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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 951-918-1 | CAS number: -
Bioaccumulation: aquatic / sediment
Administrative data
- Endpoint:
- bioaccumulation in aquatic species: fish
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study

Materials and methods
- Principles of method if other than guideline:
- This model uses a linear relationship between log Kow and BCF to predict the BCF of a test substance. This linear relationship applies to substances with a log Kow <6. The linear model has b een validated using a dataset other than the training dataset. For substance with a log Kow >6, the polynomial method has been used.
- GLP compliance:
- not specified
Test material

- Not applicable to UVCB substance
- IUPAC Name:
- Naphtha (petroleum), catalytic reformed, co-processed with hydrocarbons derived from thermally cracked waste plastics
- Test material form:
- liquid
- Details on test material:
- - Name of test material (as cited in study report): REF REFT Talvi
