Adopted opinions and previous consultations on applications for authorisation

 

This page provides further information on the applications for authorisation or review reports, which have undergone public consultation. The applications for authorisation are in the opinion development phase until the final opinions of the Committees for Risk Assessment and Socio-economic Analysis have been adopted and sent to the European Commission. The European Commission's decision-making process can be followed through the comitology register, where further information is published about the REACH Committee's past and upcoming meetings.

Substance Details

Name
Pentazinc chromate octahydroxide
EC Number
256-418-0
CAS Number
49663-84-5
Entry Nr in Annex XIV

Use name
Formulation of mixtures
Broad information on use applied for (conditions of use and function)
Pentazinc chromate octahydroxide is an ingredient in the Rockhard Primer paint formulation which is manufactured in a few batches (about 8 batches per year, 0.8 tonnes per batch) over any year. The concentration of pentazinc chromate octahydroxide in the formulation is less than 1%.

The formulation of coatings is a multi-stage batch process. The process involves the following steps: storage, decanting, weighing, transfer to mixing vessel, mixing by dispersion and wet-grinding, transfer to small containers, maintenance and cleaning of equipment, waste management and laboratory activities. These steps are not fully contained, therefore they can be considered as open processes.

The substance has no independent function at the formulation stage. The process is arranged to maximise the efficiency of use of input raw materials, through the highest conversion into formulated products.

Annual tonnage used: 0.06 tonnes of pentazinc chromate hydroxide (equivalent to approx. 0.006 tonnes Cr(VI))
Number of sites: 1
Review period requested: 12 years
