Compatibility and Stability of Vitamin C (Natural-C Glycol vs Perfect-C) with Repair Activator
Question
I am developing a formula and would like to mix Repair Activator with Natural-C Glycol. Is this combination stable and compatible for a commercial product?
If they are not compatible, are there any other forms of Vitamin C that can be successfully combined with Repair Activator, considering factors like pH and stability?
Answer
Mixing Repair Activator with Natural-C Glycol
Based on the information, it is generally not recommended to mix Repair Activator with Natural-C Glycol gel for long-term stability or commercial products. This is because Repair Activator has a higher pH (4-5.5) compared to Natural-C Glycol (2-3), and mixing them would increase the pH of the Natural-C Glycol formula. A higher pH can significantly shorten the lifespan and effectiveness of the Vitamin C (L-Ascorbic Acid) in Natural-C Glycol.
Mixing for very short-term personal use (e.g., 1-2 weeks) might not cause noticeable issues, but it is not suitable for developing a stable product for sale.
If you need to mix a Vitamin C form with Repair Activator, the recommended option is Perfect-C. Perfect-C is an oil-soluble Vitamin C derivative (Ascorbyl Tetraisopalmitate) that is compatible with Repair Activator and can be mixed without stability problems related to pH incompatibility, provided the final formula pH is within the recommended range for Perfect-C (5.0-5.5) and other mixing requirements are met.
Other forms of Vitamin C typically have pH limitations that make them unsuitable for mixing with Repair Activator.
