Question

What are the considerations and limitations when adding Ectoin to stabilized vitamin c glycol, specifically regarding solubility and the stability of Vitamin C?

Answer

Based on the information provided, you can add Ectoin to stabilized vitamin C glycol, but only in a small amount, not exceeding 1%. This is because Ectoin dissolves well in water but has limited solubility in other solvents like stabilized vitamin C glycol, which does not contain water.

Adding a small amount (up to 1%) of Ectoin, which has a pH of around 6-8, will have minimal impact on the formula's pH. However, adding more could increase the pH of the formula, which could affect the stability of the Vitamin C.
