Description

  The present invention relates to a composition capable of removing unwanted molecules and delivering a perfume material.

  This application includes Korean Patent Application No. 10-2014-0050740 filed on April 28, 2014, Korean Patent Application No. 10-2014-0087656 filed on July 11, 2014, and January 7, 2015 application. All contents disclosed in the specification and drawings of the corresponding application claiming priority based on Korean Patent Application No. 10-2015-0002127 are incorporated in this application.

  There are various sources of malodors that occur in general living spaces. Many offensive odors are mainly a combination of various components such as sulfur or nitrogen. Methods for removing such malodors include physical methods, chemical methods, biological methods or sensory methods. The physical method means a method using adsorption by a porous substance such as activated carbon, silica gel, zeolite, alumina or ceramics or absorption by a surfactant. Chemical methods use neutralization reactions, condensation reactions, addition reactions, oxidation or reduction reactions, etc. to deodorize substances that react with malodorous components or react with malodorous components to form complexes. It is a method of eliminating odors by using it as an agent. The biological method refers to a method of sterilizing bacteria or bacteria that cause bad odor by using a surfactant, ethylene glycol, microorganisms or enzymes, or deodorizing them by preventing spoilage. The sensory deodorization method refers to a method of replacing or neutralizing malodorous stimulation with an aromatic substance such as a fragrance. In addition to such methods, various techniques for removing malodors are known, but the technique capable of continuously removing malodors is still insufficient.

  In response to many demands for removing off-flavors present in clothing, residential spaces, limited indoor spaces, etc., companies in laundry detergents, softeners, surface cleaners, kitchen detergents, deodorants, shampoos, hair conditioners, body products, The above-mentioned purpose has been achieved through various application studies on deodorants for sideways. As an example of an effective removal substance in many studies, there is a case (US 6,878,695) in which cyclodextrin is applied. The cyclodextrin is a polysaccharide having a cyclic structure in which 6 to 12 glucoses are linked by α-1,4 bonds. As an example of the most developed and applied cyclodextrin, α-cyclodextrin contains 6 glucoses, as another example, β-cyclodextrin contains 7 glucoses, and as another example, γ-cyclodextrin contains 8 glucoses. Containing one glucose, all of which have a donut-shaped ring structure.

  The specific bonds and structures between glucose make the cyclodextrin have a rigid conical structure with a specific volume of space. The “array” of each internal space is formed by oxygen atoms that form glycoside bridges with hydrogen atoms. Therefore, the inner surface has very high hydrophobicity, and the specific shape and physical / chemical properties of the inside are an organic molecule or a part of the organic molecule whose shape matches the internal space of cyclodextrin or its derivatives. Have structural features that can absorb Therefore, when a preparation containing cyclodextrin is applied to the surface of an object, foreign substances such as off-flavor can be removed by inclusion in the internal space of cyclodextrin. Further, by impregnating a part of the fragrance of the product during the production process, the fragrance can be continuously emitted during use.

However, such cyclodextrins have the disadvantage that the perfume and off-flavor substances that can be included are limited because the size of the internal space is constant, and the preparations contain water-soluble solvents such as water. When included, there is a limit to the expression of efficacy due to the poor solubility of cyclodextrins. In particular, a fragrance material having a ClogP of 3 or more and a boiling point of 250 ° C. or more, which is generally known to have excellent residual fragrance properties and good off-flavor masking effects, is sufficient for off-flavor materials by cyclodextrin. There is a problem that there is a limit to the removal and transmission of perfume materials. In addition, since cyclodextrin has low solubility, a derivative is being developed to overcome this, and in one example of cyclodextrin, a substance in which a part of OH groups is substituted with OR groups, or R Is substituted with a methyl or ethyl group, or is substituted with a hydropropyl group in which R is a —CH ₂ —CH (OH) —CH ₃ or —CH ₂ CH ₂ —OH group There are various types such as cationic cyclodextrins that are cationic at pH.

    The present invention relates to the removal of undesirable molecules, and more specifically, can compensate for the above-mentioned problems of cyclodextrins conventionally used for removing off-flavors, and can include a wider variety of perfume substances and off-flavor substances. Concerning substances.

 The present invention has been made in view of the above problems, and by applying a cyclic dextrin having a wider and varied internal space, it is more undesirable than the conventional cyclodextrin that could not be included. Not only is it easy to remove molecules, more specifically various off-flavors, but also to allow inclusion of more diverse, hydrophobic and high molecular weight perfume materials that could not be included in cyclodextrins. With the goal.

 In addition, the present invention applies a cyclic dextrin having an inner space of a wider and varied size, and releases a fragrance substance included in the inner space of the cyclic dextrin so as to include an odor source. It is another object to provide a composition that removes and transmits a scent and a method for developing the composition.

