EC number: 271-237-7
CAS number: 68526-89-6
A complex combination of hydrocarbons produced by the distillation of products from the hydrogenation of isononanal from the hydroformylation of octene. It consists predominantly of C9-10 primary aliphatic alcohols, C10-20 dimer alcohols, C>18 acetals and esters and C>18 acid sodium salts and boils in the range of approximately 200°C to 400°C (392°F to 752°F).
In a GLP study according to the OECD guideline 208 the acute
toxicity of the test mixture on three plant species (Avena sativa,
Brassica napus, Glycine max) was tested. The test species were exposed
to the test mixture in artificial soil and over a test period of 21
days. Based on seedling emergence an EC50 (21 d) > 1000 mg/kg soil dw
and a NOEC (21 d) = 1000 mg/kg soil dw for all three test species were
found. Based on shoot height the most sensitive test species were Avena
sativa and Brassica napus. For both plant species an EC50 (21 d) > 1000
mg/kg soil dw and NOEC (21 d) values of 500 mg/kg soil dw were measured.
Based on shoot fresh weight the most sensitive plant species was
Brassica napus. For this species a NOEC (21 d) of 125 mg/kg soil dw and
an EC25 (21 d) of 356 mg/kg soil dw were determined. The EC50 was found
to be > 1000 mg/kg soil dw [Evonik Oxeno 2009].
