MGDA-Na3 Technical Data | Biodegradability & REACH Compliant

Q1: What is the biodegradability profile of MGDA-Na3?

MGDA-Na3 is classified as "Readily Biodegradable" according to the OECD 301B test method. It breaks down into non-toxic components within 28 days in wastewater treatment environments. This makes it compliant with strict international environmental regulations and ideal for eco-certified products (such as EU Ecolabel or US EPA Safer Choice).

Q2: How does MGDA-Na3 perform under high-temperature and extreme pH conditions?

MGDA-Na3 exhibits exceptional thermal stability (effective above 100°C) and remains chemically active across a wide pH range, typically from pH 2 to 14. This robust profile allows it to perform in heavy-duty alkaline degreasers and acidic descaling agents where other organic chelants might fail.

Q3: What are the standard packaging and storage requirements for MGDA-Na3?

We typically supply MGDA-Na3 as a 40% aqueous solution in 250kg drums or 1250kg IBC tanks. It should be stored in a cool, dry place away from direct sunlight. Due to its stable chemical nature, it has a shelf life of approximately 12 to 24 months when kept in original, sealed containers.
