1 | Acute toxicity (Oral) | Category 4 | Warning | H302: Harmful if swallowed |
P301+P312: IF SWALLOWED: Call a POISON CENTER or doctor/physician if you feel unwell. P264: Wash ... thoroughly after handling. P270: Do not eat, drink or smoke when using this product. P330: Rinse mouth. P501: Dispose of contents/container to ... |
Based on its rat oral LD50 of 650 mg/kg (HSDB, 2005), sivex (CAS: 93-72-1) was classified into Category 4. | |
1 | Acute toxicity (Dermal) | Category 3 | Danger | H311: Toxic in contact with skin |
P302+P352: IF ON SKIN: Wash with plenty of soap and water. P280: Wear protective gloves/protective clothing/eye protection/face protection. P312: Call a POISON CENTER or doctor/physician if you feel unwell. P322: Specific treatment (see ... on this label). P361: Remove/Take off immediately all contaminated clothing. P363: Wash contaminated clothing before reuse. P405: Store locked up. P501: Dispose of contents/container to ... |
Based on its LD50 of > 0.32E+04 mg/kg reported in a rabbit dermal test (RTECS, accessed in November 2007), classification of silvex (CAS: 93-72-1) falls under Category 4 or the "Not classified" category. More refined classification is not possible. | |
1 | Acute toxicity (Inhalation: Gases) | Not applicable | - | - | - | - | Since the substance is a solid, it was classified into the "Not applicable" category. |
1 | Acute toxicity (Inhalation: Vapours) | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1): No data available. |
1 | Acute toxicity (Inhalation: Dusts and mists) | Not classified | - | - | - | - | Silvex (CAS: 93-72-1): No data available. |
2 | Skin corrosion/irritation | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1) is reported to be irritating to the skin (HSDB, 2005). However, since no detailed information is provided, classification is not possible. |
3 | Serious eye damage/eye irritation | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1) is reported to be irritating to the eyes (HSDB, 2005). However, since no detailed information is provided, classification is not possible. |
4 | Respiratory sensitization | Classification not possible | - | - | - | - | MCPP (CAS: 93-65-2): No data available. |
4 | Skin sensitization | Classification not possible | - | - | - | - | MCPP (CAS: 93-65-2): An open epicutaneous test using guinea pigs, gave negative results (IUCLID, 2000). However, since no other test results are available, classification is not possible. |
5 | Germ cell mutagenicity | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1): No data available. |
6 | Carcinogenicity | Category 2 | Warning | H351: Suspected of causing cancer |
P308+P313: IF exposed or concerned: Get medical advice/attention. P201: Obtain special instructions before use. P202: Do not handle until all safety precautions have been read and understood. P281: Use personal protective equipment as required. P405: Store locked up. P501: Dispose of contents/container to ... |
Since chlorophenoxy herbicides are rated as "2B" by IARC S7 (1987), the substance was classified into Category 2. | |
7 | Reproductive toxicity | Classification not possible | - | - | - | - | In the study on silvex (CAS: 93-72-1), cleft palates were observed in the offspring of mice treated orally at 379 mg/kg/day during gestation (IRIS, 1988). The effect of the treatment on dams is unclear. Based on this information, the substance was classified into Category 2. |
8 | Specific target organ toxicity - Single exposure | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1): No data available. |
9 | Specific target organ toxicity - Repeated exposure | Classification not possible | - | - | - | - | In a study in which dogs were fed with a diet containing silvex (CAS: 93-72-1) for 2 years, histological changes were observed in the liver in subject groups that received the doses which is equivalent to Category 1 doses (IRIS, 1988). Thus, the substance was classified into Category 1 (liver). |
10 | Aspiration hazard | Classification not possible | - | - | - | - | Silvex (CAS: 93-72-1): No data available. |
