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- 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.  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.  [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.  [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.
