 Oily gel fragrance composition {AROMATIC COMPOSITION OF OIL GEL FORMULATION}

[TECHNICAL FIELD OF THE INVENTION]

The present invention relates to an oily gel fragrance composition, and more particularly to a fragrance composition having excellent aroma persistence, thermal stability, transparency and decorative properties, and having an aromatherapy effect.

[Private Technology]

In the past, fragrances were only a way of masking with other substances that were stronger than bad smell sources. However, in the 80's, the demand for air fresheners with a pleasant odor while reducing odor itself has increased, and the development of air fresheners for cigarettes, pets, and human own odors that are not currently considered to be removed is required. In particular, as the fragrance therapy has received new attention, various perfume substances have been developed and applied to all industries, such as cosmetics, household goods and medicines. However, the fragrance material has a disadvantage that it is difficult to maintain the fragrance for a long time in the natural state easily volatilized, there is a problem that the strength of the fragrance is reduced due to the emulsifier (solubilizing agent) commonly used for transparency.

The most common form of fragrance is in the form of a gel in which the fragrance material is solidified in a container and volatilized. Gel fragrances are prepared using a gelling agent such as carrageenan, agar and gelatin, gellan gum and the like, which is formed into a gel that forms a network while being hydrated by dispersing and heating in water and then densely arranged by cooling. Each of the gelling agents are used alone, and if additional components are included, a qualitative deterioration may be caused. For example, when the gel contains an insoluble compound such as a fragrance, the gel may not be uniformly formed, which may cause cracking and non-coagulation of the gel, and when the surfactant contains a very hydrophilic surfactant or the like, the gel may be solidified. The reaction may not be carried out. In addition, when the volatile material is included, the structure of the gel may become unstable due to the nonvolatile residue remaining after the volatile material is consumed.

Efforts have been made to solve these problems and develop gels that can be applied universally, and various methods have been proposed. As an example, Japanese Laid-Open Patent Publication No. 1989-297484 discloses a method for producing an aqueous gel having improved thermal stability and transparency by mixing a gelatin gelling agent with a crosslinking agent such as an olefin maleic anhydride copolymer. However, the volatile components included in the gel is volatilized, so that the appearance of the appearance collapses when the gel shrinks, the decoration is greatly reduced, there is a problem of low stability at a temperature below 0 ℃.

In addition, oily gels have been developed that do not contain water-soluble formulations. The oily gel has excellent thermal stability, and maintains the appearance of the gel as it shrinks. The manufacturing method of an oily gel is described in Unexamined-Japanese-Patent No. 61-12613 as an example. The patent proposes a fragrance composition consisting of hydrocarboxylic acid, paraffin and oily perfume, but the fragrance lasting effect has not been improved.

On the other hand, jelly (gel) type perfume composition is divided into aqueous and oily. Aqueous type uses water as a base, so the fragrance of incense is quick and it has the disadvantage of flying faster in summer. Therefore, the volume should be increased to compensate for the above disadvantages. The oily type uses oily oil as a base to keep the fragrance for a long time, and to allow you to feel the soft fragrance slowly and comfortably. However, it is difficult to formulate, the manufacturing process is difficult, it is very difficult to commercialize the gel type. In particular, when using a natural herbal oil as a fragrance material, when prepared with an aqueous gel is not good thermal stability, the oil-based gel using the conventional limonene has a limit of odorant species.

Accordingly, an object of the present invention is to provide an oily gel fragrance composition comprising natural herbal oil as a fragrance material.

It is another object of the present invention to provide an oily gel fragrance composition having excellent stability and improved fragrance lasting effect.

In order to achieve the above object, the present invention provides an oil-based gel comprising 0.01 to 70% by weight of herbal oil, 0.01 to 20% by weight of higher fatty acid having 12 to 24 carbon atoms, 20 to 95% by weight of isoparaffin and 0.1 to 20% by weight of fatty acid metal salt. A perfume composition is provided.

The present invention also provides a volatilizer filled with the oily gel fragrance composition.

Hereinafter, the present invention will be described in detail.

The present invention relates to an oily gel fragrance composition, wherein the composition comprises a fragrance, an emulsifier, a solvent and a gelling agent.

The fragrance may be conventional fragrance fragrances or herbal oils, preferably herbal oils. The conventional fragrance fragrances may be water insoluble and may be any commercially available one. For example, it may be a floral flavor or citrus flavor, but is not limited thereto. The herbal oil is an essential oil extracted from a conventional essential oil extraction method from herbs, for example, rosemary, lime, eucalyptus, lavender, peppermint, pine needles, sandalwood, bergamot, beige, myrtle, inula, jasmine, lemon, orange It may be, but is not limited to, oils extracted from chamomile, Frankensense, ylang-ylang and basil. The amount of fragrance may be 0.01 to 70% by weight in the oily gel fragrance composition. If the content of the fragrance is less than 0.001% by weight, the aroma effect may be insignificant, and when it exceeds 70% by weight, it may be difficult to realize a subtle scent and may be uneconomical. In addition, the fragrance may include at least one herbal oil, but may further include a conventional fragrance, deodorant or antibacterial agent. At this time, the content of the herbal oil in the fragrance may be 0.001 to 95% by weight, and includes a fragrance fragrance, deodorant or antimicrobial agent as a residual amount. The fragrance for the fragrance is preferably included up to 5% by weight or less. If the content of the fragrance perfume exceeds 5% by weight, the amount of the solvent used may increase, which may adversely affect the gel quality, such as gel strength.

