Novel burst-free, sustained release biocompatible and biodegrable microcapsules which can be
programmed to release their active core for variable durations ranging from 1-100 days in an
aqueous physiological environment. The microcapsules are comprised of a core of polypeptide or
other biologically active agent encapsulated in a matrix of poly(lactide/glycolide) copolymer
having a molar composition of lactide/glycolide from 90/10 to 40/60, which may contain a
pharmaceutically-acceptable adjuvant, as a blend of uncapped free carboxyl end group and endcapped
forms ranging to ratios from 100/0 to 1/99.
US Patent No: 6905674
Aqueous photoprotective compositions comprising acrylamido-2-methylpropanesulfonic acid polymers
and 4,4-diarylbutadiene UV-A sunscreens
Photoprotective compositions, e.g., oil-in-water or water-in-oil emulsions, well suited for the
photoprotection of the skin, lips and/or hair against the damaging effects of UV-radiation, comprise
at least one aqueous phase, at least one oily phase, at least one partially or completely neutralized,
crosslinked or non-crosslinked water-soluble or water-dispersible acrylamido-2methylpropanesulfonic
acid (AMPS) polymer and at least one UV radiation-screening system, said
at least one screening system comprising at least one 4,4-diarylbutadiene UV-A-screening agent
US Patent No: 6916465
Deodorizing preparations containing nanosacle chitosans and/or chitosan derivatives
A deodorizing composition containing an ingredient selected from the group consisting of a
nanoscale chitosan having a particle diameter of from about 1 to 300 nm, a nanoscale chitosan
derivative having a particle diameter of from about 1 to 300 nm, and mixtures thereof.
US Patent No: 6916872
Non-spherical nanopowder derived nanocomposites
Nanocomposites from nanofillers with preferred form of whiskers, rods, plates and fibers are
disclosed. The matrix composition described includes polymers, ceramics and metals. The
composition disclosed include inorganic, organic and metallic. These nanocomposites are useful in
wide range of applications given their unusual properties such as refractive index, transparency to
light, reflection characteristics, resistivity, permittivity, permeability, coercivity, B-H product,
magnetic hysteresis, breakdown voltage, skin depth, curie temperature, dissipation factor, work
