Candidate Chemical Terms
| Term | Definition |
| Authoritative Lists: | Twenty-three authoritative lists are identified in the Safer Consumer Products Regulations (Cal. Code Regs., tit. 22, section 69502.2(a)). They are used to identify the Candidate Chemicals in the Informational List. |
| Candidate Chemical: | The regulations define a Candidate Chemical as a chemical that exhibits a “hazard trait and/or an environmental or toxicological endpoint” and is either: (1) found on one or more of the authoritative lists specified in section 69502.2(a) of the regulations; or (2) listed by DTSC using the criteria specified in section 69502.2(b). |
| Candidate Chemical List: | The list of chemicals DTSC’s SCP program must use to identify the chemical in a product-chemical combination or Priority Product. |
| Chemical Abstracts Service Registry Number (CAS RN): | The CAS RN is a numeric identifier for chemicals assigned by the CAS Registry. |
| Chemical of Concern: | A Chemical of Concern is a Candidate Chemical that is the basis for a product being listed in regulations adopted by DTSC as a Priority Product. See section 69501.1(a)(21) for the regulatory definition. |
| Exposure Potential List: | Authoritative lists identified in 69502.2(a)(2) as they were developed based on exposure potential concerns. |
| Group: |
Some Candidate Chemical groupings on the Informational List have been taken directly from an authoritative list (e.g., “Gas oils” on the PBiT List from Environment Canada). DTSC has grouped other chemicals on the Informational List according to recognized similarities (e.g., PCBs, dioxins, and furans). |
| Hazard Trait: |
This is when the intrinsic property of a chemical cause adverse effects in humans, animals, or in ecological communities. See definition in section 69501.1(a)(36), which references the definition in Chapter 54 of Title 22 of the California Code of Regulations. |
| Informational Candidate Chemicals List: | This is DTSC’s compilation of all the chemicals on the authoritative lists and their respective hazard traits. |
| Initial Candidate Chemicals List: | The SCP regulations require that any Priority Product DTSC identifies in the initial Priority Product list (or any revisions to the list that are adopted prior to January 1, 2016) must include chemicals from the lists identified in section 69502.2(a)(1) and (2). For the convenience to stakeholders, we’ve named this the “Initial Candidate Chemicals List.” An archived list of Candidate Chemicals is available in Excel and PDF. |
