California has two different types of warnings – those for cancer and those for reproductive health effects. Some products have one or the other of these warnings and some products have both warnings. These warnings are required by California labeling law Proposition 65 (or Prop 65 for short), which is meant to notify individuals in California of exposures to Prop 65-listed chemicals. Prop 65 does not ban the sale of any products containing these chemicals; it only requires warnings. While the word chemicals can sound scary, it is important to note that A Prop 65 warning does not automatically mean that the product is unsafe.
