Description

  The present invention relates to a massage fee. More particularly, the present invention relates to a massage material that is preferably used for massage on the shoulder and / or back in order to prevent and / or improve facial wrinkles.

  The act of massage promotes blood circulation of the skin, promotes the metabolism of the skin and improves the state of the skin, and acts directly or indirectly on the muscles / muscles / joints to improve the blood circulation state. It has been suggested for a long time that there are various effects such as relaxing and comforting the mind and body, for example, as well as physiological effects such as sports massage aimed at promoting recovery from fatigue. However, the effect of massage on the human body is extremely mild, and the human body itself changes slightly, so it is difficult to present its short-term or sustained effect, and it can actually exhibit useful effects on the living body. A massage fee was desired.

  For this reason, it is recognized that the development of a technique for a non-invasive biological index capable of measuring and evaluating such an effective action is an indispensable and important issue when developing a massage material. As such an effective index, for example, Patent Document 1 discloses an immunoglobulin concentration in saliva, Patent Document 2 describes an autonomic nervous system balance such as skin surface temperature, Patent Document 3 discloses an adrenal cortex hormone concentration in saliva, Patent Document 4 Is the alpha wave of the electroencephalogram, Patent Document 5 is the degree of change in the three-dimensional shape of the target part, Patent Document 6 is the oxygen saturation of blood hemoglobin, and Patent Document 7 is a composite index such as blood oxygen concentration and muscle hardness. The evaluation method to perform is disclosed, and an appropriate index is selected according to the purpose of the treatment, and it is used to develop a more effective massage fee. On the other hand, myoelectric potential (electromyogram) is a numerical value indicating changes in muscle tension, and this measurement method has already been established. Such a numerical value is used as an index for diagnosing muscular dystrophy and screening for potential-dependent calcium channel agonists (see, for example, Patent Document 8). In addition, many studies and presentations have been made as indicators of changes in muscle tension, and applications in the medical and sports fields are thriving. Is a situation rarely done.

  On the other hand, the massage method is inextricably linked with the massage fee, and in order to provide a higher effect on the mind and body, the massage treatment technology and the technical development of the target part are being studied, including the examination of massage devices and tools. Has been done. For example, Patent Document 9 discloses a method for enhancing relaxation by performing a treatment synchronized with the respiratory rhythm of a non-practitioner, Patent Document 10 discloses a method for improving symptoms by performing a treatment on acupuncture points corresponding to the psychosomatic symptoms of a non-practitioner, 11 discloses a method for enhancing the cosmetic effect by performing treatment in the direction of dermal fibers and arteriovenous blood flow based on the skin structure, and it has been suggested that the use of psychophysiological functions is important. From these facts, it is clear that a technique for accurately evaluating the massage method is important.

  For many women, skin morphological changes represented by wrinkles and skin firmness, which are important as beauty elements, are particularly serious problems because they have a very negative effect on appearance. For this reason, various techniques for preventing wrinkles, such as surgical methods, cosmetics, tools, foods, and the like have been disclosed, and research for the formation and suppression of wrinkles has been conducted. For example, the cosmetic treatment method using the neurotoxin of Clostridium botulinum in Patent Document 12 and the disclosure of a cosmetic for relaxing muscles for suppressing expression wrinkles using an electromyogram in Patent Document 13, the wrinkle of Non-Patent Document 1 A review of classification, generation mechanism, and evaluation technology is presented. There has been a strong demand for a massage fee that is more convenient, safer, and more effective than wrinkles. However, although the wrinkle-suppressing effect by the massage fee is expected, the wrinkle-reducing effect based on the improvement of the body fluid circulation induced by the moisturizing effect and the blood circulation promoting effect of the cosmetic and the massage material itself is still limited. It was. In other words, it is not known that wrinkles are related to changes in physiological functions caused by the treatment of the trunk, and in particular, it improves the tension of the muscles of the trunk, which exists remotely from the formation part of the wrinkles It has never been known until now that massage can relieve facial muscle tension and improve facial wrinkles.

