More particularly, the present invention relates to a bath composition containing a skin-care essential oil. More specifically, the skin-care composition contains a solubilizing agent for solubilizing a skin-care essential oil, The present invention relates to a bath composition capable of maximizing the aromatherapy effect and the like by keeping the fragrance continuously for a long time.

In general, bathing is used when bathing (bathing), which has recently been used increasingly in modern people. Most bath salts contain phytonutrients and fragrances, which are derived from plants and herbal medicines. They are harmonized with water in the bathtub to provide a psychological sense of security to the user, and their pharmacological components are absorbed through the skin of the user. It can also give the medical effect of healing the disease.

Bath additives include foaming and foaming bath additives that form bubbles when mixed in a bath, tea bath additives using petals or medicines, powder bath additives that can be used by dissolving functional ingredients in water, and essential oil bath agents that can give an aromatherapy effect.

For example, Korean Patent Publication No. 10-2007-0055184, Korean Patent Laid-Open No. 10-2012-0138351, and Korean Patent No. 10-1236366 disclose technologies relating to bath salts.

In recent years, attention has been paid to bath salts using cypress essential oil obtained from cottonwood. The phytoncide is much higher than the other trees in the untreated trees. In addition to the psychological stability, these phytoncides are known to enhance the peripheral blood vessels and enhance the cardiopulmonary function. Phytoncide also helps with bronchial asthma, treatment of pulmonary tuberculosis, strengthens the heart, and is known to have a pharmacological action to disinfect the skin.

In addition, it contains a large amount of phytoncide, which is effective for skin diseases such as allergic and sensitive skin, has powerful antimicrobial action, improves skin disease, and helps the bacteria penetrate into the skin while calming the itch. It is known to block. Especially, it is known that the incandescent essential oil inhibits the expression of proteins involved in causing atopic dermatitis, and is effective for improving atopic dermatitis, and has excellent aromatherapy effects such as stress relaxation and psychological stability.

However, the prior art bath additives containing the unilamellar essential oil have the following problems, for example.

First, the waxy essential oil is useful (water-insoluble) and is difficult to uniformly mix with water in the bathtub. Accordingly, when the untreated essential oil is put in the bath, the water (bath water) in the bath becomes opaque and unpleasant to the user, and most of the essential oil is floated to the surface of the water.

In addition, since the essential oil is a volatile component, it is volatile when it floats on the surface of water, so it is difficult to continuously dissolve the soft white scent (phytoncide flavor) for a long time. As a result, pharmacological effects, aromatherapy effects, and the like can not be sustained.

Hereinafter, the present invention will be described in detail. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known general functions and / or configurations will be omitted.

As used herein, the term "and / or" is used to include at least one of the preceding and following elements. The term "one or more" as used in the present invention means one or more than two.

The present invention provides a bath composition comprising a skin care essential oil. The bath composition according to the present invention is mixed with water and used in combination with water (bath water) in a bath during bathing (bathing), as well as mixed with water at the time of cleansing.

The bath composition according to the present invention is characterized in that it comprises: a facial essence oil; And a solubilizing agent for solubilizing the artificial essential oil in water. The bath composition according to the present invention has a clear liquid type solubilized formulation.

In the present invention, the artificial essential oils are the same as usual. The artificial essential oil is not particularly limited as long as it is obtained from cottonwood. The above-mentioned incomplete essential oil can be obtained by extracting the mouth, stem and / or root of the Japanese white rice tree by a solvent extraction method or a press extraction method. In one example, in the case of the artificial essential oil, as described above, the leaves obtained by using an essential oil extracting apparatus or extracted with a solvent such as ethanol and then concentrated under reduced pressure can be used.

In the present invention, the solubilizing agent may be any one capable of solubilizing (dissolving) the above-mentioned skin-prickly essential oil in water (bath water, etc.). According to the present invention, the solubilized essential oil is solubilized in water by the solubilizing agent to have transparency and is uniformly dispersed and mixed in water. At this time, micelles can be formed by the solubilizing agent, and these micelles belong to the colloidal dispersion system and perform Brownian motion in the solution. Accordingly, the solubilizing agent naturally mixes the essential oil of the woven base in the bath without physical means such as hand stirring when mixing it into the bathtub.

According to a preferred embodiment of the present invention, the solubilizing agent preferably includes octyldodecethes. Examples of the octyldodeceses include octyldodeceth-5, octyldodeceth-10, octyldodeceth-16, octyldodeceth-20 Octyldodeceth-20) and octyldodeceth-25 (octyldodeceth-20) and octyldodeceth-25.

