The weight of evidence from the available toxicological information on higher olefins shows that the members of this category have a low hazard potential with regard to human health, with dermal irritation the only effect recorded for some materials. As there are no quantifiable toxicological effects for these substances, DNELs have not been derived.
Acute toxicity
The higher olefins included in this category were not acutely toxic when administered via oral, dermal, or inhalation routes in several animal studies. Hence, these substances do not meet the classification and labelling criteria for acute oral, dermal, or inhalation toxicity according to CLP Regulation 1272/2008. Therefore short-term DNELs will not be derived for these endpoints. In contrast, regulatory classification and labelling for aspiration toxicity relies on the measured or calculated kinematic viscosity of a substance at 40°C rather than results from toxicological studies with animals, with substances where the kinematic viscosity is less than 20.5 mm2/second requiring classified (Category 1 - H304: May be fatal if swallowed and enters airway). All higher olefins included in this category which exist as liquids at 40°C are therefore classified as aspiration hazards because their respective kinematic viscosities are below the discriminating threshold established in the CLP Regulation.

The results from these tests showed no adverse substance-related effects after treatment via oral or inhalation exposure. Hence, these substances do not meet the classification and labelling criteria for repeated toxicity or toxicity to reproduction according to CLP Regulation 1272/2008. Therefore long-term DNELs will not be derived for these endpoints.
