Description

Composition for removing undesired molecular < RTI ID = 0.0 >

The present invention relates to compositions capable of removing unwanted molecules and also capable of delivering perfume materials.

There are many applications such as laundry detergent, fabric softener, surface cleaner, kitchen detergent, deodorant, shampoo, hair conditioner, human body and undergrowth remover in many demands of removing odor in clothing, residential space and limited indoor space The aim of the study was to achieve the above objectives. In many studies, cyclodextrins have been applied (US Pat. No. 6,878,695) as an example of an effective removal material. The cyclodextrin is a cyclic cyclic polysaccharide in which 6 to 12 glucose are linked by alpha-1,4 bond. As one example of the most developed cyclodextrins, alpha-cyclodextrin includes 6 glucose. In another example, beta-cyclodextrin contains 7 glucose, and gamma-cyclodextrin includes 8 glucose , All of which have donut-shaped ring structures.

Certain bonds or structures between glucose allow the cyclodextrin to have a rigid, conical structure with a certain volume of void space. The "arrangement" of each internal space is formed by an oxygen atom that is bridged with a hydrogen atom. Therefore, the inner surface is very hydrophobic and the specific shape and physico-chemical properties of the interior have structural features that can absorb organic molecules or portions of organic molecules that match the shape of the inner space of cyclodextrin or its derivatives. Therefore, when a preparation containing cyclodextrin is applied to the surface of an object, it is possible to remove impurities by inclusion of foreign substances such as foreign matter into the inner space of the cyclodextrin. In addition, some of the products may be impregnated during the manufacturing process so that the fragrance is continuously diffused during use.

However, these cyclodextrins have a disadvantage in that the size of the internal space is constant and the fragrant materials and odorous substances that can be capsulated are limited, and when the preparation contains a water-soluble solvent such as water, the cyclodextrin has poor efficacy There is a limitation in expression. Particularly, perfume materials having clopP of not less than 3 and bp of not less than 250, which are generally known to have excellent reverberation and good odor masking, have a problem in that sufficient removal of the offensive substances by the cyclic dextrin and transmission of perfume materials are limited. Cyclodextrins have low solubility and have been developed to overcome them. Examples of cyclodextrins include those in which some OH groups are substituted with OR groups, or R is a methyl or ethyl group, -CH ₂ -CH (OH) -CH ₃ or a -CH ₂ CH ₂ -OH group, or a cationic cyclodextrin which is cationic at pH.

The present invention relates to a substance capable of complementing the above-mentioned problems of cyclodextrins conventionally used for the removal of undesired molecules, more specifically, the removal of odor, and the inclusion of a wider variety of fragrance materials and odoriferous substances.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to overcome the above-mentioned disadvantages by applying cyclic dextrin having an inner space of a larger size and various sizes to remove various undesired molecules that could not be encapsulated in conventional cyclodextrin, But also to be able to capture more hydrophobic and molecular weight fragrance materials that could not be captured in cyclodextrin.

It is another object of the present invention to provide a method and a device for separating deodorant by applying a cyclic dextrin having an inner space of a wider size and various sizes to a perfume material enclosed in an inner space of cyclic dextrin, And fragrance, and to provide a method for the same.

The inventors of the present invention have found that cyclodextrin used for removing odor is limited in its internal space and shape, and thus has a limited off-flavor source or perfume. To improve the cyclodextrin, a cyclodextrin such as cyclodextrin A dextran with a highly branched cyclic structure was designed to have various internal spaces. It has been confirmed that dextrin having such a highly branched cyclic structure has a remarkably improved ability to remove odor as compared with the cyclodextrin used in the past, and that the cyclodextrin can not encapsulate a large molecular weight and hydrophobic fragrance material, The present invention has been accomplished in anticipation of having improved ability.

