This page is to inform and educate California consumers only.


The State of California requires specific warnings to consumers about products that contain chemicals on the California Office of Environmental Health Hazard Assessment (OEHHA) list of substances that are labeled by OEHHA as carcinogens (substances that can cause cancer) or are called reproductive toxicants (substances believed to cause reproductive harm). In 1986 the voters of the State of California adopted the Safe Drinking Water and Toxic Hazard Enforcement Act (so-called “Prop (or Proposition) 65”). Prop 65 authorized the establishment of the Office of Environmental Health Hazard Assessment, whose mission it is to identify and list substances it believes are hazards to the health of California residents.

The official web site of OEHHA can be reached through the following link: California Prop 65 Web Site

Types of Substances Listed

Substances can either be added to the list or removed from the list based upon scientific testing or a declaration by some authoritative body or group. Currently there are in excess of 770 substances listed by OEHHA.These substances range from naturally occurring substances such as vitamins, minerals, natural human hormones, and more to synthetically produced substances such as many chemicals used in food colorings, hair dyes, cosmetics, automotive fuels, synthetic hormones for human use, and more. Natural progesterone is listed as progesterone. While it is identical to human progesterone, it is nonetheless on the Prop 65 List as a substance “known to the State of California to cause cancer.”

Prop 65 Requirement:

California's Prop 65 requires consumer warnings in a variety of acceptable formats; however, there are some specific exemptions to this requirement [which really make no sense, but it's the law]. While Kokoro, LLC is EXEMPT from warning requirements, some of our resellers may, in fact, not be. To this end, we provide special warning labels to these retailers. "Stand-alone" warning labels require the following statement: This product contains a chemical known to the State of California to cause cancer. Where the reseller provides a "master warning message," the language on the label can vary as long as the information is available to the consumer. The purpose of this page is to provide that information to California residents.
