Endpoint summary
Administrative data
Description of key information
Oral: The acute oral LD50 obtained for the test item was found to be greater 2000 mg/kg bw.
Dermal: To assess the acute dermal toxicity of Sika Hardener LJ, read across was applied using toxicological data from the hydrolysis product 2,2-Dimethyl-3-lauroyloxy-propanal. Based on the findings of an acute dermal toxicity study, a single 24-hour dermal administration of the hydrolysis product did not induce any test item related adverse effects and a LD50 > 2000 mg/kg bw was derived.

In this acute oral toxicity study, two groups of female rats (Crl(WI)Br) were given a single oral dose of the test item SIKA Hardener LJ at a concentration of 2000 mg/kg bw. The starting dose was selected on the basis of the available information about the test item.
The acute toxic class method was carried out involving a stepwise procedure with the use of 2000 mg/kg bw as the starting dose in three female rats. No animal died in the first step at 2000 mg/kg bw dose level. Therefore, treatment with 2000 mg/kg bw was repeated on further three female rats. Again, no animal died in the second step, thus no further testing was required. The stopping criteria of Annex 2d of OECD Guideline No. 423 were met.
Animals were weighed, observed for lethality and toxic symptoms for 14 days after the treatment. Gross pathological examination was carried out on the 15th day after the treatment.
There were no effects on mean body weight and body weight gain. No clinical symptoms were observed and all organs of the animals treated with 2000 mg/kg bw dose proved to be free of treatment related gross pathological changes.
According of the results from this study the LD50 obtained for the test item was found to be o be greater 2000 mg/kg bw. Therefore, there is no classification required for the test item SIKA Hardener LJ.

- Gross pathology:
- In the male dose group of 2000 mg/kg bw, emphysema (4/5 male, 3/5 female) and pinprick-sized haemorrhages (1/5 male 2/5 female) were observed in the lungs. No macroscopic alterations due to the toxic effect of the test item were found. The pulmonary emphysema and the pinprick-sized haemorrhages observed during the necropsy might be related to the method of anaesthesia and are also observed in untreated animals.
- Interpretation of results:

The acute dermal toxicity study (Limit Test) according to OECD 402 was performed with 2,2-Dimethyl-3-lauroyloxy-propanal. Five male and 5 female CRL (WI) BR Wistar rats were treated (single 24-hour semi-occlusive dermal application) with undiluted 2,2-Dimethyl-3-lauroyloxy-propanal at a dose level of 2000 mg/kg bw. None of these animals died. Clinical signs or dermal symptoms were not observed during the 14 days post-treatment observation period. No effects on mean body weight and body weight gain were noted for these dose groups. Specific macroscopic alterations related to the toxic effect of the test item 2,2-Dimethyl-3-lauroyloxy-propanal were not found. The acute dermal LD50 value is above 2000 mg/kg bw in male and female CRL: (WI) BR rats.
