Proposition 65 List Updated – Again

California Prop 65 Updates

Sometimes I feel behind in the regulatory world. It is just a fact that regulations often change faster than one has time to process.  A good case for this is California’s Proposition 65. Not only are there multiple changes for how to represent substances that are on the list, but the list itself changed in May 2018.  For more information on “how to represent” and the August 30, 2018 changeover date, take a look at ICC’s blog found here

To refresh your memory, the Safe Drinking Water and Toxic Enforcement Act of 1986 is the official name for California’s Prop 65.  The list has to be revised and republished at least once per year.  California’s Office of Environmental Health Hazard Assessment (OEHHA) is the agency responsible for Prop 65 implementation.  They consider adding chemicals to the list when some other “authoritative body” makes a determination regarding a substance’s ability to cause cancer, birth defects or other reproductive harm. Shown below are all of the new substances that were added and or removed by month. They are listed by name, type of toxicity and Chemical Abstracts Service Registry Number (CAS).

Now would be a good time to see not only if you are up to date on the new required “warnings” but if any of your products or substances were added to the new list.
