Description

  The present invention relates to a two-part cosmetic that provides an esthetic effect in an esthetic massage treatment.

  In aesthetics, massage is one of the important treatments to improve skin metabolism by promoting blood circulation. However, there is a problem that the effect imparted greatly depends on the skill level of the practitioner. On the other hand, massage cosmetics used during treatment have been developed for the purpose of increasing the effect obtained by massage. It is important for such massage cosmetics to increase skin temperature and improve blood flow. Conventionally, many techniques for increasing the skin temperature utilize the heat of dissolution and heat of hydration of specific inorganic substances and organic compounds. For example, in the case of inorganic substances, sulfates, carbonates, chlorides, oxides and phosphates of mono- to trivalent metal ions are blended with zeolite and the like, and the heat of dissolution is used. In the case of organic compounds, polyhydric alcohols such as polyethylene glycol, glycerin and 1,3-butylene glycol, alkyl glycerides and the like are blended and the heat of hydration is utilized. Furthermore, in order to further increase these calorific values, a technique of combining an inorganic substance and an organic compound and imparting a warm feeling to the skin by an exothermic reaction with water in the skin (Patent Document 1), an inorganic salt / inorganic oxide The technology which improves exothermic property is made by making it the 2 agent type cosmetics which mix 1 agent containing oil, and 2 agents containing a polyhydric alcohol at the time of use (patent document 2).

  However, in these cosmetics, regardless of whether they are single-agent or double-agent, heat is generated by the water in the skin. Therefore, if the skin moisture is insufficient, the skin temperature cannot be improved and the esthetic effect is not satisfactory. It was enough. Further, when the skin surface was soiled with dirt, sebum, dust, etc., sufficient heat generation was not obtained, and skin temperature was not improved and blood flow was not promoted.

JP 2006-219465 A Japanese Patent Laid-Open No. 11-279031

  The object is to provide cosmetics that increase skin temperature, promote blood flow, increase skin moisture, and have excellent massage and esthetic effects during use. In particular, it is an object of the present invention to provide a cosmetic material having a good feeling of use without containing powder of an inorganic compound.

  The inventor uses a cosmetic composition containing a scrub agent as the first agent, 1 to 10% by weight of decaglycerin fatty acid ester eicosane diacid condensate, 80 to 99% by weight of polyhydric alcohol, and 0% of oil. Using a cosmetic composition containing 5 to 10% by weight and containing 5% by weight or less of water as a second agent for esthetic massage, increases skin temperature and improves blood flow As a result, the present inventors have found that the amount of moisture in the skin increases and the blood circulation of the face increases despite being applied to the body, and an excellent esthetic effect can be obtained.

  According to the present invention, after the skin is cleaned by massaging with the first agent containing a scrubbing agent and moderately given water, the decaglycerin fatty acid ester eicosane diacid condensate, polyhydric alcohol, and oil containing oil are contained. By massaging with two agents, skin temperature can be increased, blood flow can be improved / promoted, skin moisture can be increased, and an excellent esthetic effect can be obtained.

  Furthermore, by using an emulsified composition using mannan as a scrub agent as the first agent, the skin cleansing power can be increased and the massage effect can be enhanced. Further, by containing carboxyvinyl polymer, xanthan gum, or hydroxyethyl cellulose in the second agent, the viscosity is improved and the staying property on the skin is increased, so that the sustainability of the temperature rise can be further increased. In addition, by using glycerin, 1,3-butyne glycol as polyhydric alcohol, and squalane, squalene, olive oil, jojoba oil, squalane, squalene, cyclomethicone, and dimethylpolysiloxane as oil components, the skin moisture content is increased and the esthetic effect is enhanced. Further improvement can be achieved.

  When the present invention is applied to the upper body other than the face (for example, the chest, neck, shoulders, back, etc.), blood circulation is promoted to increase the skin temperature of the face. Therefore, even when used as a body, a face care effect can be expected.

