An acute skin irritation study of the test item Vantex T was performed in New Zealand White rabbits. Parameters monitored during this study included mortality, body weight measurements and clinical observations. The irritation effects of the test item were evaluated according to the Draize method (OECD No.: 404, 2002).
The test item was administered undiluted, at a single dose of 0.5 ml. Gauze was placed onto the hairless skin of the rabbit, test item was applied to the gauze, additional gauze was placed over the test item and an adhesive clear plastic patch applied. The trunk was wrapped in clear plastic with medical tubing used to hold the patch in place. The untreated skin of each animal served as control.
After 4 hours, the remaining test item was removed with water of body temperature.
To assess skin irritation, animals were examined at 1, 24, 48 and 72 hours after the patch removal. Additional general examinations were performed daily.
There was no mortality or systemic clinical changes related to Vantex T administration.
There was no effect of treatment on body weight.
At observation one hour after patch removal, well defined erythema (score 2) was observed in one animal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 24 hours after patch removal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 48 and 72 hours after patch removal, there were no observed signs on the skin of the treated animals.

Additional information
Skin irritation
A study was conducted to assess skin irritation potential of Butyldiethanolamine in Vienna White rabbits (OECD 404; BASF, 1967, Report No. XVII/49). Two animals (1 male / 1 female) were treated for 1, 5, 15 minutes and for 20 hours using occlusive conditions. The test item was applied unchanged on the dorsal skin of each rabbit by means of a test patch. An application site of 2.5 x 2.5 cm was covered with the liquid test substance and maintained in place over the exposure period. The untreated skin area of the test animals served for control. In addition, the test item also was applied onto the ear for 20 hours. The results from the ear, however, would not be taken into account for evaluation as they do not represent testing of the dorsal/lateral flank of the back. After the application time, the skin was washed with water which sometimes contained a mild detergent (1, 5 and 15 minutes). Following the 20 hour application, the skin was not washed after removal of the dressing. The animals were observed for 8 days. Skin reaction was recorded after 1, 24, 48, 72, 96 h and after 7 and 8 days after patch removal. The evaluation of the skin findings was performed according to the Draize Scoring System. Only the scorings referring to the 20 hour treatment of the skin were considered for assessment.
At the end of the observation period of 8 days, the 20 h-treated skin of both animals displayed severe necrosis (in one case: leathery aspect) and scaling. Taking into account the 20 h duration of treatment, the findings give evidence for the test item to be corrosive to the skin of rabbit. This is further supported by the results of the short term applications (1, 5, 15 minutes). Regarding the first animal, after application for 1 or 5 minutes, respectively, questionable redness (grade 1) was reported; this however was no more seen after 24 hours. After the 15 minutes treatment, questionable redness (grade 1) was seen until reading time point 48 h, and became more defined after 72 h (grade 2); scaling was still seen at the end of the observation period of 8 days. Regarding the second animal, treatment for 1 and 5 minutes resulted in questionable redness (grade 1) lasting until reading time point 72 h. Treatment for 15 minutes resulted in questionable to well defined redness (grade 1 - 2), accompanied by crusting, present until day 7 of observation.
Regarding the ear which was treated for 20 hours, redness of grade 1 and 3 was reported for the first and second animal, respectively. No further skin reaction was seen until the end of the observation period of 8 days.
The skin reactions gave evidence for the test item to be corrosive to rabbit skin under the test conditions used.
Butyldiethanolamine was tested in a second acute skin irritation study in New Zealand White rabbits (LAB Research Ltd., 2009, Report No. 09/189 -006N). Parameters monitored during this study included mortality, body weight measurements and clinical observations. The irritation effects of the test item were evaluated according to the Draize method (OECD No.: 404, 2002). The test item was administered undiluted, at a single dose of 0.5 mL under semi-occlusive conditions. The untreated skin of each animal served as control. After 4-hour exposure period, the remaining test item was removed with water of body temperature. The animals were examined at 1, 24, 48 and 72 hours after the patch removal for skin irritation responses. Additional general examinations were performed daily. There was no mortality or systemic clinical changes related to the test material administration. There was no effect of treatment on body weight.
At observation one hour after patch removal, well defined erythema (score 2) was observed in one animal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 24 hours after patch removal, very slight erythema (score 1) was found in one animal and very slight oedema (score 1) was found in two animals.
At 48 and 72 hours after patch removal, there were no observed signs on the skin of the treated animals.
As no clinical signs were observed up to 72 hours after patch removal, the study was terminated after the 72 hour observation.
The animals' individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for erythema were 0.00, 0.00 and 0.33 respectively.
The animals' individual mean scores (considering readings at 24, 48 and 72 hours after patch removal) for oedema were 0.33, 0.33 and 0.00 respectively.
In conclusion, Butyldiethanolamine does not meet the criteria for classification as irritant or corrosive according to EU classification and labelling Regulations since all scores were under the cut-off value of 2.3. No symbol and risk phrase are required. The corrosive result from the BASF-study is more than worst case. A 20-h exposure time from this study cannot be evaluated comparing to 4 -hour exposure in the more recent OECD guideline conform study (LAB Research Ltd., 2009). Moreover, the exposure was under occlusive conditions in the BASF study while semi-occlusive conditions were in the LAB Research Ltd. study. Therefore, the BASF study results can be disregarded.
Eye irritation
Butyldiethanolamine was tested for eye irritation in the rabbit according to an internal BASF method (BASF, 1967; Report No. XVII/49), which in principle was similar to the OECD TG 405 (1981). Approximately 50 µL of the unchanged test material were applied into the conjunctival sac of one eye of each of 2 rabbits. The saline-treated eye served as control. The animals were observed several times on the treatment day and up to 8 days afterwards, and findings were recorded on working days. The eyes were not washed out after 24 h as specified in OECD Guideline 405. The findings were evaluated according to the Draize Scoring System.
The instillation of the test material into the eye of rabbit resulted in severe irreversible lesions.
Justification for selection of skin irritation / corrosion endpoint:
GLP guideline study properly conducted: exposure time 4 hours under semi-occlusive conditions.
Justification for selection of eye irritation endpoint:
One study available
Effects on eye irritation: corrosive
Justification for classification or non-classification
Skin irritation
According to the classification criteria outlined in the section 3.2.2.2. (Guidance on the Application of CLP criteria, 2013), if the mean value of≥2.3 -≤4.0 was reached for erythema/eschar or for oedema in at least 2 of 3 tested animals from gradings at 24, 48 and 72 hours after patch removal, the classification as Skin Irritant would be assigned. The highest value for erythema/eschar and oedema was 1.0 in each of three animals at 24 -h, 48 -h or 72 -h reading points (LAB Research Ltd., 2009). The mean values of 0.00, 0.00 and 0.33 for erythema and 0.33, 0.33 and 0.00 for oedema were measured in animal 1, 2 and 3, respectively. Therefore, Butyldiethanolamine does not meet criteria under Regulation (EC) No 1272/2008 for classification and labelling as a skin irritant.
Eye irritation
Butyldiethanolamine caused irreversible damage to the eyes of rabbits. Therefore, the substance should be classified and labelled as seriously damaging to eyes (Category 1, H318) according to Regulation (EC) No 1272/2008.
