Endpoint summary

Description of key information
The read across for substance, CAS: 118685 -22-6; EC: 453-490-7; is based upon the analogous substances to which basic form, degree of substitution of functional groups is not considered to effect the proposed read across for the endpoint of acute toxicity via the oral, dermal or inhalatory route. Based on the information available for the read across substances, the substance is not expected to cause acute toxicity via the oral, dermal or inhalatory route.
All available acute oral toxicity studies category resulted in an acute oral LD50 > 2000 mg/kg bw.
All available acute dermal toxicity studies resulted in acute dermal LD50 > 2000 mg/kg bw.
All available acute inhalation toxicity studies resulted in acute inhalation LC50 > 5.0 mg/L.

Acute Oral Toxicity
CAS 85116-93-4
An acute oral toxicity study (limit test) was conducted withFatty acids, C16-18 (even numbered), esters with pentaerythritol(CAS 85116-93-4) comparable to OECD Guideline 401 (Potokar, 1983). Reporting of test conditions and results was limited. The test substance was administered by gavage at a concentration of 2000 mg/kg bw to 2 male and female Wistar rats each. The animals were observed for 14 days following administration. No mortalities occurred during the study period. No significant signs of toxicity except for transient rough fur and reduced activity direct after dosing were observed. Normal weight gain was observed after dosing. Finally no macroscopic findings were found at necropsy. The acute oral LD50 was found to be greater than 2000 mg/kg bw.
CAS 67762-53-2
The acute toxicity via the oral route of Fatty acids, C5-9 tetraesters with pentaerythritol has been investigated in two studies with rats (CAS No. 67762-53-2).
An acute oral toxicity study (limit test) was performed according to OECD Guideline 420 (fixed dose procedure) (Zolyniene, 1999). Groups of 5 males and females fasted CD Sprague-Dawley rats received single oral gavage doses of 2000 mg/kg bw. The animals were observed for 14 days following administration. No mortalities occurred. One animal showed alopecia extremities on snout which was not considered treatment related. No further clinical signs of toxicity were reported. No effect on body weight was noted. Finally necropsy revealed no substance-related findings. Thus, the acute oral LD50 was found to be greater than 2000 mg/kg bw.
Another acute oral toxicity study (limit test) was performed comparable to OECD Guideline 401 (D’Aleo, 1984). The test substance was administered by gavage at a concentration of 15000 mg/kg bw to groups of 5 male and female Sprague-Dawley rats. The animals were observed for 14 days following administration. No mortalities occurred. All animals exhibited clear, oily perineal staining on the 1st, 2nd, and 3rd day following treatment. This condition normally regarded as an adverse effect, was considered to be a consequence of the high dose level administered and not considered a toxic sign. No further clinical signs of toxicity were reported. The acute oral LD50 was found to be greater than 15000 mg/kg bw.
In summary, the oral LD50 of Fatty acids, C5-9 tetraesters with pentaerythritol is greater than 2000 mg/kg bw.
CAS 68424-31-7
The study conducted with Fatty acids, C5-10, esters with pentraerythritol (CAS No.68424-31-7) (Robinson, 1991) with limitations (reduced animal number), revealed but revealed no mortality and no other toxic effects, but an initial weight loss after treatment of rats with 2000 mg/kg bw. However this effect was completely reversible and the animals showed subsequently normal body weight gain.
Acute Inhalation Toxicity
CAS 68424-31-7
An acute inhalation toxicity study was performed with Fatty acids, C5-10, esters with pentraerythritol (CAS 68424-31-7) comparable to OECD Guideline 403. 5 male and female Alpk:APfSD rats were exposed for 4 hours to 5.0 mg/L test substance aerosol by nose only inhalation (Parr-Dobrzanski, 1994). The test substance caused no mortality, body weight changes or abnormalities in necropsy during the 15 day study period. Some clinical signs were noticed, which consisted of hunched position, chromodacryorrhea, piloerection, staining around nose and wet fur. These signs however occurred during or just after exposure and were clearly consistent with the use of restraint for exposure. The LC50 was therefore found to be greater than 5.1 mg/L.
Acute Dermal Toxicity
CAS 71010-76-9
An acute dermal toxicity study (limit test) was performed on Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid (CAS 71010-76-9) comparable to OECD Guideline 402 and GLP (Mallory, 2006). 5 male and female Sprague-Dawley rats were exposed to 2000 mg test substance /kg bodyweight for 24 hours on the back skin under semiocclusive conditions. The observation period was 14 days. No clinical signs of systemic toxicity were noted in any animal during the study period. Body weight gain and necropsy at study termination revealed no abnormalities. Thus, the acute dermal LD50 in rats for Decanoic acid, mixed esters with heptanoic acid, octanoic acid, pentaerythritol and valeric acid was found to exceed 2000 mg/kg bw.