 Another object of the present invention is to provide a method for producing an undesirable molecular removal composition to which a highly branched cyclic dextrin is applied.

 To achieve the above object, the present invention provides a highly branched cyclic dextrin (HBCD) or a derivative thereof, a fragrance included in at least one internal space of the highly branched cyclic dextrin, and A composition for removing unwanted molecules, characterized in that it comprises a solvent.

  According to a preferred embodiment of the present invention, the highly branched cyclic dextrin is linked to D-glucose within 16 to 100 by α-1,6-glucoside bond. It can be in form.

  According to another preferable example of the present invention, the highly branched cyclic dextrin may have a dextrose equivalent value of 5 or less.

According to still another practical example of the present invention, the highly branched cyclic dextrin is an oligosaccharide having α-D-glucose as a monomer, and has a chemical formula (C ₆ H ₁₀ O ₅ ) × H _2. It may be a compound represented by O (x is an integer of 200 to 5,000).

  According to another embodiment of the present invention, the highly branched cyclic dextrin may have an average molecular weight of 30,000 to 1,000,000 g / mol.

  According to still another embodiment of the present invention, the highly branched cyclic dextrin may include 0.01 to 20% by weight based on the total weight of the composition.

  According to still another preferred embodiment of the present invention, the solvent may include water.

  According to still another preferred embodiment of the present invention, the composition may further include a surfactant.

  According to still another preferred embodiment of the present invention, the composition may further include a water-soluble polymer.

  According to still another preferred embodiment of the present invention, the composition may further include a plant extract.

  The composition for removing undesired molecules according to the present invention is an undesired molecule that could not be included by cyclodextrin, more specifically, by applying a cyclic dextrin having a wider and varied internal space. In addition to easy removal of various off-flavors, it is possible to include more diverse fragrance substances that cannot be included with cyclodextrin, are hydrophobic, and have a high molecular weight. With such a composition, the perfume substance in the highly branched cyclic dextrin is replaced with an off-flavor source, and has a high masking ability and a highly preferred scent, while removing foreign substances such as undesirable molecules such as off-flavor sources. Is possible.

  In addition, the composition for removing undesirable molecules according to the present invention further includes a plant extract, thereby producing a synergy effect in removing off-flavors.

The following drawings attached to the specification illustrate preferred embodiments of the present invention, and together with the detailed description, serve to further understand the technical idea of the present invention. It should not be construed as being limited to the matters described in the drawings.
FIG. 4 is a schematic diagram schematically illustrating the formation process of a highly branched cyclic dextrin according to the present invention.

  Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Prior to this, the terms and words used in this specification and claims should not be construed to be limited to ordinary or lexicographic meanings, and the inventor himself should explain the invention in the best possible manner. It must be interpreted with the meaning and concept corresponding to the technical idea of the present invention in accordance with the principle that the term concept can be appropriately defined. Therefore, the configuration described in the embodiments and drawings described in this specification is only the most preferable embodiment of the present invention, and does not represent all of the technical idea of the present invention. It should be understood that there are various equivalents and variations that can be substituted at the time of filing.

  The present invention is characterized by comprising a highly branched cyclic dextrin (HBCD) or a derivative thereof, a flavor and a solvent included in at least one internal space of the highly branched cyclic dextrin. The present invention relates to a composition for removing unwanted molecules.

  In order to improve this point, the present invention recognizes that the cyclodextrin used for removing off-flavor is limited in internal space and shape, so that the off-flavor source or fragrance included is limited. We have devised highly branched cyclic structure dextrins with wider and various internal spaces rather than single-structured spaces like cyclodextrins. Such highly branched cyclic dextrin not only has a significantly improved off-flavor removal ability compared with conventional cyclodextrins, but also has a high molecular weight and hydrophobic perfume substance that cyclodextrin could not contain. It was confirmed that it was possible, and the present invention was completed in anticipation of having an improved ability to remove off-flavors.

  As a result, the inventors of the present invention have a synergistic effect in removing off-flavors when a specific plant extract is included together with a highly branched cyclic dextrin, compared with a case where each includes a highly branched cyclic dextrin or a plant extract alone. As a result, the present inventors have found the surprising fact that it is improved.

