New compositions, for example, corrosion inhibited compositions, and the like compositions and new methods of using such compositions are disclosed. Such compositions may be liquid solutions, for example, substantially without solid material formation and/or crystal formation, and may include different concentrations of organic acid components and/or different combinations of organic acid components relative to previous compositions. The present compositions may be used as antifreeze coolant compositions or formulations, for example, in the cooling systems of internal combustion engines.
