Description of key information
Exposure of intact rabbit skin to 2-butoxyethyl methacrylate for a 4-hour period produced slight-moderate erythma on 2/3 animal but no abnormal body weight changes, toxic symptoms / mortality, or skin discolouration. A primary skin irritation index of 0.7 was calculated for 2-butoxyethyl methacrylate. Although the erythema scores were below the threshold for classification, due to the irreversibility of the effects in two animals (desquamation after 7 days) the substance should be classified as a skin irritant category 2 in accordance with CLP Regulation.
When applied to the eye mucosa of rabbits at 0.1 ml, 2-butoxyethyl methacrylate was found not to produce a significantly irritating reaction, with minimal or no irritating, corrosive, and/or discoloration effects observed for the cornea, iris, or conjunctivae at 24, 48, and 72 hours post-administration. No toxic effects / mortality was exhibited by the test animals. A primary eye irritation index of 0.6 was calculated for 2-butoxyethyl methacrylate and it was determined that classification as a potential eye irritant was not required (CLP Regulation (EC) No. 1272/2008).

- Irritant / corrosive response data:
- 2-Butoxyethyl methacrylate showed a primary skin irritation score of 0.7 when applied to intact rabbit skin. In two animals slight - severe desquamation was observed after 7 days.
- Other effects:
- No discolouration of the skin was observed that could be related to effects of the test material and the body weight gain of all rabbits was similar. No acute toxic symptoms or mortality occurred during the 7-day test period. Due to the results obtained, no macroscopic organ examination was carried out.
- Interpretation of results:
- Category 2 (irritant) based on GHS criteria
- Conclusions:
- In a 7-day primary skin irritation study, 4-hour exposure of 2-butoxyethyl methacrylate to intact rabbit skin resulted in an irritation score of 0.7. The the mean grading value for erythema and for edema at 24, 48, and 72 hours was <1.5 (GHS 2011). However, two animals showed signs of desquamation at the end of the testing period (day 7) indicating the substance should be classified as a skin irritant in accordance with GHS.
- Executive summary:
A GLP-compliant primary skin irritation study was carried out for 2-butoxyethyl methacrylate using white New Zealand rabbits of mixed sex. The experiment was performed in line with OECD Guideline 404 (Acute Dermal Irritation / Corrosion) and Council Directive 79/831/EEC. Annex V, Part B. Methods for the Determination of Toxicity; 4.1.5. Acute Toxicity, 'Skin Irritation'. The aim of the study was to establish the irritation potential of 2-butoxyethyl methacrylate to provide a rational basis for risk assessment in humans given that skin contact is a probable route for exposure.
A single 0.5 ml dose of the undiluted substance was applied to an area (10 cm x 10 cm) of shaved rabbit skin following a 4-day acclimation period. The skin was covered with a patch (3.0 cm x 3.0 cm) of surgical gauze that was protected with aluminium foil and an occlusive dressing. After a 4-hour exposure period the dressing was removed, and the skin was flushed with lukewarm tap water. Viability / mortality, corrosive properties of the test article, and skin colour were monitored at 1, 24, 48, and 72 hours and on day 7. Body weight was recorded pre-test and on day 1 and 7. Evaluation of the skin reaction entailed allocating a numerical irritation score to visible erythema and eschar formation and to edema formation in order to grade lesion severity.
No discolouration of the skin was noted that could be related to the test article, although in two rabbits desquamation was observed on day 7. The body weight gain of all rabbits was similar, and no acute toxic symptoms were observed during the test period. Necropsy was not performed due to the results obtained. Totalling the individual cumulative irritation scores and dividing by the number of figures for 1, 24, 48, and 72 hours gave a primary irritation index of 0.7 for 2-butoxyethyl methacrylate. According to the criteria specified in GHS (2011), the registered substance should be classified as irritant to the skin as two if the animals showed signs of inflammation (desquamation) at the end of the test period.

