New CLH public consultation launched on hydroxyisohexyl 3-cyclohexene carboxaldehyde and bupirimate


ECHA invites the parties concerned to comment on two proposals for harmonised classification and labelling (CLH) of hydroxyisohexyl 3-cyclohexene carboxaldehyde and the pesticide bupirimate. The public consultation will be open for 45 days and will end on 16 August 2013.

Helsinki, 2 July 2013 – Hydroxyisohexyl 3-cyclohexene carboxaldehyde is a multi-constituent substance which is widely used in the manufacture of various consumer products, such as cleaning products and detergents, cosmetics, scented products and room fresheners. The submitting Member State, Sweden, proposes classification for skin sensitisation.

Bupirimate is a pesticide approved under Regulation (EC) No 1107/2009 concerning the placing of plant protection products on the market. The CLH dossier, submitted by the Netherlands, proposes classification for carcinogenicity, skin sensitisation and hazardous to the aquatic environment.

Neither of the substances have harmonised entries in Part 3 of Annex VI to the CLP Regulation.

The CLH reports and the dedicated webform to post the comments are available on the ECHA website. The comments received during the public consultation will be regularly published on the ECHA website during the 45-day consultation phase.
