Recently, the Center for Environmental Health (CEH) in the United States has charged over 50 companies for failing to warn about the exposure risks of Bisphenol S (BPS) in paper receipts as required by California Proposition 65. Notices of violation were issued, and there are plans to sue these companies under Proposition 65. According to this law, businesses that fail to comply with the warning requirements may face severe legal consequences, including but not limited to fines and injunctions.

6PPD, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine, with CAS number 793-24-8, serves as an antioxidant and antiozonant in tires, playing a crucial safety role by protecting tire components from erosion by ozone, oxygen, and other harmful factors. However, as tires wear against the road surface during driving, particles containing 6PPD are released, which can transform into the highly toxic 6PPD-quinone upon reaction with ozone, posing risks to aquatic life.
