On October 18, 2013, the California Department of Toxic Substances Control (DTSC) released an updated “Initial Candidate Chemicals List” – a list of chemicals that will be the first to receive the DTSC’s attention when it identifies “Priority Products” for regulation in 2014 under the new Safer Consumer Products Regulations.
The DTSC first released the list of “Initial Candidate Chemicals” on September 26, 2013, four days before the Safer Consumer Products Regulations implementing California’s Green Chemistry Initiative went into effect. The Regulations require the list to be updated periodically. With the update, the number of “Initial Candidate Chemicals” drops from 164 to 155.
The following chemicals were removed from the updated “Initial Candidate Chemicals List,” although each still appears on the “Candidate Chemical List”:
- 4-Tert-Octylphenol; 1,1,3,3-Tetramethyl-4-butylphenol
- Bisphenol A diglycidyl ether polymer; [2,2′-bis(2-(2,3-epoxypropoxy)phenyl)-propane]
- Bisphenol B; (2,2-Bis(4-hydroxyphenyl)-n-butan)
- Bromate
- Dibromoacetic acid
- Dichloroacetic acid
- Dicyclohexyl phthalate and metabolite
- Diethyl phthalate and metabolite
- Nonylphenol, nonylphenol ethoxylates (NP/NPEs) (and related substances)
- Parabens
In addition, Bis(2-chloro-1-methylethyl)ether,technical grade was added to the Initial Candidate List.

Chemicals are placed on the “Initial Candidate Chemicals List” if they have both a hazard trait and environmental or toxicological effects. Chemicals that have only a hazard trait or only environmental or toxicological effects are placed on the more extensive “Candidate Chemicals List,” of which the “Initial Candidate Chemicals List” is a subset.
The updated list of “Initial Candidate Chemicals” is significant in that it removes parabens as a priority chemical. Parabens are commonly used in cosmetics as a preservative. The family of parabens on the “Candidate Chemicals List” includes Butylparaben (includes n-butylparaben and isobutylparaben); Ethyl paraben, Ethyl 4-hydroxybenzoate; Methylparaben; Methyl p-Hydroxybenzoate; and n-Propylparaben.
What this means is that parabens will not be targeted by DTSC as a potential “chemical of concern” when the DTSC identifies priority products containing chemicals that will need to be subject to an alternatives analysis and regulatory response. The DTSC must propose its list of up to five priority products, or categories of priority products, for regulation by April 1, 2014. However, parabens continue to appear on the DTSC’s exhaustive list of more than 1,016 “Candidate Chemicals” so they may yet draw attention from the DTSC.