  In the present invention, the undesired molecule means an organic fragrance molecule and a source of off-flavor having an undesired odor. Such off-flavors can be present on the surface of textiles such as carpets and kitchen utensils, dishes, floors, trash cans, ceilings, walls, household items such as air purification filters, and surfaces such as skin and hair. In addition, according to the present invention, such an undesirable molecule, that is, a source of off-flavor can be removed. Such off-flavor sources include, for example, substances such as (E) -5-methyl-2-hexenoic acid, 5-methyl-4-hexenoic acid, 6-heptenoic acid, isovaric acid, 4-methylhexenoic acid, or ethylocanoic acid. Is known as an off-flavor component that can occur in textiles (Flavor and Fragrance Journal, 2012, vol. 27, 89-94), and various studies on the off-flavor component derived from the human body are also progressing (Anti-Aging Medicine). 2010, 7 (6): 60-65). From this, the off-flavor source in the present invention means a normal off-flavor component that can be generated in daily life such as a normal human body or a fabric, but is not limited to this example.

  The composition can exist as an emulsion / dispersoid or as a clear, single-sided solution.

  In order to remove the off-flavor of the fabric or human body, the composition of the present invention is preferably a transparent single-sided solution, transparent or translucent, and preferably has a transparent property such as water.

  Also, when the composition of the present invention is used as a detergent, softening agent, shampoo, surface cleaner, an emulsion / dispersion is desirable, generally a size of about 0.05 μm or more, preferably about 0.1 μm or more, and more Desirably, it can have an assembly of micelles or vesicle molecules of about 0.2 μm or more. Such a composition may exist transparent, translucent, or opaque depending on the type and concentration of the substance in the composition.

  The composition of the present invention must be a composition capable of effectively delivering highly branched cyclic structure dextrin or a derivative thereof, but is not limited to the above-mentioned dosage forms.

  Hereinafter, the components of the composition for removing undesirable molecules will be described more specifically.

  1) Highly branched cyclic dextrin (HBCD)

  Usually, cyclodextrins and their derivatives have been used in compositions for removing undesirable substances. Cyclodextrins contain 6-8 glucoses, which have a donut-shaped ring structure. Such a specific bond or structure between glucose in the cyclodextrin allows the cyclodextrin to have a rigid conical structure with a specific volume of space. The arrangement of each internal space is formed by oxygen atoms that form glycoside bridges with hydrogen atoms. Therefore, the inner surface has very high hydrophobicity, and the specific shape and physical / chemical properties of the inside are an organic molecule or a part of the organic molecule whose shape matches the internal space of cyclodextrin or its derivatives. It was possible to remove off-flavor substances by absorbing the odor. In addition, Kiyoka's fragrance is located in such a specific shape inside, and when there is a strange odor, the fragrance is substituted and included in the cyclodextrin.

  The present invention attempts to compensate for the limitations of cyclodextrin by applying a cyclic dextrin having an internal space with a wider variety of sizes rather than a single spatial structure like the cyclodextrin.

  The cyclic dextrin applied to the present invention is a highly branched cyclic dextrin, and the highly branched cyclic dextrin is highly branched by α-1,6 bonds in a linear chain like amylopectin. This is a chemical structure in which the polymer polysaccharide chain of glucose possessed is broken, and such a broken linkage has a cyclic chain using a branching enzyme. In one example, FIG. It is formed by a method as schematically shown.

More specifically, highly branched cyclic dextrin used in the present _{invention, (C 6 H 10 O 5} ) xH 2 O (x is an integer of 200 to 5,000.) Can be represented by, Oligosaccharide, which is an odorless white powder using α-D-glucose as a monomer, and has an average molecular weight of about 30,000 to 1,000,000 per mole (g / mol), Desirably about 100,000 to 900,000, more desirably about 200,000 to 800,000, even more desirably about 300,000 to 700,000, and most desirably about 400,000 to 600,000. . When the average molecular weight is less than 30,000 g / mol, the internal space is narrow, so that the inclusion capacity of large malodorous components or various sizes of incense is inferior and exceeds 1,000,000 g / mol. , The dosage form stability and molecular stability of the composition are impaired. The degree of polymerization is 2500 glucose units. Moreover, the equivalent value (dextroequivalent (DE) value), ie, the reducing power of D-glucose, is desirably 5 or less. Preferably, D-glucose within 16 to 100 is connected to the linear chain by α-1,4 bonds by α-1,6-glucosidic bonds in the form of side chains. It is a form made. Due to such a binding structure, the highly branched cyclic dextrin has a cyclic alpha-glucan moiety.

  As described above, when the highly branched cyclic dextrin according to the present invention has conditions such as the average molecular weight, the equivalent value, and the number of measured D-glucose, it is easily dissolved in water to be more suitable for the purpose of the present invention, Inclusion ability of incense becomes more desirable.

  The highly branched cyclic structure dextrin derivative means that the present invention maintains the basic structure so that all the functions according to the present invention can be obtained from the structural features of the highly branched cyclic structure dextrin according to the present invention. Means a structure in which a part of atoms or atomic groups that do not affect the function of is substituted.

