EC number: 271-078-3
CAS number: 68515-37-7
A complex combination of hydrocarbons produced by the esterification of phthalic anhydride with isononyl alcohol. It consists predominantly of C9 primary alcohols, C9 paraffins, and saturated and unsaturated C18 ethers and boiling in the range of approximately 120°C to 220°C (248°F to 428°F).
Discard alcohol is a mixture of components: a mixture of C8-13 branched
hydrocarbons, C9-13 branched primary alcohols and C10-12 cyclic ethers.
All components are multi-isomeric. The composition is variable. All
structures are branched and multi-isomeric. For the purposes of read
across, an equivalent alcohol will be used, as will data from a
commercial substance (Vammar D10, CAS RN 98072-31-2) that contains
similar aliphatic ethers to Discard alcohol.
Data is available for short-term toxicity to fish, and short-term
toxicity to aquatic invertebrates to meet REACH requirements.
The acute toxicity of Alcohols, C9-11-iso, C10-rich, as measured by
mortality to rainbow trout (Oncorhynchus mykiss) was evaluated in
freshwater. Based on the nominal loading of the test substance in water,
the 96 -hr LL50 value was 3.0 mg/l.
The Vammar D10 rainbow trout (Oncorhynchus mykiss) LL50 value was
greater than 100 mg/L.
The acute toxicity of Alcohols, C9 -11 -iso, C10 -rich, as measured by
immobility to the water flea (Daphnia magna) was evaluated in
freshwater. The 48-h EL50 for Daphnia magna was 6.2 mg/l, based on
nominal loading of the test substance in water.
The 21 -d Daphnia magna NOELR (reproduction) was >9.7 mg Vammar D10/L.
