Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is mainly used in the field of cosmetics, and in this field, a pack agent means that when the pack agent is applied to the face or body part and the dirt attached to the skin surface is removed. At the same time, it is applied in anticipation of the cosmetic effect brought about by applying or absorbing the blended active ingredient to the skin.

[0002]

2. Description of the Related Art Packing agents are commercially available as powders or viscous bodies, and in the case of powders, consumers add water to make them viscous bodies, or they are heated and applied to the skin surface for a temporary cleaning. After it has had an effective effect, it is removed. The method of this removal is to wash away with water as usual, and at that time, there is a type in which the packing agent is solidified and peeled off, and a pull-off type in which a thin film is formed and peeled off.

The method of removing the pack agent of the present invention after application is as follows:
If you rub the surface of the skin for a while after applying this, it will look like plaque, and will fall off like rubbish residue of just an eraser (dart off). This peculiar phenomenon is available on the market as a type of emollient cream that removes keratinous skin such as elbows and knees.

[0004]

The obsession with women's beauty is crazy, and various cosmetics for satisfying the desire are disclosed in various ways, and the same applies to packs. Probably effective substances for beautiful skin ... From super-specialized chemical products to superstitious natural substances ... are mixed and applied to a soft mud-like base to apply the skin-softening ingredients to the skin. It is supposed to be possible. Certainly, there are many points that it can be speculated that the packs are more effectively absorbed through the skin than other cosmetics. What happens is that the action of the drug is limited to the contact surface in the case of simply applying a lotion, whereas it is undeniable that the combined use of a massage with a pack can be further enhanced.

To this end, the present inventor has conceived that a dirt-off type pack agent is suitable, but when formulating an effective cosmetic component for skin beautifulness, a problem has arisen in the concrete formulation thereof. That is, "water" is the first requirement for maintaining the aesthetic health of the skin, and "oil" is the second.
Next is "nutrition". In the pack of the present invention, in order to supply these "water", "oil", "nutrition", and "waste"
That is, it contains "powder" for removing "dirt". However, in the conventionally known emollient cream, since the main object is to remove waste products and there is no consideration for such skin beautification, the skin after application is not smooth and tends to be dry. By the way, if an oily component is simply added to this known formulation, separation and formation of the dirt are unsatisfactory, resulting in an unsatisfactory problem.

[0006]

As a means for solving the problems, the present inventor has conducted a number of experiments, and the conclusions reached are as follows. That is, the compounding ingredient is C: crystalline cellulose powder. B: Various powders. P: Powder component. = (C + B) A: Oily component. E: Ethanol component. D: Additive component. , W: Water component. M: Stock solution [in the case of aerosol]. = (C + B + A + E +
D + W) X: Ejection agent. When expressed by, the quantitative relationship is (I) in viscous gel type (soft mud) / (II) in aerosol type B = “0.02-1” × C Same as left A = “0.02-0 .5 "× P Same as left D =“ 0-0.25 ”× total amount Same as left E =“ 0.04-0.5 ”× (P + A)“ 0.04-1.0 ”× (P + A) W = “1 to 100” × P “2 to 200” × P X = −− “0.06 to 0.36” × M. Note), "x to y" in the above formula indicates a numerical value in the range of x to y.

The packs of the present invention are classified into (a) gel (soft mud) type and (b) aerosol type. When both are applied on the skin, they are initially in the form of a viscous mud containing water (the aerosol type also has a foamy form),
When kneading without rubbing (massaging) with the palm of your hand, the moisture gradually evaporates and solidifies, becoming like a “pure” that has been twisted (hereinafter referred to as “dirt”) and peels off from the application surface of the skin. Has become. So, on this dirt
It removes dust, residual cosmetics, wastes, etc. adhering to the skin by winding it up.In addition, it is necessary for the skin such as the skin nutritional agent, the skin beautifying agent, the water ingredient, the oily ingredient, and the moisturizer that were originally added. The medicinal properties are taken into the skin during massage.

