SODIUM BORATE, DECAHYDRATE

ICSC: 0567

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
WHITE CRYSTALS OR CRYSTALLINE POWDER.

CHEMICAL DANGERS:
The substance is a weak base.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/mł (ACGIH 1996).
MAK not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, kidneys and liver, when ingested. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Animal tests show that this substance possibly causes toxic effects upon human reproduction.
