Adjusting pH and Adding Ingredients to Natural-C Glycol™ Serum
คำถาม
I have the Natural-C Glycol™ serum.
- How can I adjust the pH if it measures below 3.0?
- Can I add other ingredients, such as Alpha Arbutin, to this serum? I am concerned about the stability of the Vitamin C in the formula if I make modifications.
คำตอบ
Based on the provided conversation:
To adjust the pH of Natural-C Glycol™ serum if it is less than 3.0: You can add Triethanolamine (a mild base) to the formula. Add it gradually, mixing thoroughly after each addition, and measure the pH until it reaches the desired level of 3.0. Important: Do not use more than 5% Triethanolamine in the formula, as it may cause skin irritation.
Regarding adding Alpha Arbutin or other ingredients: The staff strongly advises against adding any additional ingredients or modifying the Natural-C Glycol™ serum formula, especially for beginners. Modifying the formula requires expertise to ensure stability, and incorrect adjustments could cause the Vitamin C in the serum to degrade.
