Description

  The present invention relates to a water-in-oil cosmetic. In the present invention, a composition for cosmetics may be described as cosmetics.

  When applied to the skin, the polyhydric alcohol generates heat of hydration by reaction with a small amount of moisture on the skin, so that when used in a cosmetic, a warming effect can be imparted.

  There are various types of warm cosmetics. For example, a technique is known in which a fluid polyhydric alcohol is blended into a foam dosage form in order to carry it (Patent Document 1: Japanese Patent Application Laid-Open No. 2005-350378). However, the foam dosage form is expensive due to the use of special containers.

  On the other hand, in order to reduce costs and prevent the storage stability of cosmetics and sagging during application, a technology is known that can add viscosity by adding a water-soluble polymer compound or fine particle powder to a polyhydric alcohol as a continuous phase. (Patent Document 2: JP 2013-35783 A, Patent Document 3: JP 2011-225522 A). However, the spread of cosmetics on the skin due to the water-soluble polymer compound, and itching of fine particle powder can be felt.

  From the results of Table 2 above, it can be seen that the water-in-oil cosmetic of Example 1 is excellent in feeling of use (no itchiness), warmth (warmth effect during application), and elongation (extensibility). It was. Comparative Example 1 and Comparative Example 2 in which the continuous phase is thickened with a water-soluble polymer or fine particle powder are not preferable because the elongation is poor and itching is felt.

  From the results in Table 3 above, the water-in-oil cosmetics of Examples 2 to 9 have a feeling of use (no itchiness), a feeling of warmth (warming effect at the time of application), elongation (extensibility), and viscosity (makeup). It was found that the material was excellent in the sag of the material) and in the emulsified state (state at the time of aqueous phase transfer). In Comparative Example 3 in which the mass ratio of the component (b) to the total content of the component (b) and the component (c) of the present invention is 95% or less, no warm feeling is obtained, and the component (a) is simply replaced with another silicone. Comparative Example 4 replaced with an active agent, Comparative Example 5 replaced with a silicone elastomer, Comparative Example 6, Comparative Example 7 or Comparative Example 8 in which the aqueous phase in the entire cosmetic composition is not 57 to 90% is poorly emulsified. It is not preferable because of its low viscosity.
