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 some cases the CAS and chemical identity stated refer to SDA nomenclature for this substance. In REACH substance identification it is necessary to be more specific as to the chain lengths present. Full details may be

found in the CSR.
