Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Workers - Hazard for the eyes

Additional information - workers

Chronic and sub-chronic toxicity studies have shown that long chain alcohols (LCA) are of low toxicity. Furthermore, combined repeated-dose studies with developmental endpoints, as well as reproductive and developmental studies showed no effects at the highest dose tested.

 

Rather than having separate values for the three endpoints, one endpoint systemic effects has been used instead. Since the NOAELs do not vary greatly across the category, one key study has been chosen as being representative of the whole category.

 

C6, Hexanol has been chosen as the category representative because shorter chain molecules are usually regarded as more toxic when compared to structural analogues with longer carbon chain lengths. The 13-week repeat dose study on 1-hexanol by (Sc. Assoc. 1966) has been used as the key study for deriving the Indicative Human No Effect Level (IHNEL) for LCA category. This study reported a NOAEL of 1127 mg/kg (bw).

 

In addition the C9-C14 aliphatics (2-25% aromatics) presented neither systemic nor local effects when observed in a repeated dose toxicity study by inhalation. An inhalation DNEL for aerosol was set at 10 mg/m3, recommended by REACH (Chapter R8.7.1), and based on the assumption that as aerosol, these substances could be considered as non-soluble dust.
