    Product description:

     

    GLDA-Na4 is a environmental friendly and biodegradable chelating agent based on natural source. As an alternative to phosphonates, NTA and EDTA, the chelating GLDA-Na4 is used in industrial and household cleaners for improving the detergency.

    GLDA-Na4 is a strong chelating agent for metal ions, which can form stable and water-soluble complex compounds. It has an exceptional high solubility in a wide pH-range.

    It does not sensitize human skin, provides enhanced biocidal boosting power and improved biodegradability properties.
