Questions on Ingredient Usage, pH Adjustment for Vitamin C, and Manufacturing Services
คำถาม
Could you clarify the correct usage rate for Activate-Powder Base, as the product page states 1-50% but an example formula shows 80%? Also, is pH adjustment necessary when formulating with L-Ascorbic Acid (Vitamin C), and does the company offer manufacturing services for formulas using Activate-Powder Base?

Formulation Questions
Here are the answers to your questions:
Activate-Powder Base Usage Rate: The recommended usage rate of Activate-Powder Base is 1-50% in the final formula, which includes both the Active Base section and the water gel section. The example formula showing 80% Activate-Powder Base is referring to the composition of the concentrated Active Base itself, which is then used at a lower percentage (1-50%) when mixed with the water gel base to create the final product. So, the 1-50% is the correct usage rate for the Activate-Powder Base component within the complete formulation.
pH Adjustment for L-Ascorbic Acid: Yes, when using L-Ascorbic Acid (Vitamin C), it is necessary to adjust the pH of the final formula. The recommended pH range for L-Ascorbic Acid formulas is between 2.0 and 4.0. Please note that the FDA requires cosmetics applied to the skin to have a pH of at least 3.5.
Manufacturing Services: I can provide technical information about product formulations, but I do not have information about manufacturing services offered by the company. Please contact the company directly for inquiries regarding manufacturing.
