A natural antibacterial and antiviral biological composition is provided for use in hospitals and homes, in particular a composition that includes ricinoleic acid derived from the extraction of castor oil, diethanolamine and propolis, a method for obtaining the composition, and the use thereof. The invention can be used to control various pathogenic microorganisms, such as bacteria belonging to the Staphylococcus, Pseudomonas, Enterobacter and Bacillus genera; as well as hospital-environment fungi (filamentous and yeast-like) and phytopathogenic fungi (Colletrotichum fragariae). The product can be sprayed on biotic and abiotic surfaces, and non-woven fabric can subsequently be used to remove organic matter, including microorganisms. The product can also be used to disinfect medical, dental and hospital items by immersion followed by quick rinsing.

Cyclodextrin compositions including one or more radiation polymerizable monomers and a cyclodextrin inclusion complex, the cyclodextrin inclusion complex including a cyclodextrin compound and an olefinic inhibitor of an ethylene generation in produce, are coated onto packaging materials and cured. Treated containers and treated package inserts having the cured cyclodextrin compositions are useful in packaging of respiring plant materials.

The present invention relates to novel synergistic compositions comprising known “clean-label” antimicrobial substances as well as processes for stabilizing food substances against typical food borne spoilage microorganisms and/or pathogens. It is a further object of the invention to provide novel combinations of “clean label” antimicrobials which may be employed in such a process.
