LANXESS Corp.’s Material Protection Products (MPP) business unit recently received Environmental Protection Agency (EPA) registration for a new Bronopol-based biocide formulation. The biocide is a VOC-free synergistic blend of Bronopol (2-bromo-2-nitropropane-1,3-diol) and smaller percentages of CMIT/MIT (5-chloro-2-methyl-4-isothiazolin-3-one/2-methyl-4-isothiazolin-3-one). LANXESS is marketing this formulation under the PREVENTOL^® P 91 brand name. The group also sells PREVENTOL P 100 Preservative (100% Bronopol) and PREVENTOL P 30 (VOC-free 30% Bronopol solution). 

“With the registration of PREVENTOL P 91, our Bronopol portfolio is now much more flexible,” said Dr. Oliver Kretschik, market manager for the business. “We can now offer customers VOC-free options to meet their anti-bacterial needs and can also address problems that require a VOC-free full spectrum biocide and have additional options for sanitization measures.”

These Bronopol-based products are particularly effective against gram-positive and gram-negative bacteria, including sulfate-reducing, anaerobic types. In addition, these biocides are effective at preventing the formation of biofilms and slime deposits.
