Alternative Solvent Degreasers
These degreasing and cleaning solvents are marketed as alternatives to halgonated solvents—especially chlorinated solvents. In some cases, these solvents require more time or stronger physical action for cleaning surfaces. All have lower rates of evaporation and drying than the chlorinated solvents they replace.
Safety Information
Most alternatives are safer than chlorinated solvents because their slow evaporation rates result in low worker exposure. Consider the following safety information when selecting an alternative chemical.
Exposure limit. Exposure limit estimates, based on
eight-hour exposure, given in the following table are
made by the Occupational Safety and Health Administration (OSHA), the American Congress of Governmental Industrial Hygienists (ACGIH), or the product manufacturer. OSHA establishes the legally enforceable standard. But, the ACGIH standard is generally recognized as the prudent industrial standard in the absence of an OSHA limit or when new information suggests an established OSHA limit is too lenient.
Vapor hazard ratio. The vapor hazard ratio is the likelihood that an exposure limit will be exceeded with normal use. It does not apply if the solvent will be sprayed or atomized. It is estimated by dividing the vapor pressure of a product, the tendency of a solvent to get into the air, by the exposure limit, its risk. The higher the number, the greater the chance the exposure limit will be exceeded due to solvent evaporation. This is a comparison of relative risks, this scale does not indicate if a chemical is unsafe.
Hazard rating. A hazard rating for health, flammability and reactivity is assigned to pure chemicals by the National Fire Protection Association (NFPA). A similar rating can be assigned to products by their manufacturer using the National Paint and Coatings Association (NPCA) Hazardous Materials Information Systems (HMIS) criteria. Because the HMIS is more subjective, the table on the following pages gives HMIS ratings only in the absence of NFPA ratings.
Alternative Solvent Degreasers
The cleaning claims in this reference list are made primarily by the manufacturer. Some claims are augmented by reports from the U.S. Environmental Protection Agency (EPA) and third parties. MnTAP maintains the following list of alternative solvent degreasers solely as a service to Minnesota companies. This is not a complete list of available suppliers and products, and does not represent an endorsement by MnTAP. MnTAP, by providing this list, does not represent that the products do or do not ensure compliance with environmental and safety laws in any specific application.
Table Key
a Vapor pressure measured at approximately 20º C.
b Vapor hazard ratio is calculated by dividing the vapor pressure by 760 mm Hg, multiplying by one million to estimate the equilibrium vapor concentration in parts per million, and then dividing by the exposure limit in parts per million.
c Estimated by the manufacturer, based on HMIS criteria.
d Practically non-flammable.
