Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information

Additional information

Kerosine fractions are not readily biodegradable but are considered inherently biodegradable. In a report on environmental classification (Concawe 2001), it was concluded that, based on the known properties of hydrocarbons in the range C9 to C16,kerosines are not readily biodegradable, but are regarded as being inherently biodegradable, since they can be degraded by micro-organisms.

In a further investigation (Concawe 2012) on PBT evaluation of petroleum substances CONCAWE developed QSAR estimates (BioHCwin) and reviewed existing data for individual hydrocarbons representative of the various ‘hydrocarbon blocks’ covering a range of petroleum substances. Using the Hydrocarbon Block method and data on biodegradation of representative hydrocarbons in the range C9 to C20, it is concluded that kerosines do not meet the persistence criteria and can be regarded as being inherently biodegradable.

Biodegradation in water screening test:

Substance is a hydrocarbon UVCB. Tests for biodegradation in water are designed for use with single chemical substances and results used for classification.

Kerosine fractions are not readily biodegradable but are considered inherently biodegradable.

Biodegradation in water and sediment, simulation test:

Substance is a hydrocarbon UVCB. Tests for biodegradation in water are designed for use with single chemical substances and results used for classification. For the purpose of risk assessment, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks. The environmental risk of this substance is assessed using the PETRORISK model (see PETRORISK report attached to IUCLID Section 13).

Biodegradation in soil:

Substance is a hydrocarbon UVCB. Standard tests for this endpoint are intended for single substances and are not appropriate for this complex substance. However, this endpoint is characterized using quantitative structure property relationships for representative hydrocarbon structures that comprise the hydrocarbon blocks used to assess the environmental risk of this substance with the PETRORISK model (see PETRORISK report attached in IUCLID section 13).
