…Updated guidance on (quantitative) structure-activity relationships

ECHA has updated its practical guide on the use and reporting of (Q)SARs, providing further advice on using these in REACH registrations. Practical examples cover the prediction of Log Kow, ready biodegradability, short-term toxicity to fish and acute toxicity to rats.

…Consultations on four potential substances of very high concern (SVHCs)

Member State competent authorities and the European Chemicals Agency may prepare Annex XV dossiers for the identification of SVHCs which are carcinogenic, mutagenic or reprotoxic (CMR), persistent, bioaccumulative and toxic (PBT), very persistent and very bioaccumulative (vPvB), or of an equivalent level of concern (ELoC). The latest dossiers have been released by the German and Swedish authorities, and cover:

  • benzo(a)pyrene (CMR (as it is carcinogenic, mutagenic and toxic to reproduction), PBT and vPvB)
  • 3-benzylidene camphor (ELoC (endocrine disruption))
  • dicyclohexyl phthalate (DCHP) (CMR (toxic to reproduction), ELoC (endocrine disruption))
  • 4-methylbenzylidene camphor (ELoC (endocrine disruption))

…Restriction proposal on octamethylcyclotetrasiloxane (D4) and decamethylcyclopentasiloxane (D5)

ECHA’s Committee for Risk Assessment (RAC) supports a proposal to restrict the placing on the market of D4 and D5 in personal care products intended to be used or disposed with water (e.g. shower gels, shaving foams and shampoos). The chemicals have a potential to accumulate in the environment, with long-term effects that are difficult to predict or reverse. European Chemicals Agency (2016).

…Other items of interest

An amendment (Regulation (EU) 2016/266) to Regulation (EC) No 440/2008, which lays down test methods pursuant to REACH, includes methods for determining partition coefficients, ecotoxicity and environmental fate.
