Abstract
The purpose of the present invention is to provide a water-in-oil type temperature-sensitive cosmetic that exhibits an excellent temperature-sensitive imparting effect, has a good feeling of use, and has excellent storage stability. The invention relates to a temperature-sensitive cosmetic which is characterized by containing polyol, an oil phase thickener, an emulsifier and water.
Description
Technical Field
The present invention relates to a temperature-sensitive cosmetic that imparts a temperature-sensitive feel when applied to the skin. More particularly, the present invention relates to a water-in-oil type temperature-sensitive cosmetic which has excellent emulsion stability, exerts a cosmetic effect, and has a good feeling of use.
Background
Generally, it is known that imparting a moderate temperature sensation to the skin promotes blood circulation of the skin, increases metabolism, and provides a blood color improving effect, a relaxing effect, a fatigue recovery effect, and the like. Therefore, these effects are expected to be expected to allow the blending of a heat-generating substance into a cosmetic. As a heat-generating substance to be blended in cosmetics, a moisturizing agent such as a polyhydric alcohol, zeolite, a metal salt, a metal oxide, or the like has been widely used. These are all hygroscopic and generate heat when they come into contact with moisture on the skin, thereby giving a feeling of warmth to the skin.
Patent document 1 proposes a polyol-in-oil type temperature-sensitive cosmetic prepared by emulsifying a polyol with a specific nonionic surfactant, in order to obtain an appropriate viscosity and an excellent temperature-sensitive effect. Further, patent document 2 proposes that zeolite having high heat build-up is dispersed in a polyol solvent to improve the effect of imparting a temperature sensation.
As described above, various bases have been proposed as a temperature-sensitive cosmetic, and the cosmetic of patent document 1 is an oil-in-water type base and has a remarkably high slimy feeling because a polyhydric alcohol is directly in contact with the skin. Therefore, it is a rinse-off type cleanser used by being applied to the skin and rinsed after a certain time has elapsed. The cosmetic of patent document 2 is a Leave-on (Leave-on) type, but is nonaqueous, and therefore it is difficult to stably mix an aqueous solution containing a salt type drug having a cosmetic effect.
Therefore, there is a need for a water-in-oil base which can be blended with a cosmetic agent having a skin-beautifying effect such as a whitening component which exhibits an excellent effect of imparting a warm feeling and is excellent in stability and usability.

Problems to be solved by the invention
The purpose of the present invention is to provide a water-in-oil type temperature-sensitive cosmetic that exhibits an excellent temperature-sensitive imparting effect, has a good feeling of use, and has excellent storage stability.
Means for solving the problems
The present inventors have made extensive studies and, as a result, have found that the above object can be achieved by blending a polyol, an oil phase thickener, an emulsifier and water, and have completed the present invention.
That is, the present invention is a water-in-oil type temperature-sensitive cosmetic comprising:
a polyhydric alcohol,
An oil phase thickener,
An emulsifier, and
and (3) water.
ADVANTAGEOUS EFFECTS OF INVENTION
The temperature-sensitive cosmetic of the present invention exhibits an excellent temperature-sensitive imparting effect and also has excellent emulsion stability. Further, the temperature-sensitive cosmetic of the present invention is a water-in-oil type temperature-sensitive cosmetic, and can prevent the polyol from directly contacting the skin, so that the viscosity can be suppressed as compared with conventional oil-in-water or oil-in-polyol type temperature-sensitive cosmetics, although the humectant (polyol) is highly blended. Therefore, the temperature-sensitive cosmetic of the present invention can also be used as a leave-on type temperature-sensitive cosmetic base. In addition, a salt-type drug having a skin-beautifying effect such as a whitening component can be added because water can be added.
Detailed Description
The temperature-sensitive cosmetic of the present invention is characterized by containing a polyol, an oil phase thickener, an emulsifier and water as essential components. The present invention will be described in detail below.

