- Executive summary:
The study was performed to assess the acute oral toxicity of Trichloroacetyl chloride (TCAC) in the rat. The method followed was similar to the OECD Guideline 401 and the study was not performed in accordance with GLP.
TCAC was administered to five Sprague-Dawley rats of each sex. The animals were exposed to single oral dose levels of 1000, 1200, 1500, 1600 and 1800 mg/kg. All animals were subjected to observations and determination of body weight. Macroscopic examination was performed on the day of death. At 1800 mg/kg, 8 animals died. Autopsies revealed hemorrhagic stomach, lungs and thymus. At 1600 mg/kg, 4 females died between Day 1 and 2 and one male at Day 12. At the autopsy, animals presented hemorrhagic lesions onto lungs and stomach. For the male died at Day 12, the autopsy revealed that the stomach was joint to the peritoneum, kidney were granular and hemorrhagic aspect, thymic involution. At 1500 mg/kg, one female died and the autopsy revealed hemorrhagic lesions onto lungs and stomach. At 1000 and 1200 mg/kg, there is no mortality.
The acute oral LD50 value of TCAC was 1643 mg/kg according to Probit method or Litchfield and Wilcoxon method.
In these test conditions, TCAC is classified harmful if swallowed according to the UN GHS and CLP criteria.

The study was performed to assess the acute dermal toxicity of Trichloroacetyl chloride (TCAC) in the rat. The method followed was similar to OECD Guideline 402 and the study was not performed in accordance with GLP.
Ten animals (5 males and 5 females) were exposed to single dermal dose level of 2000 mg/kg. All animals were subjected to observations and determination of body weight. Macroscopic examination was performed after terminal sacrifice. No mortality occurred at the dose level of 2000 mg/kg and there was no clinical sign. Macroscopic examination of the main organs of the animals revealed no apparent abnormalities except cutaneous reactions (Day 7: purulent lesions - Day 14: persistence of skin lesions).
The acute dermal LD50 value of TCAC was higher to 2000 mg/kg.
In these test conditions, TCAC is not classified according to the UN GHS and CLP criteria.

Severe erythema and with eschar formation:
* slight eschar = 4
* extended eschar (more than 50% of the surface application) = 8
* Oedema formation:
No oedema = 0
Very slight oedema (barely perceptible) = 1
Slight oedema (edges of area well-defined by definite raising) = 2
Moderate oedema (raised approximately 1 millimetre) = 3
Severe oedema (raised more than 1 millimetre and extending beyond the area of exposure) = 4
The numerical rating scale above allows the determination of a "Primary Skin Irritation Index"; this index is equal to the sum of the individual values which express the intensity of the erythema and the intensity of the edema, 25 hours and 72 hours after the application, both on the intact skin and on the scarified skin, divided by 16 (number of treated rabbits x 4). The maximum value of the primary skin irritation index is 12. - Irritation parameter:
- primary dermal irritation index (PDII)
- Basis:
- mean
- Time point:
- other: 25 and 72 hours
- Score:
- 8.63
- Reversibility:
- not specified
- Irritant / corrosive response data:
- All animals presented a well visible erythema exceeding the application area at time 25 hours.
- Normal area:
All animals presented oedema and erythema (scored 3, 4 or 8) at time 25 and 72 hours. One rabbit presented an extended eschar at time 25 hours and a very important necrosis at time 72 hours.
- Scarified area:
All animals presented oedema and erythema (scored 3, 4 or 8) at time 25 and 72 hours. One rabbit presented a very important necrosis at time 72 hours. - Interpretation of results:
- Category 1 (corrosive) based on GHS criteria
- Conclusions:
- In these test conditions, Thrichloroacetyl chloride is considered as corrosive to skin.
- Executive summary:
A skin irritation study was performed with Trichloroacetyl chloride (TCAC) in rabbits. The method followed was similar to the OECD Guideline 404 and the study was not performed in accordance with GLP. TCAC was applied on scarified or normal skin for 24 hours under occlusive coverage. Examinations were performed at 25 hours (1 hour after removal of the tape) and 72 hours after application. Erythema (and eschar) and oedema formation were scored. All animals presented a well visible erythema exceeding the application area at time 25 hours. All animals presented oedema and erythema (scored 3, 4 or 8) at time 25 and 72 hours. One rabbit presented a very important necrosis at time 72 hours.
TCAC is classified corrosive to skin according to the UN GHS and CLP criteria.

