Description

  The present invention relates to a non-aqueous warm skin cleansing composition.

  Conventionally, means for imparting a thermal effect by mixing with water and improving the cleansing effect has been used. As those that impart such a thermal effect, the heat of hydration of alcohols and polyhydric alcohols is mainly used from the viewpoint of safety to the skin and mildness of heat generation.

  Specifically, non-aqueous cosmetics containing alcohol and sorbite ether (see, for example, Patent Document 1), gel-type thermal massage materials containing glycerin or diglycerin, an anionic polymer compound, and water (eg, patents) Means such as massage cosmetics (see, for example, Patent Document 3) containing a specific polyhydric alcohol, a scrub agent, and a water-soluble polymer compound have been proposed.

  However, when the heat of hydration of alcohols and polyhydric alcohols is used, there is a mild expression of warmth, and the heat generation time is short because it is easily mixed with water, making it difficult to obtain the desired warmth. There is. Moreover, in order to obtain an appropriate thermal feeling, it must be blended in a large amount, and there is a problem that it is inferior in use feeling such as a sticky feeling.

  In addition, as compared with alcohols and polyhydric alcohols, an attempt has been made to use an inorganic salt that instantly exhibits a thermal effect when mixed with water. Specifically, cleansing pack cosmetics containing magnesium sulfate (see, for example, Patent Document 4), skin cosmetics containing exothermic agents and warming agents (see, for example, Patent Document 5), specific oils, and Means such as a non-aqueous cosmetic containing an inorganic salt and an activator (see, for example, Patent Document 6) have been proposed.

  However, when the heat of hydration of these inorganic salts is used, an excellent thermal effect can be obtained, but in nature, the dosage form must be non-aqueous, so-called oil-based dosage form, There is a problem that it is inferior to the feeling of use such as poor washing.

  On the other hand, an effect required for a skin cleansing cosmetic is to have a refreshing refreshing feeling. Usually, in order to give such a feeling of use, a refreshing agent is mix | blended. However, there is a problem that even when a refreshing agent is added to the cosmetics having a thermal feeling due to the alcohols and polyhydric alcohols described above, the refreshing feeling exceeds the thermal feeling and a sufficient thermal feeling cannot be obtained. Moreover, even if it mix | blends with the cosmetics which have the thermal feeling by an inorganic salt, there exists a problem that it is inferior to the actual feeling of the refreshing refreshing feeling after rinsing badly.
