Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gel-like aroma composition, more particularly a 3-methyl-
The present invention relates to a gel fragrance composition containing 3-methoxybutanol as a fragrance volatilization regulator.

Conventionally, gel fragrances using water as a carrier have been known, and examples of gelling agents include carrageenan, agar,
There are locust bean gums, etc., and examples of thickeners include carboxymethyl cellulose.

It has been disclosed that a water gel composition suitable for use can be prepared by blending hydroxy lower alkyl cellulose, methyl cellulose, water-soluble polyethylene oxide, starch glycolate, etc. in specific proportions (U.S. Patent No. 2).
, No. 927.055 1% Kosho 47 = 36630). However, when a fragrance is added to a gel-like composition having such a formulation, it is extremely difficult to maintain a constant balance in the fragrance tone over a long period of time and to provide it with diffusibility and sustainability. The reason for this is that water, which has a high volatilization rate, is used as a carrier, so low boiling point perfume ingredients volatilize with water, changing the perfume composition.
It is said that this is because the balance of fragrance is disrupted. As a result of intensive studies to overcome these defects, the inventors of the present invention found that 3-
It has been found that by blending methyl-3-methoxybutanol into a gel composition as a fragrance volatilization regulator, it is possible to maintain a certain balance in the fragrance tone over a long period of time, and to impart diffusibility and sustainability.

The gel-like aroma composition of the present invention contains 3-methyl-3-methoxybutanol 5-30% by weight, a gelling agent 0.5-5% by weight, an emulsifier 0.1-5% by weight, 6 water 60-90% by weight, and Contains 1 to 20 parts by weight of fragrance.

3-Methyl-3-methoxybutanol used in the present invention has a flash point (71°C) and an ignition point (395°C) as an organic solvent.
) and extremely low toxicity (LD505.838/#). In addition, it has 'I mold, which is highly compatible with water, has appropriate volatility, and has a light odor, which makes it very suitable as a fragrance volatilization regulator for indoor air fresheners.

In the present invention, 3-methyl-3-methoxybutanol is used in the gel aroma composition in a range of 5 to 30% by weight, but if it is less than 5% by weight, the fragrance is adjusted for volatilization. It has little effect as an agent, and if it exceeds 30 weight sl, a stable gel cannot be obtained, so it must be used within the above range.

According to the present invention, for example, carrageenan, agar, locust bean gum, etc. can be used as the gelling agent, and the blending ratio thereof is in the range of 0.5 to 5% by weight. If the amount of gelling agent is less than 0.5 weight s4, the aroma composition will not gel easily, while if it exceeds 5 weight, it will be difficult to dissolve the gelling agent and the aroma composition will be too hard, which is not preferable. .

Emulsifiers are also used to disperse and bind fragrances in aqueous media. Suitable emulsifiers include, for example, polyoxyethylene hydrogenated castor oil, polyoxyethylene alkylphenyl ether, polyoxyethylene alkyl ether,
Nonionic surfactants such as polyoxyethylene sorbitan fatty acid ester, polyoxyethylene stearate, and chrycerol fatty acid ester can be used, and their proportion in the gel composition is 0.1 to 1□51% by weight? 'Suitable. If the amount of emulsifier is less than 0.1 weight, the fragrance composition will not be suitable. In addition, colorants, preservatives, etc. can be blended in any proportion as necessary.

The amount of water added to the aromatic composition is 60 to 900 to 90% by weight.If the amount of water is less than 60*amount, the components that are difficult to gel are likely to separate.

On the other hand, it is difficult to add water in excess of 96 tons by weight due to the proportions of other components.

The fragrance is used in a range of 0.5 to 20% by weight. If it is less than 0.5 weight, it will not be possible to obtain a suitable fragrance, while if it is used in excess of 20 weight, the effect will not be so great.

Examples of formulations of blended fragrances that can be preferably used as the fragrance component of the gel fragrance composition of the present invention are as follows.
