Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combustion type scent composition which emits a fragrance contained therein by combustion to the surroundings,
In particular, the present invention relates to a combustion-type scent composition having a scent with a high quality and satisfactory degree of intensity and spread.

[0002]

2. Description of the Related Art In a stressful modern society, having time to relax both physically and mentally is attracting attention as a very important factor in daily life. Recently, aromatherapy (aroma therapy), which is intended to relax the mind and body and obtain physiological and psychological effects by smelling a pleasant scent, has been particularly attracting attention. In response to this, the demand for arranging natural scents in indoor spaces has been rapidly increasing due to the trend of so-called naturalists and the like who prefer to live in nature and prefer to live in nature. .

[0003] In order to meet these demands, various types of products have been sold in order to provide a fragrance composition such as a liquid or a solid containing a fragrance component having a desired scent, particularly a fragrance component, as an indoor fragrance. ing. Generally, this type of fragrance is installed indoors, and the fragrance is diffused into the room by natural volatilization (in a room temperature environment) of the contained fragrance component, thereby trying to fill the room with the fragrance.

[0004] In addition, as in the case of "scent", which has been widely used since ancient times as a concept including incense, it promotes the volatilization of the fragrance component contained therein by burning itself, and has a natural and relatively strong strength. Those which continuously generate a certain fragrance are also known. More recently, so-called "perfume candles" have also become widely available which contain the appropriate perfume in the candle material and are configured to generate fragrance upon burning.

[0005] In the specification of the present application, it is possible to have a form such as "scent" and a scented candle, which itself burns to promote the volatilization of the scent component contained therein and emits a scent. A scent composition of the type is defined as "burnable scent composition" and will be used in the text. The non-burning fragrance composition has a weak scent when not burned, and its spread is not sufficient, but the burning increases the strength and spread of the scent and maintains the strength and spread during burning. What can be included. The emitted scent also includes a normal scent, and may include a wide variety of scents as described later.

[0006]

The above-mentioned fragrance which fills the fragrance by volatilization at room temperature is naturally susceptible to a change in temperature, and has a good quality for a specific time, that is, a relaxing time. It is difficult to obtain this even if you seek the strength and spread of fragrance. On the other hand, a combustion type scent composition represented by the above-mentioned “perfume candle” and “scent” can be said to be more preferable because a scent can be generated when desired by burning.

However, these combustion-type scent compositions are generally produced by directly adding a fragrance to a base material, which is a main constituent material, so that a satisfactory combustion-type scent composition cannot be obtained in many cases. Was. That is, the combustion-type scent composition obtained by directly scenting the base material shows a certain degree of intensity and spread of the scent by burning, but the achievement degree is insufficient or inefficient. In many cases, it was not possible to obtain a scent with sufficient intensity and breadth enough to satisfy the user.

[0008] In order to solve such a problem, it is conceivable to increase the amount of the fragrance contained to increase the strength and spread of the fragrance. Alteration of the fragrance has occurred, causing another problem that a desired fragrance cannot be obtained. As described above, an object of the present invention is to provide a combustion-type scent composition which is capable of exhibiting an efficient, high-quality, satisfactory intensity and spreading scent when used by burning. is there.

[0009]

Means for Solving the Problems In order to achieve the above object, a combustion type scent composition of the present invention comprises a combustible base and a fragrance, and the combustion type scent composition promotes generation of a scent by burning. The scent composition is characterized in that a fragrance adjusting agent for adjusting the generated scent is blended. The combustion type scent composition of the present invention further contains a fragrance modifier in addition to the base and fragrance which are the original constituent materials. In other words, the inventors of the present application focused on the fact that when a fragrance having a relatively high volatility was directly mixed into the base, the problem was noticeable in terms of the quality, strength, and spread of the fragrance, and as a result, the cosmetics were generally used. It has been found that when a fragrance modifier is used to suppress scent formation and to make it mild, a combustion type scent composition having satisfactory scent quality, strength and spread can be obtained. . That is, in the present invention, a fragrance adjusting agent, which has a strong tendency to be used as a component that suppresses fragrance in conventional cosmetics and the like, is used as a component that promotes the development of fragrance.

[0010] The amount of the above-mentioned perfume modifier is 20% or more by weight to the above-mentioned perfume in the present combustion type fragrance composition, preferably more than 30% by weight to the above-mentioned perfume, more preferably the above-mentioned perfume. To 50% or more by weight. As described above, in general, a fragrance control agent is generally used when suppressing fragrance in cosmetics and the like, and making the fragrance control mild, and since a fragrance control agent is used from a completely different viewpoint, for example, 20%, preferably Is 30
%, More preferably 50%, and the content thereof is quite different. Here, what should be considered heretofore is that a desired amount of a fragrance modifier has been added to cosmetics or the like in order to suppress the scent, whereas in the present invention, a scent when a composition such as incense burns is generated. It is a point which suggests the ratio of the perfume modifier which is preferable for accelerating.

