Abstract
Abstract An improved disinfecting and sterilizing composition having low odor and irritation potential is disclosed. The composition is an aqueous solution containing a 2 to 6 carbon atom dialdehyde and may also contain formaldehyde and a diol or monosubstituted diol of the formula RO(CH 2 CH 2 O) n CH 2 CH 2 OH; where R is H or CH 3 and n is an integer from 1 to about 22. Such compositions may be employed at a wide range of pH, from pH2 to pH9.
