Description

[0001] GELED AROMATIC COMPOSITION [0002]

The present invention relates to a gel-like fragrance composition, which is excellent in durability and heat resistance, is excellent in sustained release properties, and is capable of continuously emitting a fragrance for a long period at a certain place.

In recent years, efforts have been made to comfort the indoor air as the environment has been threatened by the rapid change of the environment due to a lack of pleasant living environment and a decrease in the natural purification rate. The aromatic agent, which is typically used to purify the indoor air, is first used for masking odor of a toilet or the like with a strong fragrance. However, nowadays, it has wide range of applications for aromatherapy, indoors, and even for mental treatment.

Conventionally, as a fragrance constituting such a fragrance product, a liquid component having relatively high volatility is often used in order to easily diffuse into the air. In this case, a liquid component is stably provided, A fragrance product having a specific type of closed container for allowing the liquid to evaporate and to be discharged to the outside while limiting the permeation of the liquid to the liquid material so as to faithfully carry out the directional function by the component divergence is required .

A container having a shape which is commonly used and which is formed in such a manner that an inner space and an outer space of the container are blocked, one end of which is in contact with the liquid phase of the inner space and the other end of which is exposed to the outside of the container, Those that cover the inlet of the vessel and contain a membrane of special material that prevents permeation of the liquid and permeates only the vaporized gas has been used.

Therefore, in the case of a fragrance product containing the above-mentioned liquid fragrance, it is difficult to manufacture containers and product packaging processes due to the special structure, shape, or the necessity of having a container containing a special material member. Even if the container was transported well or the container tumbled, the liquid component often flowed out or overflowed the container, which made it difficult to store and transport the container.

On the other hand, a fragrance product containing a fragrance in a solid state is provided as a solution to the problem described above in Korean Patent Laid-Open No. 10-2004-0065095. As such a type of fragrance, it is common to use a fragrance produced in a solid lump state by appropriately compounding various chemical components including a fragrance component. The direction component of the fragrance of the solid phase is directly sublimated into the vapor phase, Unlike the previous example, since the fragrance does not flow or spill over, it does not require a sealed container and is relatively easy to move and store, which is advantageous for stable use in a somewhat unstable place such as a moving vehicle There is a dot.

However, due to problems such as shaking, when a shock is applied to the fragrance in the storage, when the fragrance is damaged by the shock or when the temperature is relatively high at 40 ° C or more, the fragrance of the solid state is liable to be liquefied, There is a disadvantage in that when it is liquefied, it causes contamination of the surrounding space due to the structure of the container which is poor in hermeticity.

In order to solve such a problem, it is urgent to develop a fragrance which is excellent in durability and heat resistance and can continuously produce fragrance.

The present invention relates to a gel-like perfume composition.

It is an object of the present invention to provide a gel-like perfume composition excellent in sustained release properties capable of continuously emitting fragrance.

Another object of the present invention is to provide a gel-like fragrance composition which is excellent in durability and heat resistance, does not cause damage to impact, and does not liquefy even when stored at a high temperature for a long time.

In one embodiment of the present invention, the liquid polymer comprises a liquid polymer and a crosslinking agent, wherein the liquid polymer is a liquid polymer containing a first perfume, the crosslinking agent is a crosslinking agent comprising a second perfume, 2 < / RTI > fragrance is the same fragrance and further comprises a nucleating agent.

The embodiments of the present invention are described in order to more fully explain the present invention to those skilled in the art, and the following embodiments may be modified in various other forms, The present invention is not limited to the embodiment. Rather, these embodiments are provided so that this disclosure will be more faithful and complete, and will fully convey the scope of the invention to those skilled in the art.

In the drawings, the thickness and size of each layer are exaggerated for convenience and clarity of description, and the same reference numerals refer to the same elements in the drawings. As used herein, the term "and / or" includes any and all combinations of one or more of the listed items.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the singular forms "a," "an," and "the" include singular forms unless the context clearly dictates otherwise. Also, " comprise "and / or" comprising "when used herein should be interpreted as specifying the presence of stated shapes, numbers, steps, operations, elements, elements, and / And does not preclude the presence or addition of one or more other features, integers, operations, elements, elements, and / or groups.

The liquid polymer of the present invention means a liquid-phase polymer.

The crosslinking agent of the present invention is characterized in that a complete chemical bond such as a covalent bond or an ionic bond is formed between a molecule and a molecule to form a crosslinked bond or a bridge between an atom and an atom bonded in a side chain Means a compound for forming a bridge bond or a cross-link by a bond to be formed.

The gel of the present invention is a state in which the sol has lost fluidity. The elastic gel is called jelly and contains a large amount of solvent. These are solidified molecules of colloidal particles between the net tissues, and if the temperature is raised again, it means that the tissue is destroyed by molecular motion or other causes and becomes fluid liquid again.

The perfume of the present invention means an organic substance having a strong aroma added for adding a perfume and excellent in volatility at room temperature.

