Claims14
A composition which may be used as a concentrated alkaline disinfectant, said composition comprising:
- a) about 0.5% to about 10%, by weight, of a quaternary ammonium salt;
- b) about 1% to about 50%, by weight, of a guanidine derivative;
- c) about 1% to about 30%, by weight, of a C10- to C18-alcohol ethoxylate, wherein said ethoxylate has between about 5 and about 7 EO units;
- d) about 1% to about 15%, by weight, of alkylamine;
- e) about 0.05% to about 3%, by weight, of an acid, wherein said acid comprises at least one member selected from the group consisting of:
- 1) maleic acid;
- and
- 2) citric acid;
- and
- f) about 5% to about 60%, by weight, of aromatic alcohol.
A composition which may be used as an aqueous ready-to-use solution for disinfecting, said composition comprising about 0.5% to about 10%, by weight, of a concentrate, wherein said concentrate comprises:
- a) about 0.5% to about 10%, by weight, of a quaternary ammonium salt;
- b) about 1% to about 50%, by weight, of a guanidine derivative;
- c) about 1% to about 30%, by weight, of a C10- to C18-alcohol ethoxylate, wherein said ethoxylate has between about 5 and about 7 EO units;
- d) about 1% to about 15%, by weight, of alkylamine;
- e) about 0.05% to about 3%, by weight, of an acid, wherein said acid comprises at least one member selected from the group consisting of:
- 1) maleic acid;
- and
- 2) citric acid;
- and
- f) about 5% to about 60%, by weight, of aromatic alcohol.
A method which may be used to disinfect an instrument, said method comprising treating an instrument with a composition, wherein said composition comprises:
- a) about 0.5% to about 10%, by weight, of a quaternary ammonium salt;
- b) about 1% to about 50%, by weight, of a guanidine derivative;
- c) about 1% to about 30%, by weight, of a C10- to C18-alcohol ethoxylate, wherein said ethoxylate has between about 5 and about 7 EO units;
- d) about 1% to about 15%, by weight, of alkylamine;
- e) about 0.05% to about 3%, by weight, of an acid, wherein said acid comprises at least one member selected from the group consisting of:
- 1) maleic acid;
- and
- 2) citric acid;
- and
- f) about 5% to about 60%, by weight, of aromatic alcohol.
A method which may be used to control mycobacteria, said method comprising controlling mycobacteria with a composition, wherein said composition comprises:
- a) about 0.5% to about 10%, by weight, of a quaternary ammonium salt;
- b) about 1% to about 50%, by weight, of a guanidine derivative;
- c) about 1% to about 30%, by weight, of a C10- to C18-alcohol ethoxylate, wherein said ethoxylate has between about 5 and about 7 EO units;
- d) about 1% to about 15%, by weight, of alkylamine;
- e) about 0.05% to about 3%, by weight, of an acid, wherein said acid comprises at least one member selected from the group consisting of:
- 1) maleic acid;
- and
- 2) citric acid;
- and
- f) about 5% to about 60%, by weight, of aromatic alcohol.
