13 Oxidizing liquids Not applicable - - - - Solid (GHS definition)
14 Oxidizing solids Not classified - - - - This substance is inorganic compound containing oxygen, but it is classified as "Not classified" based on the description of "Niet van toepassing" (Dutch: Not correspond) (IUCLID (2000)).
15 Organic peroxides Not applicable - - - - Inorganic compound
16 Corrosive to metals Classification not possible - - - - Test methods applicable to solid substances are not available.

HEALTH HAZARDS

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 ...
The two LD50 values for rats were documented to be 1870 mg/kg (HSDB (2001), IUCLID (2000)), and > 2000 mg/kg (IUCLID (2000)). Based on the data, Category 4 or "Not classified" (corresponding to Category 5 or "Not classified" in the UN-GHS classification) were adopted for the substance. Therefore, from the viewpoint of selecting the category with greater hazard, the substance was classified as Category 4.
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 Category 2 Warning H315: Causes skin irritation P302+P352: IF ON SKIN: Wash with plenty of soap and water.
P332+P313: If skin irritation occurs: Get medical advice/attention.
P264: Wash ... thoroughly after handling.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
P321: Specific treatment (see ... on this label).
P362: Take off contaminated clothing and wash before reuse.
The substance was classified as Category 2 based on the results of "irritating" in the Draize test using rabbits in which irritation index was 2.5 (maximum value was 8) (IUCLID (2000)).
3 Serious eye damage/eye irritation Category 2A Warning H319: Causes serious 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.
P280: Wear protective gloves/protective clothing/eye protection/face protection.
The substance was classified as Category 2A based on the results of "irritating" in the Draize test using rabbits in which average scores of 2.17 for cornea opacity, 1.33 for iritis, 3.00 for conjunctivae redness and 4.00 for chemosis were reported, and irritation index was 63.2 (maximum value 110)(IUCLID (2000)). In another rabbit test, irrigation of the surface of the eyes with 10% solution at pH 11.6 for 30 seconds caused pain and very slight transient optical irregularity of epithelium (HSDB (2001)).
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 - - - - Because no in vivo test data available, the classification was not possible. As relevant information, as for in vitro test, there are negative results in the Ames test and the chromosomal aberration test using CHL cells (IUCLID (2000)).
6 Carcinogenicity Classification not possible - - - - No data available.
7 Reproductive toxicity Classification not possible - - - - In the oral administration tests using pregnant rats and mice during the organogenetic period, there was no clearly discernible effect on nidation or maternal or fetal survival, and the number of abnormalities seen in either internal or skeletal tissues of the test groups did not differ from the number occurring spontaneously in the vehicle-treated controls in both species (IUCLID (2000)). However, since there was no data on the sexual functions and fertility of parental animals, the substance was classified as "Classification not possible".
8 Specific target organ toxicity - Single exposure Classification not possible - - - - No data was available. Due to alkalinity, this substance might irritate the airway via inhalation (HSDB (2001)).
9 Specific target organ toxicity - Repeated exposure Classification not possible - - - - No data available.
10 Aspiration hazard Classification not possible - - - - No data available.

ENVIRONMENTAL HAZARDS
Hazard class Classification Symbol Signal word Hazard statement Precautionary statement Rationale for the classification
11 Hazardous to the aquatic environment (Acute) Not classified - - - - Classified as "Not classified" from its 48h-LC50 = 630 mg/L for crustacea (Ceriodaphnia dubia) (AQUIRE, 2011).
11 Hazardous to the aquatic environment (Long-term) Not classified - - - - Classified as "Not classified" since it is not non-water soluble (water solubility: 500000 mg/L (PHYSPROP Database, 2011)) and its acute toxicity is "Not classified".
12 Hazardous to the ozone layer Classification not possible - - - - This substance is not listed in Annexes to the Montreal Protocol.
