Patent ID: 8110538

Claim:
A microbicidal and decontaminant composition comprising: an aqueous solution of peroxides and peracids having equilibrium reaction products; an anionic photoreactive surfactant comprising a phosphate ester comprising a hydrophilic polyoxyethylene chain having a range of PEO-3 to PEO-9 and an R-terminal group selected from the group consisting of a lipophilic alkyl chain having a range of C9 to C13 and an nonylphenol; and a non-ionic polymer containing lactam which is polyvinyl pyrrolidone in an amount from approximately 0.015% to approximately 6% by weight, wherein said non-ionic polymer containing lactam interacts with said peroxides and said peracids by forming complexes; and wherein said non-ionic polymer containing lactam forms associations and adducts with said anionic photoreactive surfactant containing phosphate ester, said associations and adducts providing additional reactive chemistry that enhances the microbiocidal efficacy of the compositions.
