This invention provides a formulation and preparation method for an exosome-based skin medication. Taking the preparation of a 100g finished formulation as an example, it consists of active ingredients, a nanogel carrier, a composite stabilizer, a moisturizer, a pH adjuster, a preservative, and deionized water. By constructing a nanogel sustained-release system adapted to exosomes and a composite protection mechanism, the exosomes are stably and slowly released and efficiently absorbed on the skin surface within 7 days. This solves the problems of rapid release, low utilization rate, poor stability, and frequent reapplication required for exosome-based skin medications, thereby improving the skin care and treatment effects of exosomes.

The invention relates to hard film anti-rust oil and a preparation method thereof. The hard film anti-rust oil comprises the following raw materials: base oil, a film-forming agent, a plasticizer and an anti-rust agent, the film-forming agent comprises rosin, and the plasticizer comprises dodecanol. The hard film anti-rust oil contains rosin and dodecanol at the same time, the rosin and the dodecanol are compounded, high adhesive force brought by polar groups of the rosin is reserved, the flowability of molecular chains is improved through long-chain alkyl of the dodecanol, and the bending performance is improved while the high adhesive force of a film layer is kept. In addition, conjugated double bonds in the rosin are easy to oxidize and yellow under the action of illumination and oxygen, so that the appearance of the film becomes poor; long-chain alkyl of dodecanol can wrap rosin molecules, contact between the rosin molecules and air and ultraviolet rays is reduced, and through an accelerated aging test, the yellowing degree of a mixed system is reduced to 3.2 or below from 8.5 of pure rosin.

The utility model discloses an oral ice stimulation cotton swab which comprises a packaging shell and a cotton swab body arranged in the packaging shell, the cotton swab body comprises a cotton head and a handle bar which are fixedly connected, and a first cavity used for containing the cotton head and a second cavity used for containing the handle bar are arranged in the packaging shell; a liquid storage bag is connected to the end, away from the second cavity, of the packaging shell, refrigerating fluid is arranged in the liquid storage bag, the liquid storage bag communicates with the first cavity through a channel, and a diaphragm is fixedly connected to the interior of the channel. The cotton swab body and the refrigerating fluid are integrated in the packaging shell together, the refrigerating fluid only needs to be squeezed into the first cavity and then frozen when the cotton swab is used, the number of needed objects is reduced, the manufacturing process is simplified, carrying is convenient, meanwhile, the packaging shell is good in sealing performance, the hygiene of the cotton swab body is improved, the cotton swab body is independently placed in the packaging shell, and the packaging shell is convenient to carry. And no adhesion phenomenon occurs after freezing.

An organic polysiloxane-modified cyclodextrin compound composed of a sugar unit represented by the following formula (1) [in the formula, R is a hydrogen atom, a group represented by the following formula (2) (in the formula, R 1 is a group selected from an alkyl group having 1 to 8 carbon atoms, a fluorine-substituted alkyl group having 1 to 8 carbon atoms, and an aryl group having 6 to 12 carbon atoms, n is an integer of 1 to 10, and a is an integer of 0 to 3], or a group represented by the following formula (3) (in the formula, X is a divalent organic group, and * is a bonding end that bonds with a hydroxyl group of another sugar unit]. The ratio of the number of moles N H of hydrogen atoms, the number of moles N S of the group represented by the above formula (2), and the number of moles N L of the group represented by the above formula (3) is N H :N S :N L = 0.5 to 2.5: 0.3 to 2.0: 0.1 to 0.5, N H +N S +N L = 3.0.

The utility model discloses an integral type peanut seeding and fertilizing device relates to peanut seeding and fertilizing technical field, including the vehicle body, the positive surface of vehicle body is connected with the fixing frame, and the positive surface installation of fixing frame has the first storage tank, the bottom of first storage tank is connected with the first discharge pipe, and the inside movable joint of first discharge pipe has the first valve post, the surface of first valve post is equipped with the first reservation groove, and one end of first valve post is connected with second connecting rod. In the utility model, through the setting of first storage tank, second storage tank, discharge pipe etc.

The utility model discloses a film cutting device for PE protective film processing, and relates to the field of PE film processing, the film cutting device comprises a cutting panel, a plurality of sliding rods are fixed on both sides of the middle part of the top end of the cutting panel, a lifting pressing plate is in sliding fit with the plurality of sliding rods, a cutting groove is formed in the top end of the lifting pressing plate along the length direction, and the top end of the lifting pressing plate is provided with a clamping groove. A sliding groove is formed in the top end of the cutting panel in the length direction, a sliding block is arranged in the sliding groove in a sliding fit mode, after the trapezoidal sliding block completely passes through the lifting pressing plate, the lifting pressing plate loses pushing force and automatically descends to press the upper surface of the PE film, and the PE film can be cut by a cutter through the cutting groove. Due to the pressing effect of the lifting pressing plate on the PE film and adsorption of the sliding block at the bottom end of the PE film, the PE film can be tensioned through the generated pulling force, adhesion cannot be generated during cutting, meanwhile, the PE film can be automatically driven to advance through movement of the sliding block, and the situation that workers manually pull the PE film to conduct cutting work is reduced.

The present invention relates to a drying device for producing pancreatic trypsin, comprising a drying mechanism for drying material, a hot air mechanism for providing hot air for the drying mechanism, a spraying mechanism for dispersing the material in the drying mechanism, and a separating mechanism for collecting the product, wherein the drying mechanism has a drying cavity, the spraying mechanism has a nozzle extending into the drying cavity from the center of the top of the drying cavity, the hot air mechanism generates hot air entering the drying cavity from the middle of the drying cavity and flowing upwards along the inner wall of the upper part of the drying cavity to the top of the drying cavity and then downwards, the hot air contacts the liquid droplets sprayed by the spraying mechanism to rapidly evaporate the water in the liquid droplets, and the dried material is carried into the separating mechanism by the hot air, the air is discharged by an exhaust pipe, and the product remains in the separating mechanism. The present invention has the effects of not adhering to the inner wall, improving product quality and production efficiency.

[Problem] For a sheet-shaped cosmetic, it is possible to contain a salt-type whitening agent without reducing the viscosity of a base, it does not drip even if it is attached to the skin, the sticky feeling after peeling off the sheet is excellent, and although the sheet has high adhesion to the skin, it is not sticky after peeling off. [Solution] A sheet-shaped cosmetic is obtained by impregnating a nonwoven fabric with a base, the base containing at least (A) a hydrophobically modified polyether polyurethane and (B) a salt-type whitening agent.
