Refer for medical attention.  •INGESTION Nausea. Vomiting. Diarrhoea. Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment. Separated from strong oxidants and strong acids. Provision to contain effluent from fire extinguishing. Store in an area without drain or sewer access. Signal: Warning Excl mark Harmful if swallowed Harmful in contact with skin Causes eye irritation Causes skin irritation May cause respiratory irritation Toxic to aquatic life SEE IMPORTANT INFORMATION ON BACK ICSC: 0502 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards SODIUM LAURYL SULFATE ICSC: 0502 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: WHITE SOLID IN VARIOUS FORMS , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on burning producing toxic and corrosive gases including carbon monoxide (See ICSC 0023, 0074 and 1202). Reacts with strong oxidants and strong acids . OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body through the skin 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 is irritating to 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: 204°C Density: 400-600 kg/m³ Solubility in water, g/100 ml at 20°C: 15 (moderate) Octanol/water partition coefficient as log Pow: 1.6 ENVIRONMENTAL DATA The substance is toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment. N O T E S ADDITIONAL INFORMATION ICSC: 0502 SODIUM LAURYL SULFATE (C) IPCS, CEC, 1994
