During the 14 day observation period, no mortality occured and no signs for systemic toxicity were recorded. Slight to moderate erythema (grade 1 to 3) were noted, and incrustations occured in females exposed to 2000 mg/kg bw. The mean body weight of the animals increased within the normal range throughout the study period. No macroscopic pathologic abnormalities were noted. Accordingly, the acute dermal median lethal dose (LD50) was determined to be higher than 2000 mg/kg bw.

Additional information
Oral acute toxicity study (1993):
An acute toxicity test (toxic class method) according to EU method B.1. modified according to the BGA modell and similar to OECD 423 was performed under GLP conditions in 1993. A group of 6 fasted animals (3 males and 3 females) was given a single oral dose of test material preparation in aqua bidest at the dose level of 200 mg/kg bw. Another group of 3 females was treated in the same way with a dose of 2000 mg/kg bw.
The animals treated with 200 mg/kg bw did not show any mortality or symptoms. No abnormalities were noted at necropsy of animals sacrificed at the end of the study.
Signs of toxicity noted in females treated with 2000 mg/kg bw comprised poor general state, dyspnea, apathy, abdominal position, atonia, paresis, cyanosis and diarrhea. All females treated with 2000 mg/kg bw died 4 hours or 1 day after treatment. Necropsy findings of the animals that died was general congestion.
Under the conditions of this study, the range of LD50 after oral application was found to be greater than 200 mg/kg bw and less than 2000 mg/kg bw.
Dermal acute toxicity study (2011):
In an acute dermal toxicity study (Limit Test), 5 male and 5 female young adult Wistar rats per group were dermally exposed to test groups of 2000 and 500 mg/kg bw of 1,4-butanediylbis[oxy(2-hydroxy-3,1-propanediyl)] diacrylate (undiluted or preparation in olive oil) to the clipped skin (dorsal and dorso-lateral parts of the trunk) and covered by semiocclusive dressing for 24 hours. During the 14 day observation period, no mortality occured and no signs for systemic toxicity were recorded. Slight to moderate erythema (grade 1 to 3) were noted, and incrustations occured in females exposed to 2000 mg/kg bw. The mean body weight of the animals increased within the normal range throughout the study period. No macroscopic pathologic abnormalities were noted. Accordingly, the acute dermal median lethal dose (LD50) was determined to be higher than 2000 mg/kg bw.
Justification for classification or non-classification
Based on the available data, butane-1,4-diylbis(oxy-2-hydroxypropane-3,1-diyl) bisacrylate should be classified as Acute tox 4 (H302, oral route) according to the Regulation EC n°1272/2008.
Justification: Since the oral LD50 was greater than 200 mg/kg, but smaller than 2000mg/kg. No signs of toxicity were noted at 200 mg/kg and no mortality occurred, so that it is considered unlikely that half the animals would die when treated with 300 mg/kg.
Because no animals died after dermal application of up to 2000 mg/kg, no classification is required for dermal acute toxicity.
