Gives off irritating or toxic fumes (or gases) in a fire. In case of fire in the surroundings: all extinguishing agents allowed. EXPLOSION EXPOSURE PREVENT DISPERSION OF DUST!  •INHALATION Cough. Sneezing. Ventilation, local exhaust, or breathing protection. Fresh air, rest.  •SKIN Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Mildly irritant. Safety spectacles. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Cough. Rinse mouth.

International Chemical Safety Cards FLUORESCENT WHITENING AGENT 1 ICSC: 1236 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE POWDER OR GRANULES. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic and irritating fumes including sulfur oxide and nitrogen oxides. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body through the skin. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly when dispersed. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Melting point: see Notes Solubility in water: poor ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Temperature of decomposition unknown in literature. MBBH 766, Tinopal, Mikephor, Blankophor and C.I. Fluorescent Brightener 260 are trade names. ADDITIONAL INFORMATION ICSC: 1236 FLUORESCENT WHITENING AGENT 1 (C) IPCS, CEC, 1994
