Other objects and applications of the present invention will become apparent to those skilled in the art from the following detailed description.

Hereinafter, the present invention will be described in detail.

Pine is classified as the genus Pinus: P. palustris Miller (North America), P. pinaster Aiton (France), P. sylvestris L (Europe), P. laricio Poiret (Austria), P. longifolia Roxburgh (India), P Terpenes from densiflora Sied, et Zucc. (Korea, Japan), P. thunbergii Palatore (= Haesong; Korea, Japan), etc. are mainly used in industry, and the main ingredient of pine needles is Terpennetine oil. , Cineole, Salinigrin, Coniferin, P-Cymen, Densipimaric acid, Retene, etc. Chlorophyll, protein, low fat, phosphorus It also contains iron, enzymes, minerals, fat-soluble vitamins A and C. The types and contents of these main components in pine needles vary slightly depending on the species and the season taken.

According to the present invention, the extract obtained by extracting the leaves of the pine having the active ingredient as described above, or the essential oil obtained by steam distillation, or the extract complex obtained by reacting the extract with a cationic polymer surfactant alone or by mixing the human cleanser It is characterized by blending into the composition.

According to another aspect of the present invention, the human cleanser composition of the present invention further contains a hinoki oil or cedarwood oil alone or in combination to further enhance the forest bathing effects such as fatigue and deodorant effects of the body and body. It is done.

As used herein, the term "pine needle extract complex" refers to a complex obtained by stirring an extract obtained by extracting a pine needle with a solvent together with a cationic polymer surfactant.

Obtaining pine needle extract and pine needle essential oil can be carried out according to a conventional method for extracting the active ingredient from the real thing, the present invention is not limited by the method. However, as a preferred method, the pine needle extract has a weight ratio of pine needles and a solvent by using a mixed solvent in which the weight ratio of 1,3-butylene glycol and ethanol (95%) is 1: 1 to 1: 2. It can manufacture by the method of being in the range of 1: 1 to 1: 3. On the other hand, pine needle essential oil can be obtained by the method of steam distilling the cut pine needles.

As described above, the human cleanser composition of the present invention containing sole or mixture of pine needle extract, pine needle essential oil, or pine needle extract complex, and optionally single or mixture of hinoki oil or cedarwood oil, is effective for promoting skin circulation of the skin. It has the effect of healing beauty effect and eczema, sound and sweat band, and contains ingredient of phytonside, which has antibacterial effect, air purifying effect and neutralizing deodorizing effect of odor, and forest bath effect.

When the pine needle essential oil and pine needle extract used in the present invention and the preparation method of the composite according to the production examples in detail as follows.

Preparation Example 1.

Pine needle oil (Pine Needle Oil) manufacturing method.

One kilogram of leaves and Twigs of P. pinaster Aiton (France) were cut to 1.0 to 2.0 centimeters and 10 kilograms of distilled water was added to prepare 80 grams of pine needle essential oil by steam distillation at high temperature.

Preparation Example 2.

Method for producing fine oil.

Steam distillation is carried out as in Example 1 on the leaves and fragile branches of P. palustris Miller (North America). At this time, there are useful components in the interior of the tree, and this is again vacuum fractionated to obtain 50 grams of fine oil.

Preparation Example 3.

Method for preparing pine needle extract.

The method for preparing pine needle extract is obtained by cutting the collected pine needles into 1.0-2.0 cm size, and then immersing them in a solvent for 24 hours or more and compressing them. In this case, the weight ratio of 1,3-butylene glycol and ethanol (95%) is 1: 1 to 1: 2, and the weight ratio of pine needles and solvent is 1: 1 to 1: 3.

Preparation Example 4.

Method for preparing pine needle extract composites.

The collected pine needles were dried in coagulation, and then added to 4 kg of 20% ethanol aqueous solution, stirred at 50 ° C. for about 5 days, extracted and filtered through a filter cloth of 200-300 mesh wire mesh, followed by cationic polymer polyquaternium- of surfactant. 50 grams of 7 was added to form a stirred composite, filtered through a 200 mesh filter cloth, and evaporated to dryness in vacuo to obtain about 32 grams of dried material.

