Mechanism of efficiency of DMDC DMDC can permeate through the cell membrane, and block the metabolism through reacting with the enzymes of microorganism, then achieve the purpose of sterilization. Even in very low additive amount, DMDC can effectively kill typical spoilage bacteria in beverage, and not affect the taste, flavor and color of the beverage. Furthermore, it could be rapidly and completely hydrolyzed to carbon dioxide and methanol, which are the natural ingredients of juice.

Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.
Description: It has excellent detergency, emulsification ,and foamability, it is easy to dissolve in water. As well as favorable hard-water resistant and high-biodegradation.
