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. Novel 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 anti-microbial 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.

The present invention relates to the discovery of biodegradable multi-armed oligomers wherein the end groups of these oligomers have been functionalized with biologically active molecules. The resultant multi-armed oligomers end-functionalized with biologically active molecules have a controllable degradation profile. The hydrolytic degradation of oligomers of the present invention releases the biologically active compound as such with no change in native chemical structure.
