JPH0965921A - Sponge puff for makeup - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a sponge puff for makeup in which a soft touch is obtained and stickiness and roughness is reduced by forming a siliconefilm by applying methyl hydrogen silicone oil or the like or its emulsion on the surface of a sponge as a base material, or by permeating it into the sponge. SOLUTION: In a sponge puff 1a, either methyl hydrogen silicone oil, silicone oil in which amino modified functional group, epoxy modified functional group, or the like is introduced, or reactive silicone oil which is hardened by catalyst or an emulsion of one of the silicone oil is either applied on the surface of a sponge 2 as a base material or penetrated into the sponge 2, thereby forming a silicone film 4. For example, the sponge 2 is dripped in amino modified silicone oil emulsion which is adjusted by adding 100 weight percent of water to 1 weight percent of the amino modified silicone oil, and the liquid is penetrated. The sponge 2 is dried at a temperature of 100 deg.C, and further fixed at a temperature of 150 deg.C, thereby forming the silicone film 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic sponge puff excellent in touch.

[0002]

2. Description of the Related Art Conventionally, as a foundation applying sponge, there are a sponge made of latex foam, a sponge made of closed-cell foam, and a sponge made of urethane sponge. In both cases, the base material is an elastomer, so that there is a "soft" feeling or a "sticky" feeling peculiar to the elastomer, and therefore there is a problem that the skin is pulled.

Among them, as a sponge for applying a liquid foundation, a sponge made of a closed-cell sponge is widely used by taking advantage of the fact that it does not suck a liquid.
Note that silicone modified EPDM and the like are often used as the material.

In the sponge puff 1c made of the base material sponge 2 having the closed cells 2e shown in FIG. 3, due to the high surface friction coefficient peculiar to the closed cell sponge, the cosmetic material 8 becomes the sponge puff 1c as shown in FIG. Although it slips well while it is in contact with the skin 9, as shown in FIG. 2, when the cosmetic 8 is applied to the skin 9 and dried, and the cosmetic 8 disappears between the sponge puff 1c and the skin 9, slippage occurs. There is a problem that it gives a so-called "soft" feeling of stopping, pulling on the skin and feeling pain. The arrow Z indicates the moving direction of the sponge puff 1c. In addition, there is a problem in that there is a feeling of “stickiness” when held by hand, which is disadvantageous in the initial feel evaluation.

In order to solve the above problems of the closed cell sponge puff, as shown in FIG. 4, a sponge puff 1d having an improved slidability is formed by coating spherical fine particle powder 3d on the surface of the closed cell base sponge 2. However, the application of the fine particle powder 3d causes a feeling of "roughness", which causes another problem of making a sound when touching the skin.

[0006]

The problem to be solved is that the conventional cosmetic sponge puffs 1c and 1d are
There is a feeling of “dryness” or “stickiness”, and the skin is pulled, or when it is held by the hand, there is a “stickiness” feeling, or a “gritty” feeling occurs, and there is a sound when touching the skin. The present invention is to provide a cosmetic sponge puff which has an unpleasant sensation such as erosion and the like, and which has solved the above problems and has an excellent feel.

[0007]

Means for Solving the Problems A cosmetic sponge puff 1a according to the invention of claim 1 is a silicone in which methylhydrogen silicone oil, amino-modified functional group, epoxy-modified functional group or the like is introduced on the surface of a base material sponge 2. The silicone film 4 is formed by applying or emulsifying an emulsion of any one of the above-mentioned silicone oils or any one of reactive silicone oils which are hardened by an oil or a catalyst.

The cosmetic sponge puff 1b according to the invention of claim 2
Is coated with particles 3b made of high-molecular-weight polyethylene or the like having a particle diameter of about several tens of microns on the surface of the base material sponge, and the surface of the base material sponge 2 fused by heating while maintaining the shape of the particles 3b is Hydrogen silicone oil, any of silicone oil having amino-modified functional group or epoxy-modified functional group introduced, reactive silicone oil that is hardened by a catalyst, or an emulsion of any of the above silicone oils is applied, or internally The silicone film 4 is formed by sufficiently penetrating into and hardening.

[0009] The invention of claim 3 provides the above-mentioned claim 1 or 2
In the above invention, the base material sponge is a closed cell sponge.

The material of the base material sponge 2 may be latex foam, closed cell sponge or urethane sponge. For example, acrylonitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), styrene butadiene rubber. (SB
R), natural rubber (NR), silicone rubber (Si), various sponge rubbers such as silicone modified EPDM, and synthetic resin foams such as polyethylene and vinyl acetate / ethylene copolymers.

Particles 3 attached to the surface of the base material sponge 2
Examples of the material of b are powders of various rubbers such as acrylonitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), styrene butadiene rubber (SBR), natural rubber (NR), silicone rubber (Si), and silicone modified EPDM. , Polyurethane, polyethylene, polypropylene, polyvinyl chloride, polyvinyl alcohol and vinyl acetate
Examples thereof include synthetic resin powders such as ethylene copolymers, organic powders such as walnut powders, and inorganic powders such as minerals.

In selecting the material of the particles 3b, it is necessary to study compatibility with the base material sponge 2 or compatibility with the intervening adhesive layer. In addition, it is necessary to consider hygienic safety for the skin. The base material sponge 2 that has been subjected to the above treatment is subjected to finishing treatment such as punching and polishing to obtain a final shape, but it may be performed before the above treatment, if necessary.
