Abstract
Abstract This invention relates to a method for disinfecting or sterilizing medical, surgical, dental instruments or other objects in liquid phase with improved sporidical compositions. The method object of the invention is based upon the synergistic effects observed when combining nonionic 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.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
51 words
A sterilization and disinfectant composition comprising from about 0.1% 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: ##EQU3## wherein n is 9 to 13 and x is 9 to 13.
Claim 2
Dependent Claim
51 words
A sterilization and disinfectant composition comprising from about 0.1% 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: ##EQU3## wherein n is 9 to 13 and x is 9 to 13.
Claim 3
Dependent Claim
30 words
The disinfecting and sterilizing composition of claim 1 also containing a sufficient quantity of a lower alkanol to make a final alcoholic concentration of from about 60% to about 75%.
Claim 4
Dependent Claim
24 words
A sporicidal composition having a pH of 6.5 consisting essentially of 2% by weight glutaraldehyde, 1% by weight nonionic surface active agent and water.