In one embodiment of the present invention, the liquid polymer comprises a liquid polymer and a crosslinking agent, wherein the liquid polymer is a liquid polymer containing a first perfume, the crosslinking agent is a crosslinking agent comprising a second perfume, 2 < / RTI > fragrance is the same fragrance and further comprises a nucleating agent. The gel-like fragrance composition largely includes a liquid polymer, a crosslinking agent and a nucleating agent. However, it is characterized in that it is a crosslinking agent comprising a liquid polymer containing a first perfume and a second perfume. That is, before mixing the liquid polymer and the crosslinking agent, the first perfume is mixed with the liquid polymer, and the second perfume is mixed with the crosslinking agent. However, the first fragrance and the second fragrance contained in the liquid polymer and the crosslinking agent are the same fragrance. When the liquid polymer and the cross-linking agent are mixed using separate fragrances, when the liquid polymer containing the fragrance and the cross-linking agent are mixed, the fragrance inherent in the fragrance disappears due to the chemical action between the fragrance, And in this case, there is a problem that the fragrance of the produced gel-like perfume composition can not be predicted.

The natural flavoring agent can be, for example, lemon grass oil, cumin oil, marjoram oil, basil oil, clover oil and bay oil, bergamot, marjoram, phytoncide, thyme, lavender, eucalyptus Etc., and are not limited to examples.

In one embodiment of the present invention, the gel-like perfume composition is characterized by comprising a nucleating agent, wherein the nucleating agent is at least one selected from the group consisting of fumed silica, wet silica and mixtures thereof, Is a fumed silica. Nucleating agents are solid additives for improving heat resistance and durability. By including the nucleating agent in the mixture of the liquid polymer and the crosslinking agent, the nucleating agent in the network structure due to the crosslinking serves to physically have a rigid structure. That is, it serves as a support on the network structure due to crosslinking, and the heat resistance and durability can be improved owing to this supporting role. The network structure is a structure in which the skeleton forming the polymer is formed in a three-dimensional mesh shape, and includes a nucleating agent to perform a role for firmly supporting the network structure.

In one embodiment of the present invention, the liquid polymer is at least one selected from the group consisting of polybutadiene, polyisoprene, and polychloroprene. The composition is preferably a gel-like perfume composition, preferably oligo-butadiene or polybutadiene polybutadiene), and more preferably maleinized polybutadiene.

In one embodiment of the invention, the crosslinking agent is a compound comprising at least one amine group and is preferably selected from alkylpropyldiamine, polyoxyalkylene diamine, polyoxyalkylene triamine, oleylamine, cocoamine, poly Butadiene, and mixtures thereof, and is more preferably at least one selected from the group consisting of polyoxyalkylenediamine.

In one embodiment of the present invention, the gel-like perfume comprises 10 to 30% by weight of a liquid polymer, 1 to 5% by weight of a crosslinking agent, 0.01 to 3% by weight of nucleating agent and 65 to 88.98% In-gel fragrance composition. When the amount of the liquid polymer is less than 10% by weight, the gel structure is difficult to accommodate all of the perfume, leakage occurs, and the temperature stability of the gel is deteriorated. When the amount exceeds 30% by weight, gel shrinkage due to volatilization There is a problem that the perfume does not smooth smoothly, and the persistence of the volatilization of the fragrance is reduced due to such a problem, and some fragrance volatiles are not volatilized and are trapped in the gel. When the content of the nucleating agent is less than 0.01% by weight, stability at high temperature (60 ° C) becomes a problem. When the content exceeds 3% by weight, there is a problem in stability, durability and sustained release at high temperature. When the fragrance is contained in an amount of less than 65% by weight, the strength is weakened and the fragrance has a short duration of fragrance. When the fragrance is contained in an amount exceeding 88.98% by weight, there is a problem of stability at high temperature. There is a problem that the profits are not great. When the crosslinking agent is contained in an amount of less than 1% by weight, there is a problem that the crosslinking agent contained is too small, sufficient crosslinking reaction does not occur to form a gel phase, and the gel phase can not be maintained. There is a problem in that the physical properties of the gel are hardened and the shrinkage rate due to volatilization is reduced and there is a problem that it is difficult to visually grasp the volatilization phenomenon due to the reduction of the shrinkage rate and the crosslinking reaction is rapidly increased and the hardening occurs in the manufacturing process.

In one embodiment of the present invention, the liquid polymer is a gel-like perfume composition having a weight ratio of liquid polymer and perfume of 1: 1 to 1: 5. When the content of the dye is less than 100% by weight or more than 500% by weight of the liquid polymer, it is difficult to uniformly control the gelation reaction in the crosslinking reaction.

In one embodiment of the present invention, the crosslinking agent is a gel-like perfume composition in a weight ratio of 1: 1 to 1: 26 of crosslinking agent and perfume. When the content of the filler is less than 100% by weight or more than 2600% by weight based on the weight of the crosslinking agent, it is difficult to uniformly control the gelation reaction in the crosslinking reaction.

