In order to be sold legally within the European Union, a cosmetic product must comply with the EU Cosmetics Regulation (EC) No. 1223/2009, which sets out a number of requirements relating to the safety, labeling, and packaging of cosmetic products. Additionally, any individual substances used in the cosmetic product must also comply with the EU’s REACH regulation (EC) No. 1907/2006. Failure to comply with these regulations can result in legal penalties, as well as potential harm to consumers and the environment.
