• The Summary Report, chemical lists, sponsoring organizations and sponsored chemicals lists have been updated and is current as of May 28, 2004.
  
  Because the file is significant in size, we strongly encourage users to download the pdf version of the Report rather than attempt to view the file online.
  
  To assist users of the Summary Report in navigating the table more easily, when a submission letter link is clicked on, a new browser window will open. The Summary Report will remain open in the background. To return to it, simply close the letter window .


In order to standardize the chemical names of the HPV Challenge Program chemical lists, EPA is continuing to change the chemical names to reflect the Chemical Abstracts (CA) 9th Collective Index (9CI) names. Ninth Collective Index names are those used for the TSCA Inventory. Changes have been made to the following lists only: the HPV Challenge Program Chemical List, the 1994 List of HPV Additions, the Additional Chemicals Sponsored Under the HPV Challenge Program, and the Sponsored Chemicals List. Please note that chemical name changes are not highlighted on these lists. Chemical names on the HPV Challenge Summary Report have not been changed. Additional changes to chemical names will occur with future website updates as the Agency continues to review and modify its lists to reflect the appropriate chemical names.

• The Summary Report, chemical lists, sponsoring organizations and sponsored chemicals lists have been updated and is current as of August 29, 2003.
  
  Because the file is significant in size, we strongly encourage users to download the pdf version of the Report rather than attempt to view the file online.
  
  To assist users of the Summary Report in navigating the table more easily, when a submission letter link is clicked on, a new browser window will open. The Summary Report will remain open in the background. To return to it, simply close the letter window .


In order to standardize the chemical names of the HPV Challenge Program chemical lists, EPA is continuing to change the chemical names to reflect the Chemical Abstracts (CA) 9th Collective Index (9CI) names. Ninth Collective Index names are those used for the TSCA Inventory. Changes have been made to the following lists only: the HPV Challenge Program Chemical List, the 1994 List of HPV Additions, the Additional Chemicals Sponsored Under the HPV Challenge Program, and the Sponsored Chemicals List. Please note that chemical name changes are not highlighted on these lists. Chemical names on the HPV Challenge Summary Report have not been changed. Additional changes to chemical names will occur with future website updates as the Agency continues to review and modify its lists to reflect the appropriate chemical names.

Please note that dashes have been added to all CAS Numbers on this website. This change ensures that all CAS Numbers conform to standard CAS format. Dashes must now be included when searching for a CAS Number.
