A method of preparing a liquid lactic acid composition that has a total acid content of at least 94% (w/w) and that does not crystallize at a temperature above 10° C. includes obtaining a starting liquid lactic acid composition that has a total acid content of at least 94% (w/w) and that crystallizes at a temperature above 10° C. and incubating said starting liquid lactic acid composition at a temperature above the crystallization point of the starting liquid lactic acid composition for a time period to obtain the liquid lactic acid composition that does not crystallize at a temperature above 10° C.
