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.

A disposable toothbrush having a toothpaste composition distributed over the bristles of the toothbrush without the use of metal graft initiators and catalysts, and in which the toothpaste and the flavoring is maintained for an extended period of time.

Disclosed is a system and method for the delivery, into interdental spaces, of oral care active agents contained in particles. The particles are made of one or more superabsorbent polymers (SAP), and are of size generally small enough to be easily applied into an interdental space. To this end, the particles typically have a length of below 1.5 mm. By virtue of the SAP's ability of absorbing several times its own weight in water, the particles will swell once in contact with saliva. As a result, the volume of the particles as applied in between teeth increases by at least eight times, thereby effectively making the particles larger than the average interdental gap size. The particles, once swollen, are thus held more firmly between the walls of the interdental space, thus preventing them from being easily washed away.

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.

Oral care compositions and/or unit-dose oral care compositions comprising a high level of surfactant. Oral care compositions and/or unit-dose oral care compositions with a high foaming efficiency. Oral care compositions and/or unit-dose oral care compositions with one or more web forming materials, one or more surfactants, and a sugar alcohol.

A method for lightening skin tone is provided, comprising topically administering a personal care composition comprising: (A) voided latex particles comprising (i) a core polymer comprising (a) 20 to 60 weight % of monoethylenically unsaturated monomers containing a carboxylic acid group, and (b) 40 to 80 weight % of non-ionic ethylenically unsaturated monomers; and (ii) a shell polymer comprising (a) 55 to 85 weight % of non-ionic ethylenically unsaturated monomers, and (b) 15 to 45 weight % of polyethylenically unsaturated monomers; (B) 0.1 to 10 weight % of pigment grade inorganic metal oxide particles having a particle size of 250 nm to 1,000 nm; (C) a dermatologically acceptable carrier; and (D) an emollient, wherein the voided latex particles are present in at 0.5 to 10 weight %, based on weight of the composition, contain a void and have a particle size of 400 nm to 1500 nm.

A topical composition comprising a Polymer, a high molecular weight hyaluronic acid (HWM HA) and/or its salt, a low molecular weight hyaluronic acid (LWM HA) and/or its salt, and a polyamino acid and/or its salt; and water and a method for identifying a test polymer that forms a micro-mesh structure when combined with such ingredients.

The present invention relates to self-assembly type Janus microparticles and a preparation method therefor. The present invention can be used for preparing Janus microparticles in which a degree of phase separation is precisely controlled, for realizing stable interfacial orientation by selectively coating only one side of particles with a metal oxide, and for mass-producing Janus microparticles which have a degree of phase separation precisely controlled and exhibit extreme amphiphilicity in an anisotropic structure. Therefore, the Janus microparticles and the preparation method therefor according to the present invention can be widely used in various fields, thus contributing to industrial development.

A hot wax composition useful in removing hair from skin contains an effective amount of a thermally activated pigment which causes the composition to change color when it is heated sufficiently for use in hair removal and then change color again when the composition has cooled enough to be removed.
