I have sent you MSDSs and Technical data sheets on the products you requested as well as the reports for the corresponding SCL#s. (I couldn’t find the information on Mirachem RTU, but I will continue to look.) The SCL# is the trial classification system used by the laboratory to identify specific trials performed at the Lab. A different SCL# represents a separate test and not a different product.
Terpenes are homocyclic hydrocarbons with a characteristic odor with low-volatility. They usually contain limonene (citrus based) or pinene (pine origins). The following is a list of pro’s and con’s for semi aqueous cleaners (of which terpenes are included).
| Pro’s
|
Con’s
|
| Excellent cleaning of difficult soils
|
Generally high initial costs
|
| Little or no residue following rinsing
|
Not as widely demonstrated as aqueous or solvents
|
| Neutral solutions will not etch metals
|
Some may be incompatible with plastics, aluminum or magnesium
|
| Low surface tensions compared to water, allows for penetration into blind holes
|
Flammability; low flash point in some cleaners
|
| Low vapor pressure when emulsified with water
|
Odors
|
| Some are biodegradable with low toxicity
|
Discharge may have high BOD
|
| Capable of high soil loading while still maintaining cleaning ability
|
High soil loading may make recycling of some cleaners difficult
|
| No ozone depleting potential
|
Some contain significant concentrations of volatile organic compounds
|
| Organic effluent may have fuel value
|
Higher number of waste streams to manage when compared to of aqueous solvent systems
