Thank you very much from the team. From what Staff suggested, can I change as follows? 1. Use
Light Cream Maker instead of
SiliSolve Plus using base 2% as before, mixed in oil 2. I can adjust the pH of
glycolic acid using paper to measure pH and NaOH first, then mix. with
propolymer like this? or if not I will switch to
AnyGel as suggested by modifying as follows, use
AnyGel instead of
Pro Polymer In the formula, use 1.5% as recommended, change to the following: 87.3 g of water divided into 20 g to dissolve
glycolic acid , the remaining 67.3 g of water is heated, then add
EDTA down Go 0.2 g and gradually add
AnyGel into 1.5 g to dissolve into a homogeneous and then add
glycolic acid added to the solution, stirred to combine, then add 1 g of preservative 3. Switch to Use
Complex Salicylic Acid prepared 100 g with the following ingredients: RO 98.8 g +
EDTA 0.2 g +
Complex Salicylic Acid 5g +
Mild Preserved Eco 1 g 4. Can use use
Complex Salicylic Acid was used instead of 5% of the total. (get 2% active
BHA ) and combined with other ingredients
วัดค่า pH first to obtain 3 by using NaOH and adding it to
