Description

Oily solid cosmetic

Present invention relates to a phospholipid composition comprising 25 to 42% of the lines phosphatidyl choline, 25 to 42% of phosphatidyl ethanolamine (component (A)), having 1 ~ 100mm ² / s dynamic viscosity of the silicone oil (ingredient at 25 deg.] C ( b)) Oily ester oil (ingredient (c)) at 25 ° C, component (b) and component (c) containing an oily solid with a mass ratio (b) / (c) of 0.006 ~ 0.4 In more detail, it is an oily solid cosmetic which is excellent in spreadability when the finger is taken and used, has less stickiness after application, and has excellent stability and high moisturizing effect.

The phospholipid system is generally used as an ecologically relevant component, and is excellent in skin application, and is widely used in the field of cosmetics, and is particularly useful as a dispersing agent or an emulsifier, a moisturizing agent, and an antioxidant (for example, refer to Non-Patent Document 1). In addition, eucalyptus oil, especially low-viscosity eucalyptus oil, is used in various applications due to its excellent gloss, progress, refreshing, lubricity, water repellency, safety, etc., and is also mostly used in cosmetics (for example, reference non-patent) Literature 2).

A general oily solid cosmetic is a wax component such as a fat or oil such as cocoa butter or wood wax, a wax such as carnauba wax or cetacean, a paraffin wax or a microcrystalline violet wax, and the oil component is solidified. Further, a technique in which dextrin fatty acid fat is used as an oil gelling agent is known, unlike these wax components. For example, a solid oily component such as a combination of a dextrin fatty acid fat and a paraffin wax, and an oily solid cosmetic material of a liquid oil (for example, refer to Patent Document 1), a combined dextrin fatty acid fat, a heavy flow isoparaffin, and a liquid. The technique of an oily component (for example, refer to Patent Document 2).

However, in the technique of Patent Document 1, it is not preferable in terms of usability by blending a solid oil. Further, in the technique of Patent Document 2, there are problems in usability or storage stability, and it is sticky after application. In addition, with such techniques, the fingers are not easy to take the cosmetic material, and it is also difficult to spread or sticky when applied to the skin.

On the other hand, as described above, since the eucalyptus oil has various excellent properties, the technique of containing eucalyptus oil in the oily solid cosmetic is reviewed. For example, a technique for combining a dextrin fatty acid ester and a solid cosmetic having a liquid chain hydrocarbon, a sterol derivative, and a methylphenyl polyoxyalkylene having an average carbon number of 40 to 200 (for example, refer to Patent Document 3) , using a three-dimensional crosslinked structure of an organic polyoxyalkylene polymer, or propylene. A technique of a polyoxyalkylene-based cross-linked copolymer (for example, refer to Patent Documents 4 and 5), a technique of combining a fluorinated acid amide compound, a hydrocarbon oil, and a gel-like cosmetic of eucalyptus oil (for example, refer to Patent Document 6). Further, among the above phospholipids, a technique in which a hydrogenated phospholipid is used as an oil gelling agent (for example, refer to Patent Document 7) or a technique in which inulin stearate is used as a gelling agent for an emu oil (for example, refer to Patent Document 8).

However, in the technique of Patent Document 3, similarly to the above-mentioned Patent Documents 1 and 2, problems such as the useability of the fingers or the application of the coating or the storage stability are caused, and the feeling of stickiness after application is felt. In the techniques of Patent Documents 4 to 5, since the miscibility of the eucalyptus oil and other oily components is poor, a sufficient viscosity-increasing effect cannot be obtained, and it is difficult to obtain a stable gelled composition. Further, although the technique of Patent Document 6 is directed to a novel gelling agent technique, it is still insufficient for finger picking. Further, in the technique of Patent Document 7, although the moisturizing effect is excellent, the phospholipid is used in a large amount, and the spreadability is poor. In addition, when the phospholipid is actually 40% or less of the total composition, it is necessary to use a wax component for curing the oil. Therefore, it is difficult to take the cosmetic with a finger, and if it is contained, it is used to improve the sticky feeling. When the oil is simmered, the preservation stability will be deteriorated. Further, although the technique of Patent Document 8 relates to a cosmetic material which gels volatile eucalyptus oil, although the usability is excellent, the moisturizing effect is still insufficient.

As described above, the oily solid cosmetic in the above-mentioned conventional technique mainly uses a solid oil or an oil gelling agent, and it is difficult to improve the oily component, and it is difficult to improve the handling of the finger as a cosmetic material, or the spreadability is poor. In particular, when the eucalyptus oil is used to improve the spreadability, since the mutual solubility is poor depending on the type of the oily component, or the viscosity-increasing effect or gelation ability is insufficient, it is found that the viscosity of the preparation is lowered or the oil is exuded from the gel. The number of effective things called "liquid discharge" is less than the truth. In addition, although various reviews have been conducted on the gelling agent, it has not yet been obtained from the use or storage stability. Therefore, it is required to develop an oily solid cosmetic which is excellent in the smear of the eucalyptus oil or which does not feel a good feeling of stickiness after application, and which is easy to handle, and which has excellent stability and moisturizing effect.

The present invention is to provide a method for stably blending eucalyptus oil into an oily solid cosmetic material without using a solid oil component or the like, thereby providing a finger holding and excellent spreadability, and the cosmetic material is not sticky after application. It is a problem that it is greasy and further preserves an oily solid cosmetic which is excellent in stability and moisturizing effect.

