Description

The present invention relates to a gel-like composition having high heat resistance and high transparency used for an air freshener for automobiles.

There are various forms of fragrances used for automobiles, such as liquids, gels, and solids. Among them, those filled with a gel-like composition are popular because they are difficult to spill and are often required to have a transparent feeling like transparent water from the design of the fragrance.

In order to commercialize the fragrance filled with the gel composition as described above, various proposals using gellan gum which is relatively excellent in transparency among gelling agents have been made. For example, JP-A-01-074239 discloses a transparent gel composition containing a volatile substance, gellan gum, and a surfactant capable of solubilizing the volatile substance. Japanese Patent Application Laid-Open No. 2007-029175 discloses a transparent or semi-transparent material comprising a divalent metal salt of polyoxyethylene alkyl ether sulfate, a nonionic surfactant having HLB of 10 to 16, gellan gum, and a fragrance. A transparent gel fragrance composition is disclosed. JP-A-2005-287570 discloses a long-term fluorescence emission and aroma deodorizing action in an aqueous system by blending a specific phosphorescent pigment and an amine oxide type amphoteric surfactant, and An aqueous fluorescent aroma deodorant composition excellent in stability and aroma deodorizing action is disclosed.

In addition, examples of gelling agents that can be generally used in fragrances include carrageenan, agar, and gelatin. These gelling agents have sufficient transparency but not sufficient heat resistance. When this gelling agent is used as a fragrance for automobiles, the atmosphere temperature of automobiles parked under hot weather in summer may exceed 90 ° C., so that the gel is dissolved.

In order to eliminate the above-mentioned drawbacks and improve heat resistance, a gelling agent made of gellan gum is sometimes cross-linked with calcium. However, although heat resistance is sufficient, there is a drawback of low transparency.

The reason why the transparency of the gelling agent composed of gellan gum is crosslinked with calcium is due to the amount of gellan gum and calcium added. When the heat resistance is to be imparted, the amount added increases and turbidity occurs. Therefore, if the amount of gellan gum and calcium added is kept in a range that is not cloudy in order to maintain transparency, there is a drawback that the heat resistance becomes insufficient. Therefore, the fragrance for automobiles filled with the gel composition of the prior art has not been sufficiently satisfactory in terms of achieving both gel transparency and heat resistance.

Japanese Patent Laid-Open No. 01-074239 JP 2007-029175 A JP 2005-287570 A

An object of the gel-like fragrance composition of the present invention is to provide a gel-like composition having heat resistance and high transparency that can be used as a fragrance for automobiles.

The gel-like fragrance composition of the present invention is added with a gelling agent composed of gellan gum, a crosslinking agent composed of calcium, and 3-methyl-3-methoxy-1-butanol (MMB).

Furthermore, the blending amount of the gellan gum is preferably in the range of 0.2% to 2.0%.

Furthermore, the said calcium consists of calcium lactate, and it is good in the compounding quantity of the said calcium lactate being in the range of 0.002%-0.04%.

Furthermore, the blending amount of the 3-methyl-3-methoxy-1-butanol (MMB) is preferably 3% or more.

The gel-like fragrance composition of the present invention realizes a gel-like composition having high transparency and heat resistance by adding 3-methyl-3-methoxy-1-butanol (MMB) together with gellan gum and calcium lactate can do.

The gel-like fragrance composition of the present invention comprises gelling gum, calcium (calcium lactate) and 3-methyl-3-methoxy-1-butanol (MMB) added gelling agent, crosslinking agent, solvent, fragrance, and surfactant. The gellan gum, which is a gelling agent in the gel-like fragrance composition, is blended in an amount of 0.2% to 2.0%, preferably 0.4% to 0.00. 8% is recommended.

When the blending amount of gellan gum is less than 0.2%, the heat resistance is not sufficient, and when heated, it dissolves, and when it is more than 2.0%, the transparency is lowered and turbidity appears.

  The crosslinking agent used in the present invention is calcium, and calcium chloride, calcium lactate and the like can be used. The blending amount of calcium lactate is 0.002% to 0.04%, preferably 0.006% to 0.02%.

In addition, when it is less than 0.002%, the heat resistance is not sufficient, and when heated, it dissolves. When it is more than 0.04%, the transparency is lowered and turbidity appears.

  Further, the blending amount of 3-methyl-3-methoxy-1-butanol (MMB) used in the present invention is 3% or more, preferably 5% to 10%.

When the amount is less than 3%, the heat resistance is not sufficient, and when heated, it dissolves. Moreover, even if it is added in a large amount, there is no effect on the transparency, but if it is added in an amount of 10% or more, the heat resistance is not effective and the cost is increased, resulting in increased waste.
