Blog: California looks to expand regulation of microplastics and PPD derivatives
California has begun the public process for a potential regulatory proposal expanding the list of chemicals that may be regulated under its Safer Consumer Products Program (SCP). The California Department of Toxic Substances Control (DTSC), part of the California Environmental Protection Agency, has proposed adding microplastics and para-Phenylenediamine (PPD) derivatives to its Candidate Chemicals List (CCL) in an attempt to control their impact on human health and the environment. PPD derivatives are a family of chemicals used in a variety of industrial applications. The only PPD derivative currently on the CCL is 6PPD, a substance used to prevent deterioration of motor-vehicle tires but that has also been found to hurt certain species of salmon when it transforms into a toxicant known as 6PPD-quinone.
