US Classification:
514738
Abstract:
What is described herein are antimicrobial compositions which are defined blends of a 1,2-diol and phenoxyethanol which show broad activity against bacteria, fungi and mold spores. This activity is potentiated by the addition thereto of small amounts of a co-biocide for which the blend acts as a delivery system for the otherwise water-insoluble co-biocide.

International Classification:
C07D26314
US Classification:
548238
Abstract:
What is described herein are polymerizable pyrrolidonyl 4,5-unsubstituted oxazoline monomers, homopolymers thereof, and copolymers with other monomers. A preferred polymerizable monomer compound is 2-(1-methyl-2-pyrrolidon-4-yl)-2-oxazoline. The polymers herein have excellent hydrotropic properties thus increasing the water solubility of organic compounds previously considered as water insoluble, and exhibit complexation with water soluble cosolutes.
