DERVAL POWER is even better!

KROESLER has once again improved the formula of the well-known basic washing enhancer DERVAL POWER.

Since 2011, the distribution system of the optical brightener has been improved for its even more effective effect. As a result, the color of the DERVAL POWER has also changed from yellowish-green to amber with the opalescent greenish-yellow glow that you know well.

All other properties of DERVAL POWER, including concentration, recommendations for use, safety measures, etc. remained unchanged.
