pH of Vitamin C Ester in Cream Formulations

As the staff correctly informed, oil-soluble ingredients like Vitamin C Ester (Ascorbyl Palmitate) do not have a pH value themselves, as pH is a measure of acidity or alkalinity in water.

However, even though the ingredient itself doesn't have a pH, the pH of the overall cream formulation containing this ingredient is important for the stability of the formula, especially if the formula contains a water phase.

For oil-soluble Vitamin C esters, such as Perfect-C™ (Ascorbyl Tetraisopalmitate), another highly effective type of Vitamin C Ester, the recommended pH for the formulation is typically in the range of 5.0-5.5 or not exceeding 6.0 to help maintain the stability of the Vitamin C in the formula.

Therefore, while Ascorbyl Palmitate itself does not have a pH, controlling the pH of the cream formulation to be within an appropriate range (such as 5.0-6.0, based on recommendations for similar Vitamin C esters) will help ensure the stability and effectiveness of the Vitamin C Ester in your product.
