Description of key information
In the key skin irritation study conducted with the nearest analogue Fe(3K)EDDHSA (EC No. 462 -490 -6) the average scores calculated for each of the three animals for three consecutive days (24, 48 and 72 hours) do not exceed cut-off-values defined in the CLP. Application of the other closely related substance Fe(Na)EDDHA (CAS 84539-55-9) to the rabbit skin was evaluated as not irritating in two skin irritation studies in albino rabbits.
In the key eye irritation study conducted with Fe(3K)EDDHSA the mean values of the scores calculated for each animal over 24, 48 and 72 hours were 0.7, 0.3 and 0.0 for chemosis, 0.0, 0.0 and 0.0 for redness of the conjunctiva, 0.0, 0.0 and 0.0 for iris lesions and 0.0, 0.0 and 0.0 for corneal opacity. The values did not exceed the trigger values leading to classification and labelling according to CLP. Two eye irritation studies, performed according to OECD Guideline 405 with the test item Fe(Na)EDDHA (CAS 84539-55-9) in rabbits, showed that the test substance does not cause eye irritation as none of the animals achieved a mean score leading to classification according to CLP.

- Executive summary:
The potential of the test substance Fe3KEDDHSA to induce skin irritation was evaluated in rabbits according to OECD (No. 404, 17th July 1992) and EC (92/69/EEC, B.4, 31st July 1992) guidelines. The test substance was applied for periods of 3 minutes and 4 hours to a single male New Zealand White rabbit. Since the test substance was not irritant on this first animal, it was then applied for 4 hours to two other animals. A single dose of 500 mg of the test substance in its original form was applied to the closely-clipped skin of one flank. The test substance was held in contact with the skin by means of a semi-occlusive dressing. Cutaneous reactions were observed approximately 1 hour, 24, 48 and 72 hours after removal of the dressing. The mean values of the scores for erythema and oedema were calculated for each animal. After a 3-minute exposure no cutaneous reactions were observed in the first animal. A brown coloration of the skin, which could have masked a possible very slight erythema, was noted at the 1-hour scoring only. After a 4-hour exposure no cutaneous reactions were observed in 1/3 animals; a brown coloration of the skin, which could have masked a possible very slight erythema, was noted at the 1 -hour scoring only. In both remaining animals, a very slight or well-defined erythema was noted from day 1 up to day 3. Mean scores over 24, 48 and 72 hours for each animal were 0.0, 1.0 and 1.0 for erythema and 0.0, 0.0 and 0.0 for oedema. Under the experimental conditions, the test substance Fe3KEDDHSA is slightly irritant when applied topically to rabbits.

Skin irritation
The potential of the test substance Fe(3K)EDDHSA (EC No. 462-490-6) to induce skin irritation was evaluated in rabbits according to OECD Guideline 404 (Centre Internationale de Toxicologie, 2000c, Report No. 20503 TAL). The test substance was applied for periods of 3 minutes and 4 hours to a single male New Zealand White rabbit. Since the test substance was not irritant to the first animal, it was then applied for 4 hours to two other animals. A single dose of 500 mg of the test substance in its original form was applied to the closely-clipped skin of one flank. The test substance was held in contact with the skin by means of a semi-occlusive dressing. Cutaneous reactions were observed approximately 1 hour, 24, 48 and 72 hours after removal of the dressing. The mean values of the scores for erythema and oedema were calculated for each animal. After a 3-minute exposure no cutaneous reactions were observed in the first animal. A brown coloration of the skin, which could have masked a possible very slight erythema, was noted at the 1-hour scoring only. After a 4-hour exposure no cutaneous reactions were observed in 1/3 animals; a brown coloration of the skin, which could have masked a possible very slight erythema, was noted at the 1 -hour scoring only. In both remaining animals, a very slight or well-defined erythema was noted from day 1 up to day 3. Mean scores over 24, 48 and 72 hours for each animal were 0.0, 1.0 and 1.0 for erythema and 0.0, 0.0 and 0.0 for oedema. Under the experimental conditions, the test substance Fe(3K)EDDHSA is slightly irritant when applied topically to rabbits.
