sodium tetraborate usage and synthesis

chemical properties	white solid
general description	pale yellow solid or thick liquid with a faint odor of detergent. mixes with water. soap bubbles may be produced.
air & water reactions	water soluble.
reactivity profile	sodium peroxoborate is incompatible with the following: zirconium, strong acids, metallic salts . the true peroxoborate has been reported to detonate on light friction. the common "tetrahydrate" is not a peroxoborate, sodium tetraborate is relatively stable under mild grinding with other substances.
health hazard	no adverse effects from inhaling borax have been reported. ingestion may cause acute or chronic effects; initial symptoms are nausea, vomiting, and diarrhea; these may be followed by weakness, depression, headaches, skin rashes, drying skin, cracked lips, and loss of hair; shock may follow ingestion of large doses and may interfere with breathing. eye contact with powder or solutions may cause irritation; no chronic effects have been recognized, but continued contact should be avoided. local skin irritation may result from contact with powder or strong solutions; the latter may cause chronic dermatitis on prolonged contact, and if skin is broken, enough boron may be absorbed to cause boron poisoning (symptoms are similar to those for ingestion).
fire hazard	behavior in fire: compound melts to a glassy material that may flow in large quantities and ignite combustibles elsewhere.
