Sulphuric Acid [H2SO4]

The European Sulphuric Acid Association (ESA) is the Sector Group of Cefic representing the European Sulphuric acid industry. Though not directly involved in the REACH consortium itself, ESA follows closely its activities, collaborating with the consortium on technical files related to substances’ registration. ESA is the reference point for regulatory and policy matters affecting the European Sulphuric acid industry.

ESA focuses its activities mainly on the following three substances (see below)
