Description

  The present invention relates to a water-based solid cosmetic, and more specifically, in a cosmetic having a fresh feel and high glitter, stretches without a foreign body feeling, excellent uniformity of the cosmetic film, and elasticity excellent in usability It relates to a water-based solid cosmetic material.

Water-based solid cosmetics are cosmetics obtained by solidifying the water of the outer phase with water-soluble gelling agents such as carrageenan, agar, locust bean gum, etc. As a good cosmetic, it has been commercialized as a foundation, eye color, blusher, etc.
Conventionally, water-based cosmetics have been studied to give added value such as stability, usability, or moisture retention by specifying gelling agents or combining them with other ingredients while taking advantage of the fresh feeling of use. I came.
For example, a technique for studying usability and stability by specifying a water-soluble gelling agent and a water-soluble thickening agent (for example, Patent Document 1), a pectin that is a water-soluble gelling agent is gelled There are technologies (for example, Patent Documents 2 and 3) that are used in cosmetics and have improved usability and stability over time. Further, there is a technique (for example, Patent Document 4) that improves the filling moldability of a solid cosmetic by using agar and specific powder.
In addition, quality items such as the texture of the finished film and usability such as spread and spread are important quality characteristics particularly in makeup cosmetics such as foundations and eye colors. In oily cosmetics and powder cosmetics, a plate shape The texture and usability of the finished product were changed by blending powder and spherical powder or by limiting the oil agent.

However, conventional water-based solid cosmetics have a gel structure that easily breaks down on the skin as compared with oily cosmetics and powder cosmetics. Therefore, plate-like pearls and glitters, spherical silica, PMMA, polystyrene, nylon When polyurethane, silicone powder, etc. are blended, the feeling of use of the spread spread is improved, but the feeling of rough foreign material is felt and the feeling of use is lowered, and the cosmetic film may become non-uniform. Moreover, since the surface of a water-based solid cosmetic material can be touched many times during use, the surface of the water-based solid cosmetic may become rough or slippery, and the usability may deteriorate.
For this reason, water-based solid cosmetics that maintain high radiance, spread without feeling of foreign matter, have excellent uniformity of the cosmetic film, and are excellent in usability without impairing the freshness inherent in water-based solid cosmetics. Development was desired.

In view of such circumstances, the present inventors have intensively studied. As a result, the water-based solid cosmetic prepared by blending spherical particles having disintegrating properties, pectin and water has a spherical shape with an aqueous system solidified with pectin at the time of application as a carrier. It spreads with the disintegrating particles, and the gel structure of the carrier does not break immediately, and when the cosmetic spreads uniformly, the gel structure and the spherical disintegrating particles disintegrate synchronously, so that a rough foreign body sensation is felt. It has been found that good stretch spread can be obtained without feeling. It was found that after application, it disintegrates and becomes plate-like boron nitride, and the cosmetic quickly adheres to the skin to form a uniform decorative film, resulting in high brightness. In addition, when the cosmetic is taken with a small tool such as a finger or a mat at the time of use, it is found that the spherical disintegrating particles are blended, so that appropriate friction is generated on the cosmetic surface and it is easy to take it. completed.
That is, the present invention includes the following components (a) to (c):
(A) Disintegrating spherical particles comprising as essential components plate-like boron nitride having an average plate diameter of 1 to 20 μm and inorganic powder having an average particle size of 0.01 to 0.5 μm (b) Pectin (c) Water It is intended to provide a water-based solid cosmetic characterized by containing.

  The water-based solid cosmetic of the present invention is a cosmetic having a fresh feel and high brilliancy, spreads without a feeling of foreign matter, has excellent uniformity of the cosmetic film, and has excellent elasticity.

The collapsible spherical particles of component (a) used in the present invention are spherical particles composed of plate-like boron nitride having an average plate diameter of 1 to 20 μm and inorganic powder having an average particle size of 0.01 to 0.5 μm as essential components. Here, “average plate diameter” refers to the average value of the long and short sides of plate-like boron nitride. Specific examples include those described in JP-A No. 2003-104840.
The disintegrating spherical particles of the component (a) have the property of being disintegrated by pressurization as described above, and the disintegration strength is rubbed with a cosmetic tool such as a finger, mat, or sponge on the human skin. The strength is such that it collapses at a certain pressure.
Specifically, the particle disintegration strength of the disintegrating spherical particles of component (a) is determined by uniformly spreading a certain number of particles on a slide glass, placing a planar indenter on the particle, and applying a predetermined amount to the indenter. The particle collapse state is observed with a microscope or the like, and the load value obtained when the particle completely disintegrates is obtained. The particle disintegration strength is preferably 1000 to 50000 Pa, and more preferably 1000 to 30000 Pa when it is assumed to be added to the cosmetic. If it is in this range, it will not disintegrate during the production of cosmetics, but it will easily disintegrate and change into plate-like particles by rubbing on the skin, so it will spread without feeling of foreign matter, and a good aqueous system with excellent cosmetic film uniformity A solid cosmetic can be obtained.
In addition, an inorganic powder having an average particle size of 0.01 to 0.5 μm (hereinafter referred to as “inorganic powder”) used for the collapsible spherical particles is used as a binder for bonding the plate-like boron nitrides during sintering.

Since the water-based solid cosmetic composition of the present invention does not give a sense of foreign material around the component (a) during use, it achieves uniformity of the cosmetic film and good usability. As a carrier of a component for which an effect is expected, the gel formed by the component (b) needs to have elasticity (resistance). Then, the comparative test of the elasticity of the water-system solid composition which a component (b) forms and the water-system solid composition which another water-soluble gelling agent forms was done.
(Test method)
A 3% swelling solution of pectin (LM-104AS, manufactured by CP KELCO) and agar (UP-37, manufactured by Ina Food Industry Co., Ltd.) is prepared, filled in a container, and at 25 ° C., RHEO manufactured by Fudo Kogyo Co., Ltd. The load value was measured using METER NRM-2002D · D. As a load measuring method, a load was applied to the same portion three times in succession with an indenter, a change in the load value was measured, and the result is shown in Table 1. The values in Table 1 were compared with the first measured value, the first time was 1.00, and the second and subsequent times were the ratios obtained by dividing the load value by the first value.

  As shown in Table 1, the water-based solid composition formed by the component (b) of the present invention was hardly changed even when a load was continuously applied to the same part, but other water-soluble gelling agents were not used. The value of the aqueous solid composition formed decreased rapidly when a load was continuously applied to the same location. That is, it was found that the aqueous solid composition formed by the component (b) did not easily disintegrate the gel, and an aqueous solid composition exhibiting resistance was obtained.

  Examples of the water-based solid cosmetic of the present invention include foundations, foundation cosmetics, controls, eye colors, blushers and the like. Among these, the control and eye color are preferable because the effects are conspicuous in terms of a fresh feeling, an excellent spread without feeling of foreign matter, high glitter, and uniformity of the decorative film.
