Abstract
Abstract An antiseptic composition is described containing a phenolic or quaternary ammonium bactericide and, as a potentiating agent, a water-soluble polyphosphonic acid compound having the formula WHEREIN N IS AN INTEGER FROM 2 TO 3 INCLUSIVE, M is a member selected from the group consisting of hydrogen and cations, and Z is a connecting radical equal in valence to n and containing not more than about 12 atoms, exclusive of hydrogen, in chemical combination, as well as compositions containing the foregoing and other additives such as are found in sanitizing compositions, antiseptic detergent compositions, cosmetic compositions, drilling mud compositions and the like.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
86 words
An antiseptic composition comprising a bactericide selected from the class consisting of phenolic bactericides and, as a potentiating agent, a water-soluble amino tri(lower alkylidene phosphonic acid) compound having the formula wherein X and Y are members selected from the group consisting of hydrogen and lower alkyl, and M is a member selected from the group consisting of hydrogen, alkali metal ions, ammonium ions and amine ions, with the proviso that said potentiating agent is present in an amount sufficient to improve the activity of said bactericide.
Claim 2
Dependent Claim
14 words
The composition of claim 2, wherein said potentiating agent is pentasodium amino tri(methylene phosphonate).
Claim 3
Dependent Claim
99 words
An antiseptic composition comprising a bactericide selected from the class consisting of phenolic bactericides and, as a potentiating agent, a water-soluble lower alkylidene diphosphonic acid compound having the formula wherein X is a member selected from the group consisting of hydrogen and lower alkyl, Y is a member selected from the group consisting of hydrogen, hydroxyl and lower alkyl, and M is a member selected from the group consisting of hydrogen, alkali metal ions, ammonium ions and amiNe ions, with the proviso that said potentiating agent is present in an amount sufficient to improve the activity of said bactericide.
Claim 4
Dependent Claim
14 words
