Description

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

  Conventionally, attempts have been made to impart a thermal effect by mixing with water. 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 a non-aqueous type, so-called oil-based dosage form, such as oiliness and stickiness. There is a problem that the feeling of use is inferior.

In addition, the effect of promoting blood circulation by the foaming of carbon dioxide gas is added, and the effect of improving dullness is achieved.

  In addition, when the non-aqueous warm skin composition of the present invention is used as a shaving agent, in addition to the unique effects of the present invention, it is easy to shave by softening the eyelids by the steaming effect of an appropriate warm feeling, The foaming of carbon dioxide gas provides an effect that blade sliding is improved and the effect of reducing the burden on the skin by a razor can be imparted.

  EXAMPLES Hereinafter, although this invention is demonstrated further in detail based on an Example, this invention is not limited only to these Examples. The blending amount represents “% by weight” unless otherwise specified. Moreover, all evaluation was implemented on the constant conditions of constant temperature and humidity of 23 degreeC and 60% of humidity.

(Sample preparation 1)
In accordance with the compositions described in Tables 1 and 2, the nonaqueous warm skin compositions of Examples 1 to 4 and Comparative Examples 1 to 4 and the polyhydric alcohol warm skin composition of Comparative Example 5 were used in a conventional manner. And prepared for the following evaluation. The results are shown in Table 1 and Table 2, respectively.

(Test Example 1: Evaluation 1 of use feeling)
Twenty expert panels apply the samples obtained in each of the examples and comparative examples to dry cheeks, get the fingertips wet, and massage for 1 minute to apply the sample. Sensory evaluation was performed according to the following evaluation criteria for “warm feeling” and “oiliness”. In addition, after rinsing, moisture was wiped off by towel drying.

<Evaluation criteria for thermal feeling>
◎: More than 16 out of 20 responded that there was a moderate warm feeling ○: 11-15 out of 20 responded that there was a moderate thermal feeling △: 6-10 out of 20 persons had a moderate thermal feeling Answer that there is ×: Less than 5 out of 20 people say that there is a moderate warmth
