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.

Kit for producing foams containing bispyridinium alkane

Antimicrobial compositions containing (i) at least one zinc compound selected from zinc salt and zinc oxide; (ii) at least one glycerine monoalkyl ether, R&#x2014;O&#x2014;CH&#x2014;CHOH&#x2014;CHO, wherein R is a branched or unbranched C-Calkyl group that can be substituted with one or more hydroxy and/or C-Calkoxy 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; the weight ratio of (ii) to (iii) is at least 10:1. The compositions are used in cosmetics and pharmaceuticals and have broad anti-microbial activity, in particular against, at active contents of only about 3 wt. %.

Antimicrobially active compositions based on zinc compound, glycerine monoalkyl ether and antioxidant

A stabilizer composition having (a) one or more 1- or 2-(C- to C-alkyl) glycerol ethers (glycerol monoalkyl ethers) and (b) a mixture of at least two different aromatic alcohols (b1, b2) chosen from the groups of i) aryloxyalkanols, ii) arylalkanols and iii) oligoalkanol aryl ethers, where the two different aromatic alcohols belong to different groups i), ii) and iii).

Stabilize compositions based on monoalkyl glycerol ethers and aromatic alcohols

A preservative which comprises a) one or more isothiazolones and b) one or more glycerol monoalkyl ethers, and the use of the preservative for microbicidal finishing of cosmetic and pharmaceutical products.

Isothiazolone-containing preservative with improved effectiveness

The invention relates to a preservative which 5 comprises a) one or more isothiazolones and b) one or more glycerol monoalkyl ethers, to the use of the preservatives for microbicidal finishing of cosmetic and pharmaceutical products, and to corresponding microbicidally finished products.

The invention relates to a preservative comprising at least one isothiazolone, at least one quaternary ammonium compound, and at least one stabilizer selected from the group of sulphite salts, hydrogen sulphite salts, sulphite-releasing compounds and hydrogen-sulphite-releasing compounds, the presence of algicidal triazine being ruled out. The preservative inhibits the growth of fungi, algae and bacteria on or in alkaline coating compositions. The invention furthermore relates to a process for the preparation of the preservative, to its use in a coating composition, and to the preserved composition.