These oils and fats that are liquid at 1 atm. 25 ° C. must be contained in a total amount of 50% by weight or more, more preferably 60% by weight or more, based on the total amount of the cosmetic. By containing these oils and fats in an amount of 50% by weight or more, it is possible to reduce the change in the rubbing strength of the massage during the massage treatment, and to realize comfort and relaxation of muscle tone more effectively. Here, the trunk in the present invention means a general term for the body part excluding the hands, feet, and head, and the trunk to be massaged is preferably the back of the trunk, the back, shoulder or neck. A side surface and a back surface can be preferably exemplified. As the massage to be performed on the trunk, a technique as shown in FIG. 1 for performing light rubbing, compression, finger pressure, etc. on the back, shoulders and neck is preferable.

  The cosmetic dosage form of the present invention may be a single-phase system such as oil, a water-in-oil, oil-in-water or multi-phase emulsification system, or a multiphase system such as an oil gel. It may be. A more preferable form is a single-phase system or a multi-phase system such as an oil gel in which there is no change in the friction coefficient due to a change in the emulsified layer.

  In the cosmetics of the present invention, in addition to the essential components, optional components usually used in cosmetics can be contained as long as the effects of the present invention are not impaired. Such optional components include, for example, hydrocarbons such as microcrystalline wax and solid paraffin that are not liquid at 1 atm 25 ° C., high polymerization dimethicone, and crosslinked methylpolysiloxane that is not liquid at 1 at 25 ° C. , Carnauba wax, molasses, beeswax, gay wax, etc. 1 atm of non-liquid esters such as stearic acid, lauric acid, myristic acid, palmitic acid, isostearic acid, isopalmitic acid, behenic acid, etc. Fatty acids that are not liquid at 25 ° C., higher alcohols such as behenyl alcohol, cetanol and the like that are not liquid at 25 ° C., triglycerides such as hydrogenated coconut oil, glyceryl tristearate, 1,3-butanediol, glycerin, di- Glycerin, dipropylene glycol, poly Polyhydric alcohols such as tylene glycol, 1,2-pentanediol, 1,2-hexylene glycol, isoprene glycol, sorbitan sesquioleate, sorbitan monooleate, sorbitan trioleate, sorbitan sesquistearate, sorbitan monostearate, polyoxy Nonionic surfactants such as ethylene sorbitan monooleate, polyoxyethylene sorbitan monostearate, polyoxyethylene stearate, polyoxyethylene oleate, polyoxyethylene glyceryl fatty acid ester, polyoxyethylene alkyl ether, polyoxyethylene hydrogenated castor oil , Anionic surfactants such as sodium lauryl stearate, polyoxyethylene alkyl sulfate, sulfosuccinate ester salt, quaternary alkyl ammonium Cationic surfactants such as salt, amphoteric surfactants such as alkylbetaine, organic powders such as crystalline cellulose, cross-linked methylpolysiloxane, polyethylene powder, acrylic resin powder, talc, mica, sericite, Magnesium carbonate, calcium carbonate, titanium dioxide, iron oxide, bitumen, ultramarine, titanium mica, titanium sericite, powders that may be surface treated such as silica, thickeners such as xanthan gum and hydroxypropyl cellulose, retinol, Vitamins such as retinoic acid, tocopherol, riboflavin, pyridoxine, ascorbic acid, ascorbic acid phosphate ester, terpenes such as glycyrrhetinic acid, glycyrrhetin, ursolic acid, oleanolic acid, estradiol, ethinylestradiol, estriol, etc. Preferred examples include steroids and other active ingredients, preservatives such as phenoxyethanol, parabens, hibitene gluconate, and benzalkonium chloride, and ultraviolet absorbers such as dimethylaminobenzoates, cinnamic esters, and benzophenones. . Here, “unless the effect of the present invention is impaired” means that a massage treatment can be performed with a uniform coefficient of friction, and specific properties include a temperature around body temperature, specifically, 35 ° C. In this regard, it can be preferably exemplified that the properties of the cosmetic are in a liquid or semi-solid state.

  The cosmetic of the present invention is used at the time of massage treatment, and when used for massaging the trunk of the back, shoulders and neck, the cosmetic body does not phase-shift in the trunk, Facial muscle tone can be further relaxed. At that time, when using a towel, sponge, or the like, it is more preferable that the change in the coefficient of friction is small in order to relieve muscle tension. When the friction with the skin is large, it not only increases discomfort and tension, but also causes damage to the skin, such as detachment of the skin stratum corneum cells, and the friction measurement of living skin is an important factor. . As a method for measuring such friction with the skin, for example, in consideration of the flexibility of living skin, the sensory motion of measuring the feeling of slipping by reciprocating the skin surface with the fingertip is simulated, and a curved fingertip shape is simulated. Various devices have been developed and put to practical use, such as a device that reciprocates a pickup having a metal plate at its tip and measures the frictional force at that time (see Non-Patent Document 3). When the “skin slip resistance measuring device” described in Non-Patent Documents 2 and 3 is used as such a device, the slip resistance value of the inner part of the forearm is about 37 gr (the friction coefficient is 0.93 with respect to a contact load of 40 gr. ), But by applying massage oil or the like, the slip resistance value can be reduced to 16 to 28 gr (friction coefficient is 0.40 to 0.70).

