All the category substances are fatty acid esters. After oral ingestion, it is expected that substances are hydrolyzed by pancreatic lipases. The degradation products are free fatty acids and free alcohol which could be distributed in organism through systemic circulation. They are expected to be metabolized in common energetic pathways or excreted and not bioaccumulable after repeated administration.
Three relevant studies are available for assessment. None of these studies, performed according to OECD TG 407 and 408 methods, showed adverse effect to rats during the entire treatment period.
These experimental studies are consistent with the low toxicity expected for these substances.
Applicant's summary and conclusion
- Conclusions:
- Based on the category approach and on the available experimental results, the NOAEL value applied for the category is higher than 800 mg/kg bw. Hence, the category substances did not required classification for STOT-RE in absence of adverse effects.
- Executive summary:
According to the Regulation (EC) NO. 1907/2006, Annex XI, 1.5, A read-across category for short chain fatty acid was performed in order to provide informations on ethyl decanoate CAS 110-38-3.
This category was based on common and shared physico-chemical and structural properties as:
- common functional group,
- common precursors and the likehood of common impurities as well as common breakdown products via biological processes, which are chemically structurally similar, and
- constant pattern in the changing of the potency of the properties across the category.
The category substances are fatty acid esters covering chain length C8 to C18 satured or unsatured linked to alcohol including ethanol, isopropanol, octanol, hexanol and 2-ethylhexanol. These substances showed similar physico-chemical properties as very low solubility in water, not volatile, ready biodegradable and high log Kow. The substances are expected to have same toxicity behavior according to the common structural and physico-chemical similarities. Indeed, they are expected to be metabolized or excreted in same way when orally administered in organism.
Based on the category approach and on the available experimental results, the NOAEL value applied for the category is higher than 800 mg/kg bw. Hence, the category substances did not required classification for STOT-RE in absence of adverse effects according to CLP criteria.
