Description

[0001] Fluid deodorant composition improved fragrance durability [0002]

The present invention relates to a liquid deodorant composition which can be used as a deodorant such as a fiber deodorant, and more particularly, to a micelle-type liquid deodorant composition containing an aroma oil which is environmentally friendly and improved in fragrance persistence.

Many odors that can be encountered in everyday life cause people to feel uncomfortable, and they easily permeate into textile products such as clothes, curtains and carpet bedding, and stinks remain for a long time. In order to remove these odors, washing is most preferable, but in the case of curtains and bedding that are difficult to wash, a fiber deodorant is used to easily remove odors. In recent years, odor can be easily removed without applying a deodorant to the clothes.

The deodorization method of the fiber deodorant includes the chemical removal method, the physicochemical removal method, the biochemical removal method, and the sensory removal method. The chemical removal method is a method of converting a malodorous substance into a decomposing or odorless compound by using a chemical reaction such as neutralization, addition polymerization, oxidation reduction, hydrolysis, etc., . The physicochemical removal method is a compound having strong adsorption and adsorption ability such as activated carbon, silica, and cyclodextrin, adsorbing or collecting odorous components on the surface thereof, coating the surface with an absorbing liquid paraffinic alcohol synthetic resin or the like with a high boiling solvent surfactant or the like It is a method to remove odor materials. The biochemical removal method is a method of disinfecting the offensive odor component by the bacteria or removing the odor by decomposing the organic acid which is a malodor component by using digestive enzymes, bacteria and yeast. In addition, the sensory elimination method is a method of eliminating odor masking by using sensory neutralization or odor by using a directional perfume for the target odor component. A variety of fiber deodorizers have been developed using such a method for removing odors, and among them, the removal method using a masking method has been widely used because it can remove the odor most easily.

Most of the fiber deodorizing agents have not been used to remove the odor components themselves, but have mainly used masking methods using incense. However, since the odor components are left intact, the smell is felt again when the fragrance is lost. It is not appropriate. BACKGROUND ART [0002] In recent years, development of deodorization technology for fundamentally removing a bad odor component from garments and fibers has been actively under way. As a typical method, cyclodextrin, which is a cyclic polysaccharide, and a metal mineral component are added as a main component, and masking fragrance is added to spray the surface of garments and fibers for deodorization. This technique uses a method of chemically decomposing odorous substances during metal ion masking and removing odorous substances by encapsulating the decomposed odorous substances while the water is being dried.

Mastic is a kind of sap that is extracted from Fistaceae Lantuscus, a kind of pistachio tree that grows in Chios Island, Greece, and is a water-insoluble, insoluble substance. Mastic has been found to have the effect of inhibiting or killing the growth of Helicobacter pylori, which is known as a cause of gastritis, gastric ulcer and duodenal ulcer, and is widely used for the production of functional foods such as various drinks, toothpaste, and cosmetics. However, since the mastic is an extremely poorly soluble substance which does not completely dissolve in water, it can not be developed into a variety of products, and even if it is formulated, its absorption rate is low, so it is difficult to expect its efficacy and effectiveness.

Polymeric micelles are formed by micelles and polymers formed from surfactants, which are widely used for solubilization. Polymeric micelles have the advantage that they can dissolve poorly soluble materials such as mastic. Polymeric micelles are particles of 100 nm or less in diameter formed by amphiphilic polymers in an aqueous solution, and amphiphilic block copolymers are assembled in an aqueous solution to form a micelle composed of an inner hydrophobic region and an outer hydrophilic region , Which is a system that encloses hydrophobic drugs inside the micelle. Since block copolymers can produce various physical properties through the kind and composition ratio of the polymer monomer, the micelle using the polymer maintains more physical stability than the micelle using the surfactant, and the relatively low critical micelle concentration ), The stability in the body can be further improved.

Also, the fiber deodorant developed with conventionally known aroma oils, glycol solubilizers, triblock copolymers [PEO-PPO-PEO] and polyoxyethylene surfactants was not stable and precipitates formed over time. In addition, organic or inorganic synthetic antimicrobial and deodorizing agents for inhibiting the growth of microorganisms and removing odor caused by microorganisms cause side effects such as rashes and itching when they are used in daily necessities such as clothes, bedclothes, and shoes Or by-products which are not necessary in the manufacturing process are discharged, thereby polluting the environment.

