Abstract: Method of preparing a fixed biological implantation material in which an implantation material is fixed with an aldehyde and the excess aldehyde is bound by an aminodicarboxylic acid in an acidic medium.

Abstract: A process for sanitizing, disinfecting, and killing spores involves providing a tangible object made from polymeric material impregnated with an aqueous glutaraldehyde solution which is packaged in an air-tight enclosure, removing the impregnated tangible object from the enclosure, and applying the impregnated tangible object to the surface to be sterilized and/or sanitized and disinfected so as to expose spores, bacteria, virus, and other microorganisms present on the surface to the action of the glutaraldehyde solution. A sanitary attachment for a receiver or mouthpiece of a telephone made from plastic material incorporating a glutaraldehyde solution. A fabric made from cellulosic or plastic material having sporicidal and/or sanitizing and disinfectant activity as a result of being impregnated with a glutaraldehyde solution.

Abstract: Embalming preparations, which are far less noxious than previously known compositions, comprise a combination of a disinfectant and a plant growth regulating compound. The compositions achieve anti-microbial potency at concentrations of these ingredients far lower than the concentration levels of disinfectants found in known embalming preparations.

Abstract: The present provides a preservative comprising:(a) a first component selected from the group consisting of benzoic acid, formaldehyde, a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one in a ratio of about 5:1 to 1:5, benzisothiazalone, and mixtures thereof; and(b) a second component having the following formula: ##STR1## wherein x is about 2 to 33 and R is H or CH.sub.3 and mixtures thereof; wherein said second component is present in an amount at which said second component acts synergistically with said first component to kill or inhibit the growth of microorganisms.
