Problems solved by technology

The reason for this is as follows. If the amount of the oily component is increased in the powder cosmetic, there will be a good tendency to produce a moist feeling and improve the comfort on the skin. However, if the amount exceeds the above range, the amount of the oily component will be too much. , Agglomeration occurs between the powders, and it is difficult to call it a powder cosmetic, and there is agglomeration on the surface of the filler (the surface becomes hard and it is difficult to pick up with a puff (sponge)), making it difficult to use.

Embodiment

[0055] Hereinafter, examples are given to describe the present invention in detail, but the present invention is not limited by these examples.

reference example 1

[0057] Preparation of flat cellulose particles (1):

[0058] Refined wood pulp-derived cellulose powder (NIPPON PAPER Chemicals: KC FLOCK W-400 (water content in air-dried state: 7%)) was dried under reduced pressure at 40°C, and the adsorbed moisture was sufficiently removed to make it less than 0.1%. 49 g of this cellulose powder was put into a sealable zirconia grinding container (500 ml in volume) together with grinding balls made of zirconia (diameter: 20 mm), and stearic acid was added to make it 2%.

[0059] Thereafter, the pulverization container was set in a planetary ball mill (Germany Fritsch: P-5 type), and pulverization was performed by continuously repeating 72 cycles of rotation pulverization for 10 minutes to pause for 10 minutes. The rotation speed at this time was set to 200 rpm (grinding energy of about 10G (gravitational acceleration)). The pulverized product is obtained in the form of powder.

[0060] The powder was dispersed in water in a flow cell, a...

[0072] Comparison with solid substances formed by oil agents (1):

[0073] According to the formulation in Table 1, the flat cellulose particles, cellulose powder, hemp cellulose powder (TOSCO Corporation: TOSCO hemp cellulose powder), talc or sericite prepared in Reference Example 1 were uniformly mixed with the oily component (squalane) Mix, press fill in metal molds to make solid mass. The surface state of the solid matter was visually evaluated, and the pick-up property on the sponge was evaluated according to the following evaluation criteria. Their results are listed in Table 1.

Abstract

The invention aims to provide a powder cosmetic in which the powder component causes no aggregation and the surface powder component causes no caking in press processing even if a large amount of oily component is contained therein. Said powder cosmetic is characterized by comprising oblate cellulose particles and an oily component.

Description

[0001] This application is a divisional application, the international application number of the original application is PCT / JP2009 / 065056, the Chinese national application number is 200980134277.0, the filing date is August 28, 2009, and the invention name is "powder cosmetics". technical field [0002] The present invention relates to a powder cosmetic, and more specifically, to a powder cosmetic capable of mixing a larger amount of oily components than conventional powder cosmetics. Background technique [0003] Powder cosmetics containing powder ingredients such as foundation and eye shadow are a large category in the field of cosmetics. [0004] These powder cosmetics are obtained by uniformly mixing and dispersing powder components such as body pigments and pigments and oily components as a binder to obtain a powder mixture, and then filling the metal pan with the mixture, pressing and filling , and perform molding to obtain powder cosmetics. [0005] Among the powder...
