In summary of the toxicological properties of (Z)-octadec-9-enol and
Acute toxicity tests of (Z)-octadec-9-enol do not indicate any potential
hazard for acute, dermal or inhalation
toxicity, and would not be classified for acute toxicity endpoint under
Regulation 1272/2008 (CLP).
(Z)-octadec-9-enol is not irritating to skin or eye, nor is it
sensitising by skin contact.
(Z)-octadec-9-enol is not classified for repeated dose toxicity effects
(STOT-RE) or for reproductive toxicity.
In vitro and in vivo studies indicate that (Z)-octadec-9-enol is not
In summary, (Z)-octadec-9-enol is not classified for human health hazard
under Regulation 1272/2008 (CLP).
On the basis of the toxicological results available no adverse systemic
effects were observed in any of the
numerous systemic toxicity studies that have been conducted for the
different endpoints. Nevertheless, systemic
DNEL values have been derived for systemic effects based on the highest
dose tested. The DNELs are therefore indicative only and is derived as a
The German regulatory authority imposes a statutory national workplace
limit concentration of several analogous
alcohols in air in industrial workplaces (AGW), though no value is set
itself. The value derived for (Z)-octadec-9-enol is equivalent to 219.5
Overall it would however be prudent to highlight the necessity to ensure
good general hygiene measures are adhered
to in the workplace, and to recommend the precautionary use of gloves.
