ABSTRACT:
Films and coatings formed from a specified class of organosiloxane/urethane copolymers are unique by virtue of their high permeability to volatile ingredients in the form of aqueous compositions and their inertness to the ingredients of these compositions. Containers wherein at least a portion of the walls comprise films or coatings formed from these copolymers are used to achieve the controlled release of volatile fragrances and biologically active agents from aqueous compositions confined within the container into the adjacent atmosphere.
