The present invention relates to a cosmetic composition with aromatherapy effect containing citron extract, aroma complex hydrosol, and herbal medicine concentrate, and a method for producing the same.

To maintain healthy skin, active ingredients must be supplied from outside the body, such as in cosmetics. For basic care, the use of these natural materials is rapidly increasing along with the addition of active ingredients extracted and isolated from nature. In particular, due to the nature of the manufacturing of fragrances and cosmetics, essential oils and herbal extracts are mainly used, so natural extracts are a large area that is difficult to overlook in the fragrance industry. In Europe, especially France, mass production of essential oils used as fragrances is being achieved thanks to the availability of high-quality, abundant aromatic plants as raw materials and the development of essential oil production facilities. In addition, as problems caused by side effects of synthetic fragrances arise around the world, research on the development of natural fragrances is actively underway.

Aromatherapy is also known as scent therapy. This refers to natural therapy that aims to maintain homeostasis in the human body by restoring the balance of the body and mind using the scent and medicinal effects of plants. In addition to pure aromatherapy, there are also products that use cosmetics, air fresheners, perfumes, and air fresheners. However, if the concentration of the aroma is too strong, if you smell it for a long time, or if you consume essential oil without a doctor's prescription, it may cause side effects, causing allergies or adverse skin reactions. In particular, plants with scent and medicinal properties are used in aromatherapy treatment, and among them, natural essential oils extracted from plants are mainly used. Aromatherapy using natural essential oils has a variety of effects, including relieving stress, improving immunity, increasing the body's healing ability, and helping cell regeneration.

Accordingly, the inventors of the present invention studied to develop a cosmetic composition that has aromatherapy efficacy while reproducing a unique and fragrant scent by mixing citron extract, aroma complex hydrosol, and herbal medicine concentrate in an appropriate ratio, and completed the present invention.

In one embodiment of the present invention, the formulation of the cosmetic raw material (cosmetic composition) that forms the basis of the citron serum was evaluated in three stages.

“Cosmetic composition” of the present invention refers to cosmetic raw materials, and in the present invention, it refers to some components included in the cosmetic composition. In the production examples of the present invention, formulation examples were prepared at various mixing ratios to prepare cosmetic raw materials.

Specifically, the emulsibility of the formulation was first evaluated by the amount of citron extract added, and the degree of stabilization was evaluated by adding sodium hyaluronate (Na Hyaluronate) secondarily within the range of the amount of citron extract added to the primary formulation selected as a result of the evaluation. did. Afterwards, the herbal medicine concentrate was added a third time to the secondary formulation selected as a result of the secondary evaluation, and the final degree of stabilization and feeling of use were evaluated.

In one embodiment of the present invention, primary and secondary serum formulations were prepared, and a sensory evaluation was performed on them. As a result, Formulation Example 18, in which 0.1% of citron extract was added, had excellent fragrance characteristics and the formulation color was transparent, so it was finally selected. It was evaluated as suitable (Experimental Example 2). In addition, Formulation Example 21, in which 0.1% of functional complex essential oil was added, exhibited a balanced citrus and herbal scent with a floral scent, and the skin lingering scent also showed a subtle citrus herb scent with a floral scent, so it was ultimately evaluated as the most suitable (Experimental Example 3) .

The citron extract of the present invention includes citron oleoresin, citron distilled extract oil, and citron hydrosol.

Compared to other fruits, "Yuja citron" of the present invention contains many beneficial ingredients for developing resistance and immunity, such as vitamin C, citric acid, and folic acid. In particular, it is known to have the highest content of vitamin C, an antioxidant called a natural cancer treatment, among fruits harvested in late fall. The main essential oil components distilled from yuzu include 1R-alpha-pinene, (-)-β-Pinene, tricyclene, α-Thujene, and limonene. (limonene), 3-carene, Terpinolene, Linalool, alpha-terpineol, dl-beta-farnesene ((E)-beta-farnesene ), Bicyclogermacrene, etc. The results of analysis of major aroma components showing the functional effects of citron essential oil using GC-MASS for essential oil distilled from citron are as follows (Table 1).

“Oleoresin” of the present invention refers to an aromatic substance secreted from various plants, extracted only from essential oil components with fragrance, color, and taste. Therefore, citron oleoresin of the present invention refers to an aromatic substance extracted from citron.

“Distillation extraction” of the present invention means extracting a substance using steam distillation. Steam distillation is a method of extracting essential oil by distilling steam and is divided into water distillation, water-steam distillation, and steam distillation.

Water distillation is a method of heating oil raw materials in water, cooling the resulting steam and essential oil, and then separating the water and oil. Because the raw materials are immersed in boiling water, they do not come into direct contact with water vapor. It is suitable for orange flowers and roses, which turn into lumps when they come in direct contact with water vapor. The water-steam distillation method is a method in which oil raw materials are layered on a grid installed inside the distillation unit, water is heated from below, and as the distilled water vapor passes through the sample, the separated volatile essential oil components are mixed with the water vapor. Plant raw materials have the advantage of not overheating because they do not come in contact with water, so they are mainly suitable for plants that require medium boiling points, such as some seeds, fruits, pericarp, some flowers, sentinels, and leaves. Steam distillation is the most common oil extraction method and involves collecting essential oil by putting raw materials in a distillation kiln and blowing steam from the bottom. It is a distillation method that mainly requires a low boiling point. The steam distillation method extracts essential oils using steam (water), so it has little toxicity and has the advantage of being safe for skin application.