An undesired molecule in the present invention means an odor source having an undesired fragrance as an organic directional molecule. These odor sources can be present on the surface of fabrics such as carpets and on household surfaces such as kitchen countertops, dishes, floors, trash cans, ceilings, walls, carpets, air purifying filters and the like and skin, hair and the like, It is possible to remove a molecule, that is, a foreign matter. For example, when a material such as (E) -5-methyl-2-hexenoic acid, 5-methyl-4-hexenoic acid, 6-heptenoic acid, isovaleric acid, 4-methylhexenoic acid, (Flavor and Fragrance Journal, 2012, vol.27, 89-94) and various studies on the odoriferous components derived from the human body have been conducted (Anti-Aging Medicine, 2010, 7 6): 60-65). Therefore, in the present invention, the odor source refers to a common odor component that can occur in everyday life, such as a normal human body origin or a textile origin, and is not limited to the above example.

These compositions may be transparent, translucent, opaque depending on the type and concentration of the materials in the composition.

The composition of the present invention should be a composition capable of effectively delivering high site cyclic dextrin or derivatives thereof, and is not limited to this formulation.

Hereinafter, the components of the undesired composition for removing molecules will be described in more detail.

1) Highly branched Cyclic Dextrin (HBCD)

Cyclodextrins and derivatives thereof have been used in compositions for removing unwanted substances. Cyclodextrins contain 6-8 glucose, and they have a donut-shaped ring structure. Such cyclodextrins allow a specific binding or structure between glucose to have a tight conical structure in which the cyclodextrin has a specific volume of void space. The arrangement of each internal space is formed by an oxygen atom having a hydrogen atom and a glycoside bridge. Therefore, the inner surface becomes very hydrophobic, and the specific shape and physico-chemical properties of the inner part absorb the organic molecules or organic molecules whose cyclodextrin and its derivatives are in conformity with space and shape, and it is possible to remove the foreign substances. Also, there was a mechanism in which fragrance giving fresh impression was located in the inside specific shape, and the fragrance was replaced with cyclodextrin when odor was present.

The present invention attempts to overcome the limitations of cyclodextrin by applying cyclic dextrin having a wider and more diverse inner space than a single spatial structure like the cyclodextrin.

The cyclic dextrin used in the present invention is a highly branched cyclic dextrin. The highly branched cyclic dextrin refers to a cyclic dextrin having a high degree of branching via an alpha-1,6 bond in a linear chain such as amylopectin, Of the chain of the polymer polysaccharide is broken, and the broken link means a chemical structure having a ring chain by using a branching enzyme. For example, it is formed through a method as schematically shown in FIG. 1 .

More specifically, the highly branched cyclic dextrin used in the present invention may be represented by (C ₆ H ₁₀ O ₅ ) xH ₂ O and may be an odorless white powder of oligosaccharide having alpha-di-glucose as a monomer (g / mol). The average molecular weight is about 30,000 to 1,000,000, and the degree of polymerization is preferably 2,500 glucose units. Also, the equivalent value (dextrose equivalent (DE) value), that is, the reducing power of di-glucose is preferably 5 or less. In addition, preferably, a linear chain composed of alpha -1,4 bonds is linked with an alpha-1,6-glucosidic bond on the side chain of 16 to 100 di-glucose . This coupled structure allows the highly branched cyclic dextrin to have a cyclic alpha-glucan moiety.

When the highly branched cyclic dextrin according to the present invention has the above-mentioned conditions such as the average molecular weight, the equivalent value and the number of side chains of di-glucose, it is preferable that the cyclic dextrin The collection ability becomes more suitable.

The term "highly branched cyclic dextrin derivative" refers to a cyclic dextrin derivative having a structure that maintains the basic structure so as to obtain all functions according to the present invention according to the structural characteristics of the highly branched cyclic dextrin of the present invention, Quot; means a structure in which an atom or an atomic group of the moiety is substituted.

Thus, the use of a highly branched branched cyclic dextrin having a high branching point in the composition according to the present invention improves the ability of the present composition to bind to undesired molecules on the surface treated with the composition, and even at lower concentrations of cyclodextrin derivatives It is possible to more effectively reduce or eliminate non-existent molecules.

