Many of our products can preserve themselves naturally, but a couple of Ecover products do contain preservatives as well. At Ecover, we use consciously chosen ingredients that are readily biodegradable. These ingredients tend to be more prone to bacterial growth which affects performance. We, therefore, need to use preservatives in our products to ensure the ingredients do not degrade. We mostly use natural preservatives, such as lactic acid, and nature identical products like sodium benzoate. We always mention preservatives on the label, if it’s not on the label, it’s not in the product.
