RAC agrees on two opinions on occupational exposure and on 11 harmonised classification cases

ECHA/NA/17/15

The Committee for Risk Assessment (RAC) has for the first time adopted scientific opinions on occupational exposure for two substances: MOCA and for arsenic acid and its inorganic compounds. RAC adopted 10 opinions on harmonised classification and labelling and additionally agreed on the classification of titanium dioxide. The committee also agreed on 14 draft opinions and adopted one final opinion on applications for authorisation.

Helsinki, 14 June 2017 – At the request of ECHA’s Executive Director, RAC drew up an opinion on the evaluation of the scientific relevance of the occupational exposure for MOCA and for arsenic acid and its inorganic salts. More details on the adopted opinions are available at the link below.

RAC continued its discussion on titanium dioxide, which had started in March this year. The committee concluded that the available scientific evidence meets the criteria in the CLP Regulation to classify titanium dioxide as a substance suspected of causing cancer through the inhalation route (Carc. 2; H351 (inhalation)). The opinion will be formally adopted later by written procedure or at the September meeting.

The committee also adopted 10 opinions on harmonised classification and labelling proposals.

RAC continued their work on 12 applications for authorisation. The committee agreed on 14 draft opinions on specific uses of chromium (VI) substances, 1,2-dichloroethane (EDC), bis(2-methoxyethyl) ether (diglyme) and 2,2’-dichloro-4,4’-methylenedianiline (MOCA). The draft opinions will be sent to the applicants for comments before final adoption.

The committee also finalised its work on one further application for authorisation by adopting the opinion on the use of diglyme as a process solvent in the manufacturing of an intermediate for an active pharmaceutical ingredient (API).

More details on the final opinions related to applications for authorisation and on the adopted opinions on harmonised classification and labelling proposals are available in the annex below.