More specifically, the structural features of the highly branched cyclic dextrin according to the present invention are such that it can absorb various organic molecules or portions of organic molecules conforming to at least one internal space and shape of the highly branched cyclic dextrin (So as to form a polymer), so that many foreign substances on the surface of the object, including unwanted organic molecules including odor molecules, etc., can be accepted into the interior space. Therefore, the highly branched branched cyclic dextrin according to the present invention having various sizes of interior can remove odors generated by a wide range of organic aromatic molecules having various active groups, as well as excellent reverberation, good odor masking a variety of perfume materials having a clogP of 3 or more and a boiling point of 250 degrees or more can be usefully delivered.

In order to functionally function the hyperbranched cyclic dextrin within the composition, at least about 0.1% to about 20%, preferably about 0.5% to about 10%, more preferably about 1% 5% by weight. When the content is included, it can be said that it is effective not only to remove odor but also to transfer fragrance components.

2) Spices

The fragrances according to the present invention are contained in at least one cyclic structure of the above-mentioned highly branched cyclic dextrin to form a stable composition. The stable composition of the present invention provides an emotional quality of a good fragrance, which, when treated on the surface of fabrics, human bodies, etc., removes foreign matter, i.e. odor, to give a fresh impression. In the present invention, the perfume can provide at least a sustained flavor.

The fragrances which can be contained in the highly branched cyclic dextrin according to the present invention are characterized in that they can encapsulate various fragrances regardless of their hydrophilic and hydrophobic fragrances. This is because the highly branched cyclic dextrin according to the present invention is a cyclodextrin It can be seen that not only the fragrance that can be grafted but also the fragrance which could not be captured from cyclodextrin can be grafted, it is possible to capture various fragrance. That is, the fragrance encapsulated in the highly molecular cyclic structure dextrin according to the present invention is not limited to a specific fragrance, and is characterized by being capable of containing various perfumes.

On the other hand, the incense ratio of the fragrance is a ratio to the alcohol relative to the perfume stock solution, and the incidence rate of the fragrance according to the present invention is about 0% to about 3%, preferably about 0.003% to about 2% Is about 0.005% to about 1%.

The present invention adds fragrance to eliminate odor and keep odor on the surface longer. When strong fragrance is required, it is possible to apply fragrance with a high fragrance ratio or to apply a fragrance with excellent reverberation. Any type of perfume can be applied to the composition of the present invention, and the perfume ingredients can be both hydrophobic and hydrophilic.

In order to sustain the fragrance longer, the fragrance should have at least a partial hydrophobicity and a relatively high boiling point. That is, fragrance mainly consists of fragrance materials belonging to the following two groups. (a) a hydrophobic component of ClogP 3 or higher, preferably 3.5 or higher, (b) a perfume ingredient having a molecular weight of 205 or higher, preferably 210 or higher, more preferably 220 or higher.

Since the properties of the perfume ingredients are various and are influential on the substances present in the surroundings, it is not easy to clearly distinguish the physical characteristics such as ClogP and molecular weight. Therefore, the above-described numerical value is a rough value for expressing the property of the perfume, and should be interpreted flexibly in the numerical range analysis.

For these hydrophobic flavors, the weight ratio of perfume to highly branched cyclic dextrin is from about 2: 1 to about 200: 1; Preferably from about 4: 1 to about 100: 1, more preferably from about 6: 1 to about 50: 1, even more preferably from about 8: 1 to about 30: 1.

The hydrophobic fragrance has a property of strongly binding to cyclic dextrin. The hydrophobicity of the perfume ingredient is related to the octanol / water partition coefficient, P, of the ingredient. The octanol / water partition coefficient of the perfume is the ratio of the equilibrium concentration of octanol to the perfume in water. The higher the partition coefficient P, the more hydrophobic the fragrance has, and the lower the partition coefficient P, the more hydrophilic. Because fractions of fragrances are generally high, logs with a bottom 10 can be conveniently displayed in the form of logP. Other fragrances in the present invention therefore have a logP value of at least about 3, preferably at least about 3.1, and most preferably at least about 3.2.

In addition, the hydrophobic perfume composition includes at least about 5% to 80% by weight, preferably about 10% to 60% by weight, more preferably about 15% to 40% by weight of the total perfume composition.

