Glossary of Terms

Acetone Replacement is classified as any quasi-solvent system used as an alternative to acetone to effectively eliminate health hazards, fire risks, and acetone waste streams.
Non-Polar Solvents contain bonds between atoms with similar electro-negativities, such as carbon and hydrogen (such as gasoline). Bonds between atoms with similar electro-negativities will lack partial charges; it's this absence of charge which makes these molecules "non-polar".

Polar Aprotic have large dipole moments (aka "partial charges"); they contain bonds between atoms with very different electro-negativities, such as oxygen and hydrogen.

Aprotic Solvents cannot donate hydrogen
Dipole Moments can be defined as the product of magnitude of charges and the distance of separation between the charges.
Hansen Solubility Parameter Values were developed by Charles M. Hansen in his Ph.D. thesis in 1967 as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
California Air Resources Board (CARB) - According to the California Air Resources Board's, OTC Model Rule, and Federal VOC Standards, Surfasolve Products are exempt from VOC limit requirements because they are an 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 comprised 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.