  The present invention relates to a cosmetic composition containing a scrub agent as a first agent, and a cosmetic containing a desired amount of a decaglycerin fatty acid ester eicosane diacid condensate, a polyhydric alcohol and an oil as a second agent. It consists of a composition.

  The scrub agent used for the first agent is not particularly limited, but it is desirable to provide an appropriate massage effect when cleaning the skin. Specifically, examples of natural scrubs include polysaccharide particles such as mannan, agar, alginate, chitin, chitosan, ground nuclides such as walnut shells and peach species, peanut powder such as peanuts and sesame seeds, and casein. Of protein powder. Examples of the synthetic polymer scrub include particles of synthetic resin such as polyethylene, polypropylene, polyester, polystyrene, polyurethane, and silicon powder. These can be used alone or in combination of two or more. Among these, mannan, agarite, and alginates are particularly preferable as the scrub agent in the first agent. Mannan, agar, and alginates are gels containing moisture, so they have a soft feel and a high massage effect such as promoting blood circulation in the skin.

  In particular, mannan is more preferable because it has a high skin massage effect. Mannan is obtained by refining from konjac koji and is also called glucomannan. Preferably, it is a mannan gel product obtained by gelling mannan. Mannan is uniformly blended into the first agent in a granular form, and can maintain a granular shape without being dissolved or crushed during use, and can provide a scrub effect. Commercial products of Mannan include Propol ISLB, White Propol ISLB (Shimizu Chemical Co., Ltd.) and the like.

  The scrub agent is preferably added to the first agent in an amount of 0.1 to 10% by weight, more preferably 0.5 to 5% by weight, and still more preferably 1 to 3% by weight. If it is less than 0.1% by weight, the scrubbing force is not sufficient, and if it exceeds 10% by weight, the feeling of use becomes worse.

  The content of water in the first agent is preferably 10 to 50% by weight, and more preferably 20 to 40% by weight. By setting the amount of water in the first agent to an appropriate amount, the heat generation effect of the second agent can be enhanced. If the water content is less than 10% by weight, water supply to the skin is reduced, and water for heat generation is insufficient when the second agent is used, resulting in a decrease in heat generation. On the other hand, if the content of water is more than 50% by weight, the amount of water is too large, and the exothermicity when using the second agent is lowered. In any case, the effect of increasing the skin temperature is reduced.

  The cosmetic composition for the first agent is preferably a cleaning composition, and the dosage form is an emulsified composition or an aqueous composition (solubilized composition based on water) having the effect of imparting cleansing and moisture. Is preferred. Among these, the emulsified composition is more preferable because it cleanses the skin and gives sufficient moisture to improve the esthetic effect of the second agent.

  The oil component used when the first agent is an emulsified composition is not particularly limited, but hydrocarbons such as squalane, squalene, ceresin, olefin oligomer, liquid paraffin, olive oil, jojoba oil, avocado oil, almond oil, grape seed oil , Evening primrose oil, corn oil, camellia oil, sasanqua oil, macadamia nut oil, medfoam oil, shea butter, sesame oil, rice bran oil, egg yolk oil and other oils, isostearyl alcohol, octyldodecanol, lanolin alcohol, phytosterol, oleyl alcohol Higher alcohols such as glyceryl tri-2-ethylhexanoate, isopropyl myristate, ethyl oleate, octyl stearate, cetyl 2-ethylhexanoate, isononyl isononanoate, octyl palmitate, ethyl dioleate Ester oils such as glycol, glyceryl triisostearate, cetyl lactate, diisopropyl adipate, isostearyl isostearate, dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified polysiloxane, amino-modified polysiloxane, epoxy-modified polysiloxane, Fluorine-modified polysiloxane, alcohol-modified polysiloxane, alkyl-modified polysiloxane, silicones such as polymer silicone, lauric acid, myristic acid, palmitic acid, stearic acid, behen (behenine) acid, oleic acid, 12-hydroxystearin And higher fatty acids such as acid, undecylenic acid, toluic acid, isostearic acid, linoleic acid, linolenic acid, eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). One or two or more selected from these can be used in combination. The amount of oil is preferably 30 to 90% by weight, more preferably 40 to 80% by weight, and still more preferably 50 to 70% by weight. If it is less than 30% by weight, the sustainability of heat generation cannot be sufficiently exhibited, and if it exceeds 10% by weight, the stability of the preparation is deteriorated.

