Description

  The present invention relates to a water-in-oil emulsion composition having a fresh feeling of use and good emulsion stability.

  The emulsified compositions are roughly classified into an oil-in-water type (O / W) and a water-in-oil type (W / O), and further, an oil-in-water type (O / W / O), a water-in-oil-in-water type ( There are also multiple types such as (W / O / W). These are conventionally used in skin care creams, emulsions, massage creams, make-up removal creams, hair care creams and the like in the cosmetics field, and as transdermal creams in the pharmaceutical field.

  Among these, the water-in-oil (W / O) emulsion composition in which the oil phase is the outer phase and the water phase is the inner phase is efficient in using oil-soluble active ingredients such as emollient oil, oil-soluble drugs, and UV absorbers. Since it can be developed on the skin, it is a dosage form suitable as an external preparation for skin, and is superior to the oil-in-water type in this respect.

In general, it is considered that it is difficult to ensure stability of a water-in-oil emulsion composition as compared with an oil-in-water emulsion composition (for example, see Non-Patent Document 1).
If this is an oil-in-water emulsified composition, the polyoxyethylene alkyl surfactant, which is widely used as a nonionic surfactant, is used to emulsify the entropy repulsion of the polyoxyethylene chain and the electrostatic repulsion of the ionic surfactant. In the case of water-in-oil emulsion compositions, lipophilic surfactants that are considered suitable for preparation tend to be less hydrophilic (oleophobic). This is related to factors such as the fact that the surfactant to be adsorbed on the interface is consumed in a monodisperse form dissolved in the oil phase, making it difficult to stabilize the oil-water interface efficiently. Therefore, in a water-in-oil emulsion composition, stabilization is achieved by blending a polymer compound or gelling a large amount of a surfactant in order to gel the oil constituting the outer phase and immobilize water droplets. In many cases, the amount and type of emulsifier, the ratio of the internal water phase, the type and amount of the aqueous component, the type and amount of oil, the type and amount of other stabilizers were limited.

  In general, the water-in-oil type emulsion composition has a drawback that it is refreshed compared to the oil-in-water type emulsion composition because the outer phase is an oily component. In order to solve such drawbacks, generally, a technique for increasing the proportion of the aqueous component in the inner phase, a technique for increasing the volatile oil content in the oil component in the outer phase, and the like are taken. However, increasing the internal phase ratio causes deterioration in emulsion stability, and increasing the volatile oil content decreases the skin care effect because the residual oil content having a skin care effect decreases.

  From the above, in the skin care cream utilizing the water-in-oil emulsion composition, it has been difficult to maintain a good stability while having a fresh feeling of use and a high skin care effect.

  From such points, water-in-oil emulsified cosmetics with high stability have been developed by using polyether-modified silicone as an emulsifier (see, for example, Patent Document 1 and Patent Document 2). In this method, it is recommended to use a polyether-modified silicone having a high molecular weight (30000 or more). However, the polyether-modified silicone usually exhibits a behavior as a polymer surfactant and gives a sticky feeling of use due to entanglement of polymer chains. In addition, the stability of a water-in-oil emulsified cosmetic using polyether-modified silicone as an emulsifier decreases as the internal phase ratio increases. From the above, it has been difficult to provide a water-in-oil emulsified cosmetic using a polyether-modified silicone as an emulsifier, having a fresh feeling of use.

  In addition, a water-in-oil emulsion composition having a high internal water phase ratio obtained by using a partially hydrophilized crosslinked polysiloxane and applied to cosmetics is also known (see Non-Patent Document 2, for example). . The water-in-oil emulsion composition obtained by this method is characterized by a fresh feeling of use due to a high internal phase ratio. However, when preparing an emulsion by this method, there has been a problem that the emulsion composition is easily destabilized by blending oil other than cyclic silicone, nonpolar oil, polar oil, linear silicone and the like. Therefore, there are many restrictions on the use of oil, and it has been difficult to obtain a high skin care effect.

As described above, it has been difficult to provide a water-in-oil emulsion composition having a good stability and good stability while having a fresh feeling of use and a high skin care effect by the conventional methods.
The present invention has been made in view of the above-mentioned problems of the prior art, and has a fresh feeling of use due to a high internal water phase ratio and an emulsion stability while being a water-in-oil emulsion composition having a high skin care effect on the skin. The object is to provide a water-in-oil emulsion composition having good properties.

  As a result of intensive studies to solve the above-mentioned problems, the present inventors have found that a water-in-oil emulsion composition containing a specific component has good emulsification stability and a fresh feeling of use. As a result, the present invention was completed.

The present invention is a water-in-oil emulsion composition comprising the following components (A), (B), and (C), and further satisfying the following conditions (i) to (iii):
(A) One or more selected from glyceryl monooleate, glyceryl monoisostearate and polyoxyethylene glyceryl monoisostearate (B) Aqueous component (C) Oil component condition including solid oil:

(Iii) The solid oil content in the component (C) is 3 to 70% by mass with respect to the component (C).

  The water-in-oil emulsified composition according to the present invention has good emulsion stability and a fresh feeling to use. Moreover, the skin care effect with respect to skin is also high.

The best mode of the present invention will be described below.
The water-in-oil emulsion composition according to the present invention comprises (A) one or more selected from glyceryl monooleate, glyceryl monoisostearate and polyoxyethylene glyceryl monoisostearate, (B) an aqueous component, (C) It is comprised from the oil-based component containing a solid oil component. Hereinafter, each component will be described in detail.