According to the facts of the present inventors, it has been found that a finger of a specific composition can be obtained by combining a phospholipid having a specific composition, an eucalyptus oil having an kinetic viscosity of 1 to 100 mm ² /s at 25 ° C, and a liquid ester oil at 25 ° C. The invention is excellent in handling and smearing, and is not sticky after applying the cosmetic material, and further preserves an oily solid cosmetic having excellent stability and moisturizing effect.

That is, the present invention relates to the following components (a) to (c):

(a) 5 to 25% by mass of phospholipids, phospholipid composition 25 to 42% phospholipid choline, 25 to 42% phospholipid ethanolamine

(b) Emu oil with a dynamic viscosity of 1 to 100 mm ² /s at 25 ° C

(c) Liquid ester oil at 25 ° C

And the component (b) and the component (c) have an oily solid cosmetic having a mass ratio (b)/(c) of 0.006 to 0.4.

The component (c) is an oily solid cosmetic characterized by a branched fatty acid having a carbon number of 6 to 30 and a triglyceride oil of glycerin.

The component (c) is an oily solid cosmetic characterized by 2-ethylhexanoic acid glyceride and/or triisostearic acid glyceride.

It is an oily gel-like cosmetic characterized by further containing 5 to 20% by mass of the component (d) N-mercaptolysine.

The oily solid cosmetic material is obtained by filling the components (a) to (c) which are melted at 70 to 80 ° C in a container and cooling them.

The oily solid cosmetic of the present invention is excellent in finger pick-up or spreadability, has less stickiness, and is excellent in preservation stability and moisturizing effect.

The best form for implementing the invention

The invention is described in detail below.

The phospholipid of the component (a) of the present invention is used as an oil solidifying agent in an oily solid cosmetic, and the phospholipid type is not particularly limited as long as it is a user of a general cosmetic, for example, for example, A soybean-derived phospholipid, a soybean-derived hydrogenated phospholipid, an egg yolk-derived phospholipid, an egg yolk-derived hydrogenated phospholipid, These phospholipids are generally a mixture of phospholipid choline (hereinafter abbreviated as PC), phospholipid ethanolamine (hereinafter abbreviated as PE), phospholipid myoinositol (hereinafter abbreviated as PI), etc., and the composition varies depending on the source of the phospholipid, but The phospholipid phospholipid composition used in the present invention is composed of 25 to 42% of PC and 25 to 42% of PE. In this range, it will be a cosmetic which retains an oily solid which is excellent in stability. In the case of phospholipid composition, less than 25% of PCs have poor compatibility with oil agents, and more than 42% cannot function as oil gelling agents. In addition, those with less than 25% of PE in the phospholipid composition will be difficult to operate as oil gelling agents, and if more than 42% are poorly miscible with oil agents.

(Production method)

A: The composition was heated to 80 °C.

B: Mix A with a dispersing mixer.

C: Filled with B (80 ° C) in a container and cooled to room temperature to obtain a solid cream.

(moisture evapotranspiration test)

For the solid cream of the invention product 9 and the comparative product 12 to 14, the occlusion property was examined. These solid creams were uniformly coated on a polyvinyl chloride film of a Franz-type diffusion tank placed in a 0.9% NaCl aqueous solution using a doctor blade, and the coating amount was 0.2 g, and the coated area was applied. It is 8.03 cm ² and has a thickness of 40 μm.

Eight hours after the start of the measurement, the change in the weight of the tank was measured, and the cumulative water permeation amount was used to calculate the water evapotranspiration rate per 1 m ² per hour by the following formula. Further, the presence or absence of solidification was evaluated in the same manner as in Example 1. The results are shown in Table 4.

Water evapotranspiration rate (g/hr.m ² ) = (cumulative moisture permeation amount (g) / time (hr)) × (100 × 100 / 8.03)

Since the moisture evapotranation rate of the present invention is extremely low, the occlusion property is high and the moisturizing effect is excellent. On the other hand, the gel 12 was not formed using the comparative product 12 having a different phospholipid composition. Further, the comparative products 13 and 14 which use an oil gelling agent other than the phospholipid are high in water evapotranspiration and low in occlusive property.

(measuring friction stress)

CSL type pressure-controlled rheometer (cone is 4cm 2°, measuring temperature is 15°C), straight line drawn from the origin of shear rate (Shear rate) and shear stress (Shear Stress) curve, and the deviation point is measured. Shear stress. The result is shown in Figure 1. In addition, the needle load value was measured by a rheometer (FUDOH RHEOMETER NRM-2002D: manufactured by Immobilisation Co., Ltd.) (φ 1.0 mm, d = 2 mm, 6 cm/min, 35 ° C, 1 hour).

As can be seen from Fig. 1, even if the same needle load is applied, the comparative product 15 has a hard crystal structure and requires a strong force to break the crystal structure. On the other hand, in the product 9 of the present invention, the gel was broken by weak frictional stress, so that the smooth spreadability was exhibited.

Further, a scanning electron micrograph of the gel of the present invention 9 is shown in Fig. 2 . From this photograph, it is shown that the gel of the present invention 9 is a layered lamella liquid crystal. It is presumed that since the lamellar liquid crystal is formed in such a layer, the moisture evapotranspiration is suppressed as described above, and the gel is broken by weak frictional stress, and the spreadability is good.

(Functional assessment)

For the gels of the invented products 9 to 10 and the comparative products 11 to 12, 20 were used as the assessors, and applied to the face, (a) spreadability after application, and (b) tension after application. The feeling and (c) the moisturizing effect were evaluated according to the (A) five-stage evaluation criteria, and the score average score of each sample was determined using the (B) four-stage determination standard.
