Chemical Selected by OEHHA for Consideration for Listing by the Carcinogen Identification Committee and Request for Relevant Information on the Carcinogenic Hazards of Butyl Benzyl Phthalate

The California Environmental Protection Agency's Office of Environmental Health Hazard Assessment (OEHHA) is the lead agency for the implementation of Proposition 65 . The Carcinogen Identification Committee (CIC) of OEHHA's Science Advisory Board serves as the State's qualified experts and renders an opinion about whether a chemical has been clearly shown to cause cancer . The chemicals identified by the CIC are added to the Proposition 65 list.

OEHHA has selected the chemical below for the CIC's review for possible listing under Proposition 65. OEHHA is initiating the development of hazard identification materials on this chemical.

Chemical Selected for Preparation of Cancer Hazard Identification Materials

This chemical was selected using the procedure described in a 2004 document entitled: “Process for Prioritizing Chemicals for Consideration under Proposition 65 by the State’s Qualified Experts.”

OEHHA selected this chemical from those prioritized by the CIC in 2011. 

Hazard identification materials for butyl benzyl phthalate will be presented at a future meeting of the CIC for Committee review for possible listing under Proposition 65. 

By this notice, OEHHA is giving the public an opportunity to provide information relevant to the assessment of the evidence of carcinogenicity for butyl benzyl phthalate.  Relevant information includes but is not limited to: 

• cancer bioassays
• cancer epidemiological studies
• genotoxicity testing
• other pertinent data on:
  • pharmacokinetics
  • biomarkers
  • effects on biochemical and physiological processes in humans 

Interested parties or members of the public wishing to provide such information should send it to the address given below. 

The publication of this notice marks the start of a 60-day data call-in period, ending on Tuesday, January 22, 2013.  The information received during this period will be reviewed and considered by OEHHA as it prepares the cancer hazard identification materials on butyl benzyl phthalate. 

Hazard identification materials are made available to the public for comment prior to the CIC’s consideration of the chemical for possible listing.  The availability of hazard identification materials will be announced in the California Regulatory Notice Register and on OEHHA’s website.  The time, date, location, and agenda of the CIC meeting where a chemical will be considered for listing will be published in the California Regulatory Notice Register and posted on OEHHA’s website. 

We encourage you to submit relevant information on this chemical in electronic form, rather than in paper form.  Submissions transmitted by e-mail should be addressed to P65Public.Comments@oehha.ca.gov.  Please include “butyl benzyl phthalate” in the subject line.  Submissions in paper form may be mailed, faxed, or delivered in person to the addresses below:
