- Benzenesulfonic acid, dimethyl, sodium salt
Yellowish liquid with a faint petroleum-like odor.
As anticaking and antiblocking agent in powdered products, such as powder detergents. To increase the solid contents of products during liquid drying processes or to improve detergent performance properties in washing. As solubiliser, coupling agent and processing aids in detergent manufacture and other industrial processes. Convert two phase systems into homogeneous mixtures

Hazards and Protection.
Store in a cool, dry area away from incompatible materials and direct heat. Store away from oxidizing agents. Mild steel drums should NOT be used for prolonged storage.
Wear dust mask when handling, rubber or plastic gloves, and safety goggles. Wear other general industrial clothing to minimise skin contact. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking or using toilet facilities.
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Clean-up personnel should wear full protective clothing including breathing protection in dusty environments. Cover spill with absorbent material. Sweep up and place in suitable containers for disposal.
Strong oxidizing agents.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
Nausea, vomiting, and diarrhea are common. Oral, pharyngeal and esophageal burns may occur following ingestion of low phosphate detergents which are generally more alkaline. Colitis, esophageal stricture, and irritation of mucous membranes have also been reported.
Occupational asthma has been reported. Aspiration may result in upper airway edema and significant respiratory distress. Difficulty in breathing has been described in animals inhaling high concentrations of anionic surfactants.
Skin irritation has been reported after prolonged occupational dermal contact. Skin dryness, irritation, and contact dermatitis have been reported following varying degrees of exposure to detergents.
Immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 4 ounces/120 ml in a child). Spontaneous vomiting frequently occurs following ingestion. If spontaneous vomiting does not occur then significant ingestion is unlikely. Administration of activated charcoal is unnecessary. Observe patients with ingestion carefully for the possible development of esophageal or gastrointestinal tract irritation or burns. If signs or symptoms of esophageal irritation or burns are present, consider endoscopy to determine the extent of injury. Patient should be evaluated for burns to the mouth and esophagus following ingestion of low phosphate detergents which are generally more alkaline.
Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.
Remove contaminated clothing, wash exposed area with copious amounts of water. A physician should examine the area if irritation or pain persists.
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
