  Hereinafter, the present invention will be described in detail.

  The warm-sensitive transparent foaming detergent composition of the present invention contains a polyhydric alcohol and one or more nonionic surfactants having a polyglycerin skeleton as essential components.

<Polyhydric alcohol>
As the polyhydric alcohol, generally known polyhydric alcohols can be used. Specifically, propylene glycol, 1,3-butylene glycol, dipropylene glycol, polyethylene glycol, glycerin, diglycerin, Sorbitol, isoprene glycol, 1,2-pentanediol, 1,2-hexanediol, 1,2-octanediol, 2,4-hexylene glycol and the like can be used. In addition, these polyhydric alcohols may be used alone or in combination of two or more.

  These polyhydric alcohols bring warmth to the skin by heat of hydration with skin moisture when using the warm-sensitive clear foaming detergent composition of the present invention. For this reason, in the present invention, the content of the polyhydric alcohol may be an amount that can bring a warm feeling to the skin by heat of hydration with the moisture of the skin. On the other hand, it is preferably 60% by weight or more, particularly preferably 75% by weight or more. When the content of the polyhydric alcohol is less than 60% by weight based on the whole composition, there is a possibility that sufficient warmth cannot be provided to the skin.

<Nonionic surfactant>
The nonionic surfactant used in the present invention has a structure having a polyglycerin skeleton, that is, has a foaming property when blended with other components, transparently dissolved in a polyhydric alcohol without moisture. If there is, it will not be specifically limited. Whether or not the nonionic surfactant is transparently dissolved in the polyhydric alcohol without moisture is determined by visual observation, as well as a solution obtained by dissolving the nonionic surfactant in the polyhydric alcohol without moisture at room temperature. The L value when measured using a color difference meter SE2000 manufactured by Nippon Denshoku is 90 or more, more preferably 95 or more.

  In the present invention, specific examples of the nonionic surfactant having a polyglycerin skeleton include polyglycerin fatty acid ester and polyglycerin alkyl ether. Polyglycerin fatty acid ester and polyglycerin alkyl ether have foamability and are transparently dissolved in polyhydric alcohol without moisture.

  Specific examples of the polyglycerin fatty acid ester are preferably esters of saturated, unsaturated or branched alkyl groups having 8 to 22 carbon atoms and polyglycerin having a polymerization number of 2 to 12. Is decaglycerin monocapric acid ester, decaglycerin monolauric acid ester, decaglycerin monomyristic acid ester, decaglycerin monopalmitic acid ester, decaglycerin monooleic acid ester, decaglycerin dilauric acid ester, decaglycerin dimyristic acid ester , Pentaglycerin monocapric acid ester, pentaglycerin monolauric acid ester, pentaglycerin monomyristic acid ester, pentaglycerin monopalmitic acid ester, pentaglycerin monooleic acid ester, etc. It is possible.

  Moreover, as a specific example of a polyglycerol alkyl ether, a saturated, unsaturated or branched alkyl group having 8 to 22 carbon atoms is preferably ether-bonded to a polyglycerol having 2 to 12 polymerizations. Tetraglycerin decyl ether, tetraglycerin lauryl ether, tetraglycerin myristyl ether, tetraglycerin palmityl ether, tetraglycerin oleyl ether, hexaglycerin decyl ether, hexaglycerin lauryl ether, hexaglycerin myristyl ether, hexaglycerin palmityl ether, hexa Glycerin oleyl ether or the like can be used. In addition, such polyglycerin alkyl ethers are suitable for blending into a facial warm-sensitive transparent foaming detergent composition because they are less likely to stain the eyes compared to the above-described polyglycerin fatty acid esters.

  The nonionic surfactants described above may be used alone or in combination of two or more.

  In the present invention, the total content of the one or more nonionic surfactants described above is an amount that can be dissolved in the polyhydric alcohol and that the composition can provide cleansing properties to the skin. What is necessary is just to be 1 to 40 weight% with respect to the whole composition, and it is more preferable that it is 3.0 to 20.0 weight%. When the content of the nonionic surfactant is less than 1% by weight relative to the whole composition, there is a possibility that sufficient detergency cannot be obtained, and when it is more than 40% by weight There is a risk that the cleaning power is too strong or a feeling of irritation is felt.

<Thickener>
Moreover, the thickening agent may be mix | blended with the warm sensitive transparent foaming detergent composition which concerns on this invention in order to provide a composition with thickening. Examples of the thickener include a carboxyvinyl polymer and a copolymer represented by the above general formula (1) (acrylates / stearate itaconate). In particular, an (acrylates / stearic acid itaconate) copolymer is excellent in viscosity and easily soluble in the polyhydric alcohol, so that it can be suitably used in the present invention.

  It is preferable that the content of the carboxyvinyl polymer blended when imparting thickening to the composition is 0.01 to 2.0% by weight with respect to the entire composition. When the content of the carboxyl polymer is less than 0.01% by weight relative to the entire composition, there is a possibility that sufficient thickening cannot be obtained, and when it is more than 2.0% by weight, Viscosity is too high, and there is a risk of spreading during use.

