Information regarding mixing Stabilized Vitamin C (Natural-C Glycol™) into cream

Regarding your question about mixing Stabilized Vitamin C (Natural-C Glycol™) into an existing cream, based on the product information, this particular form of Vitamin C is not recommended for adding to other formulations or finished creams.

• Why it's not recommended: Stabilized Vitamin C (Natural-C Glycol™) is designed to be a stable, ready-to-use serum base. Adding other ingredients can disrupt its stability and effectiveness.

If you wish to add a Vitamin C derivative to an existing cream, there are other forms that are more suitable for mixing:

• Perfect-C™ (Ascorbyl Tetraisopalmitate): This is an oil-soluble Vitamin C derivative. It is suitable for mixing into creams, provided the cream has a pH of not more than 6.0.
• Ascorbyl Glucoside (AA-2G Stabilized Vitamin C): This is a water-soluble Vitamin C derivative. It is suitable for mixing into creams that have a pH in the range of 6.5-6.8. Note that mixing this requires careful pH adjustment to maintain stability.

Therefore, you should not mix the Stabilized Vitamin C (Natural-C Glycol™) you have into your cream. Instead, consider using Perfect-C™ or Ascorbyl Glucoside (AA-2G Stabilized Vitamin C) if you want to add Vitamin C to an existing cream, ensuring the cream's pH is appropriate for the chosen ingredient.
