(3-aminophenyl)uronium chloride

Endpoint summary

Description of key information

Skin Irritation
The primary irritation index on rabbit for (3-aminophenyl)uronium chloride is estimated to be 1.91. Based on this value, it can be estimated that(3-aminophenyl)uronium chloride exhibits slight irritation potential to rabbit  skin. However, the PDII score is not considered high enough for classification of the chemical as a skin irritant. Thus, the chemical (3-aminophenyl)uronium chloride is not considered to be a skin irritant.
Eye Irritation
(3-aminophenyl)uronium chloride is irritating to rabbit eye at 100 mg/24H concentration.

Principles of method if other than guideline:

The Draize Test is an acute toxicity test devised in 1944 by Food and Drug Administration (FDA) toxicologists John H. Draize and Jacob M. Spines. Initially used for testing cosmetics, the procedure involves applying 0.5mL or 0.5g of a test substance to the eye or skin of a restrained, conscious animal, and then leaving it for set amount of time before rinsing it out and recording its effects. The animals are observed for up to 14 days for signs of erythema and edema in the skin test, and redness, swelling, discharge, ulceration, hemorrhaging, cloudiness, or blindness in the tested eye. The test subject is commonly an albino rabbit, though other species are used too, including dogs. The animals are euthanized after testing if the test renders irreversible damage to the eye or skin. Animals may be re-used for testing purposes if the product tested causes no permanent damage. Animals are typically reused after a "wash out" period during which all traces of the tested product are allowed to disperse from the test site.
