For decolourizing of massecuites at sugar crystallization as well as the sugar crystal related hereto (sugar boiling).


    • A high-power reducing agent based on a selected sulfurous compound (sodium hydrosulfite).
    • The decolourizing of the massecuites is due to the reduction of chromophoric groups of sugar by-products.
    • KEBO COLOUR EX decomposes slowly at access of moisture and heat (please refer to remarks "Handling“).

    Dosing, Addition

    Depending on the colour intensity of the massecuites 10 to max. 50 ppm (g/m3) are added. 
    This would mean for a strike of 50 tons a quantity of 0.5 to max. 2.5 kg KEBO COLOUR EX is needed.


        • At access of heat and moisture decomposition takes place by formation of SO2 gas and development of heat. For this reason KEBO COLOUR EX must be protected against moisture and heat.
        • Opened drums have to be well closed again. If a drum catches fire it has to be sorted out and opened to avoid a dynamic pressure.
        • The contents of the drum has to be covered with sand. We recommend CO2 (carbonic acid gas) and powdery extinguishing agents.
        • In case lumps are discovered these have to be immediately eliminated by means of a coarse-meshed screen and sunk into water.
        • When handling KEBO COLOUR EX protective goggles and gloves must be worn. Skin and mucous membrane which have come into contact with KEBO COLOUR EX have to be thoroughly rinsed with water.

              The products shown on our website are only a selection of our entire product range. There is no universal remedy for the rapid removal of impurities. Some can be removed well with alkaline agents, others better in the acidic range. The large variety of conceivable cleaning problems and the large number of additives, inhibitors and ready-to-use cleaning solutions offered by us make it advisable to obtain detailed advice before starting cleaning.
              The same applies to inhibitors, defoamers, scale preventers, corrosion inhibitors, pickling inhibitors, etc. Depending on the plant, material, product and the type of boiler/cooling water is used, different individual challenges arise. We are well equipped for them.

              Talk to us, we will be happy to help!
              On request, we can analyze deposits in our laboratory and develop a cleaning strategy based on our many years of experience, taking into account the conditions on site.