It is considered that the excrement excreted by the human body is likely to be a mixture of waste products of the skin and external dust, and this will fall off in such a form when water and some oil are added. Similar to the present invention, first, the powder and a certain amount of water are important components of the dirt. For example, when kneading wheat flour during bread making, a phenomenon similar to that of sticking to the skin may be observed, but generally, celluloses, particularly crystalline cellulose, give the best results for making a dart.

[0009] The crystalline cellulose is a partially depolymerized α-cellulose with a mineral acid, and is a fine powder mainly containing the crystals. In Japan, Asahi Kasei Kogyo is marketed under the trade name of "Avicel". In Avicel, there are several types of counts, and when applied to the pack of the present invention, they all produce a dart, although there are considerable differences in properties.

As an experiment, when water is successively added to this powder, it begins to harden and the powder does not fly. If this point is set to Pe and further water is added, it becomes a rice cake-like Pm, and it can be used for a pack even at this position, but if the amount of water is further increased, it becomes a paste-like Pp, which is most suitable for the pack. If more water is added, it will become fluid P
f. In the pack, it is applied on the skin and left for a while,
If the fluidity is too high, it will run off and hinder application. Therefore, the gel type that can be used is Pm to Pf
Between.

However, in another aerosol type,
When ejected, the stock solution must be fluid as it passes through a thin orifice and must not have any coarse particles such as precipitates. Since the can container is shaken and ejected before use, it is desirable that the stock solution is free from sedimentation or two-layer separation even if there is some separation.
In the above experiment, there is a point Ps at which the liquid proceeds in a non-viscous direction when a water component is further added than Pf and exhibits a phenomenon of separation. Therefore, it can be used for the aerosol type stock solution only between Pf and Ps. It becomes fluid when the liquid is diluted, but in the case of the aerosol field, with regard to dripping, it can be solved by using foam or overcoating technology.

[0012]

[Table 1]

Table 1 shows the results of experiments conducted on a commercial product of crystalline cellulose [Avicel]. P
e, Pm, Pp, and Pf are values obtained by quoting the amount of the added water component W in the above state by the amount of crystalline cellulose C. Then, 1 g of mixed Pate in the Pf state is placed on the back of the hand and lightly rubbed with the fingers, the liquid evaporates due to the body temperature and gradually becomes thicker, then suddenly solidifies at a certain point and turns into a dirt. This time was defined as Tt, and the water content of the exfoliated dirt was measured. From the results shown in Table-1, it can be seen that there is a great difference in performance depending on the number of Avicel, indicating that there are various aspects of its application. Regarding the desirable value of Tt, it cannot be said that it depends on the situation of use, but is 1 to 3 minutes appropriate? This adjustment of time is required to be solved by a combination of those counts and means such as addition of alcohol or glycol described later.

Crystalline cellulose makes a good paste, but the situation changes when other powders or oily components are mixed. One of the reasons for incorporating these components is that the fat treated in the paste treated with only crystalline cellulose is removed to make the skin dry, so that the fat and oil component is added. This formulation has a very clear effect. Although it varies depending on the type of oil to be blended, for example, in the case of silicone, even a small amount (2% based on P) gives a smooth feel to the skin. The skin is moisturized by the water content and oily components of the paste, so naturally it is a mixture with a large amount of oil for dry skin, but in the direction where stickiness is disliked, solid oils such as higher alcohols are recommended. Substituted. Another reason for blending oily ingredients is due to the action of removing oily stains adhering to the skin. Since the makeup cosmetics for women, especially for the face, use a large amount of oily components in order to prevent collapse, it is difficult to remove them by simple washing with water, and the pack of the present invention is suitable for performing this complete removal. For that purpose, the oily component in the cosmetic works for the dissolving action of the oily component contained in the pack. When the oily component is a proper amount (about 2 to 15% with respect to P), the construction of the dart is the best, but when the amount is excessive (50% or more with respect to P), the formation of the dart is not good.

Various other powders B are used for removing stains from cosmetics.
The combination of is also effective. It is thought that this component has a scrubbing effect and an effect of wrapping the oily component that has fallen off. Further, when a solid oily component is blended with crystalline cellulose, it is difficult to uniformly disperse it, but it is easier to have a B component, especially in the case of an aerosol, it causes precipitation and separation due to the blending of the oily component. Has the effect of suppressing the tendency to Appropriate amount of various powders B (2-30% of C)
Is the one that most affects the creation of dirt,
If the amount is too much (100% or more with respect to C), the exfoliation property is poor and it will remain on the skin.

