DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lotion composition using corn cob (CORNCOB), which is a pulverized corn cob. To provide.

[0002]

2. Description of the Related Art Cosmetic compositions such as lotions have generally been mixed with a fragrance in accordance with the taste of the user. However, this fragrance is usually extracted from animals and plants,
It is often a water-insoluble component synthesized from petroleum or the like.
Therefore, in order to blend a fragrance into a cosmetic composition such as a lotion, it is necessary to solubilize or emulsify, and various surfactants and solvents such as alcohols and polyhydric alcohols have been used. . As a result, there are the following problems.

[0003] Surfactants and various solvents used for solubilizing or emulsifying oily components cause skin irritation. The fragrance solubilized or emulsified by the surfactant easily stays on the skin, and the scented fragrance may cause skin irritation. When solubilizing or emulsifying a fragrance with a surfactant, the fragrance is taken into the micelles of the activator, and the fragrance of the fragrance deteriorates.Therefore, it is necessary to increase the amount of the fragrance, and as a result, further skin irritation occurs It will be easier. In addition, depending on the composition of each fragrance, it is necessary to use a different solubilization technique in order to be solubilized in cosmetics, and for that purpose, special technical knowledge is required. The odor of the surfactant or various solvents used gives the user discomfort.

In order to solve these problems, various attempts have been made to develop surfactants and fragrance materials which do not cause skin irritation, to mix irritation-reducing agents, etc., and to develop fragrance-free cosmetics. And each has some effect,
It does not meet the demands of consumers.

[0005]

DISCLOSURE OF THE INVENTION In view of these conventional problems, the present invention makes it possible to easily perfume an aqueous cosmetic composition such as a lotion without using a surfactant, An attempt was made to obtain a cosmetic composition having a good feeling of use in consideration of safety aspects such as skin irritation.

[0006]

SUMMARY OF THE INVENTION The present invention has been achieved by using corn cob, which is a ground corn cob. That is, a water-insoluble oily component is impregnated into the ground corn cob, and a cosmetic composition having an appropriate scent can be obtained by putting the ground oil-impregnated corn cob into water, further,
By using the powdered water-soluble composition in combination, it is possible to obtain appropriate moisturizing properties on the skin and cosmetic effects.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The crushed corn cob used in the present invention is a crushed corn cob, and is obtained by drying, crushing and sizing the cob remaining after corn is removed. It is also listed as a corn cob grain in the non-standard component standard, and is usually used as a scrubbing agent in a detergent or the like. This ground corn cob is usually a white, odorless granular material,
The desired particle size can be obtained.

The particle size of the ground corn cob used in the present invention is suitably from 150 μm to 4.50 mm, more preferably from 590 μm to 3.15 mm. When blended in a lotion, it is necessary to separate at the time of use, and if the particle size is smaller than this, it becomes difficult to separate. On the other hand, if the particle size is larger than this, the solubilization of the impregnated oil component in water becomes poor, and the initial purpose cannot be achieved.

The oily component used in the present application includes a fragrance composition in which various fragrance components are mixed, vegetable liquid oils such as olive oil, synthetic liquid oils such as liquid paraffin and silicone, and animal liquid oils such as squalane. Is done. The compounding amount of these oily components is 0.00 to the ground corn cob.
1% to 15.0% by weight is suitable, preferably 0.01% to 10% by weight.

When the content is less than 0.001% by weight, when a ground corn cob impregnated with the corn cob is put into water, its fragrance is weak and a peculiar odor of corn is generated. On the other hand, impregnation of 15% by weight or more is not preferable because oily components exude without being absorbed in the pulverized corn cob.

As the fragrance component used as the oil component, the following are usually used. Squeezed vegetable and animal oils as natural flavors, extracted by solvent extraction, steam distillation, etc., such as lavender oil, peppermint oil, oak moss oil, citronella oil, jasmine oil, tea tree oil, rose oil, orange oil, turpentine oil, etc. Usually used.

Synthetic fragrances obtained by isolating chemical components from plant and animal essential oils, derivatives thereof, and those newly synthesized using organic synthesis methods, such as linalool, geraniol, limonene, citronellol, l-menthol,
Examples thereof include vanillin, ionone, galaxolide, cyclopentadecanolide, liral, and cyclamenaldehyde. These can be used alone or in combination as a compounded flavor.

In the present invention, various compositions are blended in order to improve the usability of the lotion composition. Desirably, water-soluble substances which are solid at room temperature are desirable. Mix and mix with the ground pulverized material. The ground corn cob is usually used as a dry powder. If water is contained, mold and the like are generated, and there is a problem in storage stability.

