Methods and apparatus for drug delivery involving phase changing formulations
InactiveUS20020004063A1Cleanly peeled from the skinMaintenance of such surfaceSalicyclic acid active ingredientsAnaestheticsPharmaceutical formulationSoft solids
This invention relates to an apparatus and method of drug delivery on a human body surface. The formulation comprises a drug, a conversion agent capable of converting the formulation from a less solid phase to a coherent, soft, solid phase, and a vehicle medium or carrier for the drug and conversion agent. The drug formulation is applied to this human body surface in its less than solid phase and is subsequently converted to a soft solid phase while the drug is being delivered through the human body surface. After delivery of the drug is complete, the soft solid formulation can be removed or peeled from the body surface as a coherent solid formulation. The drug formulation provides control over drug delivery rates and allows the formulation to be removed without leaving a messy, residual formulation on the body surface.

A soft-solid ear piece is formed to fit the typical human ear canal and will self form to fill the ear cavity by having an internal structure, endoskeleton, or bladder to expand to precisely fit the ear piece securely and comfortably in the ear canal. This self forming ear piece will enable ready-ware and custom molded hearing aids, hearing protectors, audio ear pieces, cell phone ear pieces and assistive listening devices to fit comfortably, securely, and free of acoustic feedback in the external ear canal. It creates an acoustic seal to optimally reduce peripheral leakage and intermodulation distortion delivering excellent acoustic performance while keeping environmental sounds blocked out.

Process for the production of a deodorant or antiperspirant product
A deodorant or antiperspirant soft solid composition is filled into dispensing containers by injection moulding, i.e. under pressure, preferably in the vicinity of its normal setting temperature. The deodorant or antiperspirant composition is preferably continuously produced in a screw extruder, especially a twin screw extruder, controlled to deliver the composition in a suitably viscous state under low shear and particularly for formulations in which a particulate antiperspirant is suspended in a fluid carrier. The pressure in the injection head at the point of injection is greater than 120 kPa and in many instances from 800 to 2000 kPa. The combined process offers benefits for controlled fill of dispensing containers, particularly for formulations incorporating sensitive ingredients and offers tolerance in composition temperature at the time of fill.

Antiperspirant compositions
Soft solid antiperspirant formulations in which a particulate antiperspirant active material is suspended in a continuous phase containing a water-immiscible liquid which is structured by specified proportions of an organic polymeric thickener and a second structurant selected from fibre-forming structurants and waxes (often other than fatty alcohols) or a mixture of both.Such soft solid formulations avoid or minimise problems inherent in production of many published formulations such as sensitivity to small changes in concentration of the structurant.

Microfabricated rubber microscope using soft solid immersion lenses
Soft lithography with surface tension control is used to microfabricate extremely efficient solid immersion lenses (SILs) out of rubber elastomeric material for use in microscope type applications. In order to counteract the surface tension of the mold material in a negative mold that causes creep on a positive mold, material such as RTV is partially cured before use in order to allow the reticulation of polymer chains to change the viscosity of the uncured material in a controllable manner. In a specific embodiment, the techniques of soft lithography with surface tension control are used to make molded SILs out of the elastomer polydimethylsiloxane. The lenses achieve an NA in the range of 1.25. The principle of compound lens design is used to make the first compound solid immersion lens, which is corrected for higher light gathering ability and has a calculated NA=1.32. An important application of these lenses is integrated optics for microfluidic devices, specifically in a handheld rubber microscope for microfluidic flow cytometry.

Antiperspirant/deodorant active for no white residue sticks and soft solids
Antiperspirant actives that produce practically no visible white residue, even against a black background is provided by the reduction of the particle size, using a refractive index modifier, to a point where the antiperspirant active on application provides no discernible whiteness.When formulated into an antiperspirant stick, the antiperspirant actives produce an improved combination of functional properties, including excellent antiperspirancy, smooth skin feel, nontacky, quick drying and leave no visible residue.The exceptionally high surface area of the antiperspirant active results in rapid and efficient delivery of the active to the sweat glands and possible absorption. The absence or reduced quantity of suspending and flow enhancing agents, of gellant and surfactant, is believed to improve the antiperspirant active's ability to physically reach the sweat glands and improve efficacy.

Method for manufacturing antique wooden floor
The invention relates to a method for manufacturing an antique wooden floor, substantially comprising normal working procedures such as texture processing for the surface of a base material, tenons making at two sides, edge jetting, coloring and lacquering. The method is characterized in that: the texture processing for the surface of the base material is an overlay technology that the surface of the base material is pressed into hand-scrapped antique wooden textures with an antique wooden-shaped molding board and a hot pressing machine. The overlay technology that the surface of the base material comprises the specific steps of sorting, sanding, installing a crash pad and the antique wooden-shaped molding board, adjusting technical parameters of hot pressing temperature and hot pressing pressure of the pressing machine, emptying, pressing and shaping, discharging, balancing and staying for 3 days, and then coloring. The method for manufacturing the antique wooden floor has the beneficial effects of canceling traditional abrasion resistant papers and balance papers, directly pressing high-density boards to have the effect of antique wooden texture by the pressing machine; and pressing the antique effect on soft solid wood. The surface of the solid wood composite board base material is pressed into antique wooden effect and scraped into the antique wooden effect and then is lagged, which replaces traditional inefficient method for directly hand-scrapping the solid wood composite floor into the antique floor.
