Description

[Technical field]

[0001] The present invention relates to cosmetic macadamia nut oil and a method for producing the same, and more particularly to cosmetic macadamia nut oil activated to treat various skin problems and a method for producing the same. [Background technology]

[0002] It has been generally known that macadamia nut oil is used as a cosmetic oil for massage, skin care, etc. (see, for example, Patent Documents 1 and 2). Macadamia nut oil is also known as vanishing oil, and has high permeability to the skin and is familiar to the skin. Therefore, it can be used on various parts of the body, from the toes to the hair. In addition, since it contains a lot of palmitoleic acid, which is similar to human sebum (especially that of young people), it is ideal for use on aging skin and dry skin, and is expected to improve elasticity, regenerate, and repair the skin. In addition, since it contains vitamins, it helps rejuvenate the skin. Furthermore, since it is resistant to oxidation and has good storage properties, it is an oil that is easy to handle even in ordinary households. [Prior art documents] [Patent documents]

[0007] According to the method for producing cosmetic macadamia nut oil of the present invention, the method includes a washing step of washing quartz schist with hot water or warm water, a contact step of putting the washed quartz schist into a container, pouring macadamia nut oil on the quartz schist to bring the quartz schist and the macadamia nut oil into contact with each other, and a separation step of separating the macadamia nut oil that has been in contact with the quartz schist from the quartz schist that has been in contact with the macadamia nut oil. By contacting the quartz schist in this way, cosmetic macadamia nut oil that has been activated to deal with various skin troubles can be obtained. In particular, cosmetic macadamia nut oil that has extremely high skin permeability, good skin compatibility, and little stickiness can be obtained. In addition, when the contact step is carried out by leaving the mixture to stand, no complicated stirring process is required, and the macadamia oil can be effectively activated by contact with the quartz schist. In addition, when the contact step is carried out at a temperature between 15 and 25°C, the macadamia nut oil can be effectively activated by contact with the quartz schist at room temperature. In addition, when the contact step is carried out for 26 to 46 hours, the macadamia nut oil can be effectively activated by contact with the quartz schist. Furthermore, when the washing step involves washing a plurality of quartz schists having a maximum width of 5 to 30 mm with hot water, the quartz schists can be effectively washed, and the macadamia nut oil can be effectively activated by contact with a large number of relatively small quartz schists. Furthermore, when the separation step is carried out by filtering the macadamia nut oil through a filter, impurities can be removed and the macadamia nut oil can be effectively separated. According to the cosmetic macadamia nut oil of the present invention, since it is produced by the above-mentioned method for producing cosmetic macadamia nut oil, it is activated so as to be able to deal with various skin troubles. In particular, it has extremely high skin permeability, good skin affinity, and little sticky feeling. [Brief description of the drawings]

[0008] The present invention will be further described in the following detailed description by way of non-limiting examples of exemplary embodiments according to the invention and with reference to the several drawings mentioned, in which like reference numerals refer to like parts throughout the several views of the drawings. [Figure 1] FIG. 2 is an explanatory diagram for explaining a method for producing cosmetic macadamia nut oil according to an embodiment, in which (a) shows a washing process, (b) shows a contact process, and (c) shows a separation process. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] The matters shown herein are illustrative and are intended to exemplify the embodiments of the present invention, and are described for the purpose of providing what is believed to be the most effective and easily understandable explanation of the principles and conceptual features of the present invention. In this respect, it is not intended to show structural details of the present invention beyond the extent necessary for a fundamental understanding of the present invention, and the description in conjunction with the drawings will make it clear to those skilled in the art how some forms of the present invention can be actually embodied.

[0010] <Manufacturing method of cosmetic macadamia nut oil> The manufacturing method for cosmetic macadamia nut oil in this embodiment includes, for example, a washing process (see FIG. 1(a)) of washing quartz schist q with hot water h or warm water h, as shown in FIG. 1, a contacting process (see FIG. 1(b)) of placing the washed quartz schist q in a container 2 and pouring macadamia nut oil m on the quartz schist q to bring the quartz schist q into contact with the macadamia nut oil m, and a separation process (see FIG. 1(c)) of separating the macadamia nut oil m that has come into contact with the quartz schist q from the quartz schist q that has come into contact with the macadamia nut oil m.

[0011] The form of the above-mentioned "washing step" is not particularly limited. In the washing step, for example, as shown in FIG. 1(a), a plurality of quartz schists q having a maximum width of 5 to 30 mm can be washed with hot water h or warm water h. This maximum width refers to the width of the quartz schist q at which the distance between two parallel lines is maximum when the projection image of one quartz schist q on a plane is sandwiched between the two parallel lines.

