Description

  The present invention relates to a cosmetic.

  In the cosmetics field, there is an increasing demand for cosmetics that do not feel bulky and that can give a smooth feeling. Conventionally, in water-based cosmetics, a powder is blended for the purpose of imparting a dry feeling when the cosmetic is applied to the skin, and a silicone resin powder is preferably used as the powder.

For example, a gel makeup containing a powder such as a silicone resin powder having an average particle size of 0.1 μm to 100 μm, at least one selected from an antiperspirant active ingredient and a bactericidal agent, and a water-soluble polymer such as a carboxyvinyl polymer A fee has been proposed (see Patent Document 1).
According to this gel cosmetic, even when it is applied to a sticky skin or the like, the slowness of thirst that contributes to stickiness can be improved and a smooth feeling of use can be given.

  In addition, it contains spherical silicone rubber powder and polymethylsilsesquioxane powder, etc., as cosmetics that have both a smooth and smooth feel when applied to the skin and a good feel without stickiness. A skin cosmetic is also proposed (see Patent Document 2).

  However, in these proposed cosmetics, by applying silicone resin powder to water-based cosmetics, the silicone resin powder tends to agglomerate when precipitated, resulting in poor redispersibility and poor usability. There's a problem. Moreover, when this is used by being filled in a spray container or the like, there is a problem that clogging occurs during spraying and the usability is poor.

Therefore, as cosmetics with improved powder redispersibility, spherical powders such as silicone rubber powder, polyoxyethylene alkyl ether phosphoric acid, and 50% by mass or more of alcohol with respect to the total amount of cosmetics are contained. Cosmetics have been proposed (see Patent Document 3).
Moreover, an antiperspirant composition containing an antiperspirant powder component and a nonionic surfactant has been proposed as an antiperspirant powder component that prevents aggregation of the powder (see Patent Document 4).

  However, the redispersibility of these proposed cosmetics and antiperspirant compositions is not sufficient, and there is a problem that clogging occurs when used in a spray container.

  Accordingly, the present situation is that there is a strong demand for cosmetics that are excellent in smoothness and redispersibility without feeling bulky.

Next, each cosmetic after the initial discharge amount measurement was left at 40 ° C. for 1 month. Using this as a measurement sample, shake every 5 days under the same conditions as in the evaluation of redispersibility, then repeat 3 push sprays, and measure the total discharge amount (mass) of 3 pushes with an electronic balance. (Hereinafter referred to as “test discharge amount”).
When the “relative discharge amount” represented by the following formula 1 was 50 or less, it was determined that clogging occurred, and the number of days from the start of the test until clogging was calculated. Ten tests were carried out for each cosmetic, and the average value (average days) was calculated and evaluated based on the following evaluation criteria.
Relative discharge amount = test discharge amount / initial discharge amount × 100 [Equation 1]
