Description

Although the present invention is a powder cosmetic, it liquefies and is fresh when rubbed at the time of use, changes in temperature sensation (cold or warm), does not feel powdery or creaky, and spreads smoothly and evenly when applied. The present invention relates to a powdery cosmetic which has excellent emollient feeling, anti-secondary adhesion effect, and excellent stability over time to maintain the powdery state while having the properties, color developability and glossy feeling.

Conventionally, as powdered cosmetics, white powder, whitening powder, foundation, eye shadow, cheek color, etc. are known. There were problems such as dryness and dry skin. In addition, in emulsified cosmetics, although moisturizing properties can be imparted, there has been a tendency for the long-lasting effect of makeup to be insufficient. Therefore, attempts have been made to add elements such as water, oil, and liquid emulsified cosmetics to powder cosmetics for the purpose of promoting the penetration of drugs into the skin and imparting moisture, oil content, moisturizing properties, and emollient properties.
For example, as disclosed in Patent Documents 1 to 3, a specific amount of powder treated with a compound having a specific hydrophobized silicic anhydride and a specific perfluoropolyether group, water and an oily component are combined and rubbed together. Powder cosmetics that liquefy have been developed.
Further, as exemplified in Patent Document 4, a makeup protective agent containing trifluoropropylcyclopolysiloxane, fluorine compound-treated silica, and a partially crosslinked fluorine-modified organopolysiloxane polymer and having a secondary adhesion-less effect is provided. being developed.

However, for example, the powder cosmetics described in Patent Documents 1 to 3 have relatively high makeup durability such as emollient feeling and strong water and oil repellency against sweat and sebum, but all of them are coated with fluorine compounds. Powder is used, and because it is a powder, it is localized on the skin, so it partially exhibits strong water and oil repellency, lacking continuity of the makeup film, and depending on the part used, the makeup may not last long. In particular, the secondary adhesion resistance effect, the effect of improving the color developability and the glossiness were not always at a satisfactory level.
In addition, for example, the protective material with a secondary adhesion-less effect described in Patent Document 4 is an oil-based formulation that spreads freshly and newly imparts a change in temperature sensation (cold or warm) and moisture. There was no effect, and it was difficult to achieve compatibility with the secondary adhesion-less effect. In addition, when a thick coating is applied on top of the cosmetics, some cosmetics may hinder internal color development and glossiness.

Therefore, even though it is a powder cosmetic, when it is applied, it liquefies and becomes fresh when rubbed, and the temperature sensation changes (cold or warm). It has a highly emollient feel while having high elasticity, color development, and a glossy feel. There has been a demand for a powdery cosmetic that is long-lasting, has a good secondary adhesion-free effect, and is excellent in stability over time to maintain the powdery state.

Under such circumstances, the present inventors have made intensive studies and found that when a cosmetic containing a fluorine oil is powdered with a specific hydrophobized silicic anhydride, a coloring agent, and an aqueous component, it is possible to use it even though it is a powder cosmetic. When applied, it liquefies and becomes fresh, and you can feel a change in temperature sensation (cold or warm) without feeling powdery or creaky. At the same time, it has a highly emollient feel and maintains powder adhesion over time and strong water and oil repellency against sweat and sebum. The present invention was completed based on the discovery that powdery cosmetics with excellent stability can be obtained. Furthermore, by blending a fluorine oil thickener in addition to the above ingredients, it becomes easier to hold the fluorine oil in and stabilize the dispersion, and the fluorine oil content can be increased. It was found that the water and oil repellency against sebum is further enhanced, and the secondary adhesion resistance effect is further improved.

That is, the present invention includes the following.
[1] the following components (A) to (D);
(A) Hydrophobized silicic anhydride having a specific surface area of 25 m ² /g or more (B) As the aqueous component, one or more selected from (b-1) water and (b-2) polyhydric alcohols (C) Coloring agent (D) A powder cosmetic that contains a fluorine oil and is liquefied by rubbing.
[2] A powder cosmetic that further contains component (E) a fluorine oil thickener.
[3] A powder cosmetic containing (b-3) a water-soluble polymer in addition to the component (B).
[4] A powder cosmetic containing 0.5 to 35.0% by mass of component (D) and component (E) in total.
[5] A powder cosmetic containing a sugar alcohol as the component (b-2).
[6] A powder cosmetic that changes color when rubbed.
[7] To provide a powder cosmetic used as a make-up cosmetic.

