Rationale for the classification
1 Acute toxicity (Oral) Category 4


Warning
H302 P301+P312
P264
P270
P330
P501
It was classified in Category 4 based on an LD50 value of 570 mg/kg for rats (PATTY (5th, 2001)).

As for health hazards, also refer to o-chlorophenol (CAS 95-57-8) and p-chlorophenol (CAS 106-48-9), the isomers.
1 Acute toxicity (Dermal) Classification not possible
-
-
- - No data available.
1 Acute toxicity (Inhalation: Gases) Not applicable
-
-
- - Solid (GHS definition)
1 Acute toxicity (Inhalation: Vapours) Classification not possible
-
-
- - No data available.
1 Acute toxicity (Inhalation: Dusts and mists) Classification not possible
-
-
- - No data available.
2 Skin corrosion/irritation Classification not possible
-
-
- - Besides, it is reported for o-chlorophenol and p-chlorophenol, the isomers, that corrosion was observed in a skin irritation test with rabbits (ATSDR (1999)).
3 Serious eye damage/eye irritation Category 2


Warning
H319 P305+P351+P338
P337+P313
P264
P280
An application of 0.15 mL of a 1% aqueous solution of this substance to the rabbit eye caused slight hyperemia, after an application of 0.15 mL of a 2% aqueous solution, moderate to severe hyperemia, mild to moderate edema, cloudy cornea, and exudation were observed, and these changes became evident 5 minutes after the application, were most intense after 5 hours, and subsided after 96 hours (HSDB (2009)). It was classified in Category 2 based on the above results, but the subcategorization of Category 2A or 2B was impossible because the test substance was diluted (1% or 2%).
4 Respiratory sensitization Classification not possible
-
-
- - No data available.
4 Skin sensitization Classification not possible
-
-
- - No data available.
5 Germ cell mutagenicity Classification not possible
-
-
- - The classification is not possible due to no in vivo test data. Besides, in vitro tests, there is a report on a negative result in an Ames test (NTP DB (1979)).
6 Carcinogenicity Classification not possible
-
-
- - No data available.
7 Reproductive toxicity Classification not possible
-
-
- - No data available. Besides, it is reported for o-chlorophenol, the isomer, that a decrease in litter size and an increase in the number of stillbirths were observed in a drinking water administration test with rats (Environmental Risk Assessment for Chemical Substances (Ministry of the Environment, 2008)).
8 Specific target organ toxicity - Single exposure Category 2 (nervous system)


Warning
H371 P308+P311
P260
P264
P270
P405
P501
In an acute oral toxicity test with rats (LD50 value: 570 mg/kg/day), restlessness and hyperventilation appeared immediately after administration, followed by a rapidly developing motor weakness. Tremors, clonic convulsions, dyspnea, and coma ensued until death (PATTY (5th, 2001)). From the LD50 value in the report, these were judged to be findings within the dose range corresponding to the guidance values for Category 2, and it was classified in Category 2 (nervous system) based on the toxic signs after administration.
9 Specific target organ toxicity - Repeated exposure Classification not possible
-
-
- - No data available.
10 Aspiration hazard Classification not possible
-
-
- - No data available.

Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Category 2
-
-
H401 P273
P501
It was classified in Category 2 from 96-hour LC50 = 3.99 mg/L for fish (Platichthys flesus) (AQUIRE, 2013).
11 Hazardous to the aquatic environment (Long-term) Category 2


-
H411 P273
P391
P501
If chronic toxicity data are used, then it is classified as "Not classified" due to being not rapidly degradable (not readily degradable, BOD 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1979)), and 72-hour NOEC = 10 mg/L for algae (Chlorella pyrenoidosa) (AQUIRE, 2013).
If acute toxicity data are used for a trophic level for which chronic toxicity data are not obtained, then it is classified in Category 2 due to being not rapidly degradable (not readily degradable, BOD 0% (Biodegradation and Bioconcentration Results of Existing Chemical Substances under the Chemical Substances Control Law, 1979)), and 96-hour LC50 = 4.5 mg/L for fish (Oryzias latipes) (AQUIRE, 2013).
By drawing a comparison between the above results, it was classified in Category 2.
12 Hazardous to the ozone layer Classification not possible
-
-
- - This substance is not listed in the Annexes to the Montreal Protocol.
