  • Patent number: 4719106
    Abstract: New iodophor compositions are provided which are mixtures of polydextrose-iodine and polyvinylpyrrolidone-iodine. Such mixtures containing polydextrose-iodine and polyvinylpyrrolidone-iodine, wherein the ratio by weight of polydextrose to polyvinylpyrrolidone is between 20-80: 80-20, have an immediate bactericidal activity upon application and also a long lasting microbicidal activity. The immediate microbicidal acitivity is faster and more effective than by the use of either the polydextrose-iodine alone or the polyvinylpyrrolidone-iodine alone, and the effect is more long lasting than in the case of the use of either polydextrose-iodine alone or polyvinylpyrrolidone-iodine alone.

  • Patent number: 4668510
    Abstract: New iodophors are provided which exhibit effective degerming of skin, nucous membranes of animals and surfaces of inanimate objects and which provide broad spectrum microbicidal action without toxicity or irritation. The iodophors of the invention are complexes of iodine with polydextrose or with the polymer resulting from the copolymerization of sucrose and epichlorohydrin. The invention further relates to germicidal compositions containing such complexes and to methods of producing the complexes.
