Part II: 5.739 g of sodium 4-phenylbutyrate (Triple Crown America, Inc.), 0.125 g of methylparaben (Merck), 0.075 g of propylparaben (Merck), and 149.061 g of deionized water were mixed in a beaker and heated at 70° C. Part II was slowly added into part I and continually stirred at 400 rpm for 5 minutes to form a mixture. 2% Stabileze QM™ (prepared by dissolving 2 g of Stabileze QM™ in 98 g of deionized water, heating and stirring at 70° C. to form a paste, and cooling at room temperature) was added into the mixture and stirred for 5 minutes.
