Description

METHOD FOR PREPARING GELLED AROMATIC COMPOSITION [0002]

The present invention relates to a method for producing a fragrance composition on a gel, which is excellent in durability and heat resistance, and is excellent in sustained release properties and can be continuously diffused 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 method of making a fragrance composition in gel form.

A further object of the present invention is to provide a process for producing a gel-like fragrance composition which is capable of continuously emitting fragrance and which is excellent in sustained release properties.

Disclosure of the Invention An object of the present invention is to provide a method for producing 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.

Hereinafter, the present invention will be described in more detail with reference to Examples. It is to be understood that both the foregoing description and the following detailed description are exemplary, explanatory and are intended to be illustrative, and not restrictive. The scope of the invention is defined by the appended claims rather than by the foregoing description. will be.

FIG. 1 is a flow chart of a method for producing a fragrance composition according to an embodiment of the present invention. Referring to FIG. 1, a first mixture (S100) is prepared by mixing a first raw material and a liquid polymer; 2) preparing a second mixture by mixing a second binder and a crosslinking agent (S200); 3) mixing the first mixture of step 1) and the second mixture of step 2) to produce a third mixture (S300); And 4) aging the third mixture (S400). ≪ IMAGE > The first flavor and the second flavor are the same flavor.

(1) mixing the first dye and the liquid polymer to prepare a first mixture (S100), mixing the first dye with the liquid polymer, stirring the mixture at a temperature of 200 to 400 RPM for 30 minutes to 2 hours, 1 fragrance is dissolved in an organic solvent. Preferably, the liquid polymer is stirred at a temperature of 280-320 RPM for 50-70 minutes, more preferably at 300 RPM for 1 hour. When stirring at a speed of less than 200 RPM or for a time of less than 30 minutes, the first perfume is not sufficiently mixed with the liquid polymer, and precipitates may be formed. When stirring is carried out for a time exceeding 400 RPM or for more than 2 hours, Although the perfume can be completely dissolved in the liquid polymer, there is an undesirable problem for economical reasons such as evaporation of the perfume.

(2) mixing the second flavoring agent and the crosslinking agent to produce a second mixture (S200), mixing the second flavoring agent with the crosslinking agent, stirring at a rate of 50 to 150 RPM at room temperature for 5 to 25 minutes, 2 The perfume is completely dissolved in the crosslinking agent to prepare a crosslinking agent, preferably at a speed of 80 to 120 RPM for 8 to 12 minutes, more preferably for 10 minutes at a speed of 100 RPM. When stirring at a speed of less than 50 RPM or for less than 5 minutes, the second flavor is not sufficiently homogenized in the crosslinking agent, the gelation reaction does not occur uniformly, and when stirring is carried out for a time exceeding 120 RPM or for more than 25 minutes , It is possible to completely dissolve the second flavor in the cross-linking agent, but there is an economically undesirable problem such that the activity of the binder is reduced.

Step 3) S300 is a step of mixing the first mixture and the second mixture to prepare a third mixture, which is stirred using a stirrer at a speed of 50 to 150 RPM for 1 minute to 10 minutes, Can be stirred at a rate of 100 RPM, but are not limited to examples. If it is stirred at a speed lower than the speed of 50 RPM or less than 1 minute, the liquid polymer in the step 1) and the crosslinking agent in the step 2) may not be sufficiently mixed to cause non-uniform gelation, , There is a problem that it is difficult to control the gelation rate.

In the production method of the present invention, the same fragrance can be used for the first and second fragrances, and a gel-like fragrance composition that emits a desired fragrance can be prepared even when a liquid polymer containing a fragrance and a crosslinking agent are mixed. That is, when the flavor to be mixed with the liquid polymer and the flavor to be mixed with the cross-linking agent are different, there is a problem that the desired flavor can not be obtained due to the presence of the fragrance which differs in the mixing process of the liquid polymer and the cross- . Accordingly, when a fragrance composition of the present invention is produced by the same manufacturing method as that of the embodiment of the present invention, a fragrance-based gel composition that emits fragrance to be produced can be produced.

The gel-like perfume composition of the present invention may further comprise a nucleating agent. More specifically, the nucleating agent may be prepared by: 1-1) preparing a first mixture by adding a nucleating agent when the first dye and the liquid polymer are mixed; 2-1) when mixing the second flavor and the crosslinking agent, adding a nucleating agent to prepare a second mixture; 3-1) When mixing the first mixture of step 1) and the second mixture of step 2), the third mixture may be prepared by adding a nucleating agent.

The nucleating agent is a solid additive 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. The step of adding the nucleating agent can be selected in one of three steps as described above. That is, after mixing the first fragrance with the liquid polymer to prepare a liquid polymer containing the first fragrance, a method of adding a nucleating agent to the liquid polymer containing the first fragrance, mixing the second fragrance with the crosslinking agent, A step of adding a nucleating agent to the crosslinking agent containing the second perfume or a crosslinking agent comprising a liquid polymer containing the first perfume and a second perfume to prepare a crosslinking agent comprising the second perfume, The nucleating agent may be added to the mixture.

The nucleating agent is at least one selected from the group consisting of fumed silica, wet silica and mixtures thereof, and is preferably 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. Wherein the nucleating agent comprises from 0.01 to 3% by weight based on the total weight of the composition. If the content of the nucleating agent is less than 0.01% by weight, stability at a high temperature (60 ° C) If it is contained in an amount exceeding 3% by weight, there is a problem in stability, durability and sustained release at high temperature.

Wherein the gel-like perfume comprises from 10 to 30% by weight of a liquid polymer, from 1 to 5% by weight of a crosslinking agent and from 65 to 88.98% by weight of a perfume. 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 content 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 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.

Wherein the liquid polymer is a gel-like perfume composition wherein the weight ratio of liquid polymer and perfume is 1: 1 to 1: 2.17. When the dyestuff contains less than 100% by weight or more than 217% by weight of the liquid polymer, it is difficult to uniformly control the gelation reaction in the cross-linking reaction.

The cross-linking agent relates to a gel-like perfume composition wherein the weight ratio of cross-linking agent and flavoring is from 1:13 to 1:26. When the content of the antioxidant is less than 130% 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.

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 FIGS. 2 and 3.

FIGS. 2 and 3 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 1 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 1 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.

4 is a graph showing the maximum stress, strength, hardness, and yield of the gel-like fragrance composition according to the content of the 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.

Example  3

Heat resistance test of the fragrance composition of gel

The gel-like fragrance compositions of Preparation Examples 1 and 2 and the gel-like fragrance compositions of Comparative Examples 2 and 3 were stored at 60 ° C for 4 weeks to observe whether the gel phase was maintained.

Comparative Example 2 Production Example 1 Production Example 2 Comparative Example 3 Storage at 60 ° C for 4 weeks record Does not melt Does not melt record

According to Fig. 5 and Table 1, the gel-like perfume compositions of Preparation Examples 1 and 2 were kept in the gel phase even after storage at 60 DEG C for 4 weeks. However, the gel-like perfume compositions of Comparative Examples 2 and 3, when stored at 60 ° C for 4 weeks, melted without maintaining the gel phase.

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 2 and 3, 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. 6 is a graph showing the result of measuring the daily 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. 6, in the case of Comparative Example 1 in which no nucleating agent is added, the initial volatilization amount shows a large value, but as the volatilization amount decreases over time, When 3% by weight of the nucleating agent is added, it is confirmed that similar volatility is maintained until the latter stage, which is a gel-like fragrance composition having excellent sustained release properties.
