DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure accumulating (aerosol) massage (body care product), and more particularly to an aqueous concentrated glycerin using a liquefied petroleum gas as a propellant, which can be easily mixed and discharged simply by shaking at the time of use. It relates to a glycerin massage agent.

[0002]

2. Description of the Related Art A concentrated glycerin massage agent is a viscous fluid liquid having the following characteristics. That is, there is a moderate feeling of sliding resistance when performing massage. Therefore, an appropriate physical stimulus can be given to the skin as a massage effect, and the blood flow promoting property of the epidermis can be effectively enhanced.
Glycerin at a concentration of 84.0% or more is hygroscopic, and when the concentration is further increased (from around 90.0% or more), heat is generated simultaneously with the absorption of moisture. The sense of warmth, together with the sense of resistance of the slipper, may result in a more effective sense. Glycerin is very soluble in water, so post-processing is very simple. For example, even if there is no cleaning equipment, it can be easily wiped off with a wet towel (such as a steamed towel).

[0003] Conventionally, glycerin massage agents have been used by adding water to glycerin to dilute it and use it as a warming / softening agent for the skin, and without diluting concentrated glycerin with water.
There is usage as a massage agent. In the case of using as a massage agent, concentrated glycerin (90-98% concentration) is taken from the container into the palm of the hand and applied to the face or the whole body. It is used as a thermal massage agent. In this case, the treatment is often performed while adding various cosmetics (eg, vitamins, proteins, herbal extracts, seaweed powder, etc.) as additives to glycerin, which is both a lubricant and a base.

[0004]

However, the above-mentioned conventional glycerin massage agents have the following problems.
First, a water-soluble drug having an affinity for glycerin must be used as an additive such as the above cosmetics. Next, when considering other general foaming and pressure-accumulation filling (aerosol) products, it is difficult to form an ideal foam (foam) as the blending ratio of glycerin increases in the product components. While considering the balance of the prescription, with a surfactant,
Consideration must be given to forming a good foam corresponding to the glycerin content. This is partly because glycerin acts "antifoaming", albeit less so than alcohol. Even when trying to incorporate a water-soluble substance, it is difficult to mix by shaking due to the above-mentioned "antifoaming" property and very high viscosity. For example, in this case, the only means for mixing a water-soluble substance or a hydrophilic substance (seaweed powder or emulsified material) with concentrated glycerin is stirring or kneading by a heating mechanical force. Alternatively, it is necessary to dilute the concentrated glycerin to 50% or more by adding water, to lower the viscosity, to facilitate shaking, and to mix.

Propellants, which are non-flammable, have high safety to living organisms, and have been used as solvents for many substances, have been practically used because of the problem of environmental pollution or destruction on a global scale. Is impossible. Therefore, the use of combustible gas such as liquefied petroleum gas has become essential as a propellant for aerosol. The liquefied petroleum gas is a C2-C5 hydrocarbon-based mixed gas, corresponding to each product, and adjusting the pressure by changing the mixing ratio of C2 to C5 to obtain an aerosol product. However, since liquefied petroleum gas is a hydrocarbon (oily), it is not chemically mixed or compatible with glycerin. Also, it is difficult to mix physically from the viewpoint of viscosity. An object of the present invention is to provide a novel aerosol glycerin massage agent in consideration of the following points in order to solve the above problems. The problem to be solved is that the performance as a concentrated glycerin massage charge, that is, maintain the viscosity inherent in concentrated glycerin as much as possible and form it so that it can be used as a slippery feeling when performing massage. From the aspect of the massage effect, a massage foam that gives a unique warm feeling at the same time as this concentration. Being able to incorporate desired cosmetic additives (whether aqueous or oily) in order to increase the added value of the product in terms of efficacy. To facilitate the incorporation of concentrated glycerin and liquefied petroleum gas to form a good foam. In addition, this mixing method is to mix easily by shaking a few times immediately before use with shaking at the time of use to form a dense and good foam.

[0006]

In order to satisfy the above-mentioned object, the present invention comprises 84.0 to 93.5% by weight of concentrated glycerin, 0.4 to 1.5% by weight of glycerin fatty acid ester or polyglycerin fatty acid ester. %, Purified water 4.5 to 15.
90-95% by weight of undiluted solution containing 5% by weight and liquefied petroleum gas 1
An aerosol massage agent comprising 0 to 5% by weight. The present invention further provides an aerosol glycerin massage agent containing the above-mentioned stock solution and an additive for improving cosmetic effects. Glycerin used in the present invention has a concentration of 90-9.
8% by weight commercially available concentrated glycerin. Although this concentrated glycerin is a viscous fluid liquid, the present invention makes it possible to apply glycerin in the form of a foam by forming an aerosol while maintaining the hygroscopic action peculiar to glycerin and accompanying exothermicity. Is easy and simple, and a more functional massage agent can be obtained.