[0012] Quartz schist q is composed mainly of silica (SiO2) and alumina (AL2O3). Quartz schist q also has a porous structure that is excellent at absorbing harmful substances, and contains many trace elements (minerals). Quartz schist q also emits strong far-infrared rays under various temperature conditions compared to bakuhan stone, tourmaline, artificial ceramics, etc. It has also been demonstrated that it generates a large amount of negative ions in addition to far-infrared rays. It is believed that the far-infrared rays and / or negative ions emitted by this quartz schist q activate the macadamia nut oil m that comes into contact with the quartz schist q (especially modifying it so that it is more penetrable into the skin).

[0013] The form of the above-mentioned "contact step" is not particularly limited. As the container 2 used in the contact step, for example, one having a capacity of 50 to 150 liters (preferably 80 to 120 liters) can be adopted. In this container 2, for example, quartz schist q weighing 5 to 15 kg (preferably 8 to 12 kg) can be placed. Furthermore, in the container 2, for example, macadamia nut oil m can be placed in an amount of 70% or more (preferably 80% or more) of the capacity.

[0014] The contact step can be carried out, for example, by allowing the quartz schist q and the macadamia nut oil m to stand in the container 2. The contact step can be carried out, for example, at room temperature (i.e., 15 to 25° C.) around the container 2. The contact step can be carried out, for example, for 26 to 46 hours (preferably 30 to 40 hours).

[0015] The form of the above-mentioned "separation step" is not particularly limited. The separation step can be carried out, for example, by filtering the macadamia nut oil m with a filter 5.

[0016] <Macadamia nut oil for cosmetics> The cosmetic macadamia nut oil according to this embodiment is cosmetic macadamia nut oil m produced by the cosmetic macadamia nut oil producing method according to the above embodiment. Applications of cosmetic macadamia nut oil m include, for example, skin care, massage, hair care, cleansing, etc.

[0017] In addition, the cosmetic macadamia nut oil of the present invention has a very high skin permeability, good skin compatibility, and a feeling of little stickiness. However, since this feeling is an index that depends on human subjectivity, it is difficult to quantify. In addition, the cosmetic macadamia nut oil of the present invention is thought to be activated by far-infrared rays and / or minus-in emitted by quartz schist, but it is impossible to analyze and identify the changes in the components constituting the cosmetic macadamia nut oil by contact with quartz schist even with current analytical equipment, and it is not possible to know the correlation with the effect of the above-mentioned specific feeling. Therefore, it is not practical, impossible or impractical to directly identify the cosmetic macadamia nut oil of the present invention by its structure or properties, such as by identifying the components and their structures that contribute to the effects of the present invention.

[0018] The reference numerals of the components described in the above embodiment indicate the corresponding relationship with the specific components described in the examples described later. EXAMPLES

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The method for producing cosmetic macadamia nut oil according to this embodiment includes a washing step, a contact step, and a separation step described below.

[0021] The washing step is a step of washing the quartz schist q with hot water h (or warm water h) as shown in Fig. 1(a). In this washing step, a number of quartz schists q with a maximum width of 10 to 20 mm are washed with hot water h. More specifically, the quartz schist q is placed in a container 1 and hot water h is poured onto the quartz schist q to wash the quartz schist q. In the washing step, the quartz schist q and / or hot water h may be stirred in the container 1 to wash the quartz schist q, or the quartz schist q may be washed by hand washing in the container 1.

[0022] As shown in FIG. 1(b), the contact step is a step of placing the washed quartz schist q in a container (tank) 2, pouring macadamia nut oil m on the quartz schist q, and contacting the quartz schist q with the macadamia nut oil m. The container 2 used in this contact step has a capacity of 100 liters. The container 2 contains quartz schist q with a total weight of about 10 kg. In addition, the container 2 is filled with macadamia nut oil m in an amount of 80% or more of the container 2's capacity. A pipe 3 is connected to the bottom of the container 2. The pipe 3 is provided with a valve 4 for opening and closing the pipe 3, and a filter 5 for filtering the macadamia nut oil flowing through the pipe 3.

[0023] The contact step is carried out at room temperature (i.e., 15 to 25° C.) around the container 2 (e.g., the room temperature in which the container 2 is installed). Furthermore, the contact step is carried out by leaving the quartz schist q and the macadamia nut oil m in the container 2 for about 36 hours.

[0024] As shown in FIG. 1(c), the separation step is a step of separating the macadamia nut oil m that has been in contact with the quartz schist q from the quartz schist q that has been in contact with the macadamia nut oil m. This separation step is performed by filtering the macadamia nut oil m with a filter 5. Furthermore, the macadamia nut oil m separated in the separation step is filled into a container 6 for sale.