  Thus, in the composition according to the present invention, the use of a highly branched cyclic structure dextrin having a high degree of branching improves the ability of the composition to bind to undesired molecules on the treated surface. Even lower concentrations compared to dextrin derivatives can more effectively reduce or eliminate unwanted molecules on the surface.

  More specifically, as a structural feature of the highly branched cyclic dextrin according to the present invention, it absorbs various organic molecules or a part of organic molecules that match the shape of at least one internal space of the highly branched cyclic dextrin. Since it is made possible (to form a polymer), in addition to undesirable organic molecules including off-flavor molecules, foreign matter having a large surface can be taken into the internal space. Therefore, the highly branched cyclic structure dextrin according to the present invention having various sizes of interiors can not only remove off-flavors generated by organic aromatic molecules in a broad sense having various active groups, but also has excellent residual fragrance. In addition, various fragrance substances or odor eliminating substances having ClogP with good odor masking of 3 or more and a boiling point of 250 ° C. or more can be effectively transmitted.

  In order for the highly branched cyclic dextrin to function functionally within the composition, at least about 0.01 to 20% by weight, desirably about 0.05 to 10% by weight, more desirably about 0, in the total composition. .1-5% by weight can be present. When the above content is included, it is effective not only for removing off-flavors but also for transmitting fragrance ingredients. When highly branched cyclic dextrin is less than 0.01% by weight, the deodorizing effect is weak and exceeds 20% by weight. If this is the case, a problem will occur in the dosage form stability of the composition.

2) Fragrance The fragrance according to the present invention is included in at least one cyclic structure of the highly branched cyclic structure dextrin and forms a stable composition. The stable composition of the present invention provides a sensation quality of good fragrance, which removes foreign substances, i.e. off-flavors, and gives a refreshing feeling when treated on the surface of fabrics, human bodies and the like. The fragrance | flavor in this invention can provide the fragrance with at least lasting power.

  The fragrance | flavor which can be included in dextrin of the highly branched cyclic structure by this invention is characterized by being able to include various fragrance | flavors irrespective of a hydrophilic and hydrophobic fragrance | flavor, Such a point is characterized by the highly branched cyclic | annular form by this invention. It can be understood that a variety of fragrances can be included because a dextrin having a structure can include not only a fragrance that can be included in cyclodextrin but also a fragrance that cannot be included in cyclodextrin. That is, the fragrance | flavor included in the dextrin of the high molecular cyclic structure by this invention is not limited to a specific fragrance | flavor, It is characterized by including various fragrance | flavors.

  On the other hand, the aroma perfume is the ratio of alcohol to the perfume stock solution, and the aroma perfume according to the present invention is about 0% to about 3% of the total composition, desirably about 0.003% to about 2%. More desirably, it is about 0.005% to about 1%.

  In the present invention, a fragrance is added in order to eliminate off-flavors and further maintain the scent on the surface. When a strong incense is required, a perfume with a high perfume rate can be adopted or a perfume excellent in the feeling of residual scent can be used. Any type of perfume can be applied to the composition of the present invention, and the perfume component can be either hydrophobic or hydrophilic.

  In order to keep the scent longer, the perfume should have at least partial hydrophobicity and a relatively high boiling point. That is, incense mainly consists of incense raw materials belonging to the following two groups. (A) A fragrance component having a hydrophobic component of ClogP 3.0 or higher, preferably ClogP 3.5 or higher, and (b) 205 or higher, preferably 210 or higher, more preferably 220 or higher.

  The nature of the fragrance component is diverse in isomers and has a great influence on the substances present in the vicinity, so that it is difficult to clearly distinguish it from physical values such as ClogP and molecular weight. Therefore, the numerical values should be interpreted flexibly in the interpretation of the numerical ranges as approximate values for indicating the properties of the fragrance.

  For such hydrophobic perfumes, the weight ratio of highly branched cyclic dextrin to perfume is about 2: 1 to about 200: 1, desirably about 4: 1 to about 100: 1, more desirably about 6 : 1 to about 50: 1, more preferably about 8: 1 to about 30: 1 (highly branched cyclic dextrin: fragrance).

  The hydrophobic fragrance has a property of strongly binding to cyclic dextrin. The hydrophobicity of a fragrance component is related to the octanol / water splitting coefficient P of the component, and the octanol / water partition coefficient of a fragrance is the equilibrium concentration ratio of the fragrance in octanol and water. The higher the splitting factor P, the more hydrophobic, and the lower the splitting factor P, the more hydrophilic. Since the splitting coefficient of the fragrance is generally high, it can be conveniently shown in the form of log P using a log with a base of 10. Thus, other perfumes in the present invention have a log P value of about 3 or greater, desirably about 3.1 or greater, and most desirably about 3.2 or greater.

