Low toxicity solvent composition

A low toxicity, homogenous, single phase solvent composition consisting essentially of:

• (a) an alicyclic carbonate having the formula ##STR4## wherein R.sub.1 and R.sub.2 are each selected from the group consisting of hydrogen, methyl, or ethyl, in an amount from about 25% to about 60% by weight of said composition;
• (b) a cyclic monoterpene in an amount from about 1% to about 20% by weight of said composition;
• and
• (c) a glycol ether or glycol ether acetate having the formula
• (R.sub.4 --O).sub.n2 --(R.sub.3 --O).sub.n1 --R.sub.5
• wherein n.sub.1 and n.sub.2 are the numerals 1 through 3, R.sub.3 is a hydrocarbon radical having 2 to 3 carbon atoms, R.sub.4 is a hydrogen or hydrocarbon radical having 1 to 4 carbon atoms, and R.sub.5 is a hydrogen or an acetate radical, in an amount from about 40% to about 60% by weight of said composition;
• said solvent composition further being substantially free of N-methyl pyrrolidone.
