ABSTRACT:
The present invention relates to a method to decrease the flammability of normally flammable alcohols and solvents. The additive is Alpha Terpineol, which will increase the flash point of flammable alcohols or solvents, by blending the Terpineol into the flammable solvent or alcohol. Solvents such as acetone, methanol, ethylacetate, ethanol and xylene, to name a few, increases flash points by 50° C. to 60° C., by addition of 12-14% terpineol. The said solvent can then be blended with other organic solvents to produce performance solvents, such as paint strippers with flash points greater than 140° F. and meet Federal and state Volatile Organic Compound regulations.