SCORING SYSTEM:
Irritation was assessed according to the OECD Guidelines for testing of chemicals, Section 4, No. 405 "Acute eye Irritation / Corrosion" - Adopted May 12, 1981. The corrosive properties of the test article and the colour of the treated eye were described and recorded. The following subjective numerical scoring system was used to grade any eye lesions:
Corneal Irritation
Opacity - degree of density (densest area used for assessment)
- No ulceration or opacity: 0; Scattered or diffuse areas of opacity (other than slight dulling of normal luster), details of iris clearly visible: 1*; Easily discernible translucent area, details of iris slightly obscured: 2*; Nacrous area, no details of iris visible, size of pupil barely discernible: 3*; Opaque cornea, iris not discernible through the opacity: 4*
Iridic Irritation
- Normal: 0; Markedly deepened rugae, congestion, swelling, moderate circumcorneal hyperemia, or injection, any of these or combination thereof, iris still reacting to light (sluggish reaction is positive): 1*; No reaction to light, haemorrhage, gross destruction (any or all of these): 2*
Conjunctival Irritation
Redness (refers to palpebral and bulbar conjunctivae, cornea and iris)
- Blood vessels normal: 0; Some blood vessels definitely hyperemic (injected): 1; Diffuse, crimson colour, individual vessels not easily discernible: 2*; Diffuse beefy red: 3*
Chemosis: lids and/or nictating membranes
- No swelling: 0; Any swelling above normal (includes nictating membranes): 1; Obvious swelling with partial eversion of lids: 2*; Swelling with lids about half closed: 3*; Swelling with lids more than half closed: 4*
Maximum cumulative score: 13
*Starred figures indicate positive effect

- Irritant / corrosive response data:
- 2-Butoxyethyl methacrylate had a primary irritation score of 0.6 when applied to the rabbit eye mucosa. 1-hour post-administration all animals exhibited symptoms of edema and redness in the conjunctivae, reddened vessels in the sclera, and moderate discharge from the right eye. A reddened conjunctival sac (hardly visible) was observed in one animal after 24 hours, however, past this time point no abnormal changes were visible. No abnormal symptoms were evident in the other two rabbits after 24, 48, and 72 hours. No corrosion of the cornea occurred.
- Other effects:
- No acute toxic symptoms or mortality was observed in any animal during the test period and the body weight gain of all rabbits was similar. Due to the results obtained no macroscopic organ examination was indicated.
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- A primary eye irritation study that involved a single application of 0.1 ml 2-butoxyethyl methacrylate to the left conjunctival eye sacs of three New Zealand rabbits reported a final primary irritation index of 0.6. 2-Butoxyethyl methacrylate did not result in a significantly positive mean grading response with regards to corneal opacity, iritis, conjunctival redness, and/or conjunctival oedema (chemosis) to warrant classification as irritating to the eyes (Category 2) (CLP Regulation (EC) No. 1272/2008).
- Executive summary:
To determine the eye irritation potential of 2-butoxyethyl methacrylate, an in vivo experiment was undertaken with New Zealand rabbits of mixed sex that complied with Good Laboratory Practise (GLP). The procedure outlined in the report followed OECD Guideline 405 (Acute Eye Irritation / Corrosion) and Council Directive 79/831/EEC. Annex V, Part B. Methods for the Determination of Toxicity; 4.1.6. Acute Toxicity, 'Eye Irritation'. The aim of the report was to deliver a rational basis for human risk assessment.
A single application of 0.1 2-butoxyethyl methacrylate in undiluted form was administered to the left conjunctival eye sac of three rabbits, which were subsequently left unwashed for the experiment duration. The right eye remained untreated and was used as a reference control. Viability / mortality, corrosive properties of the test article, and eye colouration were monitored and recorded daily, and body weight was recorded pre-test and on day 1 and 7. The eyes were examined for signs of irritation at 1, 24, 48, and 72 hours post-administration. Evaluation of irritation reaction and lesion severity was based on a numerical scoring system the graded corneal irritation (opacity), iridic irritation, and conjunctival irritation (redness and chemosis). The study was terminated 72 hours after article application and all rabbits were killed by intravenous injection of T61.
2-butoxyethyl methacrylate was calculated to produce a primary eye irritation index of 0.6. Conjunctivae redness (hardly visible) was observed in one animal after 24 hours but this was determined not to be related to the substance. The effect was not evident after this point and no additional abnormal change was visible in other animals. The test material did not generate corrosive or toxic symptoms / mortality during the study and due to the overall results obtained, no macroscopic organ examination was indicated. As 2-butoxyethyl methacrylate did not induce a significantly positive response with respect of corneal opacity, iritis, conjunctival redness and/or conjunctival oedema (chemosis) (GHS 2011), the registered substance is concluded not to be an eye irritant. Subsequently, 2-butoxyethyl methacrylate does not require classification according to CLP Regulation (EC) No. 1272/2008.