The term “hydrosol” of the present invention comes from the Latin words hydro, meaning water, and sol, meaning decomposition, and is also called aromatic distilled water or hydrosol water. Hydrosols are obtained through the process of producing essential oils or by distilling plants to obtain pure hydrosols. When plants are steam distilled, essential oil, which is an oil component, and hydrosol, which is a water component, are produced. Hydrosol contains essential oil, although at a low concentration. In addition, hydrosol has a preservative and sterilizing effect, adjusts the pH of the skin, provides a moisturizing effect to the skin, and prevents skin diseases and allergic reactions, so it is used as a main ingredient in natural cosmetics.

In particular, the aroma hydrosol produced using the steam distillation device patented through this research and development contains water-soluble active ingredients and a trace amount of 0.02-0.05% aroma oil, retaining the characteristics of essential oil. In addition, it has the advantage of being milder and safer than essential oils and contains the unique scent of essential oils and water-soluble functional ingredients, so it is used as a raw material for lotions, skin toners, and cosmetics. In addition, the hydrosol obtained through the distillation extraction process has the advantage of removing various bacteria and microorganisms, and the low acidity of the water makes it difficult for microorganisms to reproduce, so it has the advantage of being able to be stored for a relatively long period of time, so it has the optimal conditions as a raw material for lotions, which are the main ingredients of more than 99% like serums. there is.

The water-steam distillation machine, a mass production device for natural essential oils and distilled extracts, is a patented device developed by this researcher and includes a 150kg (internal volume) distillation unit, a cooling condenser, a pressurizing device, and a vacuum pump for decompression. It is a device that facilitates the extraction of active ingredients by adjusting the extraction time and cooling temperature according to the conditions of the sample.

When producing natural essential oil using a steam distillation extractor, the natural hydrosol production method is to put a certain amount of sample to be extracted into the inner pot of the distillation extractor, add distilled water to the extraction sample at a certain ratio, keep the extraction temperature and cooling temperature constant, and produce hydrosol. Essential oil and hydrosol were extracted simultaneously while keeping the production rate constant. The hydrosol produced at this time was used instead of existing purified water generally used in serum production. In order to use the aroma hydrosol as it is without diluting it, the hydrosol with the concentration adjusted by adding or subtracting purified water as a solvent before extracting the natural essential oil was used as is. Raw material conditions for hydrosol production were extracted from living organisms. The hydrosol production method for each raw material was extracted using the same method as the amount of purified water added to the dried and biological samples presented in the herbal medicine concentrate.

[Preparation Example 2] Preparation of mixed herbal concentrate

The method of extracting the herbal medicine concentrate was the Water-Steam Distillation System (Patent No. 10-1105539) used in this research and development.

As a method for producing herbal concentrate, first prepare the herbal ingredients to be concentrated, then hang a shelf in the inner pot of the distillation extractor for each herbal medicine sample to avoid contact with purified water, which is the extraction solvent, and stack a certain amount of herbal ingredients on the shelf. When the purified water in the inner pot of the distiller is heated, the water vapor rises and passes through the oriental medicine ingredients. The oriental medicine ingredients are heated and decomposed by the medium, and the useful substances of the fine herbal medicine dissolved in water pass through the cooling pipe in the form of steam to produce natural essential oil and natural hydrosol. do. On the other hand, the vapor containing the useful substances of the herbal medicine that did not pass through the cooling tube is condensed and falls into the inner pot, where it is heated again and passes through the herbal medicine ingredients in a vapor state, condensing again and falling, while the useful substances of the herbal medicine are contained in the inner pot of the distillation extractor. This becomes concentrated. During distillation and extraction for a certain period of time, the purified water in the inner pot decreases and the useful substances in the herbal medicine are concentrated to a high concentration. At this time, the highly concentrated concentrate in the inner pot was filtered and used as an herbal concentrate. In the case of an inner pot of a distillation extractor with a capacity of usually 50L, dried herbal medicines are distilled and extracted in two times with a total of 50L of purified water per 5kg of sample, and biological samples are distilled and extracted in two times with a total of 50L of purified water per 10kg, so that the total concentrate capacity of the inner pot is 10%. Phosphorus is distilled and extracted until 10L is reached. The total distillation extraction time is 25 to 28 hours for dried medicinal materials and 10 to 12 hours for living organisms. The oriental herbal concentrate of each raw material extracted by distillation contains useful water-soluble and fat-soluble substances and pigments that are finely decomposed while passing through distilled water vapor. It is slowly distilled and extracted at a low temperature of 100°C for a long period of time to prevent the oriental herbal medicinal ingredients from being destroyed and is good for skin absorption. It is broken down into fine components, so it is different from the water extract of regular herbal medicine.

Distillation produced after low-temperature distillation of Angelica root, Houttuynia cordata, green tea, peony flower, Cheongung, and pomegranate, which help improve skin's blood circulation, soothing effect, and immunity, as well as licorice, astragalus, and goldenrod, which help with anti-inflammatory and antibacterial properties. The concentrates were mixed to prepare a complex herbal concentrate. In order to provide antibacterial and moisturizing properties and act as a solvent, a complex herbal concentrate containing rosemary oleoresin, glycerin, and butylene glycol was used as a functional additive for highly concentrated citron essence.

The functional mixed herbal concentrate (Mixed Herbal Concentrate) was prepared with the ingredients shown in Table 8 below. Angelica root, Houttuynia cordata, licorice root, green tea, peony flower, Tocheongung, astragalus, goldenrod, and pomegranate extracts were mixed and included at 90% by weight based on the total weight of the herbal concentrate. In addition, rosemary oleoresin extract, glycerin, and butylene glycol were added to prepare the final herbal concentrate (Table 8).