The emulsifier of the present invention is used for the purpose of solubilizing the fragrance, and may be a conventional solubilizer. Emulsifiers may include higher fatty acids, such as fatty acids having a single or one or more double bonds having 12 to 24 carbon atoms. The higher fatty acid may be selected from the group consisting of lauric acid, myristic acid, stearic acid, oleic acid, linoleic acid and mixtures thereof, but is not limited thereto. Preferably the emulsifier is oleic acid or a mixture of oleic acid and linoleic acid. The oleic acid and lenoleic acid mixture is 1: 9 to 9: 1 weight ratio. Emulsifiers may be included in the oily gel fragrance composition in an amount of 0.01 to 20% by weight, preferably 0.5 to 10% by weight. If the content of the emulsifier is less than 0.01% by weight, the gelling agent does not dissolve at room temperature, so warming is required at 60 degrees or higher, and the gel strength may be lowered when the content of the emulsifier exceeds 20% by weight.

The solvent of the present invention may be an isoparaffinic compound in order to appropriately control the volatility of the perfume. Isoparaffin may be isoparaffin having 5 to 20 carbon atoms, preferably isoparaffin having a BP (Boiling Point) of 100 to 350 ℃, the pour point is -70 ℃ or less. Examples of isoparaffin include isoparaffins C, E, G, H, L, M and V of Exxon, which is a saturated hydrocarbon having 7 to 14 carbon atoms, but is not limited thereto. The isoparaffin may be used alone or in combination of two or more thereof. The solvent may be included in the oil gel fragrance composition in 10 to 95% by weight, preferably 30 to 80% by weight.

The gelling agent of the present invention may be a fatty acid metal salt. The fatty acid metal salt may be selected from one or more selected from the group consisting of aluminum octylate, calcium octylate, sodium octylate, and aluminum hexanoate, but is not limited thereto. Preferably, aluminum hexanoate is used as the gelling agent. The gelling agent may be included in the oily gel fragrance composition at 0.1 to 20% by weight, preferably 0.5 to 5% by weight. If the content of the gelling agent is less than 0.1% by weight, phase separation may not occur and gelation may occur. If the content of the gelling agent exceeds 20% by weight, the gel strength may be too high, which may cause difficulty in manufacturing.

In addition, the present invention relates to a method for producing an oily gel fragrance composition,

(a) mixing and stirring a solvent and a gelling agent;

(b) adding fragrance to the mixture (a) and stirring the mixture;

(c) adding and stirring an emulsifier to the mixture of step (c); And

(d) standing and gelling.

Step (a) to (d) may be carried out at room temperature, such as 15 to 30 ℃, each stirring time may be 1 minute to 1 hour. If the reaction temperature is lower than 15 ℃ can be phase separated, if higher than 30 ℃ gelation proceeds quickly it may be difficult to produce the product.

In the step (d), bubbles are generated inside the oil gel, and gelation is performed before bubbles are released to the outside. Thus, the final oily gel contains bubbles therein. The bubbles naturally deflate, but can be removed using a defoaming device or the like. In addition, gelation can be carried out in various types of containers to prepare various types of perfume composition prepared according to the shape of the container. At this time, the prepared gel does not stick easily upon shrinkage, and thus shows a clean appearance.

The oily gel fragrance composition prepared by the method according to the present invention not only has excellent volatility, transparency and strength, but also can be manufactured in various forms and has excellent decorative properties.

The oily gel fragrance composition according to the present invention can be used for the purpose of removing odor or releasing aromatic fragrance indoors or outdoors, and can be used by a method using natural volatilization or using a volatilizer.

The method by natural volatilization has the advantage that the fragrance is softly divergent, there is a difference in the amount of volatilization by the temperature of the atmosphere, etc., there is a disadvantage that the volatilization rate is slow. The method using the volatilizer is a method using heat or wind, the method of using heat is good to use the volatilizer attached to the fan because there is a drawback of a lot of electricity consumption. That is, it is possible to volatilize the fragrance by convection of air with a volcanic fan having a siko sphere or turbine type, and in this case, the amount of volatilization can be adjusted, the volatilization speed is high, and the use is very convenient.

Hereinafter, examples of the present invention will be described. The following examples are only for illustrating the present invention and the present invention is not limited to the following examples.