More specifically, the highly branched cyclic dextrin according to the present invention may be used as a flavor which is not encapsulated with cyclodextrin, such as Galxolide, Eso-E super, Helvetolide, At least one perfume may also be included in the group consisting of CI, CI, CI, CI, These perfumes are excellent in odor masking ability, excellent in preference for fragrance, and can increase the persistence of fragrance more easily as a high molecular weight and hydrophobic fragrance.

Table 1 below shows the feasibility of combining several reverberant cyclodextrins and highly branched cyclic dextrins according to the present invention. The highly branched cyclic dextrin according to the present invention has a wider variety of internal spaces than the cyclodextrin, and thus it is possible to encapsulate a fragrance having a large molecular weight which can not enter the cyclodextrin. Thus, it is possible to apply more fragrances using the highly branched cyclic dextrin according to the present invention, so that the fragrance spectrum of the composition can be widened and the persistence of the reverberation can be increased.

The fragrance formulations for the present invention generally comprise at least 4, preferably 5, more preferably 6, even more preferably 7 hydrophobic reverberating fragrances. The most widely used natural fragrances are also composed of many components.

In addition, the hydrophilic fragrance is characterized in that it easily escapes from the highly branched cyclic dextrin within the aqueous composition, and this hydrophilic flavor mainly consists of components having ClogP of about 3.5, preferably about 3.0 or less.

If the perfume ingredients are hydrophilic, they dissolve in a water-soluble composition and are not highly bound to cyclic dextrin. In order to maintain the function of cyclic dextrins which reduce / eliminate foreign substances such as odor, the hydrophilic flavor is preferably present in a weight ratio of not more than about 90% by weight, preferably not more than 50% by weight, 30 wt% or less, and most preferably 10 wt% or less. The ratio of cyclic dextrin to such hydrophilic flavor should be at least about 8: 1, preferably at least about 10: 1, more preferably at least about 20: 1 and most preferably at least about 70: 1.

In addition, in the present composition, the perfume may be present in an amount of 0.1 to 10.0% by weight, preferably 0.5 to 5.0% by weight, based on the total weight of the composition, The improvement can be maximized.

3) Solvent

In the present invention, the solvent means a transporter, and water is preferably used, and distilled water or water from which ions have been removed, tap water can also be used. Water not only functions as a transporter of highly branched cyclic dextrin but also promotes the bonding of highly branched cyclic dextrin with foreign substances such as off-gas molecules on the treated surface. It is also known that the treatment of an aqueous solution on a surface contaminated with odor generated by organic amines, acids, mercaptans, etc. having a polarity and a small molecular weight decreases the strength. It is considered that the water used as a solvent in the present invention solubilizes polar and low molecular weight non-ionic molecules and reduces the vapor pressure to lower the strength of the off-odor.

The concentration of the solvent, i.e. water, used in the composition of the present invention may vary depending on the use of the composition. The composition for manual or automatic spraying is such that the weight of water relative to the weight of the total composition is from about 30 wt% to about 99.9 wt%, preferably from about 50 wt% to about 99.9 wt%, more preferably from about 60 wt% About 95% by weight.

In addition, in the composition for removing the odor of the fabric, alcohol may be used as a solvent, and the weight of the alcohol relative to the weight of the total composition is about 20% by weight or less, preferably about 10% or less, more preferably about 5% Concentration.

The dilution of the aqueous solution widens the application range of the highly branched cyclic dextrin on the fabric and maximizes the opportunity for the highly branched cyclic dextrin molecules and the odor molecules to combine.

4) Surfactants

In the present invention, the surfactant may be further included in the composition of the present invention in order to appropriately reduce or eliminate foreign substances on the surface of the object or to make the fragrance component smell for a long time. For the proper removal of odor, the surfactant comprises a stable surfactant capable of easily bonding with the highly branched cyclic dextrin according to the present invention, and further comprises a surfactant which is not easily encapsulated in the highly branched cyclic dextrin according to the present invention It is important that the properties of polymers and polymers, which generate low surface tension, spread more easily and evenly on hydrophobic surfaces such as fabrics.

