Designated list means the list of chemicals identified as candidate chemicals that exhibit a hazard trait or an environmental or toxicological endpoint that meets the criteria in regulations adopted by the Department of Toxic Substances Control under Health & Safety Code 25251 et seq., published on the Department's internet website. Intentionally added chemical means a chemical a manufacturer has intentionally added to a product that has a functional or technical effect in the product, including components of intentionally added chemicals and intentional breakdown products of an added chemical that also have a functional or technical effect. Stored membership is partial: the PFAS class (DTSC Candidate Chemicals list, CalSAFER record 22892) only; the other candidate chemicals are not enumerated, so "no PFAS" does not mean "no designated chemical".