[0007] Therefore, in the present invention, it is necessary to mix the above concentrated glycerin with liquefied petroleum gas, but oily liquefied petroleum gas is not compatible with aqueous concentrated glycerin. Observation when both are stored under pressure in a pressure-resistant glass bottle shows that concentrated glycerin has a high viscosity and therefore has poor rocking properties, whereas liquefied petroleum gas has a very low viscosity.
This is shaken vigorously, and even if it is temporarily mixed, it is instantaneously separated into its original state. In other words, the lower layer is concentrated glycerin, and the upper layer is liquefied petroleum gas. In order to eliminate this state, the presence of a surfactant is essential. The conditions for selecting the surfactant are such that glycerin has an affinity for solubilized petroleum gas C _{2 to} C ₅ , so that as little as possible, concentrated glycerin and liquefied petroleum gas become compatible with each other. Foaming which is one of the conditions
And foam retention (keeps bubbles for a long time so that they do not collapse)
It must be able to satisfy all of these things.

The present inventors have selected surfactants which are dissolved in concentrated glycerin and have a high affinity for liquefied petroleum gas, and the search and examination are repeated, and glycerin fatty acid esters are generally appropriate and good. It turned out to be. Among these glycerin fatty acid esters, there are polyglycerin fatty acid esters from monoglycerin fatty acid esters and polyfatty acid esters in which several fatty acids are bonded to polyglycerin. The glycerin fatty acid esters were further examined, and as a result, solubility in concentrated glycerin, viscosity at room temperature after dissolution, affinity with water and liquefied petroleum gas, and foaming property (foam formation after commercialization)
And to explore and comprehensive evaluation of foam retention, etc. As a result of extensive research, mono-fatty acid esters of C ₁₂ to decaglycerol to C ₁₈ are particularly found to be suitable. C ₁₂ is lauric acid, and this decaglyceryl monolaurate has a soft foaming property, and C ₁₈ stearic acid, that is, decaglyceryl monostearate, forms a considerably harder foam.
C ₁₄ (myristic acid) and C ₁₆ (palmitic acid) form intermediate hardness foams of C ₁₂ and C ₁₈ esters, respectively (the C ₁₈ foam is the hardest of these).
The rate of addition of the glycerin fatty acid ester to the concentrated glycerin was 84.0 to 84.0 in concentrated glycerin (based on 98%).
93.5% of glycerin fatty acid ester 0.4 to 1.0.
A range of 5% is preferred. If the glycerin fatty acid ester is less than 0.4%, the effect as a surfactant will be lost, and if it is more than 1.5%, glycerin will be diluted, which will affect the massage effect such as viscosity and warmth. Neither is preferred.

Next, in the present invention, in order to form glycerin into a foam (foam), the presence of water together with the surfactant is weight. And foam is easy to be formed, so that a water content is large. However, in this case, the amount of the compound must be extremely reduced, and the compounded amount must be as small as possible. That is, concentrated glycerin (98% basis) 84.0
A ratio of 4.5 to 15.5% of purified water to 93.5% is preferable. If the amount of water is less than 4.5%, the formation of the foam is insufficient, which is not preferable. If the amount of water is more than 15.5%, glycerin is diluted like the surfactant, which is not preferable. The composition of the stock solution that is the basis of the present invention described above is 84.0 to 93.5% concentrated glycerin, 0.4 to 1.5% glycerin fatty acid ester, and 4.5 to 15.5% purified water. The stock solution having the above composition is easily mixed and dissolved with liquefied petroleum gas to form a dense and easy-to-handle foam, which can be an excellent skin massage material.

The pressure range of the liquefied petroleum gas mixed with the undiluted solution is usually 4.0 kg / cm ² (the composition is C ₂ : 0.2).

The concentrated glycerin massage agent of the present invention, as long as the foam formation is not impaired, ingredients for enhancing cosmetic effects, fragrances, preservatives, ultraviolet absorbers, pigments, vitamins,
Proteins, extracts and the like can be incorporated in an amount of up to about 0.5% regardless of whether they are oily or aqueous.

