Candidate Chemicals List Certain Acids and Bases

DTSC proposes adding 12 acids and bases to the Candidate Chemicals List due to concerns about widespread exposures and potential for adverse impacts. The rationale for this proposal is detailed in the technical document.

Adding certain acids and bases to the Candidate Chemicals List does not create new regulatory obligations.

Adding a chemical to the Candidate Chemicals List does not create any new regulatory obligations or regulated entities. The presence of a chemical on the Candidate Chemicals List allows DTSC to evaluate product-chemical combinations containing that chemical, potentially leading to Priority Product regulations. New regulatory requirements result only when DTSC identifies and lists a Priority Product under California Code of Regulations Title 22, Section 69503.5.
