Key value for chemical safety assessment
Acute toxicity: via oral route
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The available information comprises adequate, reliable (Klimisch score 2) studies from reference substances with similar structure and intrinsic properties. Read-across is justified based on common precursors and breakdown products of hydrolysis and consistent trends in environmental fate, ecotoxicological and toxicological profile (refer to the endpoint discussion for further details).
Taken together, the information from these independent sources is consistent and provides sufficient weight of evidence for hazard assessment leading to an endpoint conclusion in accordance with Annex XI, 1.2, of Regulation (EC) No 1907/2006. Therefore, the available information as a whole is sufficient to fulfil the standard information requirements set out in Annex VII, 8.5, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006.
Acute toxicity: via inhalation route
Endpoint conclusion
- Endpoint conclusion:
- no adverse effect observed
- Quality of whole database:
- The available information comprises an adequate, reliable (Klimisch score 2 due to read-across) study from a reference substance with similar structure and intrinsic properties. Read-across is justified based on common precursors and breakdown products of hydrolysis and consistent trends in environmental fate, ecotoxicological and toxicological profile (refer to the endpoint discussion for further details).
The selected study is thus sufficient to fulfil the standard information requirements set out in Annex VIII, 8.5, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006.
Acute toxicity: via dermal route

Additional information
Justification for read-across
Data on the acute oral, inhalation and dermal toxicity of Fatty acids, coco, decyl esters (CAS 93455-79-9) are not available. The assessment of acute toxicity was therefore based on studies conducted with analogue substances as part of a read across approach, which is in accordance with Regulation (EC) No. 1907/2006, Annex XI, 1.5. For each specific endpoint the source substance(s) structurally closest to the target substance is/are chosen for read-across, with due regard to the requirements of adequacy and reliability of the available data. Structural similarities and similarities in properties and/or activities of the source and target substance are the basis of read-across. A detailed justification for the analogue read-across approach is provided in the technical dossier (see IUCLID Section 13) and within Chapter 5.1 of the CSR.
Acute oral toxicity
CAS 95912-86-0
In a non-guideline study, 5 female mice were administered 5000 mg/kg bw fatty acids, C8-10, C12-18 alkyl esters (CAS 95912-86-0) via the oral route (Dufour, 1991). The study report contained limited information. No mortality occurred and no clinical signs were recorded during the 6-day observation period. There were no effects on body weight. The oral LD50 is considered to be > 5000 mg/kg bw.
CAS 20292-08-4
The acute oral toxicity of 2-ethylhexyl laurate (CAS 20292-08-4) was tested in 5 female Swiss mice comparable to OECD Guideline 401 (Bouffechoux, 1996). Administration of 2000 mg/kg b was single oral gavage dose caused no mortality, abnormal clinical reactions or changes in bodyweight gain. No effects were observed at gross pathology. Therefore, the acute oral LD50 in mice was found to be > 2000 mg/kg bw.
Acute inhalation toxicity
CAS 26399-02-0
The acute inhalation toxicity of 2-ethylhexyl oleate (CAS 26399-02-0) was assessed in a study performed according to OECD Guideline 436 (Van Huygevoort, 2010). 3 rats/sex were administered 5.7 ± 0.4 mg/L (actual concentration) of the test substance as an aerosol via nose-only exposure for 4 hours. The nominal concentration was 15.4 mg/L and the MMAD was 2.5-2.6 µm. No mortality occurred. The animals had a hunched posture on Day 2; no further clinical signs were observed during the 14-day observation period. The body weight gain was within the range that is normal for this strain and study type. No findings were reported during the macroscopic examination. The LC50 is considered to be > 5.7 mg/L.
Acute dermal toxicity
CAS 3687-46-5
An acute dermal toxicity study (limit test) was performed with decyl oleate (CAS 3687-46-5) according to OECD Guideline 402 (Beerens-Heijnen, 2010). 2000 mg/kg bw of the test substance was applied to the skin of 5 Wistar rats/sex under an occlusive dressing for 24 hours. No mortality occurred. Clinical signs were observed in all males on Day 1 and/or 2; as piloerection (2/5 males) or chromodacryorrhoea (3/5 males). No clinical signs were noted in females. The body weight increases were within the range expected for rats used in this type of study and no treatment-related findings were reported during the necropsy and histopathological examination. Erythema (grade 1) was observed on the treated skin for up to 4 days during Day 3-7 in 3/5 during the first week in 45 females. Scales or scabs (grade 1) were noted on the treated skin area in 5/5 females and 3/5 males for up to 9 days during Day 7-15 of the observation period. The LD50 is considered to be > 2000 mg/kg bw.
Overall conclusion for acute toxicity
The reliable data available for the read-across analogue substances indicate a very low level of acute toxicity following the oral, inhalation and dermal route, as LD50 and LC50 values were greater than the currently applied limit values. Therefore, as the available data did not identify any hazard for acute toxicity, Fatty acids, coco, decyl esters is not considered to be hazardous following acute exposure.
Justification for selection of acute toxicity – oral endpoint
Hazard assessment is conducted by means of read-across from structural analogues. All available studies are adequate and reliable based on the identified similarities in structure and intrinsic properties between the source and target substances and overall quality assessment (refer to the endpoint discussion for further details).
Justification for selection of acute toxicity – inhalation endpoint
Hazard assessment is conducted by means of read-across from a structural analogue. The selected study is most adequate and reliable based on the identified similarities in structure and intrinsic properties between the source and target substance and overall quality assessment (refer to the endpoint discussion for further details).
Justification for selection of acute toxicity – dermal endpoint
Hazard assessment is conducted by means of read-across from a structural analogue. The selected study is most adequate and reliable based on the identified similarities in structure and intrinsic properties between the source and target substance and overall quality assessment (refer to the endpoint discussion for further details).
Justification for classification or non-classification
According to Article 13 of Regulation (EC) No. 1907/2006 "General Requirements for Generation of Information on Intrinsic Properties of substances", information on intrinsic properties of substances may be generated by means other than tests e.g. from information from structurally related substances (grouping or read-across), provided that conditions set out in Annex XI are met. Annex XI, "General rules for adaptation of this standard testing regime set out in Annexes VII to X” states that “substances whose physicochemical, toxicological and ecotoxicological properties are likely to be similar or follow a regular pattern as a result of structural similarity may be considered as a group, or ‘category’ of substances. This avoids the need to test every substance for every endpoint". Since the analogue concept is applied to Fatty acids, coco, decyl esters (CAS 93455-79-9), data will be generated from data for reference source substance(s) to avoid unnecessary animal testing. Additionally, once the analogue read-across concept is applied, substances will be classified and labelled on this basis.
Therefore, based on the analogue read-across approach, the available data on acute toxicity do not meet the classification criteria according to Regulation (EC) 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
