Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The criteria set out under REACH for determining whether a substance is PBT/vPvB are as follows:
Criterion
PBT criteria
vPvB criteria
P
Half-life (T½) > 60 d in marine water or
Half-life (T½) > 40 d in fresh or estuarine water or
Half-life (T½) > 180 d in marine sediment or Half-life (T½) > 120 d in fresh or estuarine water; sediment or
Half-life (T½) in soil > 120 d
Half-life (T½) > 60 d in marine fresh or estuarine water or
Half-life (T½) > 180 d in marine, fresh or estuarine water; sediment
Half-life (T½) > 180 d in soil
B
BCF > 2000 L/kg in fresh or marine aquatic species
BCF > 5000 L/kg
T
Chronic NOEC < 0.01 mg/l for marine or freshwater organisms, or
Substance is classified as carcinogenic (category 1 or 2), mutagenic (category 1 or 2), or toxic for reproduction (category 1, 2 or 3) or
There is other evidence of chronic toxicity, as identified by the classifications: T, R48, or Xn, R48 according to Directive 67/548/EEC.
Not applicable
Note: (a) BCF is bioconcentration factor, NOEC is no-observed effect concentration and CMR is a substance classified as carcinogenic, mutagenic or toxic for reproduction
(b) For marine environmental risk assessment, half-life data in freshwater sediment can be overruled by data obtained under marine conditions
(c) Substances are classified when they fulfil the criteria for all three inherent properties for P, B and T. However, there is certain flexibility, for instance in cases where one criterion is marginally not fulfilled but the others are exceeded considerably.
The above are the definitive criteria for PBT assessment and listed in Annex XIII of REACH; however, an initial screening step was carried out to identify potential candidates for more detailed PBT assessment. Constituents of the stream were evaluated for potential to be persistent, bioaccumulative or toxic using QSARs associated with EPIsuite v4. The results of these evaluations are found in the table below

Notes
1) For the purpose of running EPIsuite, single substances have been selected to represent unsaturated C8 hydrocarbon
2) Log Kow has been estimated using KOWWIN v1.67
3) BCF has been estimated using BCFBAF v3.0
4) Ready biodegradability has been predicted using BIOWIN v4.10
5) Acute aquatic toxicity is lowest value selected from results estimated for toxicity to fish, invertebrates and green algae using ECOSAR v1.0 (class neutral organics)
Conclusion
Screening data of the various constituents indicates that Reaction Products of C4 alcohols and C4 alkenes obtained as by-products from the manufacturing of butan-2-ol by sulfuric acid esterification and hydrolysis of butene has the potential to be persistent, but not bioaccumulative or toxic.