Next, a method for preparing the aerosol glycerin massage agent of the present invention will be described. First, a predetermined amount of glycerin fatty acid ester is added to a predetermined amount of concentrated glycerin, and if necessary, a small amount of a preservative such as paraben is added, and the mixture is heated and stirred at about 80 ° C. in a water bath or high-pressure steam to dissolve. After complete dissolution, the mixture is immediately cooled to about 50 ° C., and a predetermined amount of purified water, which has been separately heated to about 50 ° C., is mixed with stirring. After mixing, the mixture is cooled to room temperature (20 to 25 ° C) to obtain a stock solution. If necessary, an aerosol massage agent can be prepared by adding a cosmetic effect enhancer to the above-mentioned undiluted solution as required and accumulating and filling a predetermined amount with a predetermined amount of liquefied petroleum gas.

DETAILED DESCRIPTION OF THE INVENTION Next, the basic formula of the aerosol glycerin massage agent of the present invention will be described in more detail and concretely with reference to examples. The present invention is not limited to these embodiments. The content is% by weight
It is. [Example 1] Concentrated glycerin (concentration 98.0%) 89.9 (% by weight) Decaglycerol monomyristate 1.0 Paraben 0.1 Purified water 9.0 Preparation method: (A) Concentrated glycerin added to decaglyceryl mono The myristate (surfactant) and paraben are weighed together in a dissolution tank, and heated and stirred at 80 ° C. with aqueous or high-pressure steam to dissolve. (B) The purified water is weighed in another dissolving tank and heated to 50 ° C. (in this case, a method is used in which water evaporation is prevented as much as possible). (C) Immediately after A is completely dissolved, the mixture is cooled with water and cooled to 50 ° C., and B is added and mixed while stirring is continued. After mixing, water cooling is started again and cooled to room temperature (25 ° C to 20 ° C) to obtain a stock solution. By mixing decaglyceryl monomyristate and purified water, the viscosity of concentrated glycerin is greatly reduced, and the miscibility of this stock solution and liquefied petroleum gas by shaking operation is improved, resulting in an extremely good state. 95% by weight of the stock solution thus prepared is placed in a pressure-accumulating filling container, and a discharge valve is attached and sealed, and 5% by weight of liquefied petroleum gas is filled. The pressure of the liquefied petroleum gas was 5.8%).

The stock solution was placed in a pressure-accumulating filling container, and one glass ball or stainless steel ball having a diameter of 7.0 mm was sealed before the discharge valve was attached. By enclosing the spheres in this way, the mixing by shaking is further improved, and the quality of the foam can be improved. This is because the ball assists stirring and mixing by shaking. Regarding the pressure range and filling amount of the liquefied petroleum gas used, the pressure is 4.

_{C 4: 12.0%, nC 4} : 52.0%, C 5: 0.1%) over 5.0 Kg / cm ² loadings: preferably used in the range of 5 to 10 wt%.

In the case of using this liquefied petroleum gas, the selection and determination of the pressure and the filling amount are determined in the case where some cosmetic-promoting additives are added in addition to the above-mentioned standard formulation (mostly, However, it is selected as needed while considering the miscibility (relationship) with liquefied petroleum gas. This is because the mixed state is directly related to the foam quality when discharged to the outside, and this is one of the quality evaluations as an aerosol product. That is, depending on whether the substance to be added is oil-based (eg, vitamin E) or water-based (eg, hydrolyzed protein), the state of the foam varies considerably. Determine the gas pressure and filling volume that are considered to be most appropriate while determining the nature of the stock solution. The glycerin massage agent thus prepared is shaken several times before use, and the valve is opened (by pressing a button) to discharge the contents, and concentrated glycerin discharged in the form of foam (foam powder) is used. Massage while squashing and stretching to the skin. In this case, the container used and the discharge button (spout) may be of an upright type or an inverted type.

[Examples 2 to 12] Based on the formulation shown in Table 1, vitamins, proteins, and other drugs having moisturizing, protecting, and nutritional purposes were blended, and glycerin was observed while observing the appearance of each base. And the balance of purified water was adjusted to obtain a product according to Example 1.

EFFECTS OF THE INVENTION The massage agent of the present invention has a firm foam (foam powder), and, like concentrated glycerin, has a feeling of resistance to massage and a feeling of warmth. Unlike liquid concentrated glycerin, it can be used easily and comfortably without the need to worry about flowing (dripping) during handling. Therefore, not only when the place to be massaged is on a horizontal surface (upward surface), but also vertically (the face when the person is sitting, or the elbow or arm when the back and arms are stretched straight forward) In such cases, the glycerin massage agent can be conveniently used. In other words, the discharged foam can be once taken in the palm of the hand, and massaged while crushing the foam against the intended location. After the massage is finished, it can be washed off with water or lukewarm water (it can be easily washed off) or it can be easily wiped off with a wet towel such as a steamed towel.
