Under Phosphate Restrictions, How Can MGDA Solid Powder Help Companies Comply?

In recent years, many regions across China have introduced total phosphorus discharge controls for detergents, greatly limiting the use of phosphorus-based additives in daily chemical formulas. At the same time, EDTA faces increasingly strict regulatory pressure in markets such as the European Union because it is difficult to biodegrade.

Against this backdrop, MGDA, as a new-generation green chelating agent, has become an ideal alternative to traditional phosphorus-based additives and EDTA. Research data shows that MGDA can achieve a biodegradation rate of up to 100% within 21 days, while EDTA cannot be biodegraded by microorganisms even after 28 days. MGDA is phosphorus-free, non-toxic, and non-irritating to eyes and skin, avoiding eutrophication risks at the source.

Shandong Kairui Chemistry’s MGDA solid powder has an active content of ≥90% and is particularly suitable for solid detergents and dishwasher tablet formulas that require dry blending. In heavy metal pollution treatment, MGDA also performs well—its removal efficiency for nickel from river sediment follows the order MGDA > GLDA > EDTA, and its copper removal efficiency is comparable to GLDA and better than EDTA.

Shandong Kairui Chemistry is located in the Xuecheng Chemical Industrial Park, Xuecheng District, Zaozhuang, Shandong. It is a professional source manufacturer of green chelating agents, and its products meet the requirements of dual-carbon goals and total phosphorus discharge control.