[0025] The cosmetic macadamia nut oil m obtained by the above-mentioned method for producing cosmetic macadamia nut oil is used for skin care, massage, hair care, cleansing, etc. For example, after washing your hair, before blow drying, you can apply a small amount to the ends of your hair as a leave-in hair treatment oil. This will prevent your hair from drying out and also make it easier to keep your hair in place after blow drying. For example, after washing your face and applying lotion as usual, you can apply a small amount to your hands and then wrap your face with both hands to use as a protective layer after applying basic skincare products. Doing this before applying foundation in the morning will give your skin a radiant look. Macadamia nut oil can also be used as a full body massage oil by applying it to the whole body after a bath and before getting dressed, which is especially recommended for dry, itchy skin. Furthermore, you can use it as special scalp and hair care by massaging the scalp thoroughly before shampooing, then wrapping it in a steamed towel and leaving it on for about 10 minutes, and then rinsing it off with shampoo. This is recommended when you are concerned about dry scalp and hair.

[0026] As described above, the cosmetic macadamia nut oil manufacturing method of this embodiment includes a washing step of washing the quartz schist q with hot water h, a contact step of putting the washed quartz schist q into a container 2, putting the macadamia nut oil m on the quartz schist q to contact the quartz schist q with the macadamia nut oil m, and a separation step of separating the macadamia nut oil m that has been in contact with the quartz schist q from the quartz schist q that has been in contact with the macadamia nut oil m. By contacting the quartz schist q in this way, it is possible to obtain cosmetic macadamia nut oil m that has been activated to deal with various skin troubles. In particular, it is possible to obtain cosmetic macadamia nut oil m that has extremely high skin permeability, good skin compatibility, and little stickiness.

[0027] In this embodiment, the contact step is performed by standing still, which does not require a complicated stirring process and effectively activates the macadamia nut oil m by contacting it with the quartz schist q.

[0028] In this embodiment, the contact step is carried out for about 36 hours at a temperature between 15 and 25° C. This allows the macadamia nut oil m to be effectively activated by contact with the quartz schist q at room temperature.

[0029] In the present embodiment, the washing step involves washing a plurality of quartz schists q with a maximum width of 5 to 30 mm with hot water h. This allows the quartz schists q to be effectively washed, and the macadamia nut oil m to be effectively activated by contact with a large number of relatively small quartz schists q.

[0030] Furthermore, in this embodiment, the separation step is performed by filtering the macadamia nut oil m with a filter 5. This allows impurities to be removed and the macadamia nut oil m to be effectively separated.

[0031] Next, we will explain sensory tests 1 and 2 using cosmetic macadamia nut oil obtained by the above-mentioned method for producing cosmetic macadamia nut oil (hereinafter referred to as "example oil") and cosmetic macadamia nut oil before undergoing each step of the above-mentioned method for producing cosmetic macadamia nut oil (hereinafter referred to as "comparative example oil").

[0032] In sensory test 1, five testers, A to E (chiropractors, etc.), performed massages on test subjects using the oils of the Examples and Comparative Examples and conducted evaluations. As a result, as shown in Table 1, the four testers, A to D, evaluated that the oils of the Examples had higher skin penetration than the oils of the Comparative Examples. Furthermore, the three testers, C to E, evaluated that the oils of the Examples were less sticky than the oils of the Comparative Examples.

[0033] [Table 1]

[0034] In sensory test 2, 19 testers, from Mr. F to Mr. X, who had used the oil of the embodiment on themselves, conducted the evaluation. As a result, as shown in Tables 2 and 3, many testers evaluated that their skin troubles, such as dry skin, rough skin, and eczema, had improved.

[0035] [Table 2]

[0036] [Table 3]

[0037] In addition, the present invention is not limited to the above-mentioned embodiment, and various modifications within the scope of the present invention can be made according to the purpose and use. That is, in the above-mentioned embodiment, the contact step is performed by leaving the macadamia nut oil m in the container 2, but the present invention is not limited to this. For example, the contact step may be performed by stirring the quartz schist Q and / or the macadamia nut oil m in the container 2.

[0038] In the above examples, the contact step is performed at room temperature (that is, 15 to 25° C.), but the present invention is not limited thereto, and may be performed at a temperature other than room temperature.

[0039] Furthermore, in the above embodiment, a separation process is exemplified in which macadamia nut oil m is filtered using filter 5, but this is not limited to this, and for example, the separation process may be performed by collecting the supernatant of macadamia nut oil m that has come into contact with quartz schist q in container 2.

[0040] The present invention is not limited to the above-described embodiments, and various modifications and variations are possible within the scope of the claims of the present invention. [Industrial Applicability]