Here, muscle tension refers to external factors such as mental stress, physical abuse, visceral disease, poor posture, or muscular tension that persists due to dietary disturbances or lack of sleep. With lymphatic flow worsening and accumulation of waste products in muscles, blood, and lymph, such conditions can further stimulate the nervous system, promote muscle tension, stiff necks, shoulders, headaches, etc. It is thought to cause physical modulation. A non-invasive method is desirable as a method for objectively measuring muscle tension, which is the degree of muscle tension, and generally a measurement method corresponding to a body part or symptom is used. As such a measuring method, for example, for the face and trunk part, surface myoelectric potential measurement representing muscle muscle tension information of many muscle fibers and muscles can be exemplified. On the other hand, the state of trunk muscle such as stiff shoulders Can be exemplified by a muscle hardness meter that measures the muscle hardness. Examples of the surface electromyograph include a myoelectric potential measuring instrument manufactured by Harada Hyper Precision Co., Ltd. and a digital electroencephalograph alliance work manufactured by Japan GE Marquette Medical System Co., Ltd. To obtain muscle tension by the surface myoelectric method, attach an electrode to the forehead, etc., and integrate the electromyogram using the electromyogram at rest with the eyes closed while sitting and with eyebrows raised The resting muscle tone of the frontal muscle is calculated using the electromyogram integral value (μV). “Front muscle strength at rest” = “electromyogram integral value (μV) at rest for 5 seconds” / “electromyogram integral value (μV) at 5 seconds in eyebrow up state”. Individual differences are eliminated by dividing the resting muscle tone by the electromyogram integral value in the state of eyebrow pulling up, and it is considered that the daily muscle tone specific to the subject is reflected.

  The muscle hardness can be measured by a muscle hardness meter, and examples thereof include a biological tissue hardness meter PEK-1 manufactured by Imoto Seisakusho Co., Ltd. or Henry Japan Co., Ltd., and a tissue hardness meter Newton manufactured by Triall Co., Ltd. In order to measure the muscle hardness of the stiff shoulder using the muscle hardness meter PEK-1, it is preferable in terms of reproducibility to select the position of the stiff shoulder based on the acupuncture points (acupoints) and the cervical spine which are anatomical features. The average value of the obtained muscle hardness meter values can be defined as the muscle tone of the trunk.

To evaluate the massage fee of the present invention, in the same massage treatment, only the intervening massage fee is changed, the massage treatment is performed, the degree of relaxation of muscle tone is obtained, and the degree of relaxation of the massage fee is compared. Evaluation, more specifically, a massage fee for massage performed on the trunk for improving or preventing facial wrinkles can be evaluated. At that time, in order to ensure the probability of evaluation, it is preferable to perform evaluation using a plurality of subjects and perform statistical analysis such as a significant difference test. At this time, the number of subjects may be a number enough to withstand statistical processing, specifically at least 10 and more preferably 50 or more. Such an evaluation is performed according to the following procedure.
(1) A panelist is selected and basic physiological functions such as resting muscle tone (electromyogram) are measured in advance.
(2) Using the basic physiological function as an index, grouping is performed so that the distribution of the basic physiological function is not biased into the same number of groups as the number of types of massage materials to be evaluated. At this time, the number of examples per group may be a number enough to withstand statistical processing, as in the evaluation of the massage method, specifically at least 10 examples, more preferably 50 examples or more.
(3) Before the operation, measure the resting muscle tone (electromyogram).
(4) Change the massage fee for each group so that there is no difference in the proficiency level of the practitioner, massage the trunk without changing the massage treatment, and then regain resting muscle tone (electromyogram) ).
(5) The measured values of (3) and (4) are compared, and the degree of average relaxation of resting muscle tone for each group by treatment is obtained. This is compared statistically, and the higher the degree of relaxation of resting muscle tone, the better the massage fee is determined by wrinkle improvement.

