Description of key information
- Skin irritation: not irritating in rabbits (one study acc. to OECD guideline 404 and EU method B.4, GLP), applied to the intact skin for 4 hours. At first only one animal was used and after 4 hours exposure to the test item, very slight erythema (hardly noticeable) (grade 1) was recorded one hour after removing the patch. Full reversibility was recorded 24 hours after application.
- Eye irritation: irritating in rabbits (one study acc. to OECD guideline 405 and EU method B.5, GLP); undiluted test material applied to right eye of three animals. Moderate conjunctival redness and moderate to severe chemosis were observed in all three animals at 1 hour examination. Moderate conjunctival redness and well defined chemosis were observed in the three animals at 24 and 48 hours examination. In one animal, scattered or diffuse areas of opacity were recorded in the cornea, the details of the iris were clearly visible (grade 1) during the observation performed at one hour and up to 72 h following the administration. The cornea effects were fully reversible within 7 days. Two animals still had slight conjunctival effect on day 7 but all effects were fully reversed within 14 days.

- Executive summary:
In a primary dermal irritation study according to the OECD Guideline for the Testing of Chemicals 404 and Commission Directive 2004/73/EC Method B.4, 3 female, young adult New Zealand white rabbits were dermally exposed to 0.5 g of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters (100% a.i.) for 3 minutes, 1 and 4 hours to 6.2 cm² skin surface. Animals then were observed for 3 days.
No skin lesions were recorded after removing the patches applied for 3 minutes and 1 hour in the observation carried out 1 hour after removing the patches. After the 4 hour exposure to the test item, very slight erythema (hardly noticeable) (grade 1) was observed one hour after removing the patch. No skin lesions were observed in this animal during the observations made 24, 48 and 72 hours after removing the patches applied for 3 minutes, 1 hour or 4 hours. A semiocclusive patch with test tem was applied for 4 hours in the other two animals. No skin lesions were recorded in any of the animals during the observations made 1, 24, 48 and 72 hours after removing the patch. The means of the erythema and edema evaluations at 24, 48 and 72 hours for the three animals after a four-hour exposure were 0.00 (erythema) and 0.00 (edema).
In this study Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are not irritating to rabbit skin.

- Executive summary:
In a primary eye irritation study according to the OECD Guideline for the Testing of Chemicals 405 and Commission Directive 2004/73/EC Method B.5, 0.1 g of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters (100% a.i.) was instilled into the conjunctival sac of the right eye of three female, young adult New Zealand Whit rabbits for 1 hour. The remainder of the test item was removed with physiological saline before the first observation. Animals then were observed for 14 days.
The test item was administered initially to one animal. One hour after the application, diffuse crimson colouring (grade 2) was recorded in the conjunctiva, along with swelling with the lids more than half closed (grade 4). However, during the observations it was difficult to evaluate the hyperaemia due to the swelling of the conjunctiva. The test item was later applied to two more animals. Scattered or diffuse areas of opacity were recorded in the cornea, the details of the iris were clearly visible (grade 1) during the observation performed at one hour following the administration.
The mean values at 24, 48 and 72 hours following administration, for each type of lesion in the three treated animals were:
- Corneal opacity: 0.33
- Lesions in the iris: 0.00
- Hyperaemia: 2.22
- Edema: 0.89
In this study Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are irritating to the rabbit eye.

Additional information
Skin irritation
In a primary dermal irritation study according to the OECD Guideline for the Testing of Chemicals 404 and Commission Directive 2004/73/EC Method B.4, 3 female, young adult New Zealand white rabbits were dermally exposed to 0.5 g of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters (100% a.i.) for 3 minutes, 1 and 4 hours to 6.2 cm² skin surface. Animals then were observed for 3 days.
No skin lesions were recorded after removing the patches applied for 3 minutes and 1 hour in the observation carried out 1 hour after removing the patches. After the 4 hour exposure to the test item, very slight erythema (hardly noticeable) (grade 1) was observed one hour after removing the patch. No skin lesions were observed in this animal during the observations made 24, 48 and 72 hours after removing the patches applied for 3 minutes, 1 hour or 4 hours. A semiocclusive patch with test tem was applied for 4 hours in the other two animals. No skin lesions were recorded in any of the animals during the observations made 1, 24, 48 and 72 hours after removing the patch. The means of the erythema and edema evaluations at 24, 48 and 72 hours for the three animals after a four-hour exposure were 0.00 (erythema) and 0.00 (edema).
In this study Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are not irritating to rabbit skin.
Eye irritation
In a primary eye irritation study according to the OECD Guideline for the Testing of Chemicals 405 and Commission Directive 2004/73/EC Method B.5, 0.1 g of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters (100% a.i.) was instilled into the conjunctival sac of the right eye of three female, young adult New Zealand Whit rabbits for 1 hour. The remainder of the test item was removed with physiological saline before the first observation. Animals then were observed for 14 days.
The test item was administered initially to one animal. One hour after the application, diffuse crimson colouring (grade 2) was recorded in the conjunctiva, along with swelling with the lids more than half closed (grade 4). However, during the observations it was difficult to evaluate the hyperaemia due to the swelling of the conjunctiva. The test item was later applied to two more animals. Scattered or diffuse areas of opacity were recorded in the cornea, the details of the iris were clearly visible (grade 1) during the observation performed at one hour following the administration.
The mean values at 24, 48 and 72 hours following administration, for each type of lesion in the three treated animals were:
- Corneal opacity: 0.33
- Lesions in the iris: 0.00
- Hyperaemia: 2.22
- Edema: 0.89
In this study Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are irritating to the rabbit eye.
Respiratory irritation
No data on the respiratory irritation of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters are available.
There are no data gaps for the endpoint irritation/corrosion. No human information is available for this endpoint. However, there is no reason to believe that these results would not be applicable to humans.
Justification for selection of skin irritation / corrosion endpoint:
OECD & EC guideline study, no deviations, GLP
Justification for selection of eye irritation endpoint:
OECD & EC guideline study, no deviations, GLP
Effects on eye irritation: irritating
Justification for classification or non-classification
Skin irritation
From reliable, adequate and relevant data there is no indication on a skin irritating activity of Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters, thus the classification criteria regarding skin irritation outlined in regulation (EC) 1272/2008 or the former European directive on classification and labelling 67/548/EEC are not met.
Eye irritation
Based on reliable, adequate and relevant data, Phosphoric acid, mono- and di- C16-18 (even numbered) alkyl esters have to be classified as irritating to eyes (Category 2) according to CLP, EU GHS (Regulation (EC) No 1272/2008) and is assigned the hazard statement H 319 and the signal word “Warning”. According to the criteria set out in directive 2011/59/EC, Annex VI, Phosphoric acid, mono- and di-C16-18-alkyl esters are considered to be non irritant to the eyes and no risk phrase is required.