Surfactants used in the present invention may generally include those used in detergents, fabric softeners, shampoos, surface cleaners, cosmetics, personal care products, mouthwashes, bodywashes, shaving products, skin moisturizer compositions and the like.

Using a composition containing a highly branched cyclic dextrin-stabilized surfactant will dry faster depending on the type and characteristics of the surfactant applied, thereby removing the foreign matter on the treated object more quickly. Among the components of some compositions, fragrances which are encapsulated in highly branched cyclic dextrins and are not easily dissociated are used to promote the formation of highly branched cyclic dextrins and surfactants and micelles or vesicles, Contributes to strengthening the merit of long reverberation.

The binding force between the surfactant and the highly branched cyclic dextrin according to the present invention can be confirmed by confirming the change in the interfacial tension (dyne / cm) depending on the presence or absence of highly branched cyclic dextrin in the surfactant aqueous solution. The surfactant aqueous solution comprises a surfactant at a concentration of about 0.5%, about 0.1%, about 0.01%, about 0.005%, and a surfactant at a given concentration of surfactant in the same concentration as the surfactant solution at a given concentration, If the increase in interfacial tension of an aqueous solution further containing highly branched cyclic dextrin is greater than about 10%, this means that there is a strong bond between the surfactant and the cyclic dextrin.

Preferred surfactants for the composition according to the present invention are those in which the change in interfacial tension does not bind the surfactant weakly with the cyclic dextrin (the interfacial tension increases to less than about 5%) in the present invention (interfacial tension Less than about 1%).

Typical surfactant concentrations in the composition according to the present invention are between about 0.01% and about 2% by weight, preferably between about 0.03% and about 0.6% by weight, more preferably between about 0.05% To about 0.3% by weight. The concentration of the surfactant in the concentrated surfactant composition is generally between about 0.1 wt.% And about 20 wt.%, Preferably between about 0.2 wt.% And about 15 wt.%, More preferably between about 0.3 wt.% And about 10 wt.%, , But is not limited thereto.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a schematic view showing a process of forming highly branched cyclic dextrin according to the present invention. FIG.

Hereinafter, embodiments of the present invention will be described in detail to facilitate understanding of the present invention. However, the embodiments according to the present invention can be modified into various other forms, and the scope of the present invention should not be construed as being limited to the following embodiments. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art.

<Examples>

Since the composition according to the present invention is composed of highly branched cyclic dextrin, fragrance and solvent, it is important that the function of the highly branched cyclic dextrin is present in the composition during the production of the composition. In order to keep the highly branched cyclic dextrin having the function in the composition, it must first be mixed with the highly branched cyclic dextrin and the surfactant. As a result, after a molecular polymer such as a micelle or a vesicle is formed, impurities such as perfume are impregnated into the highly branched branched cyclic dextrin-surfactant molecule polymer, thereby effectively separating the highly branched cyclic dextrin from the inner space and functioning in the composition The composition can be maintained.

In the present invention, in order to remove the odor of fabrics, in particular dry fabrics, compositions were prepared in spray form and evaluated for application. However, the efficacy of the present invention is not limited to this formulation. It is preferable to use a composition in which a low concentration of highly branched cyclic dextrin is applied so as not to leave stains on the fabric in a general usage amount such as a spray type formulation used for removing odor of a fabric, Should be invisible after drying.

In general use conditions, the total highly branched branched cyclic dextrin in the composition is usually from about 0.01% to 5% by weight, preferably from about 0.1% to 4% by weight, more preferably from about 0.5% to 2% by weight . In order to exhibit the function of the highly branched cyclic dextrin in the composition, it is preferable that it contains at least about 0.001 wt% to 0.1 wt%. Compositions with high concentrations can leave visible stains on the fabric as it is dried, and can be a problem especially in thin and colored synthetic fabrics.

3. Evaluation of odor intensity

The evaluation of the odor removing effect on the compositions of the comparative examples and the examples was carried out as follows.

