- Executive summary:
The acute oral toxicity of TMPH was determined by administration of graded doses of the test material. Young adult albino rats (Wistar-derived) from the Institute's colony were used. The body weights of males varied from 194 to 373 g, those of femals from 157 to 220 g.
After some preliminary observations, the test material was given by gavage, as a 10% (v/v) dilution in propylen (sic) glycol to groups of five male and five female rats in single doses of 6.0, 7.2, 8.6, 10.3 or 12.4 ml/kg body weight.
Within a few hours after dosing the rats showed sluggishness and decreased activity. Thereafter, most of the rats lost consciousness. deaths occurred between 8 hours and 3 days after treatment. Thereafter, the survivors recovered gradually and looked quite healthy again at the end of the observation period.
Macroscopic examination of the survivors at autopsy revealed rounded edges of the livers in some of the rats. No other treatment-related gross alterations were seen.
From the mortality-figures the LD50 of TMPH was calculated to be 0.92 ml per kg body weight with 0.87 and 0.96 as the 95% confidence limits. Therefore, the material can be classified as slightly toxic.

- Details on inhalation exposure:
- The exposure chamber consists of a horizontally placed glass cylinder (0.90 x 0.15 m) with sampling ports at both ends and contains a perforated stainless steel frame-work for separate accomodation of the rats.
Samples were analysed by means of gas-liquid chromatography, using an Intersmat gas-chromatograph loaded with a SE30 column (0.70 m, ø 1/2 cm), and detected with a flame ionisation detector.
Column-detection and injection temperatures were 75, 85 and 90 °C respectively.
The test compound was gauged by using a 4% solution in acetone. - Analytical verification of test atmosphere concentrations:

- Details on study design:
- The dynamic atmosphere for the inhalation experiment was formed by passing air (relative humidity 50%) through various columns - airflow per column 1 l/min - containing chromosorb W, AW, saturated with the test substance. Five columns were used in parallel, giving an eventual airfow of 5 l/min (the minimum quantity required to prevent condensation of vapou (H2O)) through the exposure chamber. The temperature inside the cylinder was 24 °C.
A group of five male and five females rats was exposed to an atmosphere saturated with T.M.P.H. for four hours. After the exposure the rats were returned to their living-cages and provided with food and tap water ad libitum during an observation period of 14 days. - Statistics:

- Executive summary:
The acute inhalation toxicity of T.M.P.H. was studied in rats, by exposing them to an atmosphere saturated with the test material for a period of four hours.
The dynamic atmosphere for the inhalation experiment was formed by passing air (relative humidity 50%) through various columns - airflow per column 1 l/min - containing chromosorb W, AW, saturated with the test substance. Five columns were used in parallel, giving an eventual airfow of 5 l/min (the minimum quantity required to prevent condensation of vapou (H2O)) through the exposure chamber. The temperature inside the cylinder was 24 °C.
A group of five male and five females rats was exposed to an atmosphere saturated with T.M.P.H. for four hours. After the exposure the rats were returned to their living-cages and provided with food and tap water ad libitum during an observation period of 14 days.
Exposure of the rats to an atmosphere saturated with T.M.P.H. - viz. 480 ppm (2.85 mg/l) under the experimental conditions - caused no mortality. From the start of the exposure the animals were restless. After half an hour they closed their eyes and had wet noses. The severity of the effects increased during the exposure period. After two hours mouth breathing was observed as well as some incoordination of movement. The female rats have been recovered one day after the exposure; the males however, needed about two days before they behaved normally again.
Since no mortality occurred during the subsequent observation period of 14 days, no LD50 value could be determined. From the results of the present study it can be concluded that the 4-hour LC50 of T.M.P.H. exceeds 480 ppm (2.85 mg/l) but is expected to be less than 10 mg/L.