  It is preferable that the content of the (acrylates / stearate itaconate stearate) copolymer blended when imparting thickening to the composition is 0.1 to 5.0% by weight with respect to the entire composition. If the content of the (acrylates / stearate itaconate) copolymer is less than 0.1% by weight relative to the total composition, there is a possibility that sufficient thickening cannot be obtained, and 5.0% by weight. When the amount is larger, the viscosity is too high and the spread during use may be deteriorated.

  As a neutralizing agent for carboxyvinyl polymer and (acrylates / stearate itaconate) copolymer, a basic substance usually used for thickening can be used without any problem.

  For example, sodium hydroxide, potassium hydroxide, triethanolamine, monoethanolamine, aminomethylpropanol, etc. can be mentioned. Further, a very small amount of water may be used for dissolving an inorganic electrolyte such as sodium hydroxide or potassium hydroxide.

<Silicone surfactant>
Moreover, the silicone type surfactant may be mix | blended with the warm sensitive transparent foaming detergent composition which concerns on this invention. According to the blending of the silicone surfactant, the effect of dropping the oily makeup cosmetics is imparted to the composition.

  As the silicone-based surfactant, it is sufficient that the polysiloxane is a skeleton and a polyoxyalkylene group such as polyoxyethylene or polyoxypropylene is added. Specific examples include a polyoxyethylene / methylpolysiloxane copolymer, Poly (oxyethylene oxypropylene) methyl polysiloxane copolymer, polyoxyethylene alkyl polysiloxane polyoxypropylene alkyl polysiloxane dimethyl polysiloxane copolymer, methyl polysiloxane alkylmethyl polysiloxane poly (oxyethylene oxypropylene) methyl Examples include polysiloxane copolymers.

  It is preferable that the content of the silicone-based surfactant to be blended for imparting the makeup removing effect is 0.1 to 5.0% by weight with respect to the entire composition. When the content of the silicone surfactant is less than 0.1% by weight relative to the whole composition, there is a possibility that a sufficient makeup removing effect may not be obtained, and when the content is more than 5.0% by weight In some cases, dissolution in the system becomes insufficient, and it becomes opaque and non-uniform.

<Oil content>
Further, the warm-sensitive transparent foaming detergent composition according to the present invention may be provided with a makeup removing effect by blending oil.

  Any known oil can be used, for example, liquid paraffin, isoparaffin, methylpolysiloxane, methylphenylpolysiloxane, decamethylcyclopentasiloxane, various vegetable oils, squalane, dipentaglycol neopentyl glycol, 2 -Glyceryl ethylhexanoate, cetyl 2-ethylhexanoate, octyl palmitate, isocetyl isostearate, myristyl myristate, diethoxyethyl succinate, diethylene glycol diethyl ether and the like can be used.

  It is preferable that the content of the oil blended when imparting the makeup removing effect is 0.01 to 5.0% by weight with respect to the entire composition. If the oil content is less than 0.01% by weight with respect to the entire composition, there is a risk that a sufficient makeup-removing effect may not be obtained. It may not be solubilized by the activator and may become opaque and non-uniform.

<Moisture content>
In order to obtain a strong warm feeling, the water content in the warm-sensitive transparent foaming detergent composition according to the present invention is 10% by weight or less. More preferably, it is 5% by weight or less.

  If the water content is more than 10% by weight, the polyhydric alcohol and water react in the composition during the production to generate heat of hydration, so that the heat of hydration generated during use is small and sufficient for the skin. A warm feeling cannot be obtained. In other words, the smaller the amount of water, the more heat of hydration is generated during use and the skin has a sufficient warmth, so the amount of moisture in the warm sensitive transparent foaming detergent composition according to the present invention. Is preferably as low as possible, and is particularly preferably 0% by weight.

<Other ingredients>
In the warm sensitive transparent foaming detergent composition according to the present invention, as long as the effects of the present invention are not impaired, components that are usually blended in the detergent composition, for example, EDTA salt or hexametaphosphoric acid, as necessary. Various agents such as salt sequestering agents such as salts, bactericides, preservatives, anti-inflammatory agents, granules, capsules, pigments, fragrances and the like may be blended.

  The warm-sensitive transparent foaming detergent composition according to the present invention as described above can be filled and stored in various containers such as bottle type, pump type, and tube type. Moreover, since the warm sensitive transparent foaming detergent composition which concerns on this invention has warm sensitivity and foaming property, by applying to a skin and massaging, obtaining the blood circulation promotion effect by warm sense effect | action It is possible to wash dirt and sebum on the skin, and after finishing the massage, it is possible to obtain a refreshing feeling by adding water and bubbling away. Moreover, since the warm sensitive transparent foaming detergent composition which concerns on this invention is transparent and uniform, there exists a clean feeling, it is easy to handle, and its market value is high.