In the formulation of the solubilization type, the combination of the substance to be solubilized and the solubilizing agent is very important. As a substance to be solubilized, a surfactant may be considered as a substance capable of solubilizing an oil component obtained from a plant. However, not all conventional surfactants are able to solubilize the essential oil, and even if it is solubilized, it must be used in large quantities. At this time, when a large amount of a surfactant is used, the skin may be adversely affected.

According to numerous experimental investigations of the present invention, it has been found that the octyldodeceses have a very excellent solubilizing power against the waxy essential oils than other surfactants in general. In addition, it was found that the octyldodeces, even if used in a low content, effectively solubilized the unilaminated essential oil, thereby providing skin safety.

According to a preferred embodiment, the bath composition according to the present invention preferably contains the skin care essential oil and the octyldodecase in a ratio of 1: 0.2 to 5 by weight. That is, it is preferable that the composition is a weight ratio of the unilamellar essential oil: octyldodecesulfate = 1: 0.2 to 5. At this time, when the amount of octyldodeces used is less than 0.2 weight ratio with respect to the unbleached essential oil, the solubilizing power by the use of octyldodeces may be insignificant. If the amount of octyldodeces used exceeds 5 parts by weight, the skin stability and the like may be deteriorated.

In addition, the bath composition according to the present invention may further comprise at least an essential oil and an octyldodecase, and may further include an alcohol and a humectant according to a preferred embodiment. Specifically, the bath composition according to the present invention may comprise a plain essential oil, octyldodeces, an alcohol and a humectant. At this time, for example, ethanol and / or isopropyl alcohol can be used as the alcohol, and ethanol can be preferably used. The moisturizing agent is not particularly limited as long as it has a moisturizing function. The moisturizing agent is, for example, at least one selected from the group consisting of glycerin, 1,3-butylene glycol, propylene glycol, dipropylene glycol, glycereth- Is preferably used.

The bath composition according to the present invention may further comprise water (purified water), and may further include at least one additive selected from pigments, preservatives, natural plant extracts, herbal medicine extracts and / or oxidative stabilizers and the like have. Such additives may be selected from those conventionally used.

According to a preferred embodiment, the bath composition according to the present invention comprises 0.1 to 5% by weight of a waxy essential oil, 0.2 to 5% by weight of octyldodeces, 1 to 15% by weight of alcohol and 5 to 30% by weight of a moisturizing agent %. And the balance may be water (purified water) and / or additives.

At this time, when the content of the artificial essential oil is less than 0.1% by weight, the effect (pharmacological effect and aromatherapy effect, etc.) of its use may be insignificant, and when it exceeds 5% by weight, Formulation stability and the like may be deteriorated.

When the content of octyldodeceses is less than 0.2% by weight, the solubilizing power of octyldodeceses may be insufficient. In addition, if the content of octyldodeces is less than 0.2% by weight, the formulation stability may be deteriorated. If the content of octyldodeces is more than 5% by weight, the skin stability and the like may be deteriorated.

In addition, when the alcohol and the humectant are lower than the above range, the effect of dilution, disinfection and / or moisturizing is small depending on their use, and when the amount exceeds the above range, the synergistic effect due to excessive use is not so large The content of the other components may be lowered. The water (purified water) as the balance may contain, for example, 50 to 80% by weight, and the additives may be included in the range of 0.001 to 10% by weight, for example, within the range of not lowering the effects of the respective components.
Further, the present invention provides a method for producing a bath composition as described above, comprising the steps of: preparing a textural essential oil obtained from a cottonwood; Mixing an alcohol and a solubilizing agent in the artificial essential oil, and stirring the solution to prepare a solution of an alcoholic phase; Preparing an aqueous solution in which purified water and a moisturizing agent are dissolved; And stirring the aqueous solution in the aqueous solution while stirring the aqueous solution, thereby stirring the aqueous solution. At this time, octyldodeceses are used as the solubilizing agent in the step of preparing the alcoholic solution, and the wollastonite essential oil and octyldodeces are mixed and stirred at a weight ratio of 1: 0.2 to 5.

