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.

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.

[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.