SCORING SYSTEM:
Conjonctivae
A = chemosis (oedema)
- none = 0
- slight = 1
- pronounced, with eversion of the eyelids = 2
- with half-closed eyelids = 3
- with closed or almost closed eyelids = 4
B = lacrimal secretions
- none = 0
- slight = 1
- with moistening of the hairs around the eyelids = 2
- same observation, but on large surfaces around the eye = 3
C = redness of the palpebral conjunctiva
- normal appearance = 0
- vessels significantly more injected than normal = 1
- diffuse redness with vessels difficult to individualize = 2
- color dark red diffuse = 3
Iris
A1 = damage of this iris
- normal appearance = 0
- aspect much more pleated than normal, congestion, swelling, circumcorneal injections (or only one of these manifestations), but iris still reacting to light (even weakly or slowly) = 1
- no reaction to light, hemorrhage, significant destruction (or only one of these manifestations) = 2
A2 = degree of opacity
- normal appearance = 0
- loss of shine or polish, but clearly visible iris details = 1
- translucent area, with slightly obscured iris details = 2
- opalescent area, with invisible iris details and barely visible pupil contour = 3
- iris and pupil invisible = 4
B2 = surface of the opacity
- less than or equal to a quarter (but not zero) = 1
- between one-quarter and one-half = 2
- between one-half and three quarters = 3
- more than three quarters = 4
The coefficients of the conjunctival damage, the iris damage and the corneal damage allow to determine 3 indices of ocular irritation:
- the individual eye irritation index (= IEI), the maximum value of which equals 110, is equal to eacg time, for each rabbit, to
2 (A + B + C) + 5A1 + 5A2B2
- the mean ocular irritation index (= MOI) is the average, at each time, of the IEI of the 4 treated rabbits;
- the acute eye irritation index (= AEI) is the highest MOI obtained within 7 days of observation.
The interpretation of the results is made from these 3 index and is drawn from KAY and CALANDRA (J. Soc. Cosmet. Chem., 13, 281 (1962): "Interpretation of eye-irritation tests").

- Irritant / corrosive response data:
- The importance of injuries did not allow calculating mean scores for chemosis, corneal opacity and iritis.
Observations: Conjunctival chemosis (grade 4) were observed in all animals at 1h and remained present at the end of the observation study (day 7). Corneal opacity was observed in all of the animals and remained present at day 1 and day 2 to day 7 the observation of corneal opacity was impossible because of severe chemosis. One rabbit presented a necrose on day 7. - Interpretation of results:
- Category 1 (irreversible effects on the eye) based on GHS criteria
- Conclusions:
- Under the test conditions, Trichloroacetyl chloride is considered as highly irritant.
- Executive summary:
An eye irritation study was performed with Trichloroacetyl chloride (TCAC) in rabbits. The method followed was similar to the OECD Guideline 405 and the study was not performed in accordance with GLP. A single dose of TCAC in its originak form was introduced into the conjunctival sac of the left eye. The right eye was not treated and served as control. The eyes were not rinsed after administration of TCAC.
Ocular reactions were observed 1 hour and 1, 2, 3, 4 and 7 days after the administration.
The importance of injuries did not allow calculating mean scores for chemosis, corneal opacity and iritis.
Conjunctival chemosis (grade 4) were observed in all animals at 1h and remained present at the end of the observation study (day 7). Corneal opacity was observed in all of the animals and remained present at day 1 and day 2 to day 7 the observation of corneal opacity was impossible because of severe chemosis. One rabbit presented a necrose on day 7.
TCAC is classified corrosive to eyes according to the UN GHS and CLP criteria.