  The evaluation of prevention and / or improvement of facial wrinkles can be objectively measured by collecting replicas from the forehead portion or the like in a resting state and then performing replica image analysis of the wrinkles on the replicas. Examples of the replica agent include Asahi Biomed's reflective silicon ASB-01-WW. Wrinkle replica image analysis is a wrinkle image analysis parameter according to the guidelines of the Japan Cosmetic Industry Association (http://www.jcia.org/) using general image analysis software, and the area ratio (%) The total wrinkle average depth (mm), the maximum wrinkle average depth (mm), and the maximum wrinkle maximum depth (mm) can be obtained. Examples of such image analysis software include WinROOF (registered trademark) of Mitani Shoji Co., Ltd. and Asahi Biomed's reflection replica analysis system ASA-03-R.

  Hereinafter, the present invention will be described in more detail with reference to examples, but it goes without saying that the present invention is not limited to such examples.

  It was confirmed that the facial wrinkle according to the present invention and the frontal muscle tone degree of the facial part are related. Replicas were collected from the center of the forehead using 85 Asahi Biomed's reflective silicones, 20 minutes after face washing, for 85 healthy female subjects (21-57 years old) selected at random. In accordance with the guidelines of the Japan Cosmetic Industry Association, the collected replicas are image analysis software using the image analysis software area ratio (%), total wrinkle average depth (mm), maximum wrinkle average depth (mm), and The maximum wrinkle maximum depth (mm) was determined.

  After collecting replicas, in the shield room, after mounting the plate electrodes on the forehead, etc., at a pair of left and right at a distance of 1 cm in the longitudinal direction, 2 when resting with the eyes closed while sitting and with tension while raising the eyebrows The myoelectric potential was measured under the conditions, and the resting muscle tone of the frontal muscle was calculated from the electromyogram integral value (μV).

  Correlation analysis was performed on the relationship between the resting muscle tone of the frontal muscle obtained from the myoelectric potential measurement of the forehead and the wrinkle image analysis parameters obtained from the replica of the forehead, and the results are shown in Table 1 (wrinkle score). Is a Spearman correlation coefficient, and the image analysis parameter is a Pearson correlation coefficient). From Table 1, there is a significant and high positive correlation between the muscle tone at rest and the wrinkle score and wrinkle image analysis parameters, which are indices of wrinkles. It can be seen that people with high levels of tension have more wrinkles. That is, it can be seen that facial muscle tone and surface myoelectric potential are effective as wrinkle indicators, and that wrinkle can be prevented or improved by taking measures to reduce frontal muscle tone at rest.

  It was also confirmed that facial wrinkles according to the present invention and trunk muscle tone were related. In the subject of Example 1, after using the VAS form (Visual Analogue Scale, see FIG. 2), which is a questionnaire to examine the degree of awareness of shoulder stiffness, the current shoulder stiffness (VAS value, unit cm) is entered, The muscle hardness at the midpoint of the shoulder ridge and the seventh cervical vertebrae where stiff shoulders easily occur was measured using a biological tissue hardness meter PEK-1.

  The relationship between muscle hardness at the shoulder where shoulder stiffness is likely to occur, wrinkle image analysis parameters, VAS value (cm) as the degree of awareness of shoulder stiffness, and frontal muscle resting muscle tone obtained from myoelectric potential measurement at the forehead Correlation analysis was performed on the results, and the results are shown in Table 2 (Pearson's correlation coefficient). From Table 2, a significant and high positive correlation is found between shoulder muscle hardness, wrinkle image analysis parameters, VAS value, which is an index of shoulder stiffness awareness, and frontal muscle resting muscle tone. It can be seen that a person with high muscle hardness in the shoulder has a lot of wrinkles and is apt to be stiff, and has a high degree of muscle tension at rest of the frontal muscle. That is, it can be seen that muscle hardness is effective as an index for stiff shoulders, and wrinkles can be prevented or improved by taking measures to reduce muscle hardness, that is, shoulder stiffness.

