Alchisor CAL 145 comprises alkenes C13-14 hydroformylation products and read-across from the chemically-similar Alchisor CAL 123 has been used in this hazard assessment as defined in the `Read-Across Justification Document'. Where environmental toxicity data exist for Alchisor CAL 123, these are representative of the Alchisor CAL 145 substance. In accordance with REACH Annex IX, the requirement for toxicity sediment organisms is waived on the basis of lack of direct or indirect exposure to sediment organisms, ready biodegradability in water and low toxicity to aquatic life. No reliable predicted or measured toxicity data to sediment organisms are available for Alchisor CAL 145 (or Alchisor CAL 123).

accordance with REACH Annex X, the requirement for studies of the
effects on sediment organisms is waived on the basis of unlikely direct
and indirect exposure of the sediment compartment. In
addition, other evidence presented in this dossier on the substance's
ready biodegradability and low toxicity to aquatic organisms further
support the waiver. No reliable predicted or measured toxicity to
sediment organisms data are available for Alchisor CAL 145 (or Alchisor
is unlikely that sediment organisms will be exposed to Alchisor CAL 145
as there is no intended use involving the direct application of Alchisor
CAL 145 to watercourses and their sediments. In
addition, it is unlikely that indirect exposure will occur, via the
water column, as Alchisor CAL 145 is deemed readily biodegradable.
chemically-similar Alchisor CAL 123 has been shown in the reliable
(Klimisch 1; Klimisch 2 when used for read-across) study by Schaefer and
Matthews (2010) to be readily biodegradable in water. The test substance
biodegraded to an extent of 87.7% after 28 days and although the
biodegradation rate just missed the 10-day window threshold, this aspect
of the test is not applicable to mixtures where different components of
the mixture can biodegrade preferentially (reference TG 103C). It
is assumed that Alchisor CAL 145 will readily biodegrade in water and be
unavailable for long-term uptake by fish.
to Aquatic Organisms
toxicity of the chemically-similar Alchisor CAL 123 to aquatic organisms
is very low based on the evidence presented in this dossier. The
lowest measured toxicity was based on an algal test where the NOEL based
on algal growth was 25 mg/L. Acute toxicity to invertebrates and fish
was >100 mg/L based on 50% mortality. In
addition, because the substance has been deemed readily biodegradable,
it is unlikely that aquatic organisms would encounter long-term exposure
to the substance. Using
this evidence it is assumed that Alchisor CAL 145 represents a low
hazard and is not considered to be toxic (in PBT terms) to aquatic and
