water. But the formula does not contain water. these ingredients Although soluble in some Glycols, the solubility rate is very low. In addition, members are opted into a high % such as ascorbic acid 20%, so there is no possibility that it will dissolve.

Hello, because using Vitamin C in high quantity, there will be 2 problems. 1. The amount of water (35%) may not be enough to dissolve ascorbic acid 15%. However, members must test it. The team couldn't tell if it dissolved completely or not. Characteristics that occur if incomplete solubility is Sediment is formed in the formula. 2. Satin Cream Maker May be acid resistant of ascorbic acid in high quantity. Members may need to use other aids together. that can tolerate acidity well, for example AnyGel in conjunction with Satin Cream Maker . That's right
