Regulatory & Compliance
- Certifications & Compliance
- Chemical Inventories
- Clearances
- The international inventories (country clearances) of STEPAN MWA-503 can be found in Section 15 of the Safety Data Sheet (SDS). It is the responsibility of the formulator to review the chemical control regulations for each country where the end-product is intended to be sold or used.
- Per the California Air Resources Board’s (CARB) Consumer Product Rule, OTC Model Rule and Federal VOC Standards, STEPAN MWA-503 is exempt from VOC limit requirements because it is a LVP-VOC (low vapor pressure VOC). All regulations define an LVP-VOC as a compound or mixture which meets one of the following criteria: 1) The compound has a vapor pressure of less than 0.1 mm Hg at 20°C; 2) the compound has more than 12 carbon atoms, or a mixture compromised solely of compounds with more than 12 carbon atoms, and the vapor pressure is unknown or 3) the compound has a boiling point greater than 216°C.
Safety & Health
- Health Effects
STEPAN MWA-503 is practically nontoxic (LD₅₀>5 g/kg). Undiluted product is mildly irritating to skin and eyes. See SDS for more information.
Packaging & Availability
- Packaging Type
Storage & Handling
- Storage & Handling
- Normal safety precautions (i.e. gloves and safety goggles) should be employed when handling STEPAN MWA-503. Contact with eyes and prolonged contact with skin should be avoided. Wash thoroughly after handling materials. Product temperatures over 130°F (54°C) are not recommended. Being derived from soybean oil, STEPAN MWA-503 contains polyunsaturated fatty acid methyl ester that can spontaneously combust. Oily rags, presenting a large surface area for air contact, should be washed out or stored where there can be no fire hazard. See SDS for more information.
- Bulk Storage Information: STEPAN MWA-503 can be stored in vessels of carbon steel, but 316 or 304 stainless steel is preferred. Tanks should be closed with venting through a gooseneck vent. STEPAN MWA-503 should be stored between 50-110°F (10-43°C). External steam panel coils can be used if heating is required. Pumps, pipes, and transfer lines can be carbon steel, but 316 or 304 stainless is preferred. Rubber hoses are not recommended for extended use as STEPAN MWA-503 may degrade rubber.
- Recommended Drum Storage: Drums should be stored sealed at temperatures of 50-110°F (10-43°C).
- Workplace Exposure
Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists. Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures. See the SDS for further information.
