Test Guidance
OECD guideline 404 and EC Method B.4 (Acute Toxicity: Dermal Irritation / Corrosion).
Method and materials
Three New Zealand White male rabbits were dermally exposed to 0.5 mL of the test material for 4 h under a semi-occlusive dressing. After removal of the residual test item, irritation was scored immediately following removal of the patches and approximately 1, 24, 48 and 72 h later, according to Draize method.
Results
Very slight erythema was noted at two treated skin sites 1 and 24 h after patch removal. No evidence of skin irritation was noted at one treated skin site during the study. All animals showed expected gain in body weight during the study. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0, 0.3, 0.3 for erythema and 0.0, 0.0, 0.0 for oedema score, respectively. The mean erythema and oedema scores at 24, 48 and 72 h were 0.22 and 0.0 respectively. The substance is not a skin irritant in male rabbits.
Conclusion
Under the test conditions the substance is not classified as irritating to skin according to CLP Regulation (EC) No. 1272/2008.

Test Guidance
OECD guideline 405 and EC Method B.5 (Acute Toxicity: Eye Irritation / Corrosion).
Method and materials
Three New Zealand White male rabbits were exposed to 0.1 mL of test item in the right eye while the left eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined and the changes were observed at 1, 24, 48 and 72 h after treatment and graded according to the Draize method.
Results
No corneal or iridial effects were noted during the study. Moderate conjunctival irritation was noted in all treated eyes one hour after treatment with minimal conjunctival irritation noted at the 24 h observation. All treated eyes appeared normal at the 48 h observation. One animal showed body weight loss, one animal showed no gain in body weight and the remaining animal showed expected gain in body weight during the study. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0, 0.0, 0.0 for cornea score; 0.0, 0.0, 0.0 for iris score; 0.3, 0.3, 0.3 for conjunctivae score and 0.3, 0.3, 0.3 for chemosis score. In this study, the test substance is not an eye irritant in male rabbits.
Conclusion
Under the test conditions, the substance is not classified as irritating to eyes according to CLP Regulation (EC) No. 1272/2008.

Additional information
Data for skin and eye irritation are available from studies performed using the substance itself. In addition, read-across data are available and these data are used to support the studies on the substance itself.
Read-across to the toxicological properties of fatty acid polyols (Fatty acids, C5-9, esters with pentaerythritol (EC 270-290-3, CAS 68424-30-6) and Decanoic acid, ester with 2-ethyl-2-(hydroxymethyl)-1,3-propanediol octanoate (EC 234-392-1, CAS 11138-60-6)) and their analogues is applicable based on the similarity in structure and physico-chemical properties. The substance with the CAS No. 131459-39-7 is a structural analogue of one of the read-across substances (CAS No. 68424-30-6) and can therefore be used for read-across. The justification for read-across is presented in Section 13 Assessment reports- Read-across justification.
Skin Irritation
One reliable study is available. In this study (Sanders, 2013) performed under GLP according to OECD TG 404 and EC Method B.4, three male New Zealand White rabbits were exposed to 0.5 mL of the substance for 4 hours under semi-occlusive conditions. After removal of the residual test item, irritation was scored immediately following removal of the patches and approximately 1, 24, 48 and 72 h later, according to Draize method. Very slight erythema was noted at two treated skin sites 1 and 24 h after patch removal. No evidence of skin irritation was noted at one treated skin site during the study. All animals showed expected gain in body weight during the study. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0, 0.3, 0.3 for erythema and 0.0, 0.0, 0.0 for oedema score, respectively. The mean erythema and oedema scores at 24, 48 and 72 h were 0.22 and 0.0 respectively. The substance is not a skin irritant in male rabbits.
In a supporting study, 2,2-bis[(octanoyloxy)methyl]butyl decanoate (CAS No. 11138-60-6) was tested for its skin irritation potential according to OECD Guideline 404 (Clouzeau, 1990): The shaved back of three New Zealand White rabbits was exposed to 0.5 mL test material for 4 hours under semi-occlusive conditions. The rabbits were observed for 3 d after exposure and skin reactions were assessed using the Draize scheme periodically (24, 48 and 72 hours) after removal of the test substance. No cutaneous reactions were observed in any of the tested animals at any observation interval.
Furthermore, the result of an acute dermal toxicity study on CAS 131459-39-7 which was conducted according to OECD 402 (Allen, 1999) can be used for risk evaluation of the irritation potential and supports the view that a non-classification of fatty acid polyol esters with short chain length of the fatty acids is warranted for skin irritation. This fatty acid polyol is composed of C5 -C9 fatty acids with pentaerythritol. A single dose of 2000 mg/kg bw of the test material was applied on the shaved skin of five Sprague-Dawley rats for 24 h under semiocclusive conditions and, in addition to mortality and systemic effects, the skin reactions were observed for up to 14 days after exposure. None of the animals showed any signs of skin reaction (erythema/edema/scale) after exposure to this limit dose.
Eye Irritation
One reliable study is available. In this study (Sanders, 2013) performed under GLP according to OCED TG 405 and EC Method B.5, three male New Zealand White rabbits were exposed to 0.1 mL of the substance in the right eye while the left eye remained untreated and served as control. The eyes were examined and the changes were observed at 1, 24, 48 and 72 h after treatment and graded according to the Draize method. No corneal or iridial effects were noted during the study. Moderate conjunctival irritation was noted in all treated eyes one hour after treatment with minimal conjunctival irritation noted at the 24 h observation. All treated eyes appeared normal at the 48 h observation. One animal showed body weight loss, one animal showed no gain in body weight and the remaining animal showed expected gain in body weight during the study. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0.0, 0.0, 0.0 for cornea score; 0.0, 0.0, 0.0 for iris score; 0.3, 0.3, 0.3 for conjunctivae score and 0.3, 0.3, 0.3 for chemosis score. In this study, the substance is not an eye irritant in male rabbits.
In a supporting study, 2,2-bis[(octanoyloxy)methyl]butyl decanoate (CAS No. 11138-60-6) was tested for its eye irritation potential according to OECD Guideline 405 (Clouzeau, 1990): 0.1 mL of the test material were instilled into the conjunctival sac of one eye of three New Zealand White rabbits. Animals were observed for 72 hours and observed effects were scored 24, 48 and 72 hours after instillation according to 84/499/EEC appendix V B5 (Draize). No effects, except for one animal with a very slight exudation reaction at the 24 h time point, were observed in any of the tested animals at any relevant observation interval.
Fatty acids, C5-10, esters with pentaerythritol (CAS No. 68424-31-7) were tested for eye irritation potential according to OECD Guideline 405 (Robinson, 1991): 0.1 mL of the test material was instilled into the conjunctival sac of one eye of three New Zealand White rabbits. Animals were observed for 72 hours. Irritation was scored 24, 48 and 72 hours after instillation according to the method of Draize. No corneal or iridial effects were observed. Conjunctival effects included slight redness (one animal) and slight discharge (one animal) were transiently seen approx. one hour after dosing but were completely reversible within the first 24 h.
Justification for selection of skin irritation / corrosion endpoint:
Reliable (k=1) study performed on the substance itself
Justification for selection of eye irritation endpoint:
Reliable (k=1) study performed on the substance itself
Justification for classification or non-classification
According to the CLP criteria for classification and labelling of dangerous substances the test item is not classified as a skin or eye irritant.
