DINP REACH Consortium

The leading European manufacturers of DINP have joined efforts for their REACH compliance activities and have launched the DINP REACH consortium.

Through the DINP REACH consortium, the manufacturers have decided to join efforts to prepare a consistent registration dossier building on the experience gained during the previous European existing chemicals risk assessment program.  The project management and secretariat of the consortium will be handled by ReachCentrum.

Substances covered

The commercial product DINP has to be registered under the REACH legislation and covers two EINECS/CAS numbers as detailed below:

Substance name EC Number CAS Number Proposed Registration Status

Di-isononyl phthalate 



Full registration >1,000 t/y 

1,2-benzenedicarboxylic acid, 
di-C8-10-branched alkyl esters, 



Full registration >1,000 t/y 



The DINP REACH consortium structure includes Steering and Technical Committees and the consortium secretariat managed by ReachCentrum. The consortium is open to any applicant fulfilling the membership criteria - manufacturers, importers, only representatives as defined in the REACH Regulation of the substance on its own, in preparations or in articles and that are subject to the registration requirements pursuant to the REACH Regulation, or Affiliates thereof.

The DINP REACH consortium has adopted the Cefic proposal for the coding of SIEFs and will commence communicating with SIEF pre-registrants shortly.
