Abstract
Abstract A biocidal complex for contact sterilization prepared by thoroughly mixing together about 25-55% of a vinyl oxozaline fatty or carboxylic acid ester of tris (hydroxymethyl) amino methane having three alkyl groups, each of 1 to 17 carbon atoms and all alkyl groups being the same or different and two different biocide compositions combined or reacted with the ester. The disclosure also includes biocidal materials, such as paints, toiletries, coating compositions, sterilizing compositions, adhesive-sealant compositions, pharmaceutical compositions, and similar products having as an active ingredient the above biocidal composition and a compatiblecarrier material.
