Storage & Handling

Storage & Handling

Handle liquid STEPANQUAT products with care; use away from sparks and open flame. Use in well ventilated area. Avoid contact with eyes, nose or prolonged skin contact. Gloves, protective clothing, safety goggles and face shield should be worn when handling STEPANQUAT products. Wash thoroughly after handling products. It is recommended that STEPANQUAT products be stored in sealed containers and kept in a cool, dry place. If material is frozen, it should be heated gently and stirred to ensure it is homogeneous before use.

Bulk Storage Information

STEPANQUAT quaternaries can be stored in vessels of 316 stainless steel or fiberglass with a corrosion liner. Contact between quaternaries and anionic materials must be avoided. At use dilution, STEPANQUAT quaternaries are non-corrosive to most plastics, natural rubber, stainless steel, monel metal, iron, brass, aluminum, lead and tin; however, STEPANQUAT quaternaries as supplied, may be corrosive to the materials listed above. Liquid STEPANQUAT products should be stored between 29 – 49 °C (85 – 120 °F). An internal hairpin coil of 316 stainless steel with low pressure steam (under 50 psig) should be used if heating is required. Mild agitation is recommended while storing to maintain homogeneity. Pumps, pipes and transfer lines should be 316 stainless steel. Rubber hoses with Teflon cross-linked polyethylene with 316 stainless steel fittings are recommended for loading and unloading.

Workplace Exposure

Occupational exposure can occur primarily through skin contact or via inhalation of vapors and/or mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
