Abstract
A method of raising the flash point of a green solvent includes adding from about 0.05 to 5.0 wt. % of at least one terpene alcohol, based on the weight of the at least one terpene alcohol and the green solvent. Green solvents are derived from organic matter, such as plants. They are not the product of petroleum feed stocks. Preferably, two terpene alcohols are added to the green solvent. Further, the addition of at least one terpene alcohol improves both the freeze resistance and the shelf life of the final green solvent solution.