Although the present invention is a powder cosmetic, it liquefies when rubbed at the time of use, feels fresh, feels a change in temperature sensation (cold or warm), does not feel powdery or creaky, and spreads smoothly when applied.

An oil layer containing component (D) and component (E) is dispersed on the outside of component (A) or on the surface of (A), and a powder layer containing component (C) is present between or inside each layer. Conceivable. The powder layer containing the component (C) preferably has a hydrophobic surface when dispersing in the air layer, and preferably has a hydrophilic surface when dispersing in the inner water layer. When force is applied by rubbing, this structure is destroyed, and the powdered component (B) undergoes a phase change from the inside to the outer layer and liquefies, giving a fresh spread and a change in temperature sensation (cold or warm). , The powder layer is dispersed in either the water layer or the oil layer to form a uniform cosmetic film. It is considered to be effective. However, the structure is not limited to this.

Regarding the position of the component (C) in the present invention, the component (C) is simultaneously blended in two of the three layers of the water layer, the oil layer, and the air layer, and the component (C) is blended in each layer. A gap between the appearance color and the as-applied color can sometimes be created when the overall hue of the coating is different. It is desirable to consider the content position according to the polarity of the surface of component (C). When blended in the oil layer containing D), the stability over time is improved. For example, an oil-soluble colorant such as Red No. 218 or Red No. 223, which is the component (C), is added to the oil layer, and a water-soluble colorant such as Red No. 227 is added to the component (B). or simultaneously use the component (C) on the hydrophilic surface in the water layer and the component (C) on the hydrophobic surface in the air layer, or pre-disperse the component (C) on the hydrophobic surface in the oil layer By simultaneously using component (C) for the hydrophobic surface in the air layer, it is possible to create a gap between the appearance color and the color at the time of application. However, it is not limited to this method.

Although the production method of the present invention is not particularly limited, for example, component (D) and component (E) are uniformly mixed with powder cosmetic obtained by mixing and dispersing component (A) and component (B). A powdery cosmetic having the structure described above is obtained in the above operation. The manufacturing equipment is not particularly limited, and the component (B) and the oil layer may be freeze-pulverized or stirred and dispersed in advance to prepare particles according to hardness, and stabilized in a powder layer.

On the other hand, Comparative Example 1, in which neither component (D) nor oil was blended, was insufficient in terms of emollient feeling and secondary adhesion-free effect. Comparative Example 2, in which the component (D) was not blended and a material soluble in water and oil was blended, was poor in all evaluations because it was difficult to maintain the powder state (stability over time). Comparative Examples 3 and 4, in which the component (D) was not blended and replaced with another oil agent, had a low secondary adhesion resistance effect, a change in properties from a powder state to a liquefied state (freshness), and a change in temperature sensation (coolness). The texture) and the uniformity of the coating film tended to decrease a little. Comparative Example 5, in which the component (A) was not blended, was poor in property change (freshness) from the powder state to the liquefied state. Comparative Example 6, in which component (B) is not blended, has a secondary adhesion-less effect, but it is difficult to maintain stability as a powder cosmetic. Due to the lack of adhesion of the powder and lack of uniformity due to the lack of content, the color development and glossiness were reduced.

(Production method)
A. Mix and dissolve (1) to (5), add (6) and (7), cool, and freeze-pulverize to powder.
B. (8) and (9) were mixed and dispersed with A, and slowly mixed and stirred with the mixture of (10) to (12) to prepare powder cosmetics.

The obtained sunscreen powder cosmetic has a property change (freshness) from a powder state to a liquefied state, a high change in temperature sensation (coolness), uniformity of the coating film, emollient feeling, and no secondary adhesion. It was highly effective, maintained in a powder state (stability over time), had color developability, and was maintained over time.
