preferably one having a lip value less than 15.5 MPa 112 . In yet other embodiments, the solvent component can consist of, or consist essentially of, water and two or more organic liquids, with the resulting solvent component having lip value that can be calculated using formula (I); again, pref› erence is given to mixtures of species of the same genus of organic liquids, e.g., two ethers or two alcohols rather than one ether and one alcohol. 

[0062] With respect to organic liquids that can be employed in the solvent component, those which are mis- 

cible with one another and/or water are preferred. Non› limiting examples of potentially useful organic liquids include ketones such as acetone, methyl butyl ketone, methyl ethyl ketone and chloroacetone; acetates such as amyl acetate, ethyl acetate and methyl acetate; (meth)acry› lates and derivatives such as acrylamide, lauryl methacrylate and acrylonitrile; aryl compounds such as benzene, chlo› robenzene, fluorobenzene, toluene, xylene, aniline and phe› nol; aliphatic alkanes such as pentane, isopentane, hexane, heptane and decane; halogenated alkanes such as chloro› form, methylene dichloride, chloroethane and tetrachloro› ethylene; cyclic alkanes such as cyclopentane and cyclo› hexane; and polyols such as ethylene glycol, diethylene glycol, propylene glycol, hexylene glycol, and glycerol. When selecting such organic liquids for use in the solvent component of the composition, possible considerations include avoiding those which contain a functional group that will react with either the acid(s)/base(s) or salt(s) employed in the composition and favoring those which possess higher regulatory pre-approval limits. 

[0063] Preferred organic liquids include ethers and alco› hols due to their low tissue toxicity and environmentally friendliness. These can be added at concentrations up to the solubility limit of the other ingredients in the composition. 

[0064] Ether-based liquids that can be used in the solvent component include those defined by the following general formula

*includes unsaturation at the 9 position 

where x is an integer of from O to 20 ( optionally including, where 2sxs20, one or more points of ethylenic unsatura› tion), y is O or 1, z is an integer of from 1 to 4, R 2 is a C$_{1}$-C$_{6 }$ linear or branched alkylene group, R $^{1 }$is a methyl, isopropyl or phenyl group, and Z is a hydroxyl or methoxy group. Non-limiting examples of glycol ethers (formula (II) com› pounds with Z=OH) that can be used in the solvent com› ponent are set forth below in Table 2. 

[0065] Cyclic and C$_{1 }$-C$_{16 }$ acyclic (both linear and branched, both saturated and unsaturated) alcohols, option› ally including one or more points of ethylenic unsaturation and/or one or more heteroatoms other than the alcohol oxygen such as a halogen atom, an amine nitrogen, and the like, can be included in the solvent component of the composition. Non-limiting examples of representative examples are compiled in the following table.