According to the present invention described above, the artificial essential oil does not float on water but uniformly mixed with water in the bath, including octyldodeceses, which solubilizes the artificial essential oil in water, and has a transparent appearance. In addition, the soft white scent (phytoncide flavor) can be maintained for a long time, and the pharmacological effect and the aromatherapy effect can be maximized. And has formulation stability and skin stability.

Hereinafter, examples and comparative examples of the present invention will be exemplified. The following examples are provided to illustrate the present invention in order to facilitate understanding of the present invention, and thus the technical scope of the present invention is not limited thereto. In addition, the following comparative example is not meant to be a prior art, but is provided for comparison with an embodiment only.

[Examples 1 to 3]

The skin care essential oils obtained from the cotton wool were prepared, and then the bath composition was prepared by the following composition ratios (ingredients and contents) as shown in Table 1 below.

Firstly, a waxy essential oil, ethanol and a solubilizing agent (octyldodeces) were thoroughly mixed and stirred at a temperature of about 45 캜 at a composition ratio shown in Table 1 below to prepare a solution in ethanol. Separately, an aqueous solution was prepared by dissolving purified water and humectant components at room temperature. While the aqueous solution was stirred with a Disper Mixer, the ethanol solution was slowly added thereto, and the mixture was stirred for 10 minutes. At this time, as shown in Table 1 below, the kinds of the solubilizing agent (octyldodeceses) were varied according to each example. In the following Table 1, the content (% by weight) of each component is based on the total weight of the bath composition.

[Comparative Examples 1 and 2]

The procedure of Example 1 was repeated except that castor oil was used instead of octyldodeces. Specifically, PEG-40 hydrogenated castor oil (Comparative Example 1), which is mainly used as a surfactant in the field of cosmetics instead of the octyldodeceses, without adding octyldodeceses, And PEG-60 hydrogenated castor oil (Comparative Example 2) were used.

<Customer Sensibility Test>

The sensory evaluation tests were conducted to determine the customer satisfaction according to the content of the essential oil and the content of octyldodeces (solubilizing agent) in the bath composition containing the essential essence.

Twenty women, aged 20 ~ 35 years, were evaluated for each item. At this time, 100 ml of the bath composition according to each of the Examples and Comparative Examples was mixed into a bath filled with water according to the general bath agent method, and then the satisfaction of the aromatherapy effect and the skin stability were evaluated. The evaluation criteria are as follows. The adult women were evaluated for their scores on the aromatherapy effect and skin stability according to the following evaluation criteria, and then the results were averaged. The results are shown in Table 4 below.

<Formulation stability>

In order to evaluate the formulation stability of the composition of the bath composition with respect to the content of the essential oil and the content of octyldodeces (solubilizing agent), the following evaluation was made.

The bath composition according to each of the above Examples (1 to 8) was stored in each of the thermostats at -15 ° C, 0 ° C, 40 ° C and 45 ° C for 4 weeks in order to evaluate the formulation stability against the temperature, The results are shown in Table 5 below. At this time, when there was no separation phenomenon, "good" and when separation phenomenon (observation of opaque or aggregate (suspension)) occurred, it was evaluated as "insufficient".

                      <Results of Formulation Stability Evaluation> Remarks Example One 2 3 4 5 6 7 8 Content of Pruning Essential Oil
(weight%) 0.1 0.1 0.1 0.5 1.0 1.5 1.0 1.0 Octyldodecene content

First, as shown in Table 4, it can be seen that the bath composition according to the examples of the present invention has a very good sensory evaluation result (customer satisfaction).

In addition, it can be seen that satisfaction is varied depending on the amount of octyldodeces used for the artificial essential oil. That is, the results of Examples 1 and 4 to 5 are superior to those of Examples 7 and 8.

In addition, as shown in Table 5, it can be seen that the formulation stability varies depending on the amount of octyldodeces used relative to the unbleached essential oil. That is, when the amount of octyldodeces used is low (Example 7), it can be seen that the formulation stability is poor at low temperatures. On the other hand, in the case of Comparative Examples 1 and 2, formulation stability was not evaluated because it was opaque even at room temperature and there was a float.

As can be seen from the above-mentioned experimental examples, octyldodeceses can effectively solubilize the essential oil in a low content in comparison with a general surfactant (for example, castor oil) to provide excellent transparency, customer satisfaction (aromatherapy effect And skin stability) and formulation stability, and the like. In addition, when the amount of octyldodeceses is 0.2-5 weight ratio (based on the total weight of the composition, 0.2-5 (in terms of the total weight of the composition) (When used in a weight percentage).