The amount of the polyol to be blended in the cosmetic of the present invention is 20% by mass or more, preferably 20 to 80% by mass, and more preferably 30 to 70% by mass, based on the total amount of the cosmetic. If the amount of the polyol to be blended is less than 20% by mass, the feeling of warmth at the time of use cannot be sufficiently obtained.
< oil phase thickener >
The oil phase thickener used in the temperature-sensitive cosmetic of the present invention is one that can impart viscosity to an oil phase. By way of example, mention may be made of: emulsifying or non-emulsifying crosslinked silicone elastomer, dextrin fatty acid ester, hydrophobic modified polysaccharide, fatty acid, wax, etc. Among these, in the present invention, a non-emulsifying crosslinked siloxane elastomer is preferably used from the viewpoint of suppressing a sticky feeling.
The non-emulsifying crosslinked silicone elastomer is not particularly limited, and examples thereof include: methyl polysiloxane crosspolymer, methyl phenyl polysiloxane crosspolymer, vinyl dimethicone/lauryl dimethicone crosspolymer, lauryl dimethicone alkoxyethyl dimethicone/divinyl dimethicone crosspolymer, alkyl (C30-45) cetearyl dimethicone crosspolymer, and the like. These non-emulsifying crosslinked silicone elastomers are commercially available in the form of a swollen product that swells in various oil components such as silicone oil, mineral oil, glyceryl triisooctanoate, and squalane. Specific examples thereof include the following.
As the methylpolysiloxane crosslinked polymer, there can be mentioned: polydimethylsiloxane cross-linked polymers such as 9040 silicone elastomer blend, 9041 silicone elastomer blend, 9045 silicone elastomer blend and EL-8040ID silicone organic blend (manufactured by Dow Corning Toray Co., Ltd.), polydimethylsiloxane/vinyl polydimethylsiloxane cross-linked polymers such as KSG-15, KSG-16 and KSG-1610 (manufactured by shin-Etsu chemical Co., Ltd.), vinyl polydimethylsiloxane/polymethylsiloxane silsesquioxane cross-linked polymers such as KSP-100 (manufactured by shin-Etsu chemical Co., Ltd.), polymethylsilsesquioxane such as PEARL 150KA (manufactured by MoTOSE Performance Materials Co., Ltd.), and the like.

When the amount of the oil phase thickener added is 1.25% by mass or less, emulsion stability tends to be poor or usability tends to be poor, while when it is added in an amount exceeding 15% by mass, it may be difficult to produce a stable cosmetic.
The oil phase thickener of the present invention may be used in combination with one or more than 2 kinds selected from the aforementioned non-emulsifying crosslinked siloxane elastomers.
< emulsifier >
The emulsifier used in the temperature-sensitive cosmetic of the present invention is a relatively high lipophilicity and can exert an emulsion stabilizing effect of an aqueous component and an oily component highly blended with a polyhydric alcohol. In the present invention, polyether-modified silicone or organically modified clay mineral having specific properties can be preferably used.
The so-called polyether-modified silicone having the above-mentioned specific properties, which is used as the emulsifier of the present invention, is one having an HLB of 8.0 or less and a viscosity of 10000mm at 25 ℃2More than s, preferably 15000mm2A thickness of 20000mm or more2More than s. If the viscosity is less than 10000mm2And/s, good emulsion stability cannot be obtained.

The organically modified clay mineral used in the present invention is one of colloidal hydrous aluminum silicates having a three-layer structure, and a clay mineral represented by the following general formula (1) can be modified with a quaternary ammonium salt cationic surfactant.
(x，Y)2-3(Si，Al)4O10(OH)2Z1/3·nH2O (1)
In the formula, X is Al, Fe (III), Mn (III) or Cr (III), Y is Mg, Fe (II), Ni, Zn or Li, and Z is K, Na or Ca.
Specifically, the cationic surfactant can be obtained by treating clay minerals such as natural or synthetic smectites (in this case, those in which the (OH) group in the formula is substituted with fluorine) such as montmorillonite, saponite and hectorite (commercially available products such as magnesium aluminum silicate, Kunipia and synthetic hectorite), and synthetic micas (commercially available products such as Dimonite and manufactured by TOPY INDUSTRIES) known under the name of sodium silicate mica, sodium mica or laponite.
The quaternary ammonium salt cationic surfactant used here is represented by the following general formula (2).
In the formula, R1Represents C10-22 alkyl or benzyl, R2Represents a methyl group or an alkyl group having 10 to 22 carbon atoms, R3And R4Represents an alkyl group or a hydroxyalkyl group having 1 to 3 carbon atoms, and X represents a halogen atom or a methyl sulfate residue.

As shown in the results in the table, the composition containing the moisturizing agent, the oil phase thickener and the emulsifier of the present invention (example 1) can obtain a sufficient temperature-sensitive effect, and also has excellent emulsion stability, no sticky feeling and good feeling in use. Further, the compositions of examples 2 to 8 can be stably mixed with a whitening agent.
On the other hand, when the compositions containing no oil phase thickener (comparative examples 1 to 3) and the oil phase thickener were used in small amounts (comparative examples 4 and 5), the stability was remarkably lowered and separation occurred. In addition, the composition containing neither the polyether-modified silicone having a high viscosity nor the organic-modified clay mineral (comparative example 6) was remarkably low in stability. In addition, when the amount of water added is large (comparative example 7), a sufficient temperature effect cannot be obtained.
