Herbal Essences shampoo with CSI and sodium benzoate
This is a Shampoo from Herbal Essences. The main anionic surfactant is CSI and the preservatives are sodium benzoate and sodium salicylate. As per my information these preservatives don’t work in pH above 5 and this surfactant doesn’t work in pH below 6. So
does CSI work properly in pH 5 or this shampoo has high pH?
