Wide Spectrum Liquid Preservative Formulation, Method for Preparation, Stabilized Iodopropargyl Solution, and Process to Eliminate or Slow Growth of Microbes

摘要

"LARGE SPECTRUM LIQUID PRESERVATION FORMULATION, METHOD FOR PREPARATION, STABILIZED IODOPROPANIL SOLUTION AND PROCESS TO ELIMINATE OR DELAY THE GROWTH OF MICROBIES". The present invention comprises a highly stable liquid formulation having broad spectrum preservative properties comprising a mixture of a dialcanol substituted DMH, an iodopropynyl compound, a stabilizer of a hydantoin, urea or derivatives thereof, and a hydroxyl solvent. Preferably the constituents are dimethylhydantoin, 3-iodo-2-propynylbutyl carbamate, dimethylhydantoin, and a glycolic solvent. The preservative preferably has a total formaldehyde content of 5% and less than 0.2% free formaldehyde. The composition is prepared successively by mixing the dialkanol-substituted dimethylhydantoin and the stabilizer, the hydroxyl solvent, and the iodopropynyl compound. Also described is a stabilized iodopropynyl compound preferably containing dimethylhydantoin as the stabilizer.
