A brush tip for a cosmetic applicator which is hygienic by preventing the growth of bacteria and other germs in the area of the brush tip not impregnated with the application fluid, as well as the manufacturing method of the brush tip and a cosmetic applicator using the brush tip. This brush tip for a cosmetic applicator includes brush tip filaments and serving as an applying part of the cosmetic applicator having a cosmetic storage for storing a cosmetic fluid, with the rear end of the brush tip attached to the front end of the cosmetic storage. The brush tip incorporates a discharge port that communicates with the cosmetic storage of the cosmetic applicator, and a coating of an antimicrobial agent is formed on the surface of the brush tip filaments, located behind the discharge port inside the brush tip.

A liquid applicatoris provided with a liquid pressing mechanism (liquid pressing means)for pressurizing an application liquidwithin a main body, and supplies an applying partat a front end of the main body with the application liquidby pressing of the liquid pressing mechanism, wherein the applying partis made of an elastic material, is formed with a communication channelfor connecting inside and outside of the main body, and is provided with an application portionso as to further protrude to the front side from an ejection portof the communication channel, and in the application portion, a portion 3 (mm) from a front end thereof has a vertical-direction repulsion force of 0.01 to 1.40 (N), resulting that it is possible to provide a liquid applicator with an appropriate hardness and bending elastic force, having no application unevenness and good application characteristics.

Liquid applicator

A liquid applicator includes a liquid pressing mechanismfor pressurizing an application liquidinside a main bodyso as to supply the application liquid to an applying memberat the front end by the pressing of liquid pressing mechanism, wherein the applying memberis made of an elastic material, has a valve structurewhich is formed with a communication pathfor communication between the inside and outside of main bodyand can close the communication pathby elasticity in the normal condition and open the communication pathby elastic deformation of the communication path when the application liquid is pressurized by liquid pressing mechanism, and, an ejection openingof communication pathof valve structureis arranged to front onto the applying portionof the applying member

In order to provide an accumulatively dying hair color of a hair manicure type which does not require washing of hair immediately after used and by which hair are gradually dyed by repeating use thereof as a temporary coloring material, used is a hair color comprising 0.1 to 3% by weight of at least one of water-soluble dyes, 1.5 to 10% by weight of a nonionic or anionic silicone base resin, 0.1 to 1.5% by weight of an amphoteric acryl resin, 3 to 20% by weight of a hair dying auxiliary, 30 to 80% by weight of a lower alcohol and 5 to 50% by weight of water and having a pH controlled to 2 to 5.

Hair color

Provided is a hair dye comprising 0.1 to 3.0% by weight of at least one of aqueous acid dyes and a resin comprising a terpolymer constituted from a vinyl cyclic amide, an acrylic acid derivative and a quaternary derivative of acrylic acid, wherein a content of the resin is 0.1 to 2.5% by weight in terms of a solid content; and the hair dye further comprises 1.0 to 20% by weight of a hair dyeing auxiliary agent, 20 to 60% by weight of a lower alcohol and 20 to 60% by weight of water and has a pH of 2 to 4.

Hair dye and applicator for hair using the same

A hair color which includes 0.5 to 8% by weight of a basic dye as a coloring agent, 0.5 to 15% by weight of a alcohol-soluble resin, 20 to 80% by weight of lower alcohol and 5 to 50% by weight of water. The hair color does not require washing of the hair immediately after being applied and enables the hair to be gradually dyed upon repeated use. The hair color can provide excellent water resistance against sweat and rain in a hot and humid period such as a summer season.

An applicator includes: a barrel cylinder; an application portion in front of the barrel cylinder; a tank placed behind the application portion for storing liquid inside the barrel cylinder; a pipe (conduit) for conducting the liquid ejected from the tank to the application portion; a piston which is fitted in the tank as to slide in the axial direction ensuring a watertight contact; and a liquid pushing device placed in the rear part of the barrel cylinder for pushing the liquid from the tank to the application portion via the pipe by moving the piston forwards. In this applicator, the bore of the pipe is set between 0.2 mm and 1.7 mm, and the viscosity of the liquid measured by the E-type viscometer within an temperature range for operation is set between 20 mpa.sec and 100,000 mpa.sec. Further, the barrel cylinder is formed of PP, and the piston is formed of HDPE or LLDPE.

The present invention provides a temporary hairdye which is excellent in dispersion stability of a pigment even after storage over a long period of time by dispersing titanium black, which is safe to a human body, in alcohol having 4 or less carbon atoms, primarily ethanol by using an N-methacryloylethyl-N,N-dimethylammonium..alpha.-N-methylcarboxybetain.but yl methacrylate copolymer. Further, there can be prepared a temporary hairdye which increases dispersion stability of the pigments and provides a different hue by subjecting titanium black and other pigments, particularly iron oxide type pigments such as iron oxide red, black iron oxide and yellow iron oxide to dispersion treatment together.

The present invention provides a teeth-coating liquid comprising a color pigment represented by titanium oxide and a pearl pigment or an extender pigment represented by tricalcium phosphate, dispersed singly or in combination thereof in an alcohol series solvent, mainly ethanol with an N-methacryloylethyl-N,N-dimethylammonium..alpha.-N-methylcarboxybetaine.bu tyl methacrylate copolymer, and an applicator for the coating liquid described above. This teeth-coating liquid provides excellent dispersion stability, gloss, coating property and sticking performance by using the N-methacryloylethyl-N,N-dimethylammonium..alpha.-N-methylcarboxybetaine.bu tyl methacrylate copolymer singly or in combination with a shellac and a vinyl acetate resin.

Teeth coating liquid

An applicator for applying a fluid such as eye shadow. The applicator comprises a tubular core having a conduit, and a porous outer membrane arranged to cover the tip of the tubular core. The outlet of the conduit, of the tubular core is formed so that the outlet opens in the tubular core on one side of the tubular core from the longitudinal axis of the tubular core. Therefore, it is possible to apply a fluid to a surface, such a skin of a human being, by using one side of the applicator through which the fluid easily soaks, and to spread and gradate the fluid on the surface, by using the other side of the applicator. The outer membrane may be made from two or three porous sheet members having different porosities from each other, so that a fluid easily soaks through one of the porous sheet members having a relatively large porosity.
