wherein the at least one solvent is selected from the group consisting of benzyl alcohol, 3-(1-menthoxy)propane-1,2-diol, p-menthane-3,8-diol, propylene glycol, diethylene glycol, dipropylene glycol, triacetine (glycerine triacetate) medium chain triglyceride, and mixtures thereof.

2. The malodor eliminating composition of claim 1 , wherein the at least one lactone is selected from the group consisting of angelica lactone alpha, angelica lactone beta, 2(5H) furanone, and mixtures thereof.

3. The malodor eliminating composition of claim 1 , further comprising a malodor masking compound.

4.
