The aquatic life warning is an EU legal requirement for concentrated soaps and detergents.
Our formulation is incredibly concentrated to minimise carbon transport emissions. If we diluted our product down with fillers (as many brands do) it would not require this label - you would however have to use more product per clean and your carbon footprint would increase. Once diluted for use, the warning no longer applies.
It is predominantly there to provide instruction should there be a catastrophic / undiluted / concentrated exposure to the environment whereby a large quantity entered the water ways, for example as the result of an industrial accident. This warning is based on a very unrealistic scenario.
