Household Care A difficult market for green products

Products with generally low emotional-closeness to end-users.

The prejudice: Green products lack in power

In the area of Household Care the ecological trend is lagging behind.

Due to bad experiences customers hesitate to choose green products.

Green & powerful.

We created a biosurfactant that customers actually want:REWOFERM® SL.