  Also, the composition of the hydrophobic perfume each comprises at least about 5% -80% by weight of the total perfume composition, desirably about 10% -60% by weight, more desirably about 15% -40% by weight.

  More specifically, the highly branched cyclic dextrin according to the present invention includes galaxolide, iso-E super, helvetolide, and cashmere which are fragrances that cyclodextrin could not be included. In addition, at least one perfume can be included from the group consisting of Cervolide, Aurantiol, and the like. Such a fragrance has excellent off-flavor masking ability, has a high preference for a fragrance, has a large molecular weight, and can more easily improve the scent sustainability as a hydrophobic fragrance.

  Table 1 below shows whether or not some residual fragrances can be combined with cyclodextrins and highly branched cyclic dextrins according to the present invention. Since the highly branched cyclic dextrin according to the present invention has a wider and wider internal space than cyclodextrin, it can include a perfume with a large molecular weight that cannot be contained in cyclodextrin with ClogP of 3.0 or more. it can. Therefore, since more perfumes can be applied using the highly branched cyclic dextrin according to the present invention, the perfume spectrum of the present composition can be broadened and the persistence of the remaining aroma can be increased.

  A perfume formulation for the present invention generally comprises at least four hydrophobic residual perfumes, desirably five, more desirably six, and even more desirably seven hydrophobic residual perfumes. The most widely used naturally derived fragrance is composed of a plurality of components.

  In addition, hydrophilic fragrances have a feature that they are well separated from highly branched cyclic dextrins in a water-soluble composition. Such hydrophilic fragrances mainly contain ClogP of about 3.5, preferably about 3.0 or less. It consists of ingredients.

  If the perfume ingredients are hydrophilic, they are dissolved in a water-soluble composition and the degree of binding with cyclic dextrin is not high. In order to maintain the function of the cyclic dextrin to reduce and remove foreign substances such as off-flavors, the hydrophilic fragrance has a weight ratio with the highly branched cyclic dextrin of about 90% by weight or less, desirably 50% by weight or less, and more desirably. Is preferably present at 30 wt% or less, more preferably 10 wt% or less. The ratio of cyclic dextrin to such hydrophilic perfume is desirably about 8: 1 or more, more desirably about 10: 1 or more, more desirably about 20: 1 or more, and most desirably about 70: 1 ( Cyclic dextrin: hydrophilic perfume) or more.

  Moreover, in this composition, in order that a fragrance | flavor may play the role, 0.1 to 10.0 weight% with respect to the weight of the whole composition, Preferably it can exist in 0.5 to 5.0 weight%, When the said content is included, the improvement of the sensitivity quality by an incense can be maximized.

3) Solvent
In the present invention, the solvent means a transporter, preferably water, and distilled water, water from which ions have been removed, and tap water can also be used. Water not only acts as a transporter for highly branched cyclic dextrins, but can also promote the binding of foreign matter such as off-flavor molecules on the treated surface with highly branched cyclic dextrins. In addition, it is known that if an aqueous solution is treated on a surface contaminated by a bad odor generated by an organic amine, acid, mercaptan, etc., which is polar and has a low molecular weight, the strength is reduced. The water used as the solvent of the present invention is considered to solubilize polar and low-molecular off-flavor molecules and reduce the off-flavor strength by reducing the vapor pressure.

  The concentration of solvent, i.e. water, used in the composition of the present invention may vary depending on the use of the composition (e.g., dosage form, etc.). Compositions for sprays that are passively or automatically sprayed desirably have a weight of water of about 30% to about 99.9%, more desirably about 50% to about 99% by weight of the total composition. .9% by weight, more desirably from about 60% to about 95% by weight, which is very high.

  In the composition for removing the off-flavor of the fabric, alcohol can be used as a solvent, and preferably a lower alcohol having 1 to 4 carbon atoms such as methanol or ethanol. The alcohol is used at a concentration of about 20% by weight or less, desirably about 10% or less, more desirably about 5% or less based on the total composition weight.

  Dilution of the aqueous solution can widen the application range of highly branched cyclic dextrins in textiles and maximize the chance that highly branched cyclic dextrin molecules and off-flavor molecules can be combined.

4) Surfactant The surfactant of the present invention may be further included in the composition of the present invention in order to appropriately reduce or remove foreign substances on the surface of the object or to allow the perfume component to perfume for a long time. Can do. For the proper removal of off-flavors, the surfactant contains a stable surfactant that can be easily combined with the highly branched cyclic dextrin according to the present invention, and is less susceptible to inclusion in the highly branched cyclic dextrin according to the present invention. It is important to form a polymer with an active substance, generate a low surface tension, and spread easily and uniformly on a hydrophobic surface such as a fabric.

