  • Publication number: 20150056461
    Abstract: A film formed from a water-soluble polymer matrix containing a fragrance is provided. The film is water-sensitive so that upon contact with a sufficient amount of water, the matrix loses its integrity to increasingly expose the fragrance to the ambient environment for releasing its odor. The ability to incorporate a fragrance into the matrix is achieved by controlling the nature of the fragrance and polymer, the manner in which the matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the polymer to avoid the costly, time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch. Furthermore, to balance the fragrance's ability to release the desired odor during use while minimizing the premature exhaustion of the odor during processing, the fragrance has a boiling point (at atmospheric pressure) of from about 125° C. to about 350° C.

  • Patent number: 8759279
    Abstract: A film formed from a biodegradable polymer matrix within which is contained at least one fragrance is provided. The ability to incorporate a fragrance into the polymer matrix is achieved in the present invention by controlling a variety of aspects of the film construction, including the nature of the fragrance, the nature of the biodegradable polymer, the manner in which the polymer matrix and fragrance are melt processed, etc. For example, the fragrance may be injected directly into the extruder and melt blended with the biodegradable polymer. In this manner, the costly and time-consuming steps of pre-encapsulation or pre-compounding of the fragrance into a masterbatch are not required. Furthermore, to obtain a balance between the ability of the fragrance to release the desired odor during use and likewise to minimize the premature exhaustion of the odor during melt processing, the fragrance is selected to have a boiling point (at atmospheric pressure) within a certain range, such as from about 125° C.

  • Patent number: 6802895
    Abstract: Non-thermoplastic starch fibers having no melting point and having apparent peak wet tensile stress greater than about 0.2 MegaPascals (MPa). The fibers can be manufactured from a composition comprising a modified starch and a cross-linking agent. The composition can have a shear viscosity from about 1 Pascal·Seconds to about 80 Pascal·Seconds and an apparent extensional viscosity in the range of from about 150 Pascal·Seconds to about 13,000 Pascal·Seconds. The composition can comprise from about 50% to about 75% by weight of a modified starch; from about 0.1% to about 10% by weight of an aldehyde cross-linking agent; and from about 25% to about 50% by weight of water. Prior to cross-linking, the modified starch can have a weight average molecular weight greater than about 100,000 g/mol.

  • Patent number: 6656984
    Abstract: The invention relates to a hydrophobic polymer dispersion and a solvent-free process for the preparation thereof. According to the invention, the dispersion contains starch ester together with dispersion admixtures known as such. According to the process, the polymer is first mixed with a plasticizer in order to obtain a plasticized polymer blend. The plasticized polymer blend is then mixed with dispersion admixtures and water at an elevated temperature so as to form a dispersion. The plasticizing of the polymer and the dispersion of the mixture in water can be performed in an extruder. The obtained dispersion is homogenized in order to improve its stability. The dispersion obtained by the invention can be used to coat paper or board, as a primer or a component in paint or labeling adhesives, and it is also suitable for the production of cast films and as a binder in materials based on cellulose fibers, as well as for coating medicinal preparations.