As in Preparation Example 1, the main component of Pine Needle Oil extracted from P. pinaster Aiton (France) is 550-60% of Monoterpenes, and 20-Sesquiterpenes of Sesquiterpenes. 30%. Monoterpenes contain more than 50% alpha-pinene (38.32%) and beta-pinene (β-Pinene, 28.14%), and are carene, beta-marcene and limonene ( Components such as Limonene).

Pinus densifloria Sied. The pine needle essential oils obtained from et Zucc.'s needles include alpha-pinene (α-pinene, 35.7%), beta-pinene (β-Pinene, 5%), beta-mycene (β-myrcene, 18.8%), Beta-phellandrene (12.7%), dipentene (5.4%), camphene (3.6%), beta-caryophyllene (β-Caryophyllene, 5.93%), germacrene di D, 2.31%).

The main components of the pine oil obtained as in Preparation Example 2 were sesquiterpene alcohols, ketones, terpineol, penchylalcohols, and borneol. , Fenchon and estragole.

As seen above, the components contained in each species or depending on the site of extraction are different, but the main component of pine needles is alpha pinene among terpenes. These terpene components have different flavors of pine needle essential oils according to each species of pine, but are the main substances exhibiting the forest bathing effect in all species.

It is known that coniferous forests are effective due to the smell of various complex plants as well as the terpene system.

It was discovered by the present inventors that a combination of a coniferous tree, Hinoki Oil and Cedarwood Oil, such as a small amount of pine needle essential oil, has a synergistic effect of the forest bathing effect. It is known that hinoki oil has soothing, bronchodilating and concentration enhancement effects. Cedalwood oil is known to have antiseptic, antiseptic, soothing and bronchodilating effects.

The human cleanser composition of the present invention may contain 0.1 to 10% by weight, preferably 0.1 to 5.0% by weight of the total weight of the composition of the pine needle extract, pine needle essential oil, or pine needle extract complex alone or in a mixture. When the pine needle extract is used less than 0.1% by weight, the effect of skin beauty and bactericidal power is weak, and when using more than 10.0% by weight, the bubble is worsened and a slight separation phenomenon is found within a month.

Pine needle oil may be used in an amount of 0.01 to 9.0% by weight, and may preferably contain 0.1 to 4.5% by weight. When the pine needle essential oil is contained in less than 0.01% by weight, the specific odor of pine needles is weak, and it is difficult to show the skin cosmetic effects such as deodorization. When the pine needles contain more than 9.0% by weight, the pine needle's specific odor is too strong and irritation occurs on sensitive skin.

And it was found that the synergistic effect was recognized when the amount of hinoki oil and cedarwood oil used to enhance the forest bathing effect were in the range of 0.05 to 0.5wt%, respectively.

The human cleanser composition provided according to the present invention may take a conventional dosage form, and conventional ingredients other than its dosage form or characteristic ingredients according to the present invention may be determined by those skilled in the art. For example, a commonly used raw material is a liquid soap system, a synthetic surfactant system, or both systems neutralized with fatty acids and alkaline substances as main components for cleaning, and is used to give skin softening effects. Conventional raw materials such as oils, waxes, fatty alcohols, hydrocarbons and natural animal proteins are used, and conventionally known wetting agents such as glycerin, propylene glycol, ethylene glycol and sorbitol can be used to moisturize the skin. In addition, fragrances, pigments, metal ion sequestrants, antioxidants, preservatives, and the like commonly used in human cleansers may be used, and inorganic salts, natural gums, synthetic polymers, and the like may be used to improve physical properties.

The fragrance components used in the present invention have a weakness in that the fragrance is weak due to strong volatility in the product. In order to complement the fragrance persistence, the above-mentioned disadvantages can be solved by using a composite of the pine needle component and the cationic polymer of the surfactant as in the aromatic component as in Preparation Example 4.

In the examples described below, 0.1: 1: 1 weight ratio mixture of three components of pine needle essential oil, pine needle extract, and pine needle extract complex was used as a pine needle component. The types of human detergents are largely liquid soaps, surfactants, and liquid soaps. The formulation was divided into a combination of surfactants and various formulations were compared according to the type of fatty acid and neutralizing agent.

In the present embodiment, the use of a mixture of the three components described above, but the present invention is not limited to this, but also includes the use of these components alone or in combination of two or three kinds of ratios, respectively. do.