1) The fabric to be evaluated is washed with a washing machine using an untreated detergent cotton towel 30cm x 30cm and dried with a dryer.

2) Apply approximately 80 microliters of the odorless prescription to the dried cotton towel to an area of 5 cm x 5 cm on each fabric, seal it in a plastic bag, and leave overnight at room temperature.

3) The trained evaluators evaluate the initial strength of the fabric to which it is applied and score it according to the following rating scale.

4) Then apply the same amount of the prescriptions to be evaluated to the fabric and dry for 30 seconds.

5) If the fabric dries, the odor intensity of the fabric applied by the evaluators is scored according to the following evaluation scale.

6) Record the first score and the last score, and calculate the odor reduction value with the difference of the scores.

The evaluators performed a preliminary training for a clear recognition of the standard odor by 8 persons. The evaluation was carried out by one person in a single evaluation booth equipped with forced ventilation facilities and the evaluation was limited to three or more at a time to improve the accuracy of the evaluation.

Table 4 below shows the evaluation standards for odor.

score Evaluation contents 0 point No odor 1 point There is a weak odor. 2 points There is a moderate odor. 3 points There is a slight strong odor. 4 points There is strong odor. 5 points Very strong odor.

After 10 minutes and 30 minutes, the intensity of the fragrance was evaluated to evaluate the reverberation increase effect of cyclic dextrin.

Table 5 below is a reverberation evaluation standard.

score Evaluation contents 0 point The scent is not felt at all. 1 point Weak fragrance. 2 points Medium fragrance. 3 points Slightly strong fragrance. 4 points Strong fragrance. 5 points Very strong fragrance.

4. Evaluation results

Approximately 80 microliters of the odorant prescription was applied to each fabric in an area of 5 cm x 5 cm, sealed in a plastic bag and allowed to stand at room temperature overnight. Then, on the surface towel of 30 cm x 30 cm, The evaluation result was 4.2 points.

Table 6 shows the difference between the evaluation result and the evaluation result of the odor source after drying for 30 seconds after the application of Comparative Example 1 and Experimental Examples 1 to 7.

It was found that the deodorizing effect was better than in Examples 1 to 7 in which cyclodextrin was used as a deodorizing agent in comparison with Comparative Example 1 in which cyclodextrin was used. Comparing Comparative Example 1 with Example 1, there is a difference in the deodorizer system, and in Example 1 and Example 2, the content of the deodorizer system is the same and there are differences in kinds. It can be seen that cyclic dextrin is superior to cyclodextrin in removing odor when the odor eliminating base is the same amount.

Also, in the case of Example 2 and Example 3, it was confirmed that when Copolymer 958, which is a cyclic dextrin-compatible polymer, was applied, the effect of removing deodorant by cyclic dextrin was increased. It was found that Example 4 having a higher content was more excellent when the contents of fragrances were varied to 0.10% and 0.06% in the comparison of Example 4 and Example 5, respectively. Further, when the application of the amphoteric surfactant Velvetex BK-35 was compared with the other Example 2 and Example 4, the result of Example 4 using the Velvetex BK-35 applied was superior. Compared with Example 6 and Example 7, it was confirmed that the addition of an amphoteric surfactant and a cyclic dextrin compatible polymer capable of providing a synergistic effect to removal of the deodorant of cyclic dextrin increased the deodorization effect there was.

The results of evaluating the reverberation strength after 10 minutes and 30 minutes are shown in Table 7. Compared with Comparative Example 1 and Examples 1 to 7, the reverberation property was found to be different after 30 minutes, rather than after 10 minutes. It can be judged that the cyclodextrin rather than the cyclodextrin is more abundant in fragrance components having ClogP 3.0 or higher and boiling point higher than 250 ° C, and releasing over time.

Also, as the content of cyclic dextrin increased, the difference between the reverberation after 10 minutes and the reverberation after 30 minutes was small. Comparing Example 6 with Example 7, it was confirmed that the effect of increasing the reverberation of cyclic dextrin was further enhanced by adding polymers and amphoteric surfactants capable of increasing the mutual adhesion between the fragrance and the fibers.
