- TEST SITE
Prior to application of the test article, the back and sides of each animal were clipped free of hair. The left side of each animal was abraded with a bent tip needle. Three abrasions, approximately 2-3 cm apart, extending the length of the exposure site were made. The abrasions were sufficiently deep to penetrate the stratum corneum, but not deep enough to produce bleeding. The right side of each animal remained intact.
EXPERIMENTAL DESIGN
The test article was used as received and dosed by volume, 0.5 ml/site, for a total dose of 1.0 ml/rabbit. The test article was applied to two areas, 1 intact and 1 abraded, on the prepared site, on the back of each of six rabbits.
The treated sites were covered with 2.5 cm square gauze patches which were secured with adhesive tape. The torso was wrapped with plastic which was secured with adhesive tape. The sites were occluded for 24 hours at which time the patches were removed.
TYPE AND FREQUENCY OF OBSERVATIONS
Animals were observed for skin reactions at 24 and 72 hours after application of the test article. Erythema and edema were scored according to the numerical Draize technique. Body weights were recorded pretest. Additional signs were described.
The general health of the animals was monitored at each observation time. - Irritation parameter:

- Executive summary:
The dermal irritation of TIPMDP was tested on 6 New Zealand Albino rabbits in a primary dermal irritation following the standards set forth by FHSA, 16 CFR 1500.3(c)(4). 0.5 ml of the test substance was applied to 1 intact and 1 abraded site on the clipped back for a total dose of 1.0 ml/rabbit. The sites were occluded for 24 hours. The skin reactions were evaluated by the Draize technique at 24 and 72 hours after dosing. Body weights were recorded pretest. The Primary Irritation Index was calculated.
Erythema , slight to well defined at 24 hours, was absent to slight at 72 hours. Edema, absent to well defined at 24 hours, was absent at 72 hours. Abnormal systemic signs of diarrhea and few feces were noted during the observation periods. The substance was not found to be irritating to the skin.

- Controls:
- other: The contralateral eye served as a control.
- Amount / concentration applied:
- 0.1 ml of the test article was placed by syringe or syringe-type applicator into the conjunctival sac which was formed by gently pulling the lower eyelid away from the eye. After instillation, the lids were held together briefly to insure adequate distribution of the test article. One eye of each rabbit was dosed. The contralateral eye served as a control.
- Duration of treatment / exposure:
- Once
- Observation period (in vivo):
- The treated eye of each rabbit was examined for irritation of the cornea, iris and conjunctiva on days 1, 2, 3, 7 and 14. Ocular reactions were graded according to the numerical Draize technique. Additional signs were described. Body weights were recorded pretest.
The general health of the animals was monitored at each observation time. - Number of animals or in vitro replicates:
- 6 females
- Details on study design:
- The primary eye irritation score for each rabbit was calculated from the weighted Draize scale. The method of calculation is indicated on the attached scale.
The irritation potential was determined by counting the number of rabbits with positive irritation on days 1, 2 or 3. Positive irritation is defined as any score for opacity or iritis, or 2 or more for redness or chemosis. The test article is an irritant if 4 or more rabbits had a positive score at any time period. - Remarks on result:

- Executive summary:
The eye irritation of TIPMDP was tested on 6 female New Zealand Albino rabbits in an eye irritation study following the standards set forth by FHSA, 16 CFR 1500.42. 0.1 ml of the test substane was placed into the conjunctival sac of one eye of each rabbit. The other eye was use as control eye. The eyes were not washed. The eyes were examined and scored by the Draize technique on days 1, 2, 3, 7 and 14. Body weights were recorded pretest. The primary eye irritation score for each rabbit, each day, was calculated. Corneal opacity and iritis, noted in 6/6 eyes, cleared by day 14. Moderate conjunctival irritation, noted in 6/6 eyes, persisted to day 14 in one eye. There were no abnormal physical signs noted during the observation period. The test substance is an eye irritant but not corrosive.

Additional information
Skin irritation
One reliable study is available for skin irritation/corrosion. In this study, TIPMDP was found to be not irritating.
Eye irritation
Two reliable studies are available for eye irritation (Moreno 1990 and 1993). The study performed in 1993 was choosen as key study as the batch tested during this study was a higher and a more representative purity. Based on the results of this study, TIPDMP is considered as irritating to eyes. Therefore, the classification "Eye irritation (H319)" is warranted according to Regulation (EC) 1272/2008.
Justification for classification or non-classification
For eye irritation, classification is warranted according to the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008 (Cat. 2; H319). Classification for skin irritation is not needed based on the available data.
