There are no data regarding the substance's sub-chronic toxicological effects and the data regarding long term exposure is limited to a single OECD 422 study. Systemic effects with regards to the repeated dose exposure to the substance were seen in this study and as the oral NOAEL is considered suitable to be used in extrapolating both the dermal and inhalation DNELs for this material the results of this study have been used as the starting point of the derivations. An additional safety factor of 2 has been applied in order to account for the limited information on chronic reproductive and chronic toxicity and that only one species has been examined. The value of 2 rather than a higher figure reflects the non-specific nature of the toxicity observed. Similarly data on reproductive toxicology is limited to the same OECD 422 study, although effects were considered to be limited to maternal toxicity and related to lower bodyweight gains in the top dose group. No effects specifically related to reproductive health of the animals were seen.
The substance is considered not to be harmful following acute administration by the oral route and furthermore read across to data on the two structural fragments (Tall oil and ethanolamine) suggests that the substance would not be harmful by dermal exposure either. The substance has a high log Pow and low water solubility and is therefore considered unlikely to fully penetrate the epidermis making dermal absorption unlikely. The substance exists in the form of a highly viscous gel or paste and has a low vapour pressure which suggests that inhalation exposure is unlikely.
No irritant or sensitising effects were seen in the applicable studies on analogous substances that have used to support the registration of this substance and it is concluded that the same would be true for the substance itself. The limited data available on the substance itself support this conclusion. No local effects are expected following exposure to the substance. Hence, derivation of DNELs for local effects (Either short or long term) is not considered necessary.
Based on the available studies used to support the registration, the substance would not be considered to exhibit any genotoxic potential.

Additional information - General Population
Exposure to the general population is not expected based on the substance use pattern. Tall oil, compounds with ethanolamine is intended for use within industrial and professional use sectors only and no uses by the general population are anticipated. As such it is considered justified not to derive a DNEL for this type of exposure.
