Description

  The present invention relates to a warming detergent. More specifically, the present invention relates to a warming detergent capable of giving a warm feeling when washed away and effectively removing a square plug while having a massage effect at the time of use.

  Conventionally, as one of attempts to remove sebum dirt clogged in pores, means for improving the cleansing effect by adding a thermal effect by mixing with water 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.

  For example, non-aqueous cosmetics containing alcohol and sorbite ether (see Patent Document 1), glycerin or diglycerin, anionic polymer, pepper tincture or ginger tincture, and gel-like thermal massage material containing water (Patent Document) 2), a humectant such as glycerin, 1,3-butylene glycol, dipropylene glycol or polyethylene glycol, a scrub agent such as spherical polyethylene, spherical polyester, spherical nylon or microcrystalline cellulose, and a water-soluble polymer compound. The massage cosmetics (refer patent document 3) to mix | blend are mentioned.

  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, there is also a problem that the adhesion to the skin during application is inferior.

  On the other hand, as compared with alcohols and polyhydric alcohols, attempts have been made to use inorganic salts that instantly exert a thermal effect when mixed with water. For example, a cleansing pack cosmetic containing anhydrous magnesium sulfate, monohydrate or tetrahydrate (see Patent Document 4), calcium chloride, magnesium chloride, aluminum chloride, ferric chloride, zinc chloride , Magnesium sulfate, zinc sulfate, ferrous sulfate, aluminum sulfate, calcium sulfate, dried alum, calcium oxide, sodium carbonate, sodium hydrogen phosphate, activated zeolite, potassium carbonate, and other exothermic agents, pepper powder, pepper tincture, etc. Skin cosmetics containing a warming agent (see Patent Document 5), specific oils, inorganic salts or inorganic oxides such as magnesium chloride, calcium chloride, magnesium sulfate, and nonionic surfactants and / or cations Non-aqueous cosmetics containing a surfactant (see Patent Document 6) have been reported.

JP-A-6-80534 Japanese Patent Laid-Open No. 11-12126 JP 2000-247860 A Japanese Patent Laid-Open No. 7-173033 Japanese Patent Laid-Open No. 11-60460 JP-A-11-228332

  However, when an inorganic salt is added to the cleaning agent in consideration of the prior art, the cleaning effect is improved due to the excellent thermal effect, but because of the nature, the dosage form must be a non-aqueous type, so-called oily type, so that it is sticky. There is a problem that the feeling of use such as feeling is inferior. In addition, there is a problem that the oil component is separated, resulting in poor adhesion to the skin during application.

  An object of the present invention is to provide a warming cleaning agent that is excellent in both cleaning effects such as a square plug removal effect and a feeling of use such as a feeling of close contact with the skin at the time of application and a skin feel after cleaning. .

  As a result of repeated studies to solve the above-mentioned problems, the present inventors incorporated octenyl succinic acid corn starch ester aluminum into an oil gelling agent, an inorganic acid salt anhydride, and a warming detergent containing a surfactant. As a result, it was found that it was excellent both in the cleaning effect such as the effect of removing horn plugs, and in the feeling of use such as the feeling of adhesion to the skin at the time of application and the skin feel after the cleaning, and the present invention was completed. .

That is, the present invention, (A) octenyl succinate of corn starch esters aluminum, (B) oil gelling agents, Ri Na contain (C) an anhydride of an inorganic salt, and (D) a surfactant, wherein (B ) A warming detergent whose component is dextrin fatty acid ester and / or 12-hydroxystearic acid .

  The warming sensation agent of the present invention has an excellent effect that the exothermic effect lasts and is excellent in removing horn plugs, and also excellent in the feeling of adhesion to the skin during application and the skin feel after washing. .

  In addition to (B) oil gelling agent, (C) inorganic acid salt anhydride, and (D) surfactant, (A) octenyl succinic acid corn starch ester aluminum is added to the warm cleaning agent of the present invention. Has major features. The warming detergent of the present invention is a non-aqueous composition containing the above components, and it is desirable that water is not substantially contained. Here, “substantially contain no water” means “not to add water separately”, and does not exclude a trace amount of water contained in each raw material.

  An inorganic acid salt anhydride (hereinafter sometimes referred to as an inorganic acid salt anhydride) has a property of generating heat due to hydration reaction due to water absorption and moisture absorption. Therefore, it is important to prevent contact between the inorganic acid anhydride and moisture until use, and the warming detergent is blended into an oily type (also referred to as non-aqueous type). However, when an oil gelling agent or surfactant generally used for an oil-based warming detergent is combined with an inorganic acid salt anhydride, there is a sticky feeling and the usability is not sufficient. Thus, as a result of the study by the present inventors, surprisingly, when octenyl succinate corn starch ester aluminum, which is a lipophilic powder, is further blended, the formulation stability is improved and the exothermic effect of inorganic acid anhydride is improved. It has been found that not only the cleaning effect is improved continuously, but also an excellent feeling of adhesion to the skin at the time of application and an excellent skin feel after cleaning are obtained.

  EXAMPLES Hereinafter, although this invention is demonstrated based on an Example and a comparative example, this invention is not limited at all by these Examples.

Examples 1-12 and Comparative Examples 1-14
The warming detergents having the compositions shown in Tables 1 to 4 were prepared by warming (B) and (D) components and oily components, and then adding the powders and stirring with a disper. did.

  Next, the obtained warming cleansing agent is used as a facial cleansing agent, and the heat generation (warmth) effect at the time of washing, the persistence of heat generation, the effect of removing the plugs, the feeling of adhesion at the time of application (to the skin of the cleaning agent) Adhesiveness), good wash-off, and smoothness of the skin after washing were judged (sensory evaluation) by 20 professional panelists and evaluated according to the following evaluation criteria. The results are shown in Tables 1 to 4.

〔Evaluation criteria〕
A: Very good (more than 16 out of 20 answered good)
○: Good (11-15 out of 20 responded good)
Δ: Normal (6-10 out of 20 responded good)
X: Defect (answer that 5 or less out of 20 are good)