In the present invention, when the powder component, the oily component and the water component are mixed, a stable phase which does not take the form of an orgel sol and does not separate is formed, but it is more stable when there is an appropriate amount of the ethanol component E. To do. This is P, A and W
It is thought that the familiarity between them will be improved, and the mixing work will proceed smoothly. Appropriate amount is 4-50% for (P + A)
(4-100% in the undiluted solution for aerosol) E component is also
It has the effect of shortening the dirt formation time Tt, and it is effective for adjusting Tt by this addition. For this purpose, the concentration in the final pack has an effect, so (P + A)
The upper limit value for the gel pack is 50% and for the aerosol type stock solution is 100%. In consideration of the irritating effect of ethanol on the skin, it is safer to keep the ethanol concentration in the final pack product at 10% for body and 5% or less for facial.

The above explanation is confirmed by experiments. Table-2 shows
This is a case where the crystalline cellulose C and another powder B are used in combination. As an example, the powder component P is a mixture of C with [Avicel PH-102] and B with [Kaolin Tsuchiya SP170]. When this combination is used, the formation of dirt is improved from about 2% of kaolin, and the formation of dirt is best with 20% of the mixture, and it worsens again with 50% or more of the mixture, and white powder of kaolin remains on the skin. Therefore, it is concluded that the content of B should be equal to or less than that of C.

[0018]

[Table 2]

Next, with respect to the addition of the oily component A, Table 3 shows an experiment in which isostearyl alcohol was blended as an example. C is [Avicel PH-M15], and B is a mixture P of [Shiraishi Kogyo Kaolin Osmos] at a ratio of 8: 2. When the amount of A added to P is about 2%, the skin feels smooth and smooth. Also, the formation of dirt is better when A is present, and about 5 to 20% of P is the best formation of dirt. However, adding too much delays the build-up time of dirt too much, and there is oil separation, so
50% is accepted as the limit. In the case of silicone, the effect is remarkable with a smaller amount.

[0020]

[Table 3]

Next, regarding ethanol E, this experiment was carried out by [Avicel RC591N] + [Miyoshi Chemical SI
Talc JA68R] = 9: 1 is defined as P, and 100 parts by weight of P is added with 25 parts by weight of the component A [castor oil] to be (P + A). Set this to 1 and E sequentially from 0 to 1.2
20 ml of a paste or a fluid diluent containing (a) 4 and (b) 20 of the water component W was added to the mixture, and the separated state was observed after 5 minutes. On the other hand, Table 4 shows the result of observing the state of formation of the dirt by taking 1 g of the same by the above method. From these results, regarding (a), the formation of dirt was improved even with a small amount of E of 0.02, and 0.2 was the best condition, and 0.
It was not so good at 5 or more. Further, in the separation test of (b), a separation degree of about 0.5 is the smallest, and a phenomenon of worsening again when exceeding 1 is observed.

[0022]

[Table 4]

Now, apart from the other additive components D, the present invention, as described above, has powder component P, oil component A,
The ethanol component E and the water component W are entangled to provide water and oil to the skin to form a dirt removing dirt. In this confirmation experiment, white tanned leather was used, a lipstick was applied to a circle with a diameter of 2 cm, and the pack paste of each composition shown in Table 5 was dropped on this, rubbed with a finger to dirt off, and the residual color of the treated pig skin The line and gloss were measured. The residual color is compared with the color difference ΔE from the raw pig skin using a color difference meter, and the gloss is θ60 using a reflectometer.
Table 5 shows the reflectance λ% at °. From this result, it can be proved that oily stains such as lipstick are removed well and the skin is not roughened.

[0024]

[Table 5]

The experiments shown in Table 6 are examples of several powder components and oil components. Although all of these 6 examples may be in the form of gel packs, it is suggested that the amount of added water W is 2 to 20 times that of P when it is simultaneously used as an undiluted solution for aerosol.
