Banned cosmetic ingredients from 2025 in California (US state): The 12 numbered ingredient groups of Health and Safety Code 108980(a) (phthalates DBP and DEHP, formaldehyde, paraformaldehyde, methylene glycol, quaternium-15, mercury, isobutylparaben, isopropylparaben, m- and o-phenylenediamine and their salts, and 13 listed PFAS and their salts) when intentionally added to a cosmetic product. The statute prints CAS 355-76-2 for nonadecafluorodecanoic acid (HSC 108980(a)(12)(H)); that number fails the CAS check digit, so the registry number 335-76-2 is listed as well (deliberate addition).
“a person or entity shall not manufacture, sell, deliver, hold, or offer for sale in commerce any cosmetic product that contains any of the following intentionally added ingredients:”

The statute prints CAS 335-76-2 for nonadecafluorodecanoic acid (21-259.2(b)(12)(viii)); the group uses that number as printed (the California text prints 355-76-2 for the same substance).
