  • Publication number: 20060135472
    Abstract: The invention is a method comprising the use of diiodomethyl-para-tolylsulfone with water-soluble polymers, resulting in improved stability of diiodomethyl-para-tolylsulfone in various compositions with complex matrices. In a preferred embodiment of the invention, diiodomethyl-para-tolylsulfone is premixed with a solution of cationic polymer prior to addition to a formulation containing a complex matrix of ingredients that degrade diiodomethyl-para-tolylsulfone. As a result, diiodomethyl-para-tolylsulfone retains its chemical stability and antimicrobial activity.

  • Publication number: 20040109897
    Abstract: A solid antimicrobial composition that maintains free flow when exposed to high humidity and elevated temperature. The composition contains at least ortho-phthalic aldehyde and an anti-caking agent. A dispersant and/or a solubility enhancer may also be added. The composition is novel because it presents greatly decreased caking tendency as compared to OPA by itself, and preserves excellent flowing properties even after extended exposure to extreme temperature and humidity conditions.
