Conclusions:
Under test conditions the target substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester can be considered non irritant.
Executive summary:

The test was performed by means of a single dose application of the target substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester on the skin of 6 albino male rabbits. The test material was applied to the shaved skin of 6 rabbits at a dose of 500 mg/rabbit for 4 hours. The animals were observed after the removal of the bandages and after 24, 48 and 72 hours for signs of erythema or oedema. During the study in all treated animals no erythema and edema was observed. Under test conditions the test material can be considered non irritant.

Executive summary:

The test was performed by means of a single dose application of the target substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester on the skin of 38 volunteers (15 males, 23 females, aged between 18 and 65 years). Each volunteer served as its own control, having a treated and a non-treated area of skin. The test material was applied at doses of 0.5 ml in an area of about 1 cm² on the back by means of an occlusive patch. The patches were removed 48 hours after application and reactions evaluated 15 minutes and again 24 hours following the removal of patches. Skin irritation was scored according to Draize. No skin irritation (Erythema = 0, Edema = 0) was found in any of the volunteers and 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester was judged to be non-irritant.

Interpretation of results:
GHS criteria not met
Conclusions:
The test material was not an eye irritant.
Executive summary:

An ocular irritation test was carried out on test material Cosmacol ECI according to OECD Guideline 405.

The test was performed by placing the test material in a single dose in the conjunctival sac of 6 albino male rabbits at a dose of 0.1 mL/animal. The animals eyes were examined 1, 24, 48 and 72 hours after the beginning of the test. The ocular areas obvserved were the cornea, the iris and conjunctivae. The results showed a slight congestion of the conjunctivae in all 6 rabbits 1 h and in 2 of 6 animals 24, 48, 72 h

after the treatment. After 7 days it disappeared.

It was concluded that the read-across substance Cosmacol ECI is to be considered non-irritant to eyes.

Additional information

A skin irritation test according to OECD 404 was performed by means of a single dose application of the target substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester on the skin of 6 albino male rabbits. The test material was applied to the shaved skin of 6 rabbits at a dose of 500 mg/rabbit for 4 hours. The animals were observed after the removal of the bandages and after 24, 48 and 72 hours for signs of erythema or oedema. During the study in all treated animals no erythema and edema was observed. Under test conditions the test material can be considered non irritant.

The target substance was also tested in a human patch test. The results of the study interpreted in accordance with Draize Method, indicate that the test material can be considered as non-irritant. Also tests on the Source substance Tri(hexyl, octyl, decyl) citrate and the structurally related 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C14 -15 -alkyl) ester showed no irritant effect.

An ocular irritation test was carried out on target substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester according to OECD Guideline 405. The test was performed by placing the test material in a single dose in the conjunctival sac of 6 albino male rabbits at a dose of 0.1 mL/animal. The animal's eyes were examined 1, 24, 48 and 72 hours after the beginning of the test. The ocular areas observed were the cornea, the iris and conjunctivae. The results showed a slight congestion of the conjunctivae in all 6 rabbits 1 h and in 2 of 6 animals 24, 48, 72 h after the treatment. After 7 days it disappeared. It was concluded that the target substance is to be considered non-irritant to eyes. Also no reactions were detected in a CAM study with the similar substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C14 -15 -alkyl) ester: thus the test material showed no irritant effect in vitro, and would be predicted to be non-irritant in vivo. In studies according OECD 405 with the Source substance Tri (hexyl, octyl, decyl) citrate and the similar substance 1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C14 -15 -alkyl) ester were also not seen eye irritation. It was concluded that the target substance is to be considered non-irritant to eyes.

The available information demonstrates no irritating effects on skin nor in eyes of rabbits.

Justification for classification or non-classification

The available information demonstrates no irritating effects on skin nor in eyes of rabbits of the target substance

1,2,3 -Propanetricarboxylic acid, 2 -hydroxy-, tris(C12 -13 -branched-alkyl) ester.

No classification for skin or eye irritation is indicated according to the classification, labeling and packaging (CLP) regulation (EC) No 1272/2008.
