Abstract: The present invention relates to new and improved germicidal compositions having spermicidal properties comprising of a major amount of a mixture of n--C.sub.12-18 alkyl dimethyl benzyl ammonium halides and n--C.sub.12-14 alkyl dimethyl ethylbenzyl ammonium halides and a minor amount of a wetting agent selected from the group consisting of non-ionic, cationic and/or amphoteric surfactants and mixtures thereof.Spermicidal-germicidal compositions of the present invention possess new, improved and unexpected properties, particularly with respect to being biologically active against a wide range of organism including the venereal type organisms such as Neisseria gonorrhea, Treponema pallidum and other spirochetes, Hemophilus ducreyii, flagellates, such as Trichomonas vaginalis and related organisms. The compositions of the present invention have been found to exhibit spermicidal properties and, therefore, are particularly useful as a contraceptive. They are non-irritating towards vaginal tissues.

Abstract: The present invention relates to a method for embalming the body of a deceased human being, and to materials for use therein. More specifically, the invention provides a method in which a composition comprising certain specified quaternary ammonium compounds is applied to the skin of the body for the purposes of preventing decay, preventing the growth and spread of disease-causing organisms and retaining life-like appearance.

Abstract: Compositions for control of dental plaque comprising a synergistic mixture of an n-C.sub.12-18 alkyl dimethyl benzyl ammonium halide, an n-C.sub.12-14 alkyl dimethyl ethylbenzyl ammonium halide and a water-soluble or water dispersible ester of tributyl tin oxide.
