Abstract
Abstract This invention relates to a method for disinfecting or sterilizing medical, surgical, dental instruments or other objects in liquid phase with improved sporicidal compositions. The method object of the invention is based upon the synergistic effects observed when combining non-ionic and anionic surfactants with aqueous or alcoholic glutaraldehyde solutions. The method can be used also with ultrasonic irradiation over a wide frequency range (10 to 850 kHz). Two types of particularly effective synergistic sporicidal compositions are also described. Another modification is the use of the composition for disinfecting broiler eggs in breeder farms and commercial hatcheries.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
A method of disinfecting and sanitizing fowl eggs comprising contacting said eggs with a sufficient amount of a composition to disinfect and sanitize comprising from about 0.02% to about 5% of glutaraldehyde and from about 0.01% to 1% of a nonionic surface active agent which is an ethoxylate of isomeric linear alcohols having the following formula: ##EQU2## wherein n is 9 to 13 and x is 9 to 13.
Claim 2
Independent Claim
69 words
A method of disinfecting and sanitizing fowl eggs comprising contacting said eggs with a sufficient amount of a composition to disinfect and sanitize comprising from about 0.02% to about 5% of glutaraldehyde and from about 0.01% to 1% of a nonionic surface active agent which is an ethoxylate of isomeric linear alcohols having the following formula: ##EQU2## wherein n is 9 to 13 and x is 9 to 13.
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the composition contains at least one solvent selected from the group consisting of water and lower alcohol.
Claim 4
Dependent Claim
29 words