[0011] The fragrance controlling agent to be blended in the combustion-type scent composition of the present invention includes tetrahydromethyl aviate,
Dihydromethyl aviate, triethyl citrate,
It is preferable to select from the group consisting of dipropylene glycol, isopropyl myristate, and a mixture of two or more of these. In particular, among these flavor control agents, a mixture of tetrahydromethyl aviate and dihydromethyl aviate exhibits a very excellent fragrance control function.

Further, as other perfume modifiers that can be employed,
Trialkyl citrate (ester), citrate, isooctanoate, alkyl isooctanoate (ester), dialkyl phthalate, phthalate, alkyl palmitate, palmitate, dialkyl adipate (Esters), adipates, propylene glycol dibenzoate,
Examples include polyoxypropylene (20) methyl glucoside, glucose derivatives and the like.

The burning scent composition of the present invention can be embodied as a candle or incense.

[0014]

Next, an embodiment of the present invention will be described. As a result of intensive studies by the present inventors, the present invention includes a combustible base and a fragrance, and in a combustion-type fragrance composition that promotes the generation of a fragrance by burning, a fragrance adjusting agent that adjusts the generated scent. By blending, the scent improves the quality, strength and diffusivity level in any case, and by adjusting the fragrance modifier to a predetermined amount, the scent quality, strength and diffusivity are all increased. The present inventors have found that a satisfactory combustion-type scent composition can be formed, and have been made based on the results.

The present fragrance modifier is a group of compounds generally used together with a fragrance when it is desired to suppress the appearance of the fragrance of the fragrance, to make the fragrance mild, and to increase the residual scent. , And is often used together with a fragrance when producing an fragrance as a part of the fragrance. However, in the combustion-type scent composition of the present invention, the fragrance modifier is used from a viewpoint different from the conventional ones. Determined. At first glance, it looks like a usage that contradicts the properties possessed by the original fragrance modifier, but surprisingly, in the combustion type scent composition of the present invention, the increase in scent intensity and the spread of scent are caused by an increase in scent. Is realized while maintaining the quality of the satisfactorily.

That is, the fragrance control agent is originally intended to suppress the appearance of the fragrance of the fragrance and to make the fragrance mild. However, the present inventors have found that, on the other hand, when used in a combustion-type scent composition, they exhibit a new function of increasing the intensity and spread of the scent. Here, the blending amount of the flavoring agent is 2% by weight relative to the flavoring agent blended together.
Desirably, it is 0% or more. If the ratio is less than this, the effect may not be sufficiently exhibited.

Further, it is preferable to further increase the content to 30% or more from the viewpoint of obtaining a certain effect. Further, when the content is 50% or more, a very excellent property of increasing the intensity of the scent and increasing the spread of the scent can be obtained, which is particularly desirable.
In addition, about the upper limit of the compounding quantity of a fragrance | flavor control agent, although it is not necessary to provide especially in order to implement | achieve the said characteristic, it takes the form of a candle and an incense stick which do not inhibit appropriate combustion in a combustion type scent composition, and later. In this case, it is preferable to suppress the required formability to such an extent that the required formability is not hindered.

Regarding the mechanism of developing characteristic characteristics in the combustion type scent composition of the present invention, the present inventors have concluded that, with respect to the specific fragrance volatilization promoting mechanism of combustion, a fragrance modifier is unique in the direction of increasing the intensity of scent. It is presumed that it has the auxiliary effect of. Compounds that can be used as a fragrance modifier in the combustion-type fragrance composition according to the present invention include tetrahydromethyl aviate, dihydromethyl aviate, triethyl citrate, dipropylene glycol, isopropyl myristate, and two or more of these. It can be selected from the group consisting of mixtures. here,
Particularly preferred as the fragrance control agent of the present invention is a mixture of tetrahydromethyl aviate and dihydromethyl aviate having good scent quality, satisfactory scent intensity and diffusibility.

The fragrance which can be used in the combustion type scent composition according to the present invention includes natural oils, synthetic fragrances,
All common flavors can be used, specifically, for example, all flavors such as floral, citrus, green, fruity, woody, musk, sipre, fuzea, and oriental. As the base, those conventionally used can be employed.

Further, specific examples of the combustion type scent composition according to the present invention that can be employed include incense sticks and candles. In that case, for example, if it takes the form of a candle, as a base constituting the burning type scent composition,
It may contain materials necessary for the construction of ordinary candles such as wax.
Even if a part contains a nonflammable material such as a metal or moisture in consideration of formability and the like, any material may be used as long as combustion can occur.
