Description of key information
The test item was tested for its skin irritant properties in 3 New Zealand White rabbits. The study was performed according to OECD Guideline 404. The only deviation was that the test item was applied as 77% paste in water, but since according to the guideline dry powders have to be moistened, the testing conditions and results are considered to be the same. Effects on the skin (erythema grades up to 4 and edema scores up to 3) were observed in all animals 24 hours after application. These signs were reversible within the 21 days observation period.
The test item was tested for its eye irritant properties in 3 New Zealand White rabbits.The study was performed according to OECD Guideline 405. The only deviation was that the test item was applied as 77% paste in water, but since the dry powder is moistened when it comes in contact with the eye, the testing conditions and results are considered to be the same.
Effects on conjunctivae (redness and swelling), iris and cornea were observed in all animals one hour after application. These signs were irrevesible in 2 of 3 animals.

Additional information
Skin irritation: 1 key study and 1 abstract available: irritating
Eye irritation: 1 key study and 1 abstract available: corrosive
There are one reliable study and one abstract available on the skin irritancy potential. Phosphoric acid, dodecyl ester, potassium salt was tested for its skin irritant properties in 3 New Zealand White and 6 Albino Russian rabbits. The studies were performed according to OECD Guideline 404. Deviations were the application as 77% paste (key study) and a prolonged exposure period (24 hours; supporting study). Effects on the skin (erythema grades up to 4 and edema scores up to 3) were observed in all animals 24 hours after application.These signs were reversible within the 21 days observation period.
