EDTA
Hi all,
I would like ask if anyone had counter the same issue. Previously, I am formulating face cleanser, the texture was moisturising enough. Unfortunately, the colour of products become decolourised over the time. Therefore, I decided to add EDTA (0.1%). Then, suddenly, I received a complaint, said that the cleanser not same a previous. His skin felt dry. So, while try to find the best solution, I would like to ask if anyone experienced the same? Does adding a bit EDTA really increase the irritation to the skin? Feel free to share your thought.
Thank you!

For new formula, we make little change, they put glycerin in surfactant system. I suspect too if change glycerin in surfactant phase will boost up surfactant power and make the feel become drier.
