Kit for producing foams containing bispyridinium alkane

Abstract

A kit for the production of an antimicrobial foam includes: a) a liquid composition which includes a1)one or more bispyridinium alkane and a2)one or more surfactants selected from non-ionic surfactants, amphoteric surfactants and cation-active surfactants, wherein the composition is formulated so that a foam can be produced therefrom, and b) a device for producing the foam from the composition. By using the bispyridinium alkanes the foam stability of liquid and surfactant-containing compositions is increased.

Claims

1. Kit for the production of an antimicrobial foam consisting of: (a) a liquid composition consisting of: (a1) 0.04 to 0.2 wt % octenidine dihydrochloride, (a2) 0.02 to 2 wt % cocamidopropyl betaine, and (a3) water as a solvent, wherein the composition is formulated so that a foam can be produced therefrom; and (b) a foam dispenser for foaming the composition with air.

2. The kit according to claim 1, wherein the octenidine dihydrochloride is present in an amount of 0.05 to 0.15 wt. %.

3. The kit according to claim 1, wherein the cocamidopropyl betaine is present in an amount of 0.03 to 0.5 wt. %.

4. The kit according to claim 1, wherein the octenidine dihydrochloride is present in an amount of about 0.08 wt %.

5. The kit according to claim 1, wherein the cocamidopropyl betaine is present in an amount of about 0.04 wt %.

Description

(1) The results of corresponding tests are also shown in FIGS. 1 and 2,

(2) FIG. 1 shows foams produced by the formulations according to table 1 (immediately) and

(3) FIG. 2 shows foams produced by the formulations according to table 1 (after 3 minutes).

(4) FIG. 1 shows the foam of example 1 (cf. 1/1, according to the invention), of examples 2 and 3 (1/2 and 1/3, without bispyridinium alkane a1), comparative example) and of example 4 (without non-ionic surfactant a2) comparative example) immediately after the foam has been produced.

(5) Said foams are then shown in FIG. 2 after 3 minutes, wherein the foam of example 4 (2/4, comparison) has completely collapsed, whereas the foam of the formulation according to the invention is still very well defined and stable by comparison (2/1).