FIGS. 2A to 2C are graphs showing the encapsulation rate of a liquid deodorant composition having improved perfume persistence according to a preferred embodiment of the present invention. FIG.
3 is a photograph showing stability test results of a liquid deodorant composition having improved perfume persistence according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying tables and drawings.

The present invention comprises an aroma oil and a liquid composition,

The liquid composition comprising 2 to 27% by weight of a glycol solubilizer; 5 to 60% by weight of triblock copolymer [PEO-PPO-PEO]; 25 to 65% by weight of a polyoxyethylene surfactant; 0.5 to 15% by weight of a natural antimicrobial antibiotic; and a perfume persistence improved liquid deodorant composition.

Specifically, the aroma oil is one of natural extracts, and in the present invention, the deodorant composition can have a perfume. More specifically, the aroma oil is mixed with the following liquid composition so that the aroma odor can be smelled in the liquid deodorant composition. The aroma oil can be mixed with the following liquid composition at an appropriate composition ratio in consideration of the taste of the user have.

The aroma oil may be one or more selected from natural extracts or synthetic perfumes.

At this time, the composition ratio between the aroma oil and the liquid composition contained in the liquid deodorant composition according to the present invention may be various composition ratios as long as the aroma oil can perform an erodible function, and preferably 100 parts by weight of the aroma oil And a composition ratio of 0.5 to 10 parts by weight. Of course, depending on the taste of the user, the composition ratio of the aroma oil to the liquid composition may have a value other than the above range.

Further, in the liquid deodorant composition according to the present invention, the liquid composition includes a glycol-based solubilizer, a triblock copolymer (PEO-PPO-PEO), a polyoxyethylene surfactant, and a natural antimicrobial antibiotic.

That is, the glycol solubilizer serves to dissolve the aroma oil and the natural antibacterial antibiotic. Further, at least one selected from the group consisting of polyethylene glycol, propylene glycol, and tetraglycol can be used as the glycol solubilizer, and it is preferable to use polyethylene glycol.

In addition, the glycol solubilizer may be used in combination with glycofurol, polysorbate, cremophor, Solutol HS 15, and the like.

The glycol solubilizer is preferably contained in the liquid composition at a composition ratio of 2 to 27% by weight based on the total weight of the liquid composition. That is, when the glycol solubilizer is contained in an amount of less than 2% by weight in the liquid composition, the dispersion of the natural antimicrobial antibiotic substance becomes incomplete and the release of the natural antimicrobial antibiotic substance becomes difficult. There is a problem that the particle size of natural antimicrobial antibiotics increases.

In addition, in the liquid deodorant composition according to the present invention, the triblock copolymer [PEO-PPO-PEO] contained in the liquid composition can form a micelle, thereby enclosing the natural antimicrobial antibiotic dissolved in the glycol- can do. The triblock copolymer [PEO-PPO-PEO] may be at least one selected from the group consisting of Poloxamer 184, Poloxamer 185, Poloxamer 188, Poloxamer 124, Poloxamer 237, Poloxamer 338 and Poloxamer 407 Is preferably used.

The triblock copolymer [PEO-PPO-PEO] is preferably contained in an amount of 5 to 60% by weight based on the total weight of the liquid composition, and the triblock copolymer [PEO-PPO-PEO] If the content of the antimicrobial antibiotic is less than 10% by weight, the natural antibacterial antibiotic substance precipitates rapidly. If the content exceeds 60% by weight, the particle size of the natural antibacterial antibiotic substance increases.

In addition, in the liquid deodorant composition according to the present invention, the polyoxyethylene surfactant contained in the liquid composition serves to increase the solubility of the natural antimicrobial antibiotic on the glycol solubilizer.

The polyoxyethylene surfactant is preferably contained in an amount of 25 to 65% by weight based on the total weight of the liquid composition. When the polyoxyethylene surfactant is contained in an amount of less than 25% by weight based on the total weight of the liquid composition, There is a problem that the natural antimicrobial antibiotic substance precipitates quickly in the glycol solubilizer. If it exceeds 65% by weight, toxicity due to the polyoxyethylene surfactant appears.

In the liquid deodorant composition according to the present invention, the natural antimicrobial antibiotic substance contained in the liquid composition can be used alone or in combination with natural antimicrobial antibiotic substances which are difficult to be solubilized, and the mastic powder, , And it is most preferable to use the mastic alone, but the present invention is not limited thereto.

