Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Acute Toxicity – Oral LD50 >5000 mg/kg for rat (OECD TG 420).

Key value for chemical safety assessment

Additional information

The Heavy Oxo Fraction (Alkenes, C6-10, hydroformylation products, high-boiling, CAS#68526-82-9) is a mixture of components: A complex mixture of oxygenated hydrocarbons, primarily alcohols (C8 to C11) and aliphatic ethers (C16 to C22). All structures are branched and multi-isomeric. For the purposes of read across, data will be used from a commercial substance (Vammar D10, CAS #98072-31-2) that contains similar aliphatic ethers to Mixed HOF.

 

Acute exposure to CAS # 98072 -31 -2 has a low potential for toxicity via the oral route.  The LD50 via the oral route is greater than 5,000 mg/kg.

Justification for classification or non-classification

No classification for acute toxicity is indicated according to the general classification and labeling requirements for dangerous substances and preparations (Directive 67-548-EEC) or the classification, labeling and packaging (CLP) regulation (EC) No 1272/2008.
