EC number: 265-198-5
CAS number: 64742-94-5
A complex combination of hydrocarbons obtained from distillation of aromatic streams. It consists predominantly of aromatic hydrocarbons having carbon numbers predominantly in the range of C9 through C16 and boiling in the range of approximately 165°C to 290°C (330°F to 554°F).
Labelling for Low Benzene Naphthas
There are no ecotoxicological data available
for any of the streams in Category J.
The aquatic toxicity was estimated using the
PETROTOX computer model, which combines a partitioning model (used to
calculate the aqueous concentration of hydrocarbon components as a
function of substance loading) with the Target Lipid Model (used to
calculate acute and chronic toxicity of non-polar narcotic chemicals).
PETROTOX computes toxicity based on the summation of the aqueous phase
concentrations of hydrocarbon block(s) that represent a petroleum
substance and membrane water partition coefficients (KMW) that describe
the partitioning of the hydrocarbons between the water and organism.
The following short-term LL50s were
estimated using the PETROTOX model:
Short-term toxiticity to fish: LL50 value
for Onchorhynchus mykiss = 1.1 mg/L.
Short-term toxicity to invertebrates: LL50
value for Daphnia Magna = 1.99 mg/L.
Toxicity to algae: LL50 value for Pseudokirschneriella
subcapitata = 0.79 mg/l
Toxicity to microorganisms: LL50 value for
activated sludge = 28.99 mg/l
on the available predicted data (algal LL50 0.79 mg/L WAF) streams in
this category should have the classification Chronic 1 under the CLP
the classification of streams in this category may be impacted by other
which may impact the classification should be identified by the
registrants and the impact of their environmental classification
included in the assessment. The classification of each stream can be
determined following the equations given in the notes below.
the CLP Regulations
1 applies where: Acute 1 x M ≥ 25 %
1 applies where: Chronic 1 × M ≥ 25 %
2 applies where: (M × 10 × Chronic 1) + Chronic 2 ≥ 25 %
3 applies where: (M × 100 × Chronic 1) + (10 × Chronic 2) + Chronic 3 ≥
4 applies where: Chronic 1 + Chronic 2 + Chronic 3 + Chronic 4 ≥ 25 %