  The surfactants used in the present invention are generally of the type used in detergents, softeners, shampoos, surface cleaners, cosmetics, body products, oral cleaners, body soaps, shaving products, moisturizing agents, and the like. Things can be included.

  A highly branched cyclic dextrin containing a stable surfactant can dry faster depending on the type and characteristics of the applied surfactant and remove off-flavors to the treated object more quickly. it can. Perfumes that do not dissociate well by inclusion with highly branched cyclic structure dextrin among the components of some compositions promote the formation of micelles or vesicles with highly branched cyclic dextrin and surfactant, and have the proper strength when used. Perfume is maintained and contributes to strengthening the advantage that the remaining scent is maintained longer during use from the treated surface.

  The binding force between the surfactant and the highly branched cyclic dextrin according to the present invention can be understood by confirming the change in interfacial tension (dyne / cm) depending on whether or not the highly branched cyclic dextrin is added to the surfactant aqueous solution. The aqueous surfactant solution includes surfactants at concentrations of about 0.5%, about 0.1%, about 0.01%, about 0.005%, and the surface tension of the aqueous surfactant solution at a given concentration and If the increase in interfacial tension of an aqueous solution containing the same concentration of surfactant and further containing about 1% by weight of highly branched cyclic dextrin is about 10% or more, strong binding between the surfactant and cyclic dextrin Indicates that exists.

  Desirable surfactants of the compositions according to the present invention desirably have the change in interfacial tension either weakly bound to cyclic dextrin (the interfacial tension increases at less than about 5%) or unbound (the interfacial tension is about 1). Rises below%).

  Typical surfactant concentrations in the compositions according to the invention are from about 0.01% to about 2%, preferably from about 0.03% to about 0.6% by weight of the total composition weight. % By weight, more desirably from about 0.05% to about 0.3% by weight. The concentration of surfactant in the concentrated surfactant composition is generally from about 0.1% to about 20% by weight, desirably from about 0.2% to about 15%, more desirably about 0.3%. % By weight to about 10% by weight, but is not limited thereto.

  Although the effective surfactant in this composition was illustrated as follows, it is not restrict | limited to these. Examples of this include block polymer surfactants, siloxane surfactants, anionic surfactants, amphoteric surfactants, cationic surfactants, castor oil surfactants, sorbitan ester surfactants, There are rated fatty alcohol surfactants, glycerol monovalent fatty acid ester surfactants, polyethylene glycol fatty acid ester surfactants, carbonized fluorosurfactants, and mixtures thereof.

  Examples of the block polymer surfactant include block polymers of ethylene oxide and propylene oxide, and Pluronic (registered trademark) and Tetronic (registered trademark) can be used.

The siloxane surfactant is preferably a polyalkylene oxide polysiloxane as an anionic surfactant, and has a dimethylpolysiloxane which is a hydrophobic portion and a polyalkylene chain which is more hydrophilic. Examples of such surfactants include Silwet®. The number of ethyleneoxy (—C ₂ H ₄ O) units in the polyether chain (R ¹ ) must be sufficient so that the polyalkylene oxide polysiloxane is water soluble. If a propyleneoxy group is present in the polyalkyleneoxy chain, it can be randomly located in the chain or present like a block. In addition to the surface activity, the polyalkylene oxide polysiloxane surfactant has additional effects such as antistatic and flexibility of the fabric.

  Examples of the anionic surfactant include alkyl diphenyl oxide disulfonate and alkyl ether sulfonate. Anionic surfactants usable in detergents and shampoos include ammonium lauryl sulfate, ammonium laureth sulfate, triethylamine lauryl sulfate, triethylamine laureth sulfate, monovalent ethanolamine lauryl sulfate, and monovalent ethanolamine laureth. Sulfate, diethanolamine lauryl sulfate, diethanolamine laureth sulfate, lauric monovalent glyceride sodium sulfate, sodium lauryl sulfate, potassium lauryl sulfate, potassium laureth sulfate, ammonium cocoyl sulfate, ammonium lauroyl sulfate, SO Diadium cocoyl sulfate, sodium lauroyl sulfate, potassium cocoyl sulfate, potassium lauroyl sulfate, triethanolamine lauryl sulfate, triethanolamine laureth sulfate, monovalent Ethanolamine cocoyl sulfate, a monovalent ethanolamine lauryl sulfate, Sodium N- Rauoiru -N-methyl taurate, sodium tridecyl benzene sulphates and sodium dodecylbenzene sulfate. Suitable detergent anionic surfactants for this composition are selected from ammonium laureth-3 sulfate, laureth chloride chloride, ammonium lauryl sulfate, lauryl sulfate chloride, and mixtures thereof. Such anionic surfactants are desirable because, when a cationic antibacterial activity system or an antiseptic is used, the binding between the cationic surfactant and the antibacterial system is reduced. Absent.

