We have upgraded the formula of our Ecover Zero Washing-up Liquid to bring it in line with the performance of our main Ecover washing-up liquid. The product is still formulated to minimise the risk of allergies and is still suitable for sensitive for skin. We have added the following ingredients: Glycereth -6 Cocoate – a surfactant derived from palm or coconut oil, Coco-glucoside – a surfactant derived from fermented glucose or coconut oil, Sodium octyl sulphate – surfactant derived from kernel or coconut oil, Alcohol denat. – ethanol derived from consciously chosen sources that helps to preserve the formula and also helps control viscocity, and Citric acid – derived from fermented glucose citric acid helps to regulate the PH level to ensure it works properly.