The natural antimicrobial antibiotic is preferably contained in an amount of 0.5 to 15% by weight based on the total weight of the liquid composition. When the natural antimicrobial antibiotic is contained in an amount of less than 0.5% by weight based on the total weight of the liquid composition, antimicrobial effect If the content exceeds 15% by weight, a natural antimicrobial antibiotic substance which can not be encapsulated in the micelle due to excessive relative composition ratio of the natural antimicrobial antibiotic to the triblock copolymer [PEO-PPO-PEO] There arises a problem that can exist excessively.

In addition, the liquid composition having the above-described composition may further comprise additives in order to further improve the functionality of the liquid deodorant composition according to the present invention. At this time, it is preferable that the additive is contained in a composition ratio of 1 to 25% by weight based on the total weight of the liquid composition irrespective of kinds.

That is, if the additive is contained in an amount less than 1% by weight based on the total weight of the liquid composition, it is difficult to realize the functionality by the additive. When the additive is contained in an amount exceeding 25% by weight, , There arises a problem that the antimicrobial activity by natural antimicrobial antibiotics is relatively lowered.

Further, the additive may be composed of any one or more of a fluorescent whitening agent, a coloring matter, a stabilizer, a pH adjusting agent or an antioxidant so that the color of the object to be deodized sprayed with the liquid deodorant according to the present invention is brightened by the fluorescent whitening agent, Thus, it is possible to prevent the deodorant from having a beautiful color, or to stabilize the micelle by the stabilizer and the pH adjusting agent, or to easily oxidize and deodorize the entire deodorant composition by the antioxidant.

In connection with the above, the additive can adsorb or collect the odor component on the surface by the physicochemical removal method of the deodorant composition according to the present invention, thereby not only can additionally remove the odor but also the stability of the micelle And a cyclodextrin which serves to increase the amount of the cyclodextrin. That is, the cyclodextrin may be at least one selected from the group consisting of? -Cyclodextrin,? -Cyclodextrin, and? -Cyclodextrin as the cyclic polysaccharide.

In addition, when the additive is composed of cyclodextrin, if the cyclodextrin is contained in an amount of less than 1% by weight based on the total weight of the liquid composition, the amount of cyclodextrin is small so that the micelle containing the natural antimicrobial antibiotic is not encapsulated in the cyclodextrin And when it is contained in an amount of more than 25% by weight, there arises a problem that the excess cyclodextrin precipitates.

The aroma oil, the glycol solubilizer, the triblock copolymer [PEO-PPO-PEO], the polyoxyethylene surfactant, and the natural antimicrobial antibiotic contained in the liquid deodorant composition according to the present invention having the above- In one embodiment, the liquid deodorant composition is prepared by dissolving aroma oil, a glycol solubilizer, and a natural antimicrobial antibiotic material by stirring with heating to form a lysate, Triblock copolymer [PEO-PPO-PEO] may be added and mixed.

That is, when the aroma oil, the glycol solubilizer and the natural antimicrobial antibiotic are heated and stirred to produce the solubilized product, the effect of dissolving the aroma oil and the natural antimicrobial antibiotic in the glycol solubilizer can be more excellently dispersed PEO-PPO-PEO] is added to the above-mentioned lysate to form micelles in the lysate, and natural antimicrobial antibiotics, which are uniformly dispersed and dissolved in the glycol solubilizer, are more easily enclosed in the micelles The effect can be realized.

At this time, the heating temperature for making the melt can be appropriately adjusted according to the judgment of a person skilled in the art, and it is preferable to maintain the heating temperature at 40 to 70 ° C.

In connection with the above, the mixing order of the polyoxyethylene surfactant is mixed with aroma oil, glycol solubilizer and natural antimicrobial antibiotic according to the judgment of a person skilled in the art, and a natural antimicrobial antibiotic substance Or may be configured to be mixed with the triblock copolymer [PEO-PPO-PEO] into the melt after the melt is made.

That is, the liquid deodorant composition is prepared by dissolving aroma oil, a glycol solubilizing agent and a natural antimicrobial antibiotic material by heating and melting them to prepare a melt, adding a polyoxyethylene surfactant and a triblock copolymer [PEO-PPO-PEO ], And the mixture is stirred by heating.

When the polyoxyethylene surfactant is added to the melt heated to a predetermined temperature, the natural antimicrobial antibiotic substance dispersed and dissolved in the glycol solubilizer is dissolved in the triblock copolymer [PEO-PPO-PEO] It is possible to realize the effect of allowing solubility to be increased again before being encapsulated in the micelle formed by the method of the present invention.