  Among the above, the oil component in the first agent is preferably at least one of glyceryl tri-2-ethylhexanoate and an olefin oligomer. Glyceryl tri-2-ethylhexanoate is a polar liquid oil, and can increase the cleansing power in the first agent. Another name is trioctanoin. As a commercial item, T.I.O (Nisshin Oillio Co., Ltd.) etc. are mentioned. Glyceryl tri-2-ethylhexanoate is preferably blended in the first agent in an amount of 1 to 80% by weight, more preferably 5 to 50% by weight, and even more preferably 10 to 30% by weight. If it is less than 1% by weight, the cleansing power is not sufficient, and if it exceeds 80% by weight, the feeling of use becomes worse.

  The olefin oligomer is an oil that is liquid at room temperature, and can increase the cleansing power of the first agent. As the olefin oligomer, an α-olefin oligomer is preferable. The average molecular weight is preferably 500 to 5,000. Examples of commercially available olefin oligomers include Puresyn 40, Puresyn 100, Puresyn 150, Puresyn 300, Puresyn 1000 (Exxon Mobil) and Synthelan 4 (Nikko Chemicals). The olefin oligomer is preferably blended in the first agent in an amount of 1 to 80% by weight, more preferably 5 to 50% by weight, and still more preferably 10 to 30% by weight. If it is less than 1% by weight, the cleansing power is not sufficient, and if it exceeds 50% by weight, the feeling of use becomes worse. When the oil component of the first agent contains both glyceryl tri-2-ethylhexanoate and an olefin oligomer, the weight ratio is preferably 1: 5 to 5: 1. By using this weight ratio, the cleansing force can be increased.

  Examples of the surfactant include polyoxyethylene coconut oil fatty acid glycerin, polyoxyethylene hydrogenated castor oil, and polyglycerin fatty acid ester.

  When the first agent is an aqueous composition, the oil is preferably solubilized. The surfactant used for solubilization is not particularly limited, and examples thereof include polyoxyethylene coconut oil fatty acid glycerin, polyoxyethylene hydrogenated castor oil, and polyglycerin fatty acid ester. The oil content is not particularly limited, and examples thereof include liquid oils such as squalane, squalene, olefin oligomer, liquid paraffin, olive oil, jojoba oil and macadamia nut oil.

  The decaglycerin fatty acid ester eicosane diacid condensate used in the second agent of the present invention is a condensate of glycerin having an average polymerization degree of 2 or more, a linear saturated fatty acid having 18 to 28 carbon atoms, and 20 to 28 carbon atoms. The esterification product of an aliphatic saturated dibasic acid. English name: POLYGLYCERYL-10 BEHENATE / EICOSADIOATE, also known as: (behenic acid / eicosanedioic acid) polyglyceryl-10. Specific examples of commercially available products include NOMCOAT HK-P (Nisshin Oilio Co., Ltd.). The amount of decaglycerin fatty acid ester eicosane diacid condensate is preferably 1 to 10% by weight, more preferably 2 to 8% by weight, and even more preferably 3 to 5% by weight. If it is less than 1% by weight, the sustainability of heat generation is not sufficiently exhibited, and if it exceeds 10% by weight, the usability as a cosmetic becomes worse.

  The polyhydric alcohol used for the second agent is not only used as a base, but also has an effect of generating heat when mixed with water. Polyhydric alcohols are known to generate heat upon contact with water, but in the present invention, exothermic properties are improved by the combined use with decaglycerin fatty acid ester eicosane diacid condensate and oil. The type of polyhydric alcohol is not particularly limited. For example, glycerin, 1,3-butyne glycol, 1,2-pentanediol, polyethylene glycol, propylene glycol, dipropylene glycol, polypropylene glycol, hexylene glycol, glycerin, diester Examples include glycerin. Preferred are glycerin, 1,3-butyne glycol, polyethylene glycol, propylene glycol, and dipropylene glycol, and more preferred are glycerin and 1,3-butyne glycol. One or two or more selected from these can be used in combination.