A variety of amphoteric surfactants can be used in the compositions of the present invention.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the invention to those skilled in the art.

<Example>
Since the composition according to the present invention consists of substances such as highly branched cyclic dextrin, fragrance and solvent, it is important that the function of highly branched cyclic dextrin is present in the composition during the production process of the present composition. In order to keep the highly branched cyclic dextrin having a function within the composition, the first highly branched cyclic dextrin and the surfactant must be mixed. As a result, after the formation of molecular polymers such as micelles and vesicles, highly branched cyclic dextrin-surfactant molecular polymers are impregnated with substances such as fragrances to impregnate highly branched cyclic dextrins. It is possible to retain a composition that effectively separates from the interior space and acts functionally within the composition.

  In the present invention, in order to remove the odor of fabrics, particularly dry fabrics, the compositions were prepared, applied and evaluated in spray form. However, the efficacy of the present invention is not limited to the dosage form. It is desirable to use a composition to which a highly branched cyclic dextrin with a low concentration is applied so as not to leave a stain on the fabric at a general use amount, such as a spray-type preparation used for removing the off-flavor of the fabric. The solution applied to the surface of the object under use conditions should not be visible after drying.

  Under general use conditions, the weight of the whole highly branched cyclic dextrin in the composition is usually about 0.01-20% by weight, desirably about 0.05-10% by weight, more desirably about 0.1-5%. % By weight. It is most desirable to include at least about 0.1% to 5% by weight in order to perform the function of a highly branched cyclic dextrin within the composition. A composition having a high concentration can leave a visible stain on the fabric as it dries, and can be problematic, especially in light and colored synthetic fabrics.

  The composition of the fragrance | flavor contained in one Example of this invention is as Table 2 below, and the content of the composition containing this is as Table 3.

1. Offensive Odor Strength Evaluation Evaluation on the off-flavor removal effect for the compositions of Comparative Examples and Examples was performed as follows.

1) For the evaluation fabric, a cotton towel cut at 30 cm × 30 cm is washed with a washing machine using an unscented detergent and dried with a dryer.
2) About 80 μL of off-flavor formulation is applied to a dry cotton towel in an area of 5 cm × 5 cm on each fabric, sealed in a plastic bag, and left overnight at room temperature.
3) A trained evaluator evaluates the initial off-flavor strength of the fabric coated with off-flavor, and gives a score according to the off-flavor evaluation scale below.
4) Next, the prescription to be evaluated is applied to the fabric in the same amount and dried for 30 seconds.
5) If the woven fabric is dry, the evaluator assigns a score to the odor intensity of the woven fabric to which the odor is applied according to the following odor rating scale.
6) Record the initial score and the subsequent score, and calculate the off-flavor reduction value with the score difference.

  There are 8 evaluators in total, and for the clear recognition of the standard odor, pre-trained evaluations are performed one by one in a single evaluation booth equipped with forced ventilation equipment to ensure the accuracy of the evaluation. In order to be expected, more than 3 evaluations were limited at one time.

Table 4 below shows the odor evaluation criteria.

  Moreover, for the evaluation of residual scent by cyclic dextrin, the scent intensity after 10 minutes and 30 minutes was evaluated, and the residual scent increasing effect of cyclic dextrin was evaluated.

Table 5 below shows the remaining scent evaluation criteria.

2. Evaluation results Apply about 80μL of off-flavor formulation to a cotton towel cut to 30cm x 30cm in an area of 5cm x 5cm on each fabric, put it in a plastic bag, leave it at room temperature overnight, As a result of evaluating the strength of the off-flavor by the panel, it was 4.2 points.

Table 6 shows the difference between the evaluation result after applying to Comparative Example 1 and Examples 1 to 7 and then drying for 30 seconds and the evaluation result of evaluating only the off-flavor source.

  It was found that Examples 1 to 7 using cyclic dextrin had an excellent off-flavor removing effect as compared with Comparative Example 1 using cyclodextrin as the off-flavor removing base. Comparing Comparative Example 1 and Example 1, only the off-flavor removal base is different. In Example 1 and Example 2, the content of the off-flavor removal base is the same, and only the type is different. . It can be seen that cyclic dextrin is superior to cyclodextrin for removing off-flavors when the off-flavor removing base has the same content.

