It was classified in Category 3 which is the higher hazard between two LD50 values for rats (304.5 mg/kg (EPA RED (2006)) and 240 mg/kg (PIM G022 (1999), corresponding to List 1)), one of which corresponds to Category 3 and another corresponds to Category 4.

On the basis of an LC50 value of 53 mg/m3/4h = 0.053 mg/L/4h for rats (HSDB (2010)), it was classified in Category 2.
Besides, a reference value of dust/mist was applied from the description of exposure to "aerosol" (HSDB (2010)).
2 Skin corrosion/irritation Category 1

It was classified in Category 1 from a "corrosive" result in a test using rabbits (EPA RED (2006)) and the information that necrosis was observed at concentrations of 1% or higher in tests applied aqueous solutions to rabbits and guinea pigs (HSDB (2010)).
3 Serious eye damage/eye irritation Category 1

Danger
H318
P305+P351+P338
P280
P310
In a test applied 0.1 mL of 10% solution of this substance into the conjunctival sac of three rabbits (OECD TG 405; GLP), severe damage in the cornea, iris, and conjunctiva occurred in all animals, the severe damage in the cornea and iris lasted until the end of a 21-day observation period, and MMAS (irritation score: equivalent to AOI) was 108 (maximum 110) (ECETOC 48 (1998)).
Therefore, it was classified in Category 1.
4 Respiratory sensitization Classification not possible - - - No data.
4 Skin sensitization Category 1

P302+P352
P333+P313
P261
P272

P321
P363
P501
It was reported that two physicians were sensitized to this substance from handling instruments soaked in a disinfectant containing this substance and developed allergic conjunctivitis from eye drops containing this substance. (PIM G022 (1999))
This substance is the acknowledged cause of allergic contact dermatitis, and it is also reported that all six patients who had a history of using a skin emollient containing this substance and presented with flexural eczema, were identified as a type 4 allergy in a patch test. (HSDB (2010))
Furthermore, this substance is listed as a sensitizing substance in "Contact Dermatitis (Frosch) (4th, 2006)" (corresponding to List 1).
Therefore it was classified in Category 1.
5 Germ cell mutagenicity Not classified - - - From a negative result in a micronucleus test using mice (in vivo mutagenicity test) (EPA RED (2006)) (EMEA (1997), corresponding to List 2), it was classified as "Not classified."
Besides, as in vitro tests, a negative in an Ames test (NTP DB (1984); EPA RED (2006)) and a positive in a micronucleus test using human lymphocytes (HSDB (2010)) were reported.
6 Carcinogenicity Not classified - - - In a diet administrated carcinogenicity test in rats and mice, evidence of carcinogenicity was not found in either animal species. (EPA RED (2006))
And it is concluded that this substance, for which the database for carcinogenicity is complete, is not carcinogenic based on studies in rats and mice. (EPA RED (2006))
Therefore, it was classified as "Not classified."
Besides, it was reported that no evidence of carcinogenicity was obtained in a diet administration test in rats for two years or in guinea pigs for one year (EMEA (1997)) and no tumors were observed in dermal administration in mice and rabbits for 80 weeks. (HSDB (2010))
7 Reproductive toxicity Category 2

Warning
H361
P308+P313
P201
P202
P281
P405
P501
In a developmental toxicity test in which mice were orally administrated from day 0 to 6 of gestation, significant and dose-dependent decreases in a pregnancy rate, an implantation number, and a fetus number at 3 mg/kg bw/day or higher were shown. (EMEA (1997))
But it was classified in Category 2 due to no description of general toxicity in maternal animals.
Besides, in vaginal administration on day 1 of gestation in rats, a statistically significant and dose-dependent decrease in mean fetus numbers in addition to a decrease in maternal body weights at 100 mg/kg or higher was observed.
Furthermore, a significant decrease in implantation numbers in the highest dose group (200 mg/kg) was indicated. (HSDB (2010))
But adverse effects on sexual function and fertility were not reported in a two-generation diet administration test in rats. (USEPA/HPV (2001))
8 Specific target organ toxicity - Single exposure Category 2 (lung)

Warning
H371
P309+P311
P260
P264
P270
P405
P501
Rats showed increased lung weights, severe inflammations and irritations in the lung after inhalation exposure to 0.03 mg/L (mists) for 6 hours (converted to a 4-hour equivalent value: 0.045 mg/L) (HSDB (2010)).
It corresponds to Category 1 by judging from Guidance values, but it was classified in Category 2 (lung) in accordance with Guidance because data are from List 2 and do not meet Decision Criteria 1b3) (an OECD TG test that is according to GLP and has some degree of approval).
Besides, it was reported that both of two-and-a-half-month-old twins mistakenly and orally ingested an 11% solution of this substance developed fever, dehydration, cough, salivation, and numerous oral and pharyngeal lesions within 24 hours and recovered by treatments, though one of them developed chemical pneumonia. (PIM G022 (1999))
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - In a 12-week repeated oral administration test in rats, deaths of two animals and a decrease in weight gain around the upper limit of a range in Guidance values (100 mg/kg/day) were observed but adverse effects on changes in other test parameters including pathological tests were not reported. (HSDB (2010))
Due to this data from a test in males only and no description of a cause of deaths, the classification is not possible.
Besides, in a 52-week oral administration test in dogs dosed at 12.5 to 50 mg/kg/day, systemic effects were not observed except for those in the digestive tracts such as hyperemia and inflammations of the stomach and small intestine as local effects. (HSDB (2010))
But it cannot be a basis for the classification (as "Not classified") because doses are within a range of Guidance values.
On the other hand, in a 3-month dermal administration test in rats at 10 mg/kg/day, changes in blood cell parameters and damage in liver and kidney were mentioned (EMEA (1997)), but more details are not described and unknown.
Furthermore, in a 14-week inhalation exposure test to rats at 0.0099 mg/L, it was reported that effects were not observed (HSDB (2010)), but it cannot be used as a basis for the classification (as "Not classified") because the concentration is within a range of Guidance values.
From the above, it was classified as "Classification not possible" due to lack of data in each oral, dermal and inhalation route.
10 Aspiration hazard Classification not possible - - - No data.
