Patent

CA 2723024

Anti-microbial compositions are provided which comprise as an antimicrobial agent at least one compound derived from a select polyol containing at least 3 hydroxy groups wherein one or more, and often two or more, of the hydroxyls are derivitized to form certain ether, ester, carbonate or carbamate groups which groups may bear additional functionality. Antimicrobial compounds of this class are also provided. The compositions are effective against a variety of pathogens including fungi, Gram positive bacteria and Gram negative bacteria and are expected to have low human toxicity. Applications for the polyglycerol antimicrobial agents and compositions include those involving human and plant contact, such as cosmetics, hair care products, textiles and plant protections, as well as in applications with much less human contact, such as plastics, coatings, wood, paper and other materials of construction.

L'invention concerne des compositions anti-microbiennes comprenant, en tant qu'agent anti-microbien, au moins un composé dérivé d'un polyol sélectionné contenant au moins trois groupes hydroxy, un ou plusieurs, et souvent, au moins deux de ces hydroxyles étant dérivés de manière à former des groupes éther, carbonate ou carbamate, lesquels groupes peuvent présenter une fonctionnalité supplémentaire. L'invention concerne également des nouveaux composés anti-microbiens de cette classe. Les compositions sont efficaces contre une large gamme de pathogènes parmi lesquels les champignons, les bactéries Gram positif et les bactéries Gram négatif et sont censées avoir peu d'effets toxiques sur l'être humain. Des applications de ces agents anti-microbiens polyglycérols et de ces compositions comprennent les applications impliquant le contact avec les plantes ou avec l'être humain, telles que les cosmétiques, les produits de soins capillaires, les textiles et les protections des plantes, ainsi que des applications impliquant beaucoup moins de contact avec l'être humain, telles que les plastiques, les enrobages, le bois, le papier et d'autres matériaux de construction.
