Interpretation of results:

Conclusions:

Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.

Executive summary:

In an eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP, 3 healthy female albino rabbits of the stock Chbb:HM (SPF) – Littlerussian were exposed to 0.1 mL of Bisphenol A ethoxylate diacrylate in one eye, while the contralateral eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined 1 h and 24 h after instillation. After the first 24 h reading fluorescein was instilled and eyes were examined for ocular lesions. After rinsing with 20 mL 0.9% sodium chloride solution, the eyes were examined again using UV -light to detect possible corneal damage. The eyes were also examined 48 and 72 h after the treatment. Draize (1977) scoring system was followed to grade the ocular reactions. 

One hour after application of the test article, animals showed conjunctival redness, chemosis and discharge different from normal. All the eyes were normal one day after instillation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for cornea score; 0, 0, 0 for iris score; 0, 0, 0 for conjunctivae score and 0, 0, 0 for chemosis score. In this study, Bisphenol A ethoxylate diacrylate is not an eye irritant on female rabbits.

 

Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.

Interpretation of results:

Conclusions:

Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.

Executive summary:

In an eye irritation study conducted similarly to the OECD Guideline 405 and in compliance with GLP, 3 healthy female rabbits of the New Zealand White strain were exposed to 0.1 mL of Bisphenol A ethoxylate diacrylate in one eye, while the contralateral eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined unwashed and the changes were observed at 1 h and 1, 2, 3 (equivalent to 24, 48 and 72 h), 4 and 7 days after instillation and graded according to the method of Draize (1977). 

No corneal damage or iridial inflammation was observed. Temporary mild conjunctival reactions only were seen. All the eyes were normal one day after instillation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for cornea score; 0, 0, 0 for iris score; 0, 0, 0 for conjunctivae score and 0, 0, 0 for chemosis score. In this study, Bisphenol A ethoxylate diacrylate is not an eye irritant on female rabbits.

Under the test conditions, Bisphenol A ethoxylate diacrylate is not classified as irritating to eyes.

Additional information

Skin irritation

Two reliable studies are available to evaluate the skin irritation potential of Bisphenol A ethoxylated diacrylate (Parcell 1993, Liggett 1992).

In both studies, a primary dermal irritation study was performed similarly to OECD Guideline 404 and in compliance with GLP. Three New Zealand White rabbits were dermally exposed to 0.5 mL of Bisphenol A ethoxylate diacrylate, under a semi-occlusive patch (25 mm X 25 mm) for 4 h to intact clipped skin of the dorso-lumbar region. After removal of the residual test material, animals were observed for 4 days. Irritation was scored by the method of Draize at Day 1 (approximately 60 min after removal of the dressings) and Days 2, 3 and 4 (equivalent to 24, 48 and 72 h) after exposure.

No dermal reactions and signs of toxicity to treatment were observed in any animal throughout the observation period. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were respectively 0, 0, 0 for erythema and 0, 0, 0 for oedema score.

In these both studies, Bisphenol A ethoxylated diacrylate is not a skin irritant on rabbits.

Eye irritation

Two reliable studies are available to evaluate the eye irritation potential of Bisphenol A ethoxylated diacrylate (Parcell 1993, Vaeth 2001).

In the first study (Vaeth 2001), eye irritation study conducted according to the OECD Guideline 405 and in compliance with GLP. Three healthy female albino rabbits of the stock Chbb:HM (SPF) – Littlerussian were exposed to 0.1 mL of Bisphenol A ethoxylate diacrylate in one eye, while the contralateral eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined 1 h and 24 h after instillation.After the first 24 h reading fluorescein was instilled and eyes were examined for ocular lesions. After rinsing with 20 mL 0.9% sodium chloride solution, the eyes were examined again using UV -light to detect possible corneal damage. Theeyes were also examined 48 and 72 h after the treatment. Draize (1977) scoring system was followed to grade the ocular reactions. 

One hour after application of the test article, animals showed conjunctival redness, chemosis and discharge different from normal.All the eyes were normal one day after instillation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for cornea score; 0, 0, 0 for iris score; 0, 0, 0 for conjunctivae score and 0, 0, 0 for chemosis score. In this study, Bisphenol A ethoxylate diacrylate is not an eye irritant on female rabbits.

In the second study (Parcell 1993), eye irritation study conducted similarly to the OECD Guideline 405 and in compliance with GLP, 3 healthy female rabbits of the New Zealand White strain were exposed to 0.1 mL of Bisphenol A ethoxylate diacrylate (SR 349) in one eye, while the contralateral eye remained untreated and served as control. The eyelids were then gently held together for one second before releasing. The eyes were examined unwashed and the changes were observed at 1 h and 1, 2, 3 (equivalent to 24, 48 and 72 h), 4 and 7 days after instillation and graded according to the method of Draize (1977). 

No corneal damage or iridial inflammation was observed. Temporary mild conjunctival reactions only were seen. All the eyes were normal one day after instillation. Mean individual scores at 24, 48 and 72 h after exposure for the 3 animals were 0, 0, 0 for cornea score; 0, 0, 0 for iris score; 0, 0, 0 for conjunctivae score and 0, 0, 0 for chemosis score.

In this study, Bisphenol A ethoxylated diacrylate is not an eye irritant on female rabbits.

Justification for classification or non-classification

No damage or irritation on the skin was observed in the rabbit study, Bisphenol A ethoxylated diacrylate is not irritating for skin. No classification is expected for skin irritation endpoint, according to the Regulation EC n°1272/2008.

Very small irritation was observed on eyes in the rabbit study, Bisphenol A ethoxylated diacrylate is not considered to be irritating for eyes. No classification is expected for eye irritation endpoint, according to the Regulation EC n°1272/2008.

No study by inhalation is available to evaluate the irritant potential of Bisphenol A ethoxylated diacrylate on the respiratory tract. But, as the substance is not skin or eye irritant, no irritation on the respiratory tract is expected. No classification is proposed.
