Description of key information
Two reliable studies are available to evaluate the irritant potential of Diethylamine modified ethoxylated trimethylolpropane triacrylate.
Diethylamine modified ethoxylated trimethylolpropane triacrylate is slightly irritant for skin (Shakleton 1982) and irritant for eyes (Van Huygevoort 2002).
No data is available on irritation potential on respiratory tract.

0.5 ml of the test material was applied to each of two 2.5 cm square surgical lint pads attached to "sleek" plastic adhesive wrapping. The lint suares were then placed in contact with the animal's skin, one lint square in contact with abraded skin and one lint square with intact skin, bilateral to the midline, and secure in position by the attached "Sleek" adhesive tape. The entire trunk of the animal was then encircled with a length of elastic adhesive bandage 7.5 cm wide. - Duration of treatment / exposure:
- 24h
- Observation period:
- The reaction sites were assessed at 1 hour and at 48 hours after patch removal.
- Number of animals:
- 6
- Details on study design:
- At least one hour before dosing the rabbits were placed in restraining stocks and the dorsal surface of the rabbits closely clipped ove an area consisting of approximately 10% of the total surface area, using an Oster model A.2 clipper with Angra blade.
The left flank was then lightly abraded with the point of 25 x 0.6 mm sterila disposable hypodermic needle. The abrasions were sufficiently deep to damage the stratum corneum but not to penetrate the dermis. the skin of the right flank remainded intact.
After a contact period of 24 hours the adhesive tapes and lint patches were removed from the animals. One hour was then allowed to permit irritation from the adhesive tapes to subsade then the reaction sites were assessed using the scoring system of Draize.
The values obtained for erythema at both abraded and intact sites at the 24 and 72 hour readings were summed and the total divided by six, the number of rabbits, to give an average score for erythema. The values obtained for oedema were treated in a similar manner to give an average score for aedema. A primary irritation score was calculated by adding the total value obtained for erythema to tje total of value obsained for oedema dividing by six to give an average of the total score. This average was then divided by four to give a value referred to as the primary irritation score. - Irritation parameter:

- Executive summary:
In an eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP, 3 healthy male rabbits of the New Zealand White strain were exposed to 0.1 mL of Diethylamine modified ethoxylated trimethylolpropane triacrylate in one eye, while the contralateral eye remained untreated and served as control. The study was started by treatment of a single rabbit (sentinel). The two other animals were treated in a similar manner 21 days later, after considering the degree of eye irritation observed in the first animal. The eyelids were then gently held together for about one second to prevent loss of the test material, and then released. The eyes were examined 1 and 24 h after instillation. After 24 h observation, 2% fluorescein in water was instilled into both eyes of each animal to quantitatively determine corneal epithelial damage. The eyes were also examined 48 and 72 h, 7 and 14 days after the treatment. Draize (1977) scoring system was followed to grade the ocular reactions.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. Corneal injury was seen as opacity (maximum grade 1) and epithelial damage (maximum 75% of the corneal area) leads to development of pannus (neovascularisation of the cornea) in one animal 7 days after instillation. Corneal injury had resolved within 7 days in two animals and within 14 days in the other animal. Iridial irritation (grade 1) was observed in all animals and had resolved within 72 h. Irritation of the conjunctivae was seen as redness, chemosis and discharge, which had completely resolved within 7 days in one animal and within 14 days in the other two animals. Reduced elasticity of the eyelids was noted in one animal 72 h after instillation. Remnants of the test substance were present on the outside of the eyelids of one animal on Days 1, 2 and 3. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 1, 1, 1 for cornea score; 0.7, 0.7, 0.7 for iris score; 2.7, 2.7, 2.7 for conjunctivae score and 2.3, 2, 2 for chemosis score. In this study, Diethylamine modified ethoxylated trimethylolpropane triacrylate (ACTILANE 715) is an eye irritant on male rabbits.
Under the test conditions, Diethylamine modified ethoxylated trimethylolpropane triacrylate is Irritating to eyes.

Additional information
Skin irritation (Haynes 1982)
The objective of this study was to investigate the degree of irritation produced to the abraded and intact skin of 6 albino rabbits following 24 hours occluded contact with Diethylamine modified ethoxylated trimethylolpropane triacrylate.
Erythema and/or oedema were observed in all animals exposed to the substance (intact and abraded skin). However the effect are not severe, each score is equal or smaller than 2 (out of 4).
Diethylamine modified ethoxylated trimethylolpropane triacrylate is considered as slightly irritant but it is not classified as skin irritant according to CLP criteria.
Eye irritation (Van Huygevoort 2002)
In an eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP, 3 healthy male rabbits of the New Zealand White strain were exposed to 0.1 mL of Diethylamine modified ethoxylated trimethylolpropane triacrylate in one eye, while the contralateral eye remained untreated and served as control.
No symptoms of systemic toxicity were observed in the animals during the test period and no mortality occurred. Corneal injury was seen as opacity (maximum grade 1) and epithelial damage (maximum 75% of the corneal area) leads to development of pannus (neovascularisation of the cornea) in one animal 7 days after instillation. Corneal injury had resolved within 7 days in two animals and within 14 days in the other animal. Iridial irritation (grade 1) was observed in all animals and had resolved within 72 h. Irritation of the conjunctivae was seen as redness, chemosis and discharge, which had completely resolved within 7 days in one animal and within 14 days in the other two animals. Reduced elasticity of the eyelids was noted in one animal 72 h after instillation. Remnants of the test substance were present on the outside of the eyelids of one animal on Days 1, 2 and 3. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 1, 1, 1 for cornea score; 0.7, 0.7, 0.7 for iris score; 2.7, 2.7, 2.7 for conjunctivae score and 2.3, 2, 2 for chemosis score.
In this study, Diethylamine modified ethoxylated trimethylolpropane triacrylate is an eye irritant on male rabbits.
Justification for classification or non-classification
Based on the available data, no classification for skin irritation of the registered substance is required according to the Regulation EC N°1272/2008.
Based on the available data, the registered substance should be classified as eye irritating (Eye irrit.2, H319) according to the Regulation EC N°1272/2008.
