【Product Name】Dipotassium tetraborate
Physical and Chemical Properties
【Appearance】Odorless, white crystalline powder.
【Solubility in water】158 g/L (20℃)
【Usage】A component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound for fiberglass, as an insecticide, as a flux in metallurgy, and as a precursor for other boron compounds.
First Aid Measures
【Ingestion】If conscious, give several glasses of water or milk and induce vomiting by touching finger to back of throat. Get medical attention.
【Inhalation】Remove to fresh air. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is difficult, give oxygen if a qualified operator is available. Get medical attention.
【Skin】Wash with plenty of soap and water, then flush with water until all chemical is removed. Remove any contaminated clothing and wash before reuse. Get medical attention if irritation persists.
【Eyes】Immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention should discomfort or irritation persist.
Handling and Storage
【Storage】Store in a cool, dry area. Keep containers tightly closed and upright.
【Ingestion】Harmful if ingested. Symptoms include nausea, headache, chills and general weakness. Large doses may cause liver and kidney damage, convulsions, cardiac arrhythmias, and potentially fatal respiratory collapse. Overall toxicity estimated to be moderate.
【Inhalation】Product dusts may irritate the throat and respiratory tract.
【Skin】May cause irritation, especially if contact is prolonged or repeated. Prolonged exposure to broken or abraded skin may result in symptoms similar to those of ingestion.
【Eyes】Dusty or misty conditions can cause eye irritation.
Exposure Controls/Personal Protection
【Personal Protection】Wear full protective clothing (long-sleeve shirt and trousers) and cotton (or similar) gloves when handling dry product. Use impervious gloves for handling product solutions. Under normal conditions, wear safety glasses. Under dusty conditions, wear chemical safety goggles.
【Respirators】A high-efficiency NIOSH-approved dust respirator should be used for dusty conditions or when transferring product from containers.
Fire Fighting Measures
【Fire Fighting】Water or any standard extinguishing agent can be used. Use water spray to cool fire-exposed containers. Firefighters should wear full protective clothing and NIOSH- approved, self-contained breathing apparatus if fire produces irritating fumes.
【Fire Potential】Material will not burn but melts @ 815 C to form a glassy, flowable material that might ignite combustibles on contact.
Accidental Release Measures
【Small spills/leaks】Sweep or shovel spilled material into containers with a minimum of dusting. Close, label and store container for later disposal. Flush area with water to complete clean-up.
Stability and Reactivity
【Incompatibilities】Can react explosively if heated in the presence of zirconium.
【Stability】Stable under normal conditions.