- Details on test animals or test system and environmental conditions:
- Three male and three female Wistar (RccHan:WIST) strain rats were supplied by Harlan Laboratories UK Ltd., Oxon, UK. On receipt the animals were randomly allocated to cages. The females were nulliparous and non pregnant. After an acclimatisation period of at least five days the animals were selected at random and given a number unique within the study by indelible ink-marking on the tail and a number written on a cage card. At the start of the study the animals weighed at least 200 g, and were eight to twelve weeks of age. The weight variation did not exceed ±20% of the mean weight for each sex.
The animals were housed in suspended solid floor polypropylene cages furnished with wood flakes. The animals were housed individually during the 24 hour exposure period and in groups of five, by sex, for the remainder of the study. Free access to mains drinking water and food (2014C Teklad Global Rodent diet supplied by Harlan Laboratories UK Ltd., Oxon, UK) was allowed throughout the study. The diet, drinking water and bedding were routinely analysed and were considered not to contain any contaminants that could reasonably be expected to affect the purpose or integrity of the study.
The temperature and relative humidity were set to achieve limits of 19 to 25°C and 30 to 70% respectively. Any occasional deviations from these targets were considered not to have affected the purpose or integrity of the study. The rate of air exchange was at least fifteen changes per hour and the lighting was controlled by a time switch to give twelve hours continuous light (06:00 to 18:00) and twelve hours darkness.
The animals were provided with environmental enrichment items which were considered not to contain any contaminant of a level that might have affected the purpose or integrity of the study. - Type of coverage:
- semiocclusive
- Vehicle:
- unchanged (no vehicle)
- Details on dermal exposure:
- The calculated volume of test item, as received, was applied as evenly as possible to an area of shorn skin (approximately 10% of the total body surface area) using a graduated syringe.
- Duration of exposure:
- 24 hours

- Details on study design:
- On the day before treatment the back and flanks of each animal were clipped free of hair.
Using available information on the toxicity of the test item, a single group of animals was treated as follows:
Dose Level(mg/kg) Specific Gravity Dose Volume(ml/kg) Number of Rats (Female)
2000 0.889 2.25 3
The calculated volume of test item, as received, was applied as evenly as possible to an area of shorn skin (approximately 10% of the total body surface area) using a graduated syringe. A piece of surgical gauze was placed over the treatment area and semi occluded with a piece of self adhesive bandage. The animals were caged individually for the 24 hour exposure period. Shortly after dosing the dressings were examined to ensure that they were securely in place.
After the 24 hour contact period the bandage was carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with arachis oil BP to remove any residual test item.
As no mortalities were noted a further group of three males was similarly treated with the test item at a dose level of 2000 mg/kg bodyweight to give a total of three males and three females. The animals were caged individually for the 24 hour exposure period. After the 24 hour contact period the bandages were carefully removed and the treated skin and surrounding hair wiped with cotton wool moistened with arachis oil BP to remove any residual test item.
The animals were housed in groups of three by sex for the remainder of the test period.
The animals were observed for deaths or overt signs of toxicity ½, 1, 2 and 4 hours after dosing and subsequently once daily for fourteen days.
After removal of the dressings and subsequently once daily for fourteen days, the test sites were examined for evidence of primary irritation and scored according to the following scale from Draize J H (1977) "Dermal and Eye Toxicity Tests" In: Principles and Procedures for Evaluating the Toxicity of Household Substances, National Academy of Sciences, Washington DC p.31:

- Executive summary:
Introduction. The study was performed to assess the acute dermal toxicity of the test item in the Wistar strain rat. At the request of the Sponsor, for ethical reasons and in order to minimise the number of animals required, the study design was based on the OECD 423 Acute Oral Toxicity Study in the Rat – Acute Toxic Class Method, using three animals for each required step.
Method. A group of three females was given a single, 24-hour, semi‑occluded dermal application of the undiluted test item to intact skin at a dose level of 2000 mg/kg bodyweight. Based on the results of the initial test a further group of three males was similarly treated. Clinical signs and bodyweight development were monitored during the study. All animals were subjected to gross necropsy.
Mortality. There were no deaths.
Clinical Observations. Red/brown staining around the snout was noted thirty minutes after dosing in one male. No other signs of systemic toxicity were noted.
Dermal Irritation. Signs of dermal irritation noted were very slight erythema, blanching of the skin, haemorrhage of dermal capillaries, crust formation, scabbing, glossy skin and scab lifting to reveal glossy skin.
Bodyweight. All animals showed expected gains in bodyweight over the study period.
Necropsy. No abnormalities were noted at necropsy.
Conclusion. The acute dermal median lethal dose (LD50) of the test item in the Wistar strain rat was found to be greater than 2000 mg/kg bodyweight.

Evaluation of Data
Data evaluations included the relationship, if any, between the exposure of the animal to the test item and the incidence and severity of all abnormalities including behavioural and clinical observations, gross lesions, bodyweight changes, mortality and any other toxicological effects.
Using the mortality data obtained, an estimate of the acute dermal median lethal dose (LD50) of the test item was made.
