California Proposition 65: Reformulation of Chemicals in Consumer Goods

SafeGuardSHardgoods, Food Contact MaterialAugust 05, 2022

SG 093.22

Multiple settlements have been reached for a variety of consumer goods containing Prop 65 chemicals. Many of these agreements allow a Prop 65 warning as an alternative.

California Proposition 65 (Prop 65) is the ‘Safe Drinking Water and Toxic Enforcement Act of 1986’, a ballot initiative passed overwhelmingly by Californian residents in November 1986. It requires the state to publish a list of chemicals that are known to cause cancer, birth defects and/or reproductive harm. First published in 1987, the list has evolved to include almost 900 chemicals.

In Prop 65, one important provision for companies doing business in California is to provide a clear and reasonable warning before knowingly and intentionally exposing anyone to a listed chemical. Unless exempt, businesses have 12 months to comply with this requirement once a chemical is listed.

In this communication, we summarize multiple settlements involving a variety of consumer products containing bisphenol A (BPA, Table 1), diethanolamine (DEA, Table 2), formaldehyde (Table 3), lead (Table 4), DEHP (Table 5), DIDP (Table 6), DINP (Table 7), DBP and DEHP (Table 8) and six phthalates (Table 9).

It is interesting to note that there was a judgment for BPA in socks, in which the reformulation requirement limited BPA to a maximum of 1 ppm and prohibited the use of another phenol as a BPA substitution (SafeGuardS 083/22). A similar case was established for BPA in sous vide containers, where the parties settled on a reformulation requirement as BPA, Bisphenol S (BPS), Bisphenol F (BPF) and Bisphenol AF (BPAF) not detectable. BPA analogs as BPS, BPF or BPAF are currently not on the Prop 65 list of chemicals (Table 1, entries 1 and 2).

A Prop 65 settlement is a consent agreement between the parties named in the settlement and a party not named in a settlement is not bound by that settlement.
