5 results about "Anhydrous lanolin" patented technology

This application relates to the field of veterinary drug technology, and discloses a transdermal absorption-enhancing ointment and its preparation process. The ointment components include white petrolatum, anhydrous lanolin, caprylic / capric triglycerides, hydrophobic fumed silica, and a highly fluid active permeation-enhancing phase. The permeation-enhancing phase contains active drugs and soybean lecithin, which self-assemble to form an inverse micelle aggregate. Soybean lecithin cross-links with the silanol groups on the surface of silica to form an intermolecular hydrogen bond network, constructing a sterically hindered framework within a continuous lipid matrix to prevent the polar drug-loaded phase from permeating and separating upon heating. Simultaneously, the inverse micelle structure effectively improves the transdermal absorption rate of the drug. The preparation process controls the lipid crystallization kinetics through slow cooling under negative pressure and micro-shear dynamic rheology. This invention solves the problems of easy precipitation upon heating, low transdermal efficiency, and poor rheological properties in traditional ointments, resulting in a product with a stable physical structure and good pseudoplastic texture.

This utility model discloses a filtration device for the extract of anhydrous lanolin production, belonging to the technical field of filtration devices for anhydrous lanolin production. It includes: a vertical leaf filter; and an annular manifold surrounding the vertical leaf filter, connected to the inlet pipe of the vertical leaf filter, with a liquid pump installed on the inlet pipe. The utility model connects to the supply pipe for scouring wastewater via a pipe joint. The scouring wastewater enters a settling tank through a first pipe and settles, where deposited impurities are located below the coarse filtration channel. The second pipe is alternately opened, allowing scouring wastewater with remaining floating impurities to enter the coarse filtration channel for coarse filtration before entering the annular manifold for further filtration. Natural sedimentation and level difference are used to achieve settling and pre-filtration of the scouring wastewater. Under the suction of the liquid pump, the scouring wastewater in the annular manifold enters the vertical leaf filter through the inlet pipe for fine filtration, resulting in good filtration effect and high filtration efficiency.

This utility model discloses a tube filling device for anhydrous lanolin, belonging to the technical field of anhydrous lanolin filling devices. It includes: a filling machine body with a support platform on one side; a positioning sleeve fixedly connected to the support platform, aligned with the filling valve of the filling machine body, and having a clearance groove; and two telescopic cylinders symmetrically arranged and fixedly connected to the filling machine body. The utility model involves placing a tube package into the positioning sleeve, and the filling valve injecting anhydrous lanolin from the filling machine body into the tube package. The telescopic cylinders extend, allowing an ultrasonic welding mold to act on the tube package through the clearance groove. The ultrasonic waves generated by the ultrasonic generator are converted into high-frequency vibration mechanical energy on the ultrasonic welding mold, thereby sealing and trimming the burrs on the tube package. This eliminates the need for separate welding and burr trimming operations after filling, making the tube filling operation convenient.

This utility model discloses a distillation apparatus for anhydrous lanolin, comprising a condenser shell, an upper air inlet cover mounted on the top of the condenser shell, a delivery pump disposed on one side of the condenser shell, and an electrically heated gas delivery pipe installed at the exhaust end of the delivery pump. The end of the electrically heated gas delivery pipe away from the delivery pump is connected to the air inlet end of the upper air inlet cover. A liquid collecting cylinder is installed at the bottom of the condenser shell, and a drain pipe is installed at the bottom of the liquid collecting cylinder. In this utility model, the delivery pump delivers lanolin vapor generated by evaporation in the heating pot into the upper air inlet cover of the condenser shell through the electrically heated gas delivery pipe. The upper air inlet cover allows the lanolin vapor to enter the tube bundle condenser tube assembly. The coolant in the condenser shell cools and condenses the lanolin vapor in the tube bundle condenser tubes. The condensed liquid is discharged to the next stage of distillation through the liquid collecting cylinder and the drain pipe.