(Ingredient (A))
The component (A) used in the present invention is one or more selected from glyceryl monooleate, glyceryl monoisostearate and polyoxyethylene glyceryl monoisostearate.
Of these, glyceryl monooleate (A-1) can be provided by various known synthetic methods. According to the usual synthesis method, it is produced as a mixture of glyceryl monooleate, glycerin dioleate, and glyceryl trioleate. The component (A) glycerin monooleate constituting the water-in-oil emulsion composition according to the present invention preferably has a high purity, and preferably has a pure content of 90% or more. As a purification method of glyceryl monooleate, a molecular distillation method is usually used, but is not limited thereto. For example, it is marketed as “MONOMULS90-O18 (manufactured by KOGNIS)”, and these can be suitably used.

  Glycerol monoisostearate (A-2) is commercially available, for example, as “EMALEX GWIS-100EX (manufactured by Nippon Emulsion Co., Ltd.)”, “NIKKOL MGIS (manufactured by Nikko Chemicals)”, etc. it can.

  Polyoxyethylene glyceryl isostearate (A-3) is glyceryl isostearate having polyoxyethylene in the molecular structure. The number of moles of the polyoxyethylene chain is preferably less than 7, and if it is 7 or more, the hydrophilicity of the component (A) as a mixture increases, which is inappropriate for the preparation of a water-in-oil emulsion composition. Examples of polyoxyethylene glyceryl isostearate are commercially available as “EMALEX GWIS-103EX (manufactured by Nippon Emulsion Co., Ltd.)”, “EMALEX GWIS-105EX (manufactured by Nippon Emulsion Co., Ltd.)”, etc., and these are preferably used. be able to.

As a component (A), 1 type, or 2 or more types of the (A-3) component from the said (A-1) component can be selected in the range which does not impair stability. From the viewpoint of emulsification stability, the (A-2) component and the (A-3) component are water-in-oil emulsification having higher emulsification stability as compared with the case where the component (A-1) is used alone. The composition cannot be prepared. On the other hand, the water-in-oil emulsion composition prepared using the component (A-1) alone has a risk of crystal precipitation at a low temperature. Moreover, emulsification stability improves by using combining (A-2) component and (A-3) component.
Therefore, in preparing a water-in-oil emulsion composition that is actually stable at a wide range of temperatures, it is preferable to use two or more components (A-1) to (A-3) in combination.

  In this invention, it is preferable that the compounding quantity of an aqueous component is 70-98 mass% with respect to the whole composition, More preferably, it is 75-90 mass%. When the aqueous component is less than 70% by mass, freshness is lost only at the time of application, and when it exceeds 98% by mass, the emulsion stability is lowered.

As is apparent from the results shown in Table 1, stability is achieved by using one or more kinds selected from glyceryl monooleate, monoisosteeric glycerin, POE (5) glyceryl monoisostearate as surfactants. In addition, a water-in-oil emulsion composition having high usability and skin care effect could be prepared. (Examples 1-4). Further, when the pure content of glyceryl monooleate used as the surfactant is less than 90% (Example 5), the case of 90% or more (Example 2) has a higher emulsification stability and the water-in-oil type. An emulsified composition can be prepared.
When the amounts of surfactant glyceryl monooleate and POE (5) glyceryl monoisostearate are large (Comparative Example 1) or when the internal phase ratio is low (Comparative Example 2), the fresh feeling of use is lost. Further, as shown in Comparative Example 3, when no solid oil is used as the oil, the emulsion stability and the skin care effect are lowered.
When alkyl / polyether co-modified silicone is used as a surfactant (Comparative Examples 4 and 5), it is difficult to achieve both feeling of use and emulsion stability, and when a cross-linked polyether-modified silicone is used as a surfactant In Comparative Examples 6 and 7, it is difficult to achieve both skin care effect and emulsion stability.

  As shown in Table 2, the average number of added moles of the polyoxyethylene moiety in the polyoxyethylene glyceryl monoisostearate used as the surfactant is less than 7 compared to the case of 7 or more (Example 7) ( In Examples 2 and 6), a water-in-oil emulsion composition having higher emulsion stability can be prepared.

  As shown in Table 3, by using two or more kinds selected from glyceryl monooleate, monoisosteeric glycerin, and POE (5) glyceryl monoisostearate as surfactants (Examples 2 and 8), the above interface It was possible to prepare a water-in-oil emulsion composition having higher emulsification stability as compared with the case where each activator was used alone (Examples 9 to 11).

  As shown in Table 4, by using petrolatum as the oil component (Example 2), it is possible to prepare a water-in-oil emulsion composition having a higher skin care effect than when not using (Example 12). did it.

As shown in Table 5, when compared to the case of using a microcrystalline wax having a high hardness at normal temperature as a solid oil component in the oil phase component (Example 16), paraffin wax and paraffin wax having a low hardness at normal temperature In the case of using a mixture of microcrystalline wax (Examples 2 and 13 to 15), the familiarity with the skin is good.
In addition, even when microcrystalline wax is used as the solid oil component, the blending of dextrin palmitate, inulin stearate, and glyceryl behenate eicosane diacid lowers the hardness of the oil phase component, so the skin familiarity is good. (Examples 17 to 19).
Further, when the amount of the solid oil in the oil phase component is large (Comparative Example 8), since the hardness of the outer phase becomes too high, the familiarity with the skin is deteriorated.