Examples of water-soluble substances which are solid at ordinary temperature include sodium hyaluronate, collagen, amino acids, sodium chondroitin sulfate, dl-
Pyrrolidone carboxylic acid, calcium pantothenate, xylit, etc., citric acid, malic acid, tartaric acid as pH adjusters, powdered alcohol, carboxyvinyl polymer, water-soluble polymers such as xanthan gum as a feeling-improving agent, and phosphoric acid as antioxidant L-ascorbyl magnesium,
Glycyrrhizic acid as an anti-inflammatory agent, such as propyl gallate,
Examples include guaiazulene and the like, urocanic acid and the like as an ultraviolet ray inhibitor, water-soluble sulfur, photosensitizer, urea, benzoate and the like as antibacterial bactericides, and other natural and synthetic pigments, and powder extracts extracted from animals and plants. These can be added in an amount of 0.001% by weight to 200% by weight based on the ground corn cob.

In the composition of the present invention, a certain amount of an oily component is added to a ground corn cob in a dry state, and the mixture is stirred and mixed under the same drying conditions until homogenized, and then a certain amount of a water-soluble component is added. Then, by uniformly dispersing and stirring, a lotion composition is obtained, and by adding this to a certain amount of purified water, the lotion composition of the present invention can be obtained.

The content of the lotion composition in the purified water is suitably from 1% by weight to 10% by weight, and can be changed as appropriate depending on the composition and the amount of the oily component and water-soluble component mixed.

These lotion compositions are added to purified water and then used as a lotion composition. Before use, the corn cob pulverized matter added in advance is removed by an appropriate means. If you keep it, it is easy to use. For this reason, the pulverized material can be put in an appropriate bag, mesh, or the like to form a toy bag.

Example 14: Mist type lotion composition 5 g of the lotion composition obtained in Example 13 and 100 g of purified water
In a mist container provided with a mesh at the tip of the dip tube, and sufficiently stirred to obtain a mist lotion composition.

Stability test 1: An experiment was conducted to confirm the solubility of the perfume base in water. Evaluation sample (1): corn cob pulverized product (92
g) and rose flavor (8 g) are mixed uniformly, and 4 g of the mixture is mixed.
Was added to 100 g of purified water and stirred, and an evaluation sample (1)
And Evaluation sample (2): Rose flavor (0.32 g) was added to 100 g of purified water and mixed with stirring to obtain an evaluation sample (2). Evaluation sample (3): corn cob pulverized product (92
g) and rose flavoring (8 g) are uniformly mixed, and further powdered sodium hyaluronate (0.05 g) and citric acid (0.01 g) are mixed and mixed well. 4 g of the mixture was added to 100 g of purified water and stirred to obtain an evaluation sample (3).

<Methods and Results> Observe the stability of these evaluation samples immediately after stirring and standing and one day after standing.

From the above results, it is apparent that impregnating the ground corn cob with the perfume base enables it to be very stably dissolved in a water-soluble solvent without using a solvent such as a surfactant. The feeling of use was compared for the same formulation.

<Method and Results> In order to remove excess oil and corn cob pulverized matter from each evaluation sample, filtration was carried out, and then an appropriate amount was dropped on the back of the subject's hand, and spread while using the palm. An evaluation sample (1) An evaluation sample (2) An evaluation sample (3) A moist feeling +-++ A space feeling + + ++ Sticky ±--Scent standing + + + Evaluation criteria: +: Excellent ±: Somewhat excellent-: None

From the above results, it has been clarified that an aqueous solution having a better feeling of use can be obtained by putting the ground corn cob into which the fragrance component has penetrated into water. In addition, by using the water-soluble powder in combination, it was possible to more synergistically obtain an aqueous solution having a good feeling in use. Next, comparison was made on the residual scent of the scent.

Evaluation sample: The floral fragrance composition (8 g) was added to the dried corn cob crushed product (92 g) while stirring, and mixed uniformly. 0.4g
Was added to 100 g of purified water and stirred to obtain an evaluation sample. Evaluation sample: 0.03 g of floral flavoring agent, 0.5 g of polyoxyethylene hydrogenated castor oil as an activator were heated and mixed, and charged and stirred in 99.87 g of heated purified water.
Use it as an evaluation sample.

<Methods and Results> In order to remove the corn cob pulverized matter of the evaluation sample, after performing filtration, the state of the scent on the odor paper was evaluated sensoryly, and an appropriate amount was dropped on the back of the hand of the subject. After spreading with palms, the scent was evaluated again.

Evaluation Sample Evaluation Sample Appearance Transparent Almost transparent Perception of scent (bottle opening) ++ Perception of fragrance (back of hand) ++ Persistence of fragrance (back of hand)-+ Evaluation criteria; +: Strong. ±: weak, slightly,-: none

From the above results, when applied on the skin,
Because of the high scent retention due to the presence of the surfactant,
It is suggested that the fragrance stays on the skin together with the surfactant.On the other hand, when the product of the present invention is used, it emits a scent with a sufficiently real feeling at the time of use, but has no residual scent after use. From this, it was predicted that the fragrance did not stay on the skin, which revealed that the cause of skin irritation could be eliminated.

[0042]

Although the examples given above are only a few examples, such inventions can easily and stably produce a sufficiently palatable scent even though no surfactant is used. It was possible to obtain a cosmetic composition that could be retained, had low irritation, and had a good feeling of use.
