Preventing Oxidation in Your Vitamin C Serum

Yes, adding ActiveProtec™ OX can help prevent further oxidation and discoloration in your serum containing L-Ascorbic Acid and Perfect-C™.

Here's why:

• ActiveProtec™ OX is specifically designed as a high-performance antioxidant blend that helps prevent the deterioration and discoloration of ingredients, including various types of Vitamin C.
• Your serum contains L-Ascorbic Acid, which is known to be unstable and prone to oxidation, leading to the yellowing you observed. While Perfect-C™ (Ascorbyl Tetraisopalmitate) is more stable, the L-Ascorbic Acid component is likely the main cause of the color change.
• You are already using Disodium EDTA, which is a chelating agent that helps by binding to metal ions that can accelerate oxidation. However, your current concentration of 0.05% is below the generally recommended range of 0.1-0.2% for Disodium EDTA.

How much ActiveProtec™ OX to add?
The recommended usage rate for ActiveProtec™ OX is 0.1% to 1.0% of the total formula. You can start within this range.

Important Considerations:

• ActiveProtec™ OX is mixed into the water phase of the formula.
• The description for ActiveProtec™ OX mentions that the formulation should ideally be above pH 4. L-Ascorbic Acid is typically most effective at a lower pH (often below 4). You should check the pH of your final serum to ensure compatibility, although ActiveProtec™ OX is stated to protect Vitamin C.
• Adding ActiveProtec™ OX will help prevent future oxidation, but it will not reverse the yellowing that has already occurred in the serum.

By adding ActiveProtec™ OX, you are introducing additional antioxidant protection specifically targeted at stabilizing Vitamin C, which should improve the shelf life and color stability of your serum.
