Based on the rat LD50 (oral route) value of 790mg/kg (Agricultural Chemical Registration Data (1999)). | |
1 | Acute toxicity (Dermal) | Not classified | - | - | - | - | Based on the rat LD50 (dermal route) value of >5,000mg/kg (Agricultural Chemical Registration Data (1999)). |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | - | Due to the fact that the substance is a solid according to the GHS definition and inhalation of its gas is not expected. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | No data available |
1 | Acute toxicity (Inhalation: Dusts and mists) | Classification not possible | - | - | - | - | Classification not possible because the available rat inhalation LC50 of >0.044mg/L (the upper limit of experimentally feasible range of concentrations) is not classifiable (Agricultural Chemical Registration Data (1999)). |
2 | Skin corrosion/irritation | Not classified | - | - | - | - | In rabbit skin irritation tests, only mild irritation reactions were seen immediately after the application. The reactions were fully reversible within 48 hours (Agricultural Chemical Registration Data (1999)). |
3 | Serious eye damage/eye irritation | Category 2B | - | Warning | H320: Causes eye irritation |
P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P337+P313: If eye irritation persists: Get medical advice/attention. P264: Wash ... thoroughly after handling. |
Based on the data from rabbit eye irritation tests (Agricultural Chemical Registration Data (2003)): "Slightly irritating, with effects fully reversible within 4 days." |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | No data available |
4 | Skin sensitization | Not classified | - | - | - | - | Based on no evidence of sensitization observed in guinea pig skin sensitization tests (Agricultural Chemical Registration Data (2003)). |
5 | Germ cell mutagenicity | Not classified | - | - | - | - | Based on negative data on in vitro reverse mutation tests (Agricultural Chemical Registration Data (1999)) and chromosome aberration tests (Agricultural Chemical Registration Data (1999)), and in vivo micronucleus tests on mouse bone marrow cells (Agricultural Chemical Registration Data (2003)). |

8 | Specific target organ toxicity - Single exposure | Category 2 (nervous system) | Warning | H371: May cause damage to organs (nervous system) |
P309+P311: IF exposed or if you feel unwell: Call a POISON CENTER or doctor/physician. P260: Do not breathe dust/fume/gas/mist/vapours/spray. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P405: Store locked up. P501: Dispose of contents/container to ... |
In rat single dose toxicity studies, clinical signs and symptoms including blepharoptosis, rigid limbs and weakness, staggering gait, reduced reflex, prone position, and coma were reported (Agricultural Chemical Registration Data (1999)). These effects were observed at dosing levels within the guidance value ranges for Category 2. | |
9 | Specific target organ toxicity - Repeated exposure | Category 2 (central nervous system) | Warning | H373: May cause damage to organs through prolonged or repeated exposure (central nervous system) |
P260: Do not breathe dust/fume/gas/mist/vapours/spray. P314: Get medical advice/attention if you feel unwell. P501: Dispose of contents/container to ... |
In rat subacute toxicity studies, evidence of lysis and vacuolization of brainstem neurons, and atrophy of anterior horn cells of spinal cord were reported (Agricultural Chemical Registration Data (1999)). These effects were observed at dosing levels within the guidance value ranges for Category 2. | |
10 | Aspiration hazard | Classification not possible | - | - | - | - | No data available |
Hazard class | Classification | Symbol | Signal word | Hazard statement | Precautionary statement | Rationale for the classification | |
---|---|---|---|---|---|---|---|
11 | Hazardous to the aquatic environment (Acute) | Category 1 | Warning | H400: Very toxic to aquatic life |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
It was classified into Category 1 from 48 hours LC50=0.169mg/L of the crustacea (Daphnia magna) (Agricultural Chemical Registration Data, 2004). | |
11 | Hazardous to the aquatic environment (Long-term) | Category 1 | Warning | H410: Very toxic to aquatic life with long lasting effects |
P273: Avoid release to the environment. P391: Collect spillage. P501: Dispose of contents/container to ... |
Since acute toxicity was Category 1 and there was no rapidly degrading (BIOWIN), and since there wasbio-accumulation (log Kow=4.05 (PHYSPROP Database, 2005)), it was classified into Category 1. |
