Description

  The present invention relates to a powdery cosmetic material containing a water-hydrophobized composition (hereinafter referred to as a water-containing composition), and more specifically, reduces the squeaky feeling and stickiness during application specific to water-containing powder cosmetics. In addition, the present invention relates to a water-containing powder cosmetic that can form a cosmetic film that has a fresh feel and good spread, improves adhesion to the skin, smoothes the skin, and provides a transparent feeling.

Conventionally, a technology of a water-containing powder cosmetic has been developed that, when used in powder form, is liquefied when used and produces liquid-type characteristics (see, for example, Reference 1), and such cosmetics are on the market. However, there were times when the feeling of use was squeaky or sticky. This is because water-containing powder cosmetics often have a structure in which an aqueous component is coated with silica, and after water is released during use, the squeaky feeling of silica in the cosmetic film is strongly felt. This is thought to be the cause.
In addition, water-containing powder cosmetics are often used to increase the storage stability of a drug such as vitamin C that is water-soluble and poorly stable in aqueous solutions in cosmetics. There was room for improvement in adhesion and makeup effects.
Therefore, when a specific amount of a specific hydrophobized silicic acid anhydride, a specific amount of a powder component, a specific amount of an aqueous component, and a pearl agent / lamé agent are further blended, the texture that they have (pearly feeling / glitter feeling) It contains a technology that can exhibit high transparency without impairing color sense, hue, etc. (see, for example, Patent Document 2), water-containing powder, and silicone-based powder having surface activity. Technology has been developed that sometimes feels cold quickly, has no powderiness or squeaky feeling, has a fresh feeling of use, and has excellent uniformity and makeup durability of the finished cosmetic film and excellent storage stability (for example, And Patent Document 3).

JP-A-5-65212 JP 2003-267826 A JP2004-300057

However, it is difficult to eliminate the squeaky feeling, and the powder is wetted by the water released by rubbing, resulting in stickiness and spread spread. In addition, it is difficult to improve the adhesion of the cosmetic film without deteriorating the feeling of use, and it has not been studied to obtain a transparent feeling by adjusting the texture of the skin.
Therefore, a cosmetic film that reduces the squeaky and sticky feeling when applying hydrous powder cosmetics, has a fresh feel and good spread, improves the adhesion to the skin, improves the texture of the skin, and provides a transparent feeling The development of cosmetics that can be formed has been desired.

(Production method)
A. Ingredients 1 to 4 were heated and dissolved at 85 ° C., cooled and solidified, and then ground at −80 ° C. to obtain aqueous gel particles (about 10 to 100 μm).
B. At room temperature, component 5 was added to A and mixed with a Henschel mixer (manufactured by Mitsui Miike) to prepare a water-containing composition.

(result)
As is apparent from Table 1, the water-containing powdered white powders of Examples 1 to 7 have an excellent feeling of use that gives freshness, spreads with little squeaky feeling, and provides a decorative film with a fine and transparent feeling. It was.

On the other hand, in Comparative Example 1 using a fluorinated talc instead of the component (D), the elongation spread was poor and the squeakiness was conspicuous, and a satisfactory one was not obtained. This is thought to be because the feel of the fluorinated, extremely hydrophobic oleophobic oil deteriorated.
In Comparative Example 2 using untreated talc instead of component (D), a part of the water-containing powder collapsed, it was difficult to feel freshness, and the skin became sticky. This is probably because the untreated talc is hydrophilic, so that the water-containing powder stabilizer (component (A)) is less likely to carry moisture, and part of the moisture is released, resulting in a dry crisp feel.
In Comparative Example 3 containing no component (E), the elongation was poor, the film was white, and a satisfactory product was not obtained. This is considered to be because the uniformity of the decorative film was lost and the transparency was not obtained because the powder was not contained by rolling the skin like the component (E).
In Comparative Example 4 using a cross-linked polystyrene instead of the component (E), a satisfactory product was not obtained because of poor elongation on the skin.