  Moreover, in the case of Example 2 and Example 3, when Copolymer 958 which is a cyclic dextrin compatible polymer was applied, it turned out that the effect of removing the bad smell by cyclic dextrin increases. Comparing Example 4 and Example 5, it was found that Example 4 having a high content was more excellent when the fragrance content was changed to 0.10% and 0.06%, respectively. In addition, when Example 2 and Example 4 in which the application of Velvetex BK-35, which is an amphoteric surfactant, is compared, the results of Example 4 to which Velvetex BK-35 is applied are more excellent. I understood. By comparing Example 6 and Example 7, it was found that the addition of a cyclic dextrin-compatible polymer and an amphoteric surfactant that can provide a synergistic effect for removing the off-flavor of cyclic dextrin increases the off-flavor removal effect.

  Table 7 shows the results of evaluation of the afterglow intensity after 10 minutes and after 30 minutes. Comparing Comparative Example 1 with Examples 1 to 7, it was found that the residual scent attribute was further different after 30 minutes than after 10 minutes. It can be determined that cyclic dextrin has a ClogP of 3.0 or higher and a boiling point of 250 ° C. or higher, more fragrance components than cyclodextrin, and is released over time.

  Moreover, such a fact could be confirmed again from the result that the difference between the residual scent after 10 minutes and the residual scent after 30 minutes is smaller as the cyclic dextrin content is higher. From the comparison between Example 6 and Example 7, the effect of increasing the residual scent of cyclic dextrin is further increased when polymers and amphoteric surfactants that can increase the mutual adhesion between the fragrance and the fiber are added. Confirmed to do.

<Production of Examples 8 to 16 and Comparative Example 2>
When the deodorant compositions of Examples 8 to 16 and Comparative Example 2 were produced, the highly branched cyclic dextrin (HBCD) was an oligosaccharide (oligosaccharide) which is an odorless white powder having α-D-glucose as a monomer. Thus, a mixture having an average molecular weight in the range of about 30,000 to 1,000,000 per mole (g / mol) was used in the range of 0 to 0.8% by weight.

  The plant extract was prepared by mixing 50 g each of dry green tea, bamboo leaf, cinnamon, and octagonal aroma into 5 liters of purified water at 110 ° C for 60 minutes with hot water extraction, It was a plant extract obtained by reacting minerals such as, and was used in the range of 0 to 1% by weight.

  In addition to highly branched cyclic dextrin and plant extract, other surfactants, fragrances, additives and the like are added to purified water and mixed, and Examples 8 to 16 and Comparative Examples with the composition ratios shown in Table 8 below are mixed. 2 deodorant compositions were prepared.

3. Deodorizing power evaluation of the deodorant compositions of Examples 8 to 16 and Comparative Example 2 The deodorizing power test was trained against ammonia and methyl mercaptan against the detector tube, detection pump measurement method and food malodor of ASTM D1988. The sensory evaluation method, which is an evaluation of the odor intensity of the evaluator, was used.

  Methyl mercaptan is 0.1% benzene reagent grade, ammonia is 0.05% diluted in water and used as a source of malodor, food malodor is 0.1% kimchi chige in water Diluted to a concentration of The gas suction pump is manufactured by GV-100S Air Sampling Pump, Gastec co. (Japan), and the gas detector tube is Gastec Detector tube No. 71 (Methyl mercaptan), Gastec Detector tube No. 3La (Ammonia) was used.

  Evaluation of the deodorization rate for ammonia and methyl mercaptan is detected by putting a certain amount of purified water or sample stock solution into a 250 mL container, sealing with a malodorous solution, and sucking the detection tube with a gas suction pump after 10 minutes. The malodor concentration was listed.

  Deodorization rate is calculated by (detection tube malodor detection concentration when using purified water, ppm)-(detection tube malodor detection concentration when using sample, ppm) / (detection tube malodor detection concentration when using purified water) , Ppm) was multiplied by 100 (%) and the percentage was calculated and used as the deodorization rate.

  The deodorization rate for Kimchichige is evaluated by the trained evaluator using the evaluation scale to evaluate the initial malodor intensity of the fabric to which the malodor was applied. After the same amount of the prescription to be evaluated was applied to the fabric and dried for 30 minutes, the fabric was dried. The odor reduction value was calculated from the difference in evaluation scores for evaluating the odor intensity. Kimchichige's food malodor evaluation scale is evaluated by assigning a score of 0 to 5 points, and the higher the score, the better the deodorizing power.

  As a result of the evaluation, compared with Comparative Example 2 in which the plant extract was individually formulated, the highly branched cyclic dextrin was individually formulated, or the deodorant composition of Examples 8 to 16 in which the plant extract was mixed and formulated It was found that the product was excellent in deodorizing power against ammonia and methyl mercaptan and deodorizing power against kimchichige food malodor.
