About formulas with vitamin c

Postby k.nannapass » Fri Apr 06, 2018 2:28 pm

Hello, please ask the knowledgeable people and the staff if the formula below can be done or not. focus on whiteness Vitamin C L-ascorbic acid type standard 15% Vitamin E 1% EDTA 0.2% Xanthan Gum 2% water, the rest because there are already other moisturizing lotions. So do not focus on the moisture in this formula. Then focus on using it quickly to avoid oxidation, so don't put Ferulic Acid Can you please advise? I need a recipe with less ingredients. Thank you.

Hello Xanthan Gum Introduction Try to use only 1%. Using 2% will result in excessive thickening. Vitamin E 0.1% recommended. Use more. This will make the formula sticky. Other parts can be mixed. But the life of the formula will be short. Due to reasons as members already know about the oxidation of Vitamin C when in water.
