A droplet for delivering oral hygiene to a user can be provided. The droplet can include a dissolvable outer membrane that defines a volume with oral hygiene inside the volume. The outer membrane can be formed from dissolvable film strip technology that dissolves upon contact with water. In one aspect of this embodiment, the outer membrane of the droplet can form a flying saucer-like shape. In one aspect of this embodiment, the outer membrane of the droplet can form a pillow-like shape. In one aspect of this embodiment, the droplet further can include a logo, a cartoon character, a word or the like printed on the outer membrane.

The invention discloses an eyelash liquid eyeliner, wherein the raw materials comprise the following components in parts by weight: 50-60 parts of ethyl hexyl acrylate copolymer, 30-40 natural beeswax, 10-12 carnauba wax, 8-12 polyvinylpyrrolidone, 5-7 shellac, 1-3 black talc powder, 20-30 polyvinyl alcohol, 20-30 of silicone resins, 10-12 of codariocalyx motorius saponin extract, 5-7 dual-directional regulation growth promotion factors, 1-3 antifreeze, 1-3 coloring agent, 1-3 preservative, and 5-7 antioxidant. Components in the liquid eyeliner are replaced with natural substances of the natural beeswax, the carnauba wax, the shellac and the like, and the eyelash liquid eyeliner is safe to skin. Besides, organic silicone resins are added, so that the condition that the eyelash liquid eyeliner is broken up when being in contact with water can be effectively avoided, the organic silicone resin can effectively block ultraviolet rays and prevent the ultraviolet rays from destroying roots of eyelashes.

A composition suitable for application as a nail polish, the composition comprising: an alcohol solvent; ethylcellulose, in an amount that is about 1.0% by weight of the final composition; a film forming agent that includes maleic acid monobutyl ester-vinyl methyl ether copolymer, and maleic acid monoethyl ester-vinyl methyl ether copolymer, in an amount that is at least 40% by weight of the final composition; isostearyl alcohol, in an amount that is about 3.0% by weight of the final composition; a plasticizer in the form of a citric acid ester, in art amount that is about 1.0% by weight of the final composition; a colorant and a fragrance. This composition is suitable for application to a human nail.

A skin printing solution system includes a skin printing device that provides a user with a skin printing solution user interface including an online art gallery, a skin printing server that provides the online art gallery to the skin printing device, and a skin printer that outputs a tattoo image received from the skin printing device to a print region. Herein, when the user selects a tattoo image through the skin printing solution user interface, the skin printing device receives the selected tattoo image from the skin printing server and transmits the received tattoo image to the skin printer. In addition, the online art gallery includes multiple tattoo images, and the print region is the skin of the user or a different user.

Provided is a method for producing a coating film on the skin by electrostatic spraying, the coating film having excellent appearance and excellent scratch resistance and stretch resistance.

A method for producing a coating film on skin, comprising the steps of: A) electrostatically spraying a composition X comprising a component (a) and a component (b) directly to the skin to form a coating film on a surface of the skin: (a) one or more volatile substances selected from the group consisting of water, an alcohol and a ketone; (b) a film-forming polymer; and B) applying a composition Y comprising a component (c) and a component (d) to the skin: (c) 0.3% by mass or more and 10% by mass or less of a water-soluble polymer; (d) 40% by mass or more and 95% by mass or less of water
in the order presented or in reverse order.

A solid temporal colorimetric hydrogel cosmetic composition includes 15 to 99.90 wt % of the water phase part and 0.10 to 85 wt % of the oil phase part, having a refractive index difference of 0 to 0.02 therebetween, and having a color change according to variations in a refractive index difference between the water phase part and the oil phase difference when applied to the skin. The cosmetic composition not only has flexibility through irradiation of gamma-rays, but also enables an optimal application time of the cosmetic composition to be visually confirmed through a color change from transparency to ivory white due to a change in the refractive index difference caused by absorbency and volatilization of water when applying the composition to the skin. The cosmetic composition is capable of improving quality of a product although a preservative irritating to the skin is not added.

Disclosed herein are oral care compositions comprising: an orally acceptable vehicle comprising greater than about 50 wt. % water; and a preservative system comprising: benzyl alcohol, benzoic acid or a salt of benzoic acid; and an alkylene glycol. Methods of making and using these compositions are also described herein.
