摘要

Antimicrobial compositions containing (i) at least one zinc compound selected from zinc salt and zinc oxide; (ii) at least one glycerine monoalkyl ether, R-O-CH2-CHOH-CH2O, wherein R is a branched or unbranched C1-C24 alkyl group that can be substituted with one or more hydroxy and/or C1-C4 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; 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 Pseudomonas aeruginosa, at active contents of only about 3 wt. %.
