摘要:
The invention relates to a kit for the production of an antimicrobial foam comprising: a) a liquid composition which comprises 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.

The invention relates to antimicrobial compositions which contain (i) at least one zinc compound selected from zinc salt and zinc oxide, (ii) at least one glycerine monoalkyl ether of the general formula
R-O-CH 2 -CHOH-CH 2 OH,
wherein R is a branched or unbranched C 1 -C 24 alkyl group, wherein the alkyl group can be substituted with one or more hydroxy and/or C 1 -C 4 alkoxy group(s) and/or the alkyl chain can be interrupted by up to four oxygen atoms, (iii) at least one antioxidant and optionally (iv) one or more alkanediols, wherein the weight ratio (w/w) of component (ii) to component (iii) is at least 10:1. The compositions are used in cosmetic and pharmaceutical products and already have broad antimicrobial activity, in particular against Pseudomonas aeruginosa, at active substance contents of only about 3 wt.%.
摘要:
The invention relates to a process for the production of an alcoholic gel which comprises a) at least 20% by weight of aliphatic alcohol and b) at least one thickener, in which 1) a phase I is provided, where at least one thickener based on acrylic acid polymer is dispersed in a liquid initial charge, where the liquid initial charge comprises one or more aliphatic C 3 - to C 8 -alcohols, 2) a phase II is provided which comprises water and/or one or more aliphatic alcohols, 3) phase I and phase II are mixed together in order to produce a mixture, and 4) at least one neutralizing agent is added to the mixture.
Surprisingly, during the production process according to the invention and also upon use of the alcoholic gels according to the invention, lump formation in the gels does not arise.