Two acute skin irritation/corrosion studies in albino rabbits were performed to determine the irritant or corrosive potency of the test substance Fe(Na)EDDHA (CAS 84539-55-9) on the albino rat skin (CIBA-GEIGY, 1993c, Report No. 931143; Mercier, 1992, Report No. 209306).These tests were based on the OECD Guideline 404 (Acute Dermal Irritation/Corrosion) and were performed on 3 rabbits, checked for normal skin conditions. A gauze patch bearing 0.5 g of the test article was applied to the right flank of each animal and held in place for 4 hours by an adhesive tape. The studies showed that Fe(Na)EDDHA does not cause skin irritation, as the mean values of the recordings 24 to 72 hours after application were scored 0 in the study performed by CIBA-GEIGY (1993) and the scores determined in the study of Mercier (1992) were all below the trigger values for classification as skin irritant.
Eye irritation
The potential of the test substance Fe(3K)EDDHSA (EC No. 462-490-6) to induce ocular irritation was evaluated in New Zealand White rabbits according to OECD Guideline 405 (Centre Internationale de Toxicologie, 2000d, Report No. 20504 TAL). A single dose of 100 mg of the test substance in its original form was introduced into the left conjunctival sac of three animals. The right eye was not treated and served as control. Ocular reactions were observed approximately 1 hour, 24, 48 and 72 hours after the administration. The mean values of the scores for chemosis, redness of the conjunctiva, iris lesions and corneal opacity were calculated for each animal. The interpretation of results was carried out according to the classification criteria laid down in the Regulation (EC) No. 1272/2008 (CLP).
Slight conjunctival reactions (very slight or slight chemosis, very slight redness of the conjunctiva and clear discharge) were observed in all animals on day 1 (day of application). A very slight chemosis persisted in 2/3 animals on day 2 (24 -hour reading) and in 1/3 animals on day 3 (48 -hour reading). No lesions were observed on day 3 (72 -hour reading). No other ocular reactions were noted during the study. Mean scores calculated for each animal over 24, 48 and 72 hours were 0.7, 0.3 and 0.0 for chemosis, 0.0, 0.0 and 0.0 for redness of the conjunctiva, 0.0, 0.0 and 0.0 for iris lesions and 0.0, 0.0 and 0.0 for corneal opacity. The mean scores for 2 out of 3 animals do not exceed trigger values for classification and labelling defined in the CLP. The test substance Fe(3K)EDDHSA is considered to be not irritating to eyes.
Two eye irritation studies were performed according to OECD Guideline 405 (Acute Eye Irritation/Corrosion) with the test item Fe(Na)EDDHA (CAS 84539-55-9) (CIBA-GEIGY, 1993d; Report No. 931144; Mercier, 1992, Report No. 209305). The tests were performed on 3 New Zealand White rabbits. A volume of 0.1 mL of the test item was placed into the conjunctival sac of the left eye of each animal. The lids were then held together for about one second in order to prevent loss of the test article. The animals were checked daily for systemic symptoms and mortality. The studies showed that the test substance does not cause eye irritation as none of the animals achieved a mean score leading to classification according to GHS (>= 1 for cornea and iris; >= 2 for redness and chemosis).
Justification for selection of skin irritation / corrosion endpoint:
Key study conducted with the nearest analogue Fe(3K)EDDHSA (EC 462-490-6)
Justification for selection of eye irritation endpoint:
Key study conducted with the nearest analogue Fe(3K)EDDHSA (EC 462-490-6)
Effects on skin irritation/corrosion: slightly irritating
Justification for classification or non-classification
Based on the results of skin and eye irritation studies available for the structurally related substances Fe(3K)EDDHSA (EC No. 462 -490 -6) and Fe(Na)EDDHA (CAS 84539 -55 -9) the target substance Fe(3Na)EDDHSA is considered to be not irritating to skin and eyes and does need to be classified and labelled as an eye or skin irritant according to Regulation 1272/2008/EC (CLP).
