The invention discloses a moisturizing and repairing matte lipstick and a preparation method thereof in the field of cosmetics. The lipstick comprises a polydimethylsiloxane vinyl polydimethylsiloxane cross-linked polymer, two novel modified compounds, namely a silica supported titanium complex pigment anchoring agent and amphiphilic block polyamide microspheres, jojoba oil, caprylic / capric triglyceride, isononyl isononanoate, hydrogenated polydecene, a colorant, namely titanium dioxide iron oxide red iron oxide yellow, and a colorant, namely silica supported titanium complex pigment anchoring agent, amphiphilic block polyamide microspheres, jojoba oil, caprylic / capric triglyceride, isononyl isononanoate and hydrogenated polydecene. The anti-aging agent is prepared from mica, tocopherol, ascorbyl palmitate, butylated hydroxytoluene, vanillin and carnauba wax microcrystalline wax ozokerite. Wherein the silica supported titanium complex pigment anchoring agent is prepared by step-by-step reaction of titanium silicalite, titanate and stearic acid, and the amphiphilic block polyamide microspheres are formed by amidation polycondensation of dimethyl acetone diformate and amino polydimethylsiloxane. The lipstick ingeniously solves the contradiction between the matt makeup effect and the moisturizing and repairing performance, and has the remarkable advantages of being durable in color, comfortable in skin feeling and capable of fading cheilogramma.

The application relates to the technical field of veterinary drugs, in particular to a terbinafine hydrochloride tablet and a preparation method thereof. The terbinafine hydrochloride tablet comprises the following components in parts by weight: 10-20 parts of terbinafine hydrochloride, 60-80 parts of a filling agent, 10-20 parts of a binding agent, 0.05-0.2 parts of a lubricant and 0.2-0.4 parts of component A, wherein the component A comprises yellow iron oxide. The terbinafine hydrochloride tablet provided by the application has the advantages of simple preparation process, good stability and good application prospect. Further, the application further provides a preparation method of the terbinafine hydrochloride tablet. The terbinafine hydrochloride tablet is efficiently and stably prepared through several steps of pretreatment, wet granulation, whole-granulation and tablet pressing, and the process is simple and applicable.

This utility model relates to the field of iron oxide yellow production technology, and discloses a feeding device for producing low-sulfur iron oxide yellow. The device includes a support frame, a weighing mechanism on the inner side of the support frame, a pad at the bottom of the support frame, and multiple support legs fixedly connected to the top left side of the pad. The tops of the multiple support legs are fixedly connected to the same storage tank, and the storage tank has an anti-blocking mechanism inside. The weighing mechanism includes a fulcrum rod, which is fixedly connected to the middle of the inner side of the support frame. A balance rod is rotatably connected to the outer wall of the fulcrum rod. In this utility model, when the weights at both ends of the balance rod are equal, a trigger switch is activated to close the electric valve, and cylinder two is activated, causing the balance rod to rotate 90 degrees. Subsequently, cylinder one is activated to push the moving block to slide, causing the opening and closing plate to move to both sides of the material container, allowing the material inside the container to fall downwards, thus achieving a quantitative feeding process.

The invention is applied to the technical field of pharmaceutic adjuvants, and discloses a multi-effect synergistic innovative coating material which comprises the following components in percentage by weight: 13%-26% of hydroxypropyl methylcellulose, 10%-16% of polyethylene glycol, 0.07%-0.15% of dimeticone, 15%-21% of titanium dioxide, 38%-46% of talcum powder, 3.5%-7.6% of ethyl acrylate-methacrylic acid copolymer aqueous dispersion, 0.7%-2.0% of iron oxide red and 0.6%-1.05% of iron oxide yellow. According to the multi-effect synergistic innovative coating material, synergistic optimization of functions of film forming, shading, moisture prevention, drug release regulation, adhesion resistance, defoaming and the like is achieved by precisely regulating the proportion of all the components, a composite film forming system is formed by hydroxypropyl methylcellulose and an ethyl acrylate-methacrylic acid copolymer aqueous dispersion, the film forming effect is synergistically achieved, and the coating material has the advantages that the coating material has a good application prospect. The compactness of the coating layer is ensured, and the acid resistance and the stability of the coating layer are improved.
