The world of Dissolvine® chelates

We supply the following Dissolvine® chelates: GLDA, MGDA, EDTA, DTPA, HEDTA, NTA, PDTA, EDG and Glucoheptonate. EDTA is generally the preferred choice , but specific applications may require other chelating agents.

Common specific properties of these molecules:


The strong and green chelate in our product range, marketed under the trade name Dissolvine® GL. A safe and readily biodegradable chelating agent that can be used as alternative for NTA, EDTA, phosphates and phosphonates, especially in cleaning applications.  It has a high solubility over a wide pH range. The major part of the molecule originates from a natural sustainable source.

MGDA is a fast-working, strong builder with excellent ecological properties, being readily biodegradable and not labelled as dangerous. This makes MGDA an ideal replacement for ingredients under regulatory pressure, such as phosphates (which is banned in various regions due to water eutrophication) in automatic dish washing (ADW) and laundry. It is a drop-in replacement for NTA in industrial and institutional cleaners.

GlucoheptonateA biodegradable chelating agent based on a carbohydrate. It is generally weaker than the aminopolycarboxylates (APCs) mentioned above. However, it exhibits an exceptional chelating ability for iron and other transition metal ions at high pH. As with GLDA, the major part of the molecule originates from a natural sustainable source.
       HEDTAA chelating agent with similar efficacy to EDTA. Particularly useful when high solubility is needed at low pH and for stabilizing iron ions at high pH.
        EDTAThe most widely used, strong, cost effective and general purpose chelating agent.
        DTPARecommended when a stronger chelating agent is needed, such as during peroxide bleaching of pulp. It remains more effective under oxidizing conditions. It is also especially suitable for descaling in oilfield applications.
