COSMETIC COMPOSITION FOR DEODORIZATION -

The present invention relates to a cosmetic composition for reducing body odor, and more particularly, to a cosmetic composition containing a mixture of triclosan acid, bamboo salt and tocopheryl acetate, which has an effect of drastically reducing the odor of main volatile components that cause unpleasant body odor, ≪ / RTI >

Echinacea sweat, apocrine sweat, sebum, contaminants, etc. are involved in body odor, and it has the specificity that cause and odor are different according to body part. In the case of odorants, which are the most troubling of body odor, odorless apocrine sweat is caused by the decomposition of axillary and airborne pathogens. There are many reports of microorganisms related to odor, but it is likely that odor is generated by lipophilic diphtheroid or large colony diphtheroid. As a result, microorganisms are decomposed and volatile odor substances are generated. These include low-grade fatty acids such as caproic acid, caprylic acid, isovaleric acid, butric acid ), Ammonia, amines, indoles, mercaptans, hydrogen sulfide, phosphines, steroids, and the like. Particularly, isovaleric acid among lower fatty acids, 5-alpha-androst- 5α-androst-16-en-3α-one) and 5α-androst-16-en-3α-one It is known as the main reason. In addition, it is known that isobaric acid produced by the action of microorganisms in secreted eczema sweat is the main cause of the jizo.

Generally, a deodorant for a human body refers to a product that removes or prevents body odor generated in the human body, such as a bad smell such as an underarm odor (odor), foot odor (foot), sweat odor, , Stick type, powder type, granule type, liquid type and gel type.

These deodorants are classified into the following four principle.

(1) Physical deodorization method: The odor is removed by ventilation or diffusion, or the odor is adsorbed by using a porous material such as activated carbon, zeolite or silica gel.

(2) Sensory deodorization method: A method of blocking offensive odor by a directional substance (perfume).

(3) Chemical deodorization method: A method in which a deodorant is chemically reacted with a malodor component to neutralize it by neutralization reaction, addition reaction, condensation reaction and oxidation reaction.

(4) Biological deodorization method: A method to fundamentally prevent the occurrence of odor, such as sterilization of bacteria or bacteria that cause odor, or prevention of decay.

The physical deodorization method of (1) above is one of the widely used deodorization methods, and is widely used as a residential deodorant other than the human body, but it is ineffective in terms of feeling when used in the human body. The sensory deodorization method of (2) is a method of blocking offensive odor by itself, but it is difficult to keep the balance between aroma and odor harmoniously, and since the sign of the odor of the deodorant varies depending on the individual, It is not suitable for use. In addition, the chemical deodorization method (3) can be effectively used for various odor components, but there is an inconvenience that it is necessary to pay attention to handling according to the used medicament. In addition, the biological deodorization method of (4) has not been able to obtain an expected effect after the odor has been generated. Thus, all of the four deodorization methods can not provide perfect deodorization and have been selected and applied according to the purpose of use.

In order to overcome the limited usability of such deodorants, various studies have been carried out on the main components thereof. For example, plant extracts are applied as deodorants. As a main prior art related thereto, Korean Patent Laid-Open Publication No. 2008-0089893 using an extract of a mixture of grapefruit, green tea and chitosan; Using at least one plant extract selected from the group consisting of non-leaf extracts, Puerariae Radix Extract, Ganoderma Lucidum Extract, Killer Extract, Irish Extract, Ginkgo Biloba Extract, Mulberry Extract, Licorice Extract, Sucrose Extract, 0043302; Korean Patent Laid-Open Publication No. 2005-0104884 using green tea extract and peony root extract; Korean Patent Laid-Open Publication No. 2001-007714 using wood vinegar is known. However, these prior arts have a disadvantage in that their effect is limited and unclear in actual body odor prevention.

It is an object of the present invention to provide a cosmetic composition having an excellent deodorizing effect on a human body.

In order to achieve the above object, the cosmetic composition for reducing body odor of the present invention is characterized by containing triclosan, bamboo salt and tocopherol acetate.

The total content of triclosan acid, bamboo salt and tocopherol acetate in the composition of the present invention is preferably 0.01 to 20% by weight based on the total weight of the composition.

The content of each of triclosan acid, bamboo salt and tocopherol acetate is preferably 0.001 to 10% by weight based on the total weight of the composition.

The formulations of the compositions of the present invention may also be formulated as soaps, bodywashes, handwashes, aerosols, sticks, roll-ons, pumps, sheets, patches, creams, lotions, gels or powders.

In the present invention, it has been found that the combination of triclosan, bamboo salt, and tocopherol acetate shows excellent deodorizing effect compared with the combination of the components alone or in combination of two.

