On April 20, 202, the European Chemicals Agency (ECHA) opened a consultation on Austria’s proposal for harmonized classification and labeling (CLH) of Maleic Acid, a buffering agent.
Maleic acid (CAS No.110-16-7, EC No.203-742-5, INCI: Maleic Acid) is an ingredient listed in the Cosing, with the function: Buffering.
The substance is not currently regulated by European Cosmetics Regulation 1223/2009.
It is listed in Annex VI/607-095-00-3 to European CLP Regulation 1272/2008, with the following classifications.
• Acute Tox. 4*, H302 - Harmful if swallowed.
• Eye Irrit. 2, H319 - Causes serious eye irritation.
• STOT SE 3, H335 - May cause respiratory irritation.
• Skin Irrit. 2, H315 - Causes skin irritation.
• Skin Sens. 1, H317 - May cause an allergic skin reaction.
Austria proposes to classify the substance as follows.
