    (c) feeding the first reactant stream and the second reactant stream to a reaction vessel containing a catalyst;

    (d) reacting the hydroxy acid and the carboxylic acid in the reaction vessel and in the presence of the catalyst to form a reaction product therebetween, the reaction product comprising an acyloxy carboxylic acid compound; and

    (e) removing a first product stream comprising the acyloxy carboxylic acid compound from the reaction vessel;

    wherein a ratio of the carboxylic acid to the hydroxy acid fed to the reaction vessel ranges from 1;

    1 to 10;