Triclosan, which is used as a main ingredient, is a raw material for cosmetics widely used in various sanitary products and cosmetics due to its strong antibacterial and sterilizing effect. Bamboo salt is also known to be used for oral hygiene products such as toothpaste due to its excellent sterilization effect. Acetic acid tocopherol is a raw material mainly used in cosmetics for the purpose of inhibiting acidosis of fatty acids and oils and improving prescription stability due to its excellent antioxidative effect . The content of these triclosan acid, bamboo salt and tocopherol acetate in the composition of the present invention may vary somewhat depending on the formulation, but is preferably 0.01 to 20% by weight based on the total weight of the composition. When the content is less than 0.01% by weight, it is difficult to obtain a deodorizing effect as expected. When the content is more than 20% by weight, stabilization of the formulation is difficult and odor of the raw material itself may become a problem.

The cosmetic composition of the present invention can be used as a general cosmetic formulation in the form of an aerosol, a stick, a roll-on, a pump, a sheet, or the like as well as a human body detergent such as a soap, body wash, It can be formulated into a sheet, a patch, a cream, a lotion, a gel, a powder, and the like. Of these, aerosol or pump type is the most widely used formulation because it is easy to use and has excellent feeling.

The cosmetic composition according to the present invention containing both triclosan acid, bamboo salt and tocopherol acetate has superior deodorizing effect as compared with the case of containing only one or two components, and the sum of these components is 0.01 to 20 wt% %, There is an effect that the deodorizing action and the workability are excellent.

Hereinafter, the present invention will be described in more detail with reference to examples and comparative examples. However, these examples are merely examples of the present invention, and the scope of the present invention is not limited thereto.

Example  1 and Comparative Example  2 to 7

Triclosan, Bamboo Salt and Tocopheryl Acetate were used to measure the deodorizing effect according to the following method, and the results are shown in Table 1 below.

(1) indicator substance

Among the causative substances of body odor identified to date, isovaleric acid (Isovaleric acid, Aldrich, USA), which is a representative substance of the body odor, and 5-androst- 16-en-3-one, Aldrich, USA) were compared with each other by gas detection method and sensory evaluation method.

(2) Gas detection method

Add the appropriate amount of deodorization test substance (ml or g) and 1 ml of isovaleric acid (1% dilution of ethanol) into a flask, insert a gas detection tube (No. 81L, GASTEC, Japan), seal it completely, GV-100S, GASTEC, Japan) for 1 minute, and the degree of change of the coloring reagent in the detection tube was read in units of PPM.

(3) Sensory test method

3 ml of 5-alpha-androst-16-ene-3-one (diluted with 1% ethanol) was added to the flask, and 30 minutes after sealing, the three sensory evaluation specialists The smell was assessed according to the following criteria, and the average value was obtained.

- Evaluation criteria of sensory test method -

The deodorant effect on the human body odor was evaluated by the following method for the manufactured body washes.

Deodorant  Effect evaluation method

The test subjects were grouped into nine groups of 20 persons per group. Only the bodywashes of Comparative Example 8 were used in the left armpit (control group) for one week and those of Examples 2 to 5 (groups 1-4) were used in the right armpit ) And Comparative Examples 9 to 15 (Groups 5 to 11). For bodywashing, each body wash is rubbed on a clean cloth damped with water for 15 seconds, rinsed with a cloth impregnated with body wash for 30 seconds, then rinsed with a dry towel. On the last day of the 7th day, a clean dry dress shirt was put on and after 5 hours, the body odor (liquor) strength was evaluated with a score of 0 to 5 according to the degree of smell. Three evaluators were participated in this study. The results were summarized as the results of the deodorizing effect.

Table 3 below shows the results of evaluating the deodorizing effect of the bodywashes prepared in Examples 2 to 5 and Comparative Examples 9 to 15.

- Body odor (odor) evaluation criteria -

Score 0: No odor (odor) at all.

Score 1: Body odor (odor) can be felt very slightly.

Score 2: I can feel the odor (smell) clearly, but it is weak.

Score 3: Body odor is normal.

Score 4: Body odor felt strongly.

Score 5: Body odor felt very strongly.

The percent deodorization (%) is obtained as follows:

Deodorization rate (%) = {(control value - test group determination value) / (control value)} 100

As shown in Table 3 above, the deodorizing effect of body washes containing both triclosan acid, bamboo salt and tocopherol acetate was superior to the case of containing only one or two of them. In the case of Comparative Example 14 in which the sum of the amounts of triclosan acid, bamboo salt and tocopherol acetate was less than 0.01% by weight of the total composition, the deodorizing effect was lower than expected. In Comparative Example 15 exceeding 20% by weight, But there was a difficulty in manufacturing. From these results, it can be seen that the formulations such as body wash according to the present invention are excellent in deodorizing effect and workability when the content of triclosan acid, bamboo salt and tocopherol acetate is in the range of 0.01 to 20% by weight.
