No se registró mortalidad entre los animales tratados a la dosis de 2000 mg/kg.

 

La evolución del peso corporal medio de los animales tratados a la dosis de 2000 mg/kg fue normal. Sin embargo, en dos de las hembras se registró una ligera pérdida de peso corporal entre el primer y segundo dia del periodo de observación en el caso de una, y entre el segundo y séptimo dia en el caso de la otra hembra.

 

No se registraron alteraciones macroscopicas en las necropsias realizadas a todos los animales administrados a la dosis de 2000 mg/kg

Conclusions:

Single oral administration of MEA Polyboate 1:3 135 g/L to a group of four fasted rats at a dose level of 2000 mg/kg had no adverse effects. Accordingly, the acute median lethal oral dose and the minmum lethal oral dose to rats was shown to exceed 2000mg/kg bodyweight.

Executive summary:

Two male and female fasted rats were dosed with MEA Polyboate 1:3 135g/L at 2000 mg/Kg on day 1. The test article was dispersed in purified water at a concentration of 10% m/v and administered by oral lavage at a dose volume of 20 mL/Kg. All animals were killed on Day 8 and subsequently underwent a terminal macroscopic examination.

No animal died. There were no clinical signs of systemic toxicity. All rats made substantial body weight gains between day 1 and day 8. No macroscopic changes were apparent at necroscopy on day 8.

Single oral administration of MEA Polyboate 1:3 135 g/L to a group of four fasted rats at a dose level of 2000 mg/kg had no adverse effects. Accordingly, the acute median lethal oral dose and the minimum lethal oral dose to rats was shown to exceed 2000mg/kg bodyweight.

Source: Charles River UK, Kent, England
Outbred, SPF-quality
Young adult animals (approximately 10 weeks)
Weight at the Initiation of Dosing: 187 to 338 g.

On arrival, animals were group housed (up to 5 animals of the same sex together) in polycarbonate cages (Makrolon MIV type; height 18 cm.) and following assignment to the study, animals were individually housed in polycarbonate cages (Makrolon MIII type; height 18 cm.) containing sterilized sawdust as bedding material (Lignocel S 8-15, JRS - J.Rettenmaier & Söhne GmbH + CO. KG, Rosenberg, Germany) equipped with water bottles.

The animals were allowed to acclimate to the Test Facility toxicology accommodation for at least 5 days before the commencement of dosing.
Target temperatures of 18 to 24°C with a relative target humidity of 40 to 70% were maintained. The actual daily mean temperature during the study period was 21 to 22°C with an actual daily mean relative humidity of 43 to 69%. A 12 hour light/12 hour dark cycle was maintained. Ten or greater air changes per hour with 100% fresh air (no air recirculation) were maintained in the animal rooms.

For psychological/environmental enrichment, animals were provided with paper (Enviro-dri, Wm. Lillico & Son (Wonham Mill Ltd), Surrey, United Kingdom), except when interrupted by study procedures/activities.

Type of coverage:

occlusive

Vehicle:

unchanged (no vehicle)

Details on dermal exposure:

A single dose of test item was administered to the appropriate animals by dermal application on Day 1. One day before dosing, an area of approximately 5x7 cm on the back of the animals was clipped. The test item was applied in an area of approximately 10% of the total body surface, i.e. approximately 25 cm² for males and 18 cm² for females. The test item was held in contact with the skin with a dressing, consisting of a surgical gauze patch (Surgy 1D), successively covered with aluminum foil and Coban elastic bandage. A piece of Micropore tape was additionally used for fixation of the bandages in females only.

Duration of exposure:

The application period was 24 hours, after which the dressing was removed and the skin cleaned of residual test item using water or an appropriate vehicle.

Doses:

The dose level was 2000 mg/kg body weight.

No. of animals per sex per dose:

5 males and 5 females (females were nulliparous and non-pregnant)

Control animals:

no

Details on study design:

Throughout the study, animals were observed for general health/mortality and moribundity twice daily, in the morning and at the end of the working day.

Post-dose observations were performed at periodic intervals on the day of dosing (at least three times) and once daily thereafter. The observation period was 14 days. All the animals were examined for reaction to dosing. The onset, intensity and duration of these signs was recorded (if appropriate), particular attention being paid to the animals during and for the first hour after dosing.

Animals were weighed individually on Day 1 (pre-dose), 8 and 15.

All moribund animals and animals surviving to the end of the observation period were sacrificed by oxygen/carbon dioxide procedure. All animals assigned to the study were subjected to necropsy and descriptions of all internal macroscopic abnormalities were recorded.

Gross pathology:

Beginning autolysis was noted for the animal that died during the study, at macroscopic post mortem examination. Macroscopic post mortem examination of the other animals at termination did not reveal any abnormalities.

Interpretation of results:

GHS criteria not met

Conclusions:

The dermal LD50 value of MEA Polyborate 1:3 in Wistar rats was established to exceed 2000 mg/kg body weight.

Endpoint conclusion

Endpoint conclusion:

adverse effect observed

Justification for classification or non-classification

Oral route: Single oral administration of MEA Polyboare 1:3 135 g/L to a group of four fasted rats at a dose level of 2000 mg/kg had no adverse effects. Accordingly, the acute median lethal oral dose and the minimum lethal oral dose to rats was shown to exceed 2000 mg/kg bodyweight. Therefore, the substance is not classified for acute toxicity oral route according to GHS.

Dermal route: The dermal LD50 value of MEA Polyborate 1:3 in Wistar rats was established to exceed 2000 mg/kg body weight, therefore the substance is not classified for acute toxicity dermal route according to GHS.
