In the interest of sustainability, we always weigh very carefully between the lowest environmental impact and health compatibility. Some everdrop products contain synthetic ingredients – but these are not automatically worse for humans and the environment than natural ingredients. Example fragrances: Here, synthetic substances are often 'better' than natural ones because their production explicitly avoids substances that have a significantly worse/higher risk or allergy potential. Also, a purely natural fragrance that smells particularly long-lasting and intense might be harder to degrade. Thus, natural fragrances are often worse for the environment and people than synthetic ones.
Other non-natural ingredients we use are so-called complexing agents (softeners), preservatives, and flow agents – which are not automatically 'synthetic' but at least 'partially synthetic'. The background is that these are not present in nature 1:1 or are synthetically replicated to protect nature due to the required quantities.
In our glass cleaner, there is also a synthetically produced surfactant, and in our products with 'active oxygen' (oxygen-based bleach), TAED is included as a bleach activator based on petroleum components. This is necessary so that we can achieve optimal effectiveness at cold application and washing temperatures in the interest of sustainability.
