The suction LC50 of ADDUKT TI180-MXDA is greater than 5.0 mg/L.

Executive summary:

Purpose:

To evaluate the toxic effects and reversibility of ADDUKT TI180-MXDA by observing functional and morphological changes after inhalation administration of ADDUKT TI180-MXDA at dose of 5.0 mg/L to SD rats. This test will also provide information for both the acute toxicity classification and sub-chronic exposure doses.

 

Method:

10 rats (5♂and 5♀) were employed in acute inhalation toxicity test. The test animals were weighed before exposure and placed in the container. Rats were infected at the dose of 5.0 mg/L after balancing test concentration for 4 hours. Animals were daily observed for 14 days. All observations from individual rat were systematically recorded. Body weight of each animal was recorded prior to administration (recorded as d0), d1, d3, d7 and d14 respectively. All test animals should be subjected to gross necropsy. The observation of heart, lung, kidney, Iiver, spleen, gastrointestinal tract and other organs were performed to make sure whether there were any hemorrhage and edema.

 

Result:

No obvious toxicities were observed on test rats infected by ADDUKT TI180-MXDA at the dose of 5.0 mg/L. Body weights increased significantly during the experimental period. No obvious abnormalities of test rats induced by ADDUKT

TI180-MXDA were observed by necropsy at the end of study period.

 

Conclusion:

Under the present experimental conditions, rats were observed no obvious toxicities after infecting with the test substance ADDUKT TI180-MXDA (batch number: #VPE 1724/18) at the dose of 5.0 mg/L. The suction LC₅₀of ADDUKT TI180-MXDA is greater than 5.0 mg/L.

Details on test animals or test system and environmental conditions:

During the treatment, the animals were kept in individual cages. On D1, the animals were put into their cage by 5. The rats were kept in solid-bottomed clear polycarbonate cages with a stainless steel mesh lid. Each cage contains dust free weed shavings which were changed at least 2 times a week. Each cage was installed in conventional air conditioned animal husbandry. The temperature and relative humidity of the main test were controlled to remain within target ranges of 19 to 25°C and 30 to 70%, respectively. The rate of air exchange was approximately thirteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light (07.00 to 19.00) and twelve hours darkness.

Type of coverage:

other: gauze dressings

Vehicle:

other: dimethylsulfoxide

Details on dermal exposure:

Approximately 24 hours before the treatment, fur was removed from the dorsal area of the trunk of the test animals by clipping. At least 10 per cent of the body surface area was clear for the application of the test item Addukt TI 65 - MXDA. 2.0053 g and 4.0012 g of the test item was weighed and dimethylsulfoxide was added to a 10 and 20 mL volumetric flask, respectively. The preparation was magnetically stirred and heated at around 50°C to obtain a whitish to yellow solution just before the administration. The preparation was administered under a volume of 10 mL/kg body weight, during 24 hours. After 24-hours exposure period, the gauze dressings were removed and the treated areas were rinsed with distilled water and paraffin oil.

In accordance with the Regulation EC No. 1272/2008, the test item does not have to be classified. No signal word or hazard statement is required.

Executive summary:

The test item Addukt TI 65 - MXDA was applied onto the intact skin of 10 Sprague Dawley rats (5 males and 5 females) at the single dose of 2000 mg/kg body weight. The experimental protocol was established on the basis of the official method as defined in the OECD guideline No. 402 dated February 24th, 1987 and the test method B.3 of the Council regulation No. 440/2008 of 30 May 2008. No mortality occurred during the study. No systemic clinical signs related to the administration of the test item were observed.

Cutaneous reactions (erythema and dryness) were noted from day 2 in all animals and were totally reversible on day 8. A white coloration of the treated site was noted from 24 hours post-dose in all animals and was totally reversible on day 2. The body weight evolution of the animals remained normal throughout the study. The macroscopic examination of the animals at the end of the study did not reveal treatment-related changes. In conclusion, the LD50 of the test item Addukt TI 65 - MXDA is higher than 2000 mg/kg body

weight by dermal route in the rat. According to the criteria for classification, packaging and labelling of dangerous substances and preparations in accordance with the E.E.C.
