Most market participants have used almost exclusively tropical palm kernel oil and, to a lesser extent, coconut oil in the production of surfactants. However, surfactants based on tropical oils destroy the rainforest’s biodiversity in the long term and even the rainforest itself, the green lungs of the Earth.
Therefore, in its biodiversity protection efforts, Werner & Mertz relies not on the use of tropic oils alone and continuously raises the portion of surfactants based on European oil plants such as rapeseed, olive, linseed and sunflowers. Rapeseed and sunflower oils come from German, Poland and France; linseed oil from France and Belgium and olive oil from southern Europe, Spain, Italy and Greece. None of the oils used competes with food production.