Using the cosmetics 1 (oil type) for massage shown below according to the present invention, the effect on the wrinkles of the face and the muscle tone of the trunk and the face by the massage treatment to the trunk was examined. Using the same measurement means as in Examples 1 and 2, eleven female subjects (41 to 53 years old) who are suffering from stiff shoulders, face-washing for 20 minutes, collecting replicas from the forehead part, surface of the forehead part After performing myoelectric potential measurement and shoulder muscle hardness measurement, use the massage cosmetic 1 to perform massage treatment on the back, shoulder and neck, such as light rubbing, compression and acupressure, as shown in FIG. Esthetician went for 20 minutes. After the treatment, surface myoelectric potential and muscle hardness were measured as before the treatment. Massage to the trunk was performed twice a week at the same time zone, and after one month, the measurement was performed before and after the treatment in the same manner as the first time.
(Cosmetics 1)

(Production method) Stir and solubilize at room temperature.

  Table 3 shows the results of analysis of the measured replica, surface myoelectric potential, and muscle hardness. From Table 3, after massage treatment, resting muscle tone (relaxation 77%) and muscle hardness significantly decreased (P <0.01), and after 1 month resting muscle tone (relaxation 70%) ) And muscle hardness, the wrinkle image analysis parameters also decreased significantly (P <0.01). From this, it can be seen that the cosmetic 1 for massage applied to the trunk for preventing and / or improving facial wrinkles is effective.

  Using the same technique as in Example 1, the effect on the frontal muscle tone of the facial part was examined with respect to the difference in effect due to the type of cosmetic for massage when the same massage treatment was performed on the trunk. . Forty-eight female subjects (35-54 years old) suffering from stiff shoulders, muscle tension, age, and wrinkle level were measured in advance and divided into 4 groups so that these indices would not be biased. After measuring the surface myoelectric potential of the forehead, the massage treatment for the back, shoulders and neck, such as light rubbing, compression and acupressure, as shown in FIG. For 20 minutes by one esthetician. After the treatment, the surface myoelectric potential was measured in the same manner as before the treatment, and the resting muscle tone before and after the treatment was obtained. As cosmetics for massage, cosmetics 1 (oil type), cosmetics 2 (oil gel type, soft paste at 35 ° C.) and cosmetics 3 (emulsification type) of the present invention, and cosmetic 1 as a comparative example Four types of cosmetics 4 (oil gel type, solid at 35 ° C.) obtained by substituting squalane and heavy liquid isoparaffin with microcrystalline wax (a component not liquid at 1 atm 25 ° C.) were used. In implementation, considering the fatigue and habituation of estheticians, the number of treatment subjects in the morning treatment was 6 per day, and the order of use of cosmetics was random for each day.

  Table 4 shows the results of a t-test (paired-t test) before and after treatment for the effect on the degree of frontal muscle tension (relaxation) by the type of massage cosmetics applied to the trunk. From Table 4, the resting muscle tone level (relaxation level 77-81%) decreases significantly (p <0.01) in the cosmetics 1 to 3 of the present invention, but the comparative cosmetic 4 that is not the present invention rests. No decrease in muscle tone (relaxation 94%) was observed, confirming the effect of the cosmetic of the present invention.

  The subjects in Example 4 and cosmetics 1 for massage (oil type), cosmetics 2 (oil gel type, soft paste at 35 ° C.), cosmetics 3 (emulsification type), and comparative examples of cosmetic 1 For 4 types of cosmetics 4 (oil gel type, solid at 35 ° C), in which squalane and heavy liquid isoparaffin are replaced with microcrystalline wax (component that is not liquid at 1 atm 25 ° C), whether or not towels are used is a massage material The effect on the friction coefficient between the skin and the skin was confirmed. When the above-mentioned “skin slip resistance measuring device” is used, the slip resistance value (coefficient of friction) is measured when massage oil is applied to the inner part of the forearm under the condition of a contact load of 40 gr, and then the contact is covered with a towel The sliding resistance value was measured assuming that a towel was used, and Table 5 shows the change in the coefficient of friction between the massage material and the skin due to the use of the towel. From Table 5, the cosmetics 1 to 3 have small changes in the friction coefficient, but in the cosmetic 4, the friction coefficient greatly increases when the towel is used, and it is difficult to perform massage treatment and relieve muscle tension. From this, it can be seen that it is preferable that the coefficient of friction is small due to the use of the towel.

  According to the present invention, it is possible to provide a massage material capable of appropriately expressing the effect for preventing or improving facial wrinkles. As a result, skin troubles such as wrinkles can be reduced or eliminated, and more customers can be satisfied.
