- Weight at study initiation: 250 to 279 g (males) and 175 to 203 g (females)
- Fasting period before study: Not applicable
- Housing: up to five rats of the same sex were accommodated in cages that conformed to the 'Code of Practice for the Housing and Care of Animals Used in Scientific Procedures' (Home Office, London, 1989). From the day prior to dosing (Day –1), each rat was individually housed in a similar cage. After completion of the Day 3 observations animals allocated to the main study were returned to group housing.

Results and discussion
- Preliminary study:
- A pair of animals (one male and one female) received a single dermal dose of test article at a dose level of 2000 mg/kg.,(no compound related mortality. was observed).
Effect levels
- Sex:
- male/female
- Dose descriptor:
- discriminating dose
- Effect level:
- > 2 000 mg/kg bw
- Based on:
- test mat.
- Mortality:
- There were no deaths.
- Clinical signs:
- other: There were no clinical signs of reaction to treatment.
- Gross pathology:
- Abnormalities noted at necropsy were confined to a sore appearance of the skin at the treatment site and an isolated incident of pale mucosal surface of the stomach.
- Other findings:
- Very slight to well-defined erythema was noted in all animals on Day 2. Very slight erythema was noted in two animals up to Day 6 and persisted in one animal until the end of the observation period.
Other adverse dermal reactions noted were brown discolouration of the skin, scabbing and new skin growth.
Applicant's summary and conclusion
- Interpretation of results:
- study cannot be used for classification
- Remarks:
- Migrated information
- Conclusions:
- The acute median lethal dermal dose of MonoFA_TETA_PAA_BADGE_BGE_Adduct to rats was found to exceed 2000 mg/kg.
The test material was considered to have no significant acute toxic risk in respect of its acute dermal toxicity and did not meet the criteria for classification according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). - Executive summary:
This study was conducted to determine the acute dermal toxicity of the test article, MonoFA_TETA_PAA_BADGE_BGE_Adduct, following a single (24 hour) semi-occluded topical application to the rat.
The test article was applied undiluted to the clipped dorsum of a group of five male and five female rats on Day 1. Each rat received a single topical application at a dose level of 2000 mg/kg. The treated areas of dorsum were covered by a semi-occlusive dressing for 24 hours. All animals were killed on Day 15 and subsequently underwent a full necropsy.
There were no deaths and no clinical signs of reaction to treatment.
Adverse dermal reactions noted were very slight to well-defined erythema, brown discolouration of the skin, scabbing and new skin growth.
All rats gained weight during the first and second weeks of the study except for one female which showed a slight loss in body weight during the first week.
Abnormalities noted at necropsy were confined to a sore appearance of the skin at the treatment site and an isolated incident of pale mucosal surface of the stomach.
The acute median lethal dermal dose of MonoFA_TETA_PAA_BADGE_BGE_Adduct to rats was found to exceed 2000 mg/kg.
The test material was considered to have no significant acute toxic risk in respect of its acute dermal toxicity and did not meet the criteria for classification according to the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
