Compatibility of Stabilized Vitamin C Serum and Natto Gum (pH Issue)

Hello!

Mixing Stabilized Vitamin C (Natural-C Glycol™) Serum and Natto Gum is not possible due to their incompatible pH levels.

• Stabilized Vitamin C (Natural-C Glycol™) Serum has a pH in the range of approximately 3-3.5.
• Natto Gum is only stable within a pH range of 4-7. Adding Natto Gum to the Stabilized Vitamin C serum formula will cause the Natto Gum to degrade.

If you wish to add a moisturizer to the formula, we recommend considering the following alternatives:

• Double Hyaluron Liquid: Can tolerate acidity down to pH 3.0. We recommend using 2-3%.
• Vitamin B5 (Panthenol Pro-Vitamin B5): Can be used in formulas with a pH down to 3.5.

Thank you!
