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. Sore throat. Local exhaust or breathing protection. Fresh air, rest.  •SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES Redness. Pain. Safety goggles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.  •INGESTION Diarrhoea. Vomiting. Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P1 filter respirator for inert particles). Separated from acids.

International Chemical Safety Cards SODIUM DODECYLBENZENE SULPHONATE ICSC: 1189 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE TO YELLOW SOLID IN VARIOUS FORMS. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating producing toxic and irritating fumes (sulfur oxides). Reacts with acids or acid fumes producing toxic and irritating fumes (sulfur oxides). OCCUPATIONAL EXPOSURE LIMITS: TLV 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, especially if powdered. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Melting point: >300°C Solubility in water, g/100 ml at 25°C: 20 Octanol/water partition coefficient as log Pow: 0.45 ENVIRONMENTAL DATA N O T E S Santomerse #1, Conoco C-50, Biosoft D-40, Marlon 375 and Neopelex 05 are trade names.
