Heptagluconic acid (hereinafter referred to as “HGA acid”) is an organic complexing agent in fertilizers containing micronutrients. HGA acid is effective, biodegradable, has good stability over a wide range of pH values, and high solubility in water. The use of HGA has been authorized for many years in Spain, and no harm to the environment or human health has been reported during that time [COMMISSION REGULATION (EU) 2016/1618 of 8 September 2016].
