Abstract: A foam made of a specific material having superior properties and cosmetic products including the foam are disclosed.

Abstract: Provided is a water-in-oil cosmetic composition comprising one or more thickening agents selected from the group consisting of sodium polyacrylate starch, polyacrylate crosspolymer-6, xanthan gum and locust bean gum in an inner phase. The water-in-oil cosmetic composition of the present invention brings improvements to time-related changes in preparation stability by means of inner phase thickening controlling the flow properties of an aqueous phase, and controls the size of emulsified particles by means of inner phase thickening, and as a result the invention has outstanding thixotropic characteristics and outstanding initial spreadability and has outstanding durability and, in addition, the invention provides both a fresh-cream-like soft feel in use and a liquid-like light feel in use.

Abstract: Provided is a polyether-based urethane foam for impregnating a cosmetic composition. The polyether-based urethane foam has excellent touch feel, portability and stability.

Abstract: The present invention provides a cosmetic product and a method for producing same, wherein the cosmetic product comprising a screen mesh includes: one or more materials selected from a group consisting of polyurethane, thermoplastic elastomer (TPE), polyester, polyether, acryl and olefin; and an absorbing material adjacent to the screen mesh. The cosmetic product of the present invention enables a user to appropriately adjust the degree of discharge of contents during use of the contents and to use the residual quantity of the carried contents as much as possible by means of the elasticity of the absorbing material. The cosmetic product of the present invention provides a wide variety of choices of absorbing materials compared with conventional cosmetics in which choices of absorbing materials are restricted by the types and pore sizes of the absorbing materials.

Abstract: The present invention provides a mascara container including: a pouch-shaped inner container of a film material; and an outer container of an elastic material that covers the outside of the inner container. According to the present invention, highly-viscous mascara content can easily be transferred to an application member when a user lightly squeezes a container, so that the residual mascara content inside the container can easily be discharged to increase the usable amount of content after the mascara is opened, regardless of the duration of use. Accordingly, the effect can be realized of improving eyelash volume by applying a sufficient amount of mascara content.

Abstract: The present invention provides a method for proposing personalized cosmetics and a system for implementing the same, the method comprising the steps of: photographing the visible spectrum of the skin of a subject to be measured; mapping a personalized visible spectrum to the measured visible spectrum of the skin so as to generate a spectral comparison table; matching a personalized composition to the spectral comparison table; and displaying the matched personalized composition on an image display unit.

Abstract: The present invention provides a high internal phase water-in-oil type cosmetic composition which shows colors by containing pearl particles or aqueous pigments in an internal phase. The present invention employs a particular kind of emulsifier forming large emulsification particles in order to allow the pearls or pigments to stably exist in an aqueous phase as an internal phase, and employs particular kinds of dispersant and preservative in order to supplement the emulsifying power for emulsion formation, prevent the separation of the formulation, and improve fluidity. In addition, in order to increase the degree of surface filling of the composition, silicone oil and ester oil are contained in an oil phase component as an external phase, and are mixed at a weight ratio in a suitable range. The cosmetic composition of the present invention provides the various aesthetic and functional effects of the pearls by stabilizing the pearls in the internal phase.
