摘要:
Systems and methods for electrospinning of core-sheath fibers are provided. The systems and methods achieve optimization of a shear stress that exists at a fluid boundary between core and sheath polymer solutions, by varying certain parameters of an electrospinning apparatus and/or the solutions used therewith.
摘要:
Implants and methods for the delivery of a therapeutic agent to a target location within a patient's body are disclosed. The implants include a fiber comprising a polymeric material and having a diameter of up to about twenty microns, and a first therapeutic agent within the fiber. The therapeutic agent is substantially in particulate form. The implants are of a variety of configurations, such as individual fibers, yarns, ropes, tubes, and patches.
摘要:
Medical implants and methods useful in treating postoperative pain are described. The implants comprise one or more electrospun drug-loaded fibers, which fibers comprise a drug useful in the treatment of pain. The implants are implanted at sites of interest including joint capsules, bones, and subcutaneous spaces, and are secured with tissue flaps or fasteners.
摘要:
Disclosed are fiber composite structures comprising a matrix material and at least one polymeric fiber in contact with the matrix material. The fiber(s) are preferably characterized by a diameter of up to about 20 microns. In certain embodiments, the fiber(s) comprise a therapeutic agent in an amount that exceeds the solubility limit of the therapeutic agent in the fiber polymer. In some embodiments, the fiber(s) comprise an inner radial portion and an outer radial portion.
摘要:
A base composition is provided which comprises water and a non-ionic surfactant mixture. The base composition is suitable for use in preparing a personal care product.
摘要:
The present invention relates generally to the field of electrospinning. In particular, the present invention relates to an electrospinning device that includes a slit-fixture defined by an elongate aperture disposed between opposing elements of an electrically conductive material. These elements include a variety of patterns/shapes that affect the flow of fluid through the aperture and the electrical field across the aperture.
摘要:
The present invention relates to beauty wash bar compositions which deliver enhanced visual benefits to the skin with specific optical attributes. This is accomplished using specific deposition systems (where oil/emollient comprises part of deposition system) and/or by ensuring dispersion of particles onto skin.
摘要:
The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced deposition of hydrophilic benefit agents carried on, trapped within or in the presence of the structured benefit agent.
摘要:
The present invention relates to compositions comprising a structured benefit agent pre-mix or delivery vehicle comprising benefit agent structured with crystalline materials, as defined, which when separately prepared and combined after preparation, provides enhanced delivery of benefit agent from a personal product bar carrying composition into which the premix is added. The use of structured benefit agent also enhances delivery of separate benefit agents in the premix (which may or may not be structured) and of separate benefit agents added separately from the premix.
摘要:
The present invention relates generally to the field of electrospun fibers. In particular, the present invention relates to core-sheath fibers and related electrospinning methods. The fibers of the invention comprise poorly water soluble drugs and/or proteins.
