Last update : October 2011 Additional information on REACH registration dossier

Additional information on REACH registration dossier
The additional information compiled in this document is included in the REACH registration dossier for 4,4'-isopropylidenediphenol but is currently not disseminated on the ECHA website. However, the registrants believe that this information is required to comprehend the conclusions as derived in the REACH registration dossier for 4,4'-isopropylidenediphenol.
Please note that at present two registration dossiers for 4,4'-isopropylidenediphenol are available on the ECHA website. This is due to the fact that one registrant chose to submit an individual registration dossier despite being aware that a joint registration dossier had already been submitted by the Bisphenol A REACH consortium. The extensive registration dossier of the Bisphenol A REACH consortium can easily be identified by the IUPAC name 2,2-bis(4-hydroxyphenyl)propane in section 1.1 of the disseminated registration dossier. The additional information does only refer to this registration dossier as submitted by the Bisphenol A REACH consortium.

Status of Dossier Preparation - August 2010
The Registration Dossier for Bisphenol A has been submitted by the Lead Registrant Bayer MaterialScience AG and has been accepted by ECHA.
Based on the costs of the studies included in the IUCLID file and taking into account the work that has been done to generate IUCLID and Chemical Safety Report, the BPA REACH Consortium has assessed the value of the Registration Dossier.
In a poll that was conducted until 23rd of July 2010 all SIEF members were notified of the price estimate for a Letter of Access to the Registration Dossier and were asked if they intend to submit a registration in 2010.
Based on the number of registrants the price for the Letter of Access was determined and registrants were invited to purchase the Letter of Access via ReachCentrum´s LoA Module. If you have not participated in the poll but do nevertheless intend to submit a registration for Bisphenol A we kindly request that you contact the Consortium Manager.

Communication in pre-SIEF and SIEF
On 23rd April 2009, the SIEF Formation Facilitator invited all pre-registrants of Bisphenol A to complete the SIEFreach survey for Bisphenol A. On 19 May 2009, all pre-registrants of Bisphenol A received a summary of the survey results which indicated their selected SIEF status. Meanwhile, some pre-registrants contacted the SIEF Formation Facilitator  to have their level of SIEF involvement changed. Their SIEF status was modified accordingly.

This SIEF status will now be used to manage communication within the pre-SIEF and SIEF. If you have been labelled as dormant in the summary from 19th May 2009 and did not request a modification of this status, you will not be included in any further communication on Bisphenol A.

Please note that your SIEF status can be changed at any time by contacting the SIEF Formation Facilitator or the Bisphenol A consortium secretariat.

Formation of SIEF and Election of Lead Registrant
On 9th June 2009 an invitation to a poll was sent by ReachCentrum to all non-dormant pre-registrants. This poll aimed to facilitate agreement on substance identity and to obtain approval on the Lead Registrant. The results of the poll were distributed to all non-dormant pre-registrants on 26th June 2009.

All participants in the poll accepted the following sameness definition:

Bisphenol A, EINECS 201-245-8, CAS 80-05-7 is a mono-constituent substance with a content of = 80% (w/w) 4,4'-isopropylidenediphenol that does not contain any impurities at concentration levels that would require a change in existing EU classification for Bisphenol A and that does not contain any impurities at concentration levels that would require a PBT/vPvB assessment of the substance.

All participants in the poll approved of Bayer MaterialScience AG as Lead Registrant for Bisphenol A.

In accordance with the results of the poll, the SIEF for Bisphenol A has been formed and Bayer MaterialScience AG was unanimously elected as Lead Registrant.

If you are a non-dormant pre-registrant but did not indicate agreement with the proposed sameness definition for any of your UUIDs, these UUIDs will not be members of the SIEF for Bisphenol A. In this case it will be assumed that these UUIDs have no intention to cooperate in the SIEF and in order to avoid any unnecessary e-mail traffic, these UUIDs will not be included in any further SIEF communication. However, any UUIDs that are currently not members of the SIEF but intend to join the SIEF are welcome to contact the Lead Registrant or the Bisphenol A consortium secretariat indicating that they agree with the above sameness definition. Those UUIDs will then become members of the SIEF for 4,4'-isopropylidenediphenol and will be included in further SIEF communication.
