SCORING SYSTEM: EEC Ocular Evaluation Criteria
TOOL USED TO ASSESS SCORE: auxiliary light source, fluorescein
The eyes were macroscopically examined with the aid of an auxiliary light source for signs of irritation at 1, 24, 48 and 72 hours after dosing. Following macroscopic observations at the 24-hour scoring interval, the fluorescein examination procedure was repeated on all test and control eyes and any residual test article was gently rinsed from the eye at this time (if possible) using physiological saline. If any fluorescein findings were noted at 24 hours, a fluorescein exam was conducted on the affected eyes at each subsequent interval until a negative response was obtained. Any unusual observations and/or mortality were recorded. General health/mortality checks were performed twice daily. Individual body weights were obtained for each animal prior to dosing on day 0. - Irritation parameter:

- Irritant / corrosive response data:
- Exposure to the test substance produced corneal opacity in 4/6 test eyes at the 1-hour scoring interval. The corneal opacity resolved in all test eyes by the 24-hour scoring interval. Iritis was observed in 6/6 test eyes at the 1-hour scoring interval and resolved completely in all test eyes by the 48-hour scoring interval. Conjunctivitis (redness, swelling and/or discharge) was noted in 6/6 test eyes at the 1-hour scoring interval. The conjunctival irritation resolved completely in all test eyes by the 72-hour scoring interval. Additional ocular findings included slight dulling of the normal luster of the cornea which was noted in 2/6 test eyes.
A mechanical abrasion was observed in 1/6 control eyes during the fluorescein examination, but was not considered to be significant due to its transient nature. No corneal opacity, iritis or conjunctivitis was observed in the control eyes. - Other effects:
- None reported.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- In the in vivo eye irritation study with DTPMP (1-3Na), conducted according to OECD Test Guideline 405 and in compliance with GLP, DTPMP (1-3Na) was concluded to be not irritating to the eyes of rabbits.

Additional information
Skin irritation
In the key in vivo skin irritation study with DTPMP (1-3Na), conducted according to OECD Test Guideline 404 and in compliance with GLP, DTPMP (1-3Na) was not irritating to rabbit skin (Springborn Laboratories, 2000a reliability score 1). In the study, 0.5 ml of undiluted DTPMP (1-3Na) (aqueous solution containing 46.9% w/w active acid) was applied onto the skin of 6 rabbits for 4 hours under semi-occlusive dressing. At the end of the exposure period residual test substance was removed using gauze moistened with deionised water followed by dry gauze. Any unusual observations and/or mortality were recorded. General health checks were performed twice daily. Individual body weights were obtained prior to dosing. Very slight to well-defined erythema on 6/6 test sites and very slight oedema on 3/6 test sites were observed at the 1-hour scoring interval. The mean erythema score for animal #1 was 1 at 24/48/72 hours, while the mean erythema scores for animals #2, #3 and #4 were 0.33. The mean oedema skin reaction scores for animals #1, #2 and #3 were also 0.33 at 24/48/72 hours. The dermal irritation had resolved completely in all animals by day 10.
Eye irritation
In the key in vivo eye irritation study with DTPMP (1-3Na), conducted according to OECD Test Guideline 405 and in compliance with GLP, DTPMP (1-3Na) was concluded to be not irritating to the eyes of rabbits (Springborn Laboratories, 2000b, reliability score 1). In the study, 0.1 ml of undiluted DTPMP (1-3Na) (aqueous solution containing 46.9% w/w active acid) was instilled into the eyes of 6 rabbits. The eyes were macroscopically examined with the aid of an auxiliary light source for signs of irritation at 1, 24, 48 and 72 hours after dosing. Any unusual observations and/or mortality were recorded. General health/mortality checks were performed twice daily. Individual body weights were obtained for each animal prior to dosing on day 0. Exposure to the test substance produced corneal opacity in 4/6 test eyes at the 1-hour scoring interval. The corneal opacity resolved in all test eyes by the 24-hour scoring interval. Iritis was observed in 6/6 test eyes at the 1-hour scoring interval and resolved completely in all test eyes by the 48-hour scoring interval. Conjunctivitis (redness, swelling and/or discharge) was noted in 6/6 test eyes at the 1-hour scoring interval. The conjunctival irritation resolved completely in all test eyes by the 72-hour scoring interval. Additional ocular findings included slight dulling of the normal lustre of the cornea which was noted in 2/6 test eyes. A mechanical abrasion was observed in 1/6 control eyes during the fluorescein examination, but was not considered to be significant due to its transient nature. No corneal opacity, iritis or conjunctivitis was observed in the control eyes.
Justification for classification or non-classification
Based on the available data, DTPMP (1-3Na) does not require classification for skin or eye irritation according to Regulation (EC) No 1272/2008.
