Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Key value for chemical safety assessment
Skin sensitisation
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed (not sensitising)
- Additional information:
There is no data available measured on the test substance itself " Pentadecane, 7-methylene mixed with 1-tetradecene, dimers and trimers, hydrogenated", which is a C28 -80H58 -162 saturated branched alphaolefin oligomer of number average molecular weight 443 (Mw=448) but data is available on three analogue alphaolefins that are oligomerised and hydrogenated 1-decene. These span a number average molecular weight of 287 -528 and whilst linear rather than branched are likely to behave similarly for these end points.
SKIN SENSITISATION
The table below indicates the results from the analogue substances:
Analogue Mn Classification 287 No hypersensitivity 443 No hypersensitivity 528 No hypersensitivity There is no indication of hypersensitivity within this class of substances across a molecular weight range which spans that of interest for the substance of interest. In can be concluded that the substance " Pentadecane, 7-methylene mixed with 1-tetradecene, dimers and trimers, hydrogenated" has low skin sensitisation potential. From a quantitative perspective, the study used 0.5ml over an 8cm2 patch, which is equivalent to 50mg/cm2
Migrated from Short description of key information:
There is no data on the substance of interest but data exists on three analogue 'read across' substances. See discussion section.
Justification for classification or non-classification
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