The present invention relates to a gel-like fragrance composition comprising a liquid polymer comprising a first fragrance and a crosslinking agent comprising a second fragrance, wherein the first fragrance and the second fragrance are the same fragrance, The present invention relates to a gel-like fragrance composition which does not melt a gel phase even when it is stored at a high temperature for a long time, does not cause gel damage due to external impact, and can continuously emit a fragrance for a long time.

Example 2

Durability test of the fragrance composition of gel

(1) The maximum stress, strength, hardness and yield value of the gel-like fragrance compositions of Production Examples 1 to 3 and the gel-like fragrance compositions of Comparative Examples 1 to 3 were measured to test the durability of the gel-like fragrance composition.

As a concrete test method, the physical property was measured with a Rheo meter (use model: sun-compact-100II), and a 1.77 cm ² adapter was compressed perpendicularly to the gel surface at a rate of 120 mm / min to measure the physical properties. The results are shown in Fig.

1 is a graph showing the maximum stress, strength, hardness and yield of a gel-like fragrance composition according to the content of nucleating agent. When the fumed silica is not included, it shows a lower value than the gel-like fragrance composition containing the nucleating agent at the maximum stress, strength, hardness and yield strength. The fumed silica, which is the nucleating agent, It is understood that the composition is similar to that of the gel-like fragrance composition prepared without addition of the nucleating agent at the maximum stress, strength, hardness and yield value when the weight percentage is included. According to the above test results, , And 1 to 3 wt% of the nucleating agent, the maximum stress, strength, hardness, and yield value were found to be the most effective.

(2) The strength and hardness of the gel-like fragrance composition of Production Example 1 and Comparative Example 3 were measured. This is for evaluating the strength and hardness of the gel-like fragrance composition according to the difference in injecting time of the nucleating agent, and the results are shown in FIGS.

FIGS. 4 and 5 show the uniformity of cross-linking by measuring the strength and hardness of the gel-like perfume composition of Preparation Example 1 and Comparative Example 3 at the central portion and the edge portion. As a result, it was confirmed that the gel-like fragrance composition of Production Example 1 had homogeneous gel strength and hardness at the center and edge, resulting in uniform cross-linking reaction. On the other hand, it was confirmed that the gel-like perfume composition of Comparative Example 3 had a gel having a non-uniform crosslinking reaction due to a significant difference in strength and hardness at the center and at the edge. That is, depending on the method of injecting the nucleating agent, a difference may occur in the uniformity of the cross-linking reaction of the prepared gel-like fragrance composition, and the gel-like fragrance composition according to an embodiment of the present invention may have a uniform cross- Whereas, in the case of a gel-like perfume composition in which a liquid polymer, a crosslinking agent, a perfume, and a nucleating agent were simultaneously mixed, a non-uniform gel-like perfume composition was prepared.

Example 3

Heat resistance test of the fragrance composition of gel

The gel-like perfume compositions of Preparation Examples 1 and 2 and the gel-like perfume compositions of Comparative Examples 1 and 2 were stored at 60 ° C for 4 weeks to observe whether the gel-like compositions remained.

Comparative Example 1 Production Example 1 Production Example 2 Comparative Example 2 Storage at 60 ° C for 4 weeks Melting Not melted Not melted Melting

According to Fig. 2 and Table 1, the gel-like fragrance composition of Preparation Examples 1 and 2 was retained even after storage at 60 DEG C for 4 weeks. However, the gel-like perfume compositions of Comparative Examples 1 and 2 melted without maintaining the gel phase when stored at 60 ° C for 4 weeks.

That is, if the nucleating agent is not added at all, or if it contains more than 3% by weight, the gel-like perfume composition will not have a good heat resistance. In view of the temperature inside the automobile in summer, It is meant that it is not suitable for use as a fragrance for interior use in automobiles in summer. In this respect, it is said that the gel-like fragrance composition according to one embodiment of the present invention has excellent heat resistance.

Example 4

The gel-like fragrance composition Fragrance Experiment

In order to test the odor of the gel-like fragrance compositions of Production Examples 1 to 4 and the gel-like fragrance compositions of Comparative Examples 1 and 2, the daily volatilization amount of the fragrance composition of the gel was measured.

Specifically, in order to measure the daily volatilization amount, the microbalance was measured with a weight change amount of gel per day in a thermostat at 30 ° C, and the result is shown in FIG.

FIG. 3 is a graph showing the results of measurement of volatilization amount for 49 days. The perfume composition must continuously emit fragrance, and this effect is referred to as sustained release. That is, when the daily volatilization amount is measured, the volatile amount similar to the initial volatilization amount should be continued until the late period.

As shown in FIG. 3, in the case of Comparative Example 1 in which no nucleating agent was added at all, the initial volatilization amount showed a large value, but as the volatilization amount decreased over time, To 3% by weight, it can be confirmed that similar volatility is retained until the later stage, which is a gel-like fragrance composition having a good sustained release property.