  In the second agent, the blending amount of the polyhydric alcohol is 80 to 99% by weight, preferably 85 to 98% by weight, and more preferably 90 to 96% by weight. If it is less than 80% by weight, the heat generation effect is not sufficient, and if it exceeds 99% by weight, the feeling of use of the cosmetic is impaired.

  The oil component used in the second agent is not particularly limited, but hydrocarbons such as squalane, squalene, ceresin, olefin oligomer, liquid paraffin, olive oil, jojoba oil, avocado oil, almond oil, grape seed oil, evening primrose oil, corn Oil, camellia oil, sasanqua oil, macadamia nut oil, medofoam oil, shea butter, sesame oil, rice bran oil, egg yolk oil and other fats, isostearyl alcohol, octyldodecanol, lanolin alcohol, phytosterol, oleyl alcohol and other higher alcohols Glyceryl tri-2-ethylhexanoate, isopropyl myristate, ethyl oleate, octyl stearate, cetyl 2-ethylhexanoate, isononyl isononanoate, octyl palmitate, ethylene glycol dioleate, Ester oils such as glyceryl lyisostearate, cetyl lactate, diisopropyl adipate, isostearyl isostearate, cyclomethicone, dimethylpolysiloxane, methylphenylpolysiloxane, polyether-modified polysiloxane, amino-modified polysiloxane, epoxy-modified polysiloxane , Fluorine-modified polysiloxane, alcohol-modified polysiloxane, alkyl-modified polysiloxane, silicones such as high molecular silicone, lauric acid, myristic acid, palmitic acid, stearic acid, behenic acid, oleic acid, 12-hydroxy Higher fatty acids such as stearic acid, undecylenic acid, toluic acid, isostearic acid, linoleic acid, linolenic acid, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), etc. . Preferably, squalane, squalene, olive oil, jojoba oil, cyclomethicone, and dimethylpolysiloxane are used. One or two or more selected from these can be used in combination. The blending amount of oil is preferably 0.5 to 10% by weight, more preferably 0.7 to 5% by weight, and further preferably 1 to 3% by weight. If the amount is less than 0.5% by weight, the persistence of heat generation cannot be sufficiently exhibited, and if the amount exceeds 10% by weight, the stability of the preparation is deteriorated.

  The content of water in the second agent is 5% by weight or less, preferably 3% by weight or less, more preferably 2% by weight or less. If it exceeds 5% by weight, the exothermicity is not sufficient. The water content affects the heat generation effect, and a smaller content is preferable because heat generation and heat generation persistence are improved. Therefore, it is more preferable that the water content is substantially 0% by weight, that is, a non-aqueous cosmetic composition is used. Here, “substantially 0% by weight” means that some cosmetic raw materials such as liquid polyhydric alcohols contain moisture, so that the water content is completely 0% by weight. Although it cannot, it means that water other than the water contained in the raw material is not blended.

  The second agent can further increase the sustainability of heat generation by containing at least one selected from carboxyvinyl polymer, xanthan gum, and hydroxyethyl cellulose. The blending amount of at least one selected from carboxyvinyl polymer, xanthan gum and hydroxyethyl cellulose is preferably 0.1 to 1% by weight, more preferably 0.2 to 0.5% by weight. If it is less than 0.1% by weight, the sustainability of heat generation cannot be sufficiently exhibited, and if it exceeds 1% by weight, the viscosity of the preparation becomes high and the feeling of use of the cosmetics is deteriorated.

  The second agent is preferably a gel cosmetic composition. By making it into a gel, it is easy to apply to the skin, and the applied cosmetic composition is held on the skin for a long time, so the durability of the heat generation effect can be further enhanced. Moderate fever on the skin can impart an esthetic effect and a massage effect, and can be a cosmetic that is particularly suitable for caring for the chest (decorte), neck and back.
