Abstract

PURPOSE:To arbitrarily control the promotion or suppression of the volatile speed of a perfume, by arranging the perfume in a liquid or solid state in a container, which has a structure capable of volatilizing the perfume and steam to the outside, in such a state that the perfume is not directly brought into contact with water but can be brought into contact therewith in a steam state. CONSTITUTION:A perfume or water is infiltrated into a mat or put into a bag 2 composed of a liquid impermeable and gas permeable polymer membrane and arranged in a container 1 so as not to be brought into contact with the water or perfume in the container. As the liquid impermeable and gas permeable polymer membrane, a non-porous membrane having a thickness of 10-1,000mum composed of an ethylene/ethyl acrylate copolymer, vinyl acetate modified polyethylene, polyurethane, an ethylene/methacric acid copolymer (Zn-salt) or an ethylene/vinyl acetate copolymer is optimum.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a fragrance deodorant product, and more particularly to a fragrance deodorizer product in which the vapor pressure of water is used to control the volatilization rate of fragrance.

[Conventional technology and its problems]

BACKGROUND ART Air fresheners are used by consumers for the purpose of volatilizing fragrances, providing fragrance, and providing mental and physical comfort to people. Air freshener products include those made into a gel using polymeric compounds, liquid fragrances or fragrance solutions impregnated into bulb mats, etc., or those that are placed in a liquid reservoir and sucked up with a pulp core etc. and impregnated into pulp mats. There are some that allow you to do so. A fragrance is generally a mixture of two or more types of fragrances with different vapor pressures, but each fragrance has a different susceptibility, so the initial and post-oral fragrance notes are different. It is necessary to suppress this change in fragrance tone as much as possible, but with conventional types, it was extremely difficult to control the volatilization rate of the fragrance.

[Means for solving problems]

As a result of intensive research, the present inventors discovered that the rate of volatilization of fragrance can be easily controlled by generating water vapor within the fragrance container and creating an air flow within the container, and have completed the present invention. .

That is, in the present invention, the fragrance and the water in a liquid or solid state are arranged in a container having a structure that allows the vapor of the fragrance and water to evaporate to the outside, but not in direct contact with the water, but in a vaporized state. The present invention provides an air freshener deodorant product characterized by:

A container having a structure capable of volatilizing perfume and water vapor to the outside means a container having an opening or a vapor continuation opening using a liquid-impermeable, gas-permeable polymer thin film.

A state in which the fragrance and water do not come into direct contact means that the two are placed separately in a container so that they do not mix.

For example, you can put a partition in the container and put the fragrance on one side and water on the other, or you can impregnate the fragrance or water with a mat or put it in a bag made of a thin polymer membrane that is liquid-impermeable and gas-permeable, so that the two do not come into contact with each other. Refers to the state in which it is placed inside the container.

The state where the fragrance and water can come into contact in the form of steam means that there is a space within the container containing the fragrance and water.

It is preferable that the container has an opening because it is easier to freely control the volatilization rate of the fragrance. In other words, if the opening of the container is made relatively large, the rate of volatilization can be accelerated.Furthermore, the volatilization of fragrances varies depending on the surrounding humidity, and the amount of volatilization decreases at high temperatures. If placed in a suitable position, it will create a humidified state and suppress volatility.

Packing fragrances in a liquid or solution state in a bag made of a thin polymer membrane that is liquid-impermeable and gas-permeable prevents leakage even if the container is accidentally overturned, and also allows for a larger amount of fragrance to be placed than impregnated into a mat. This is desirable because it allows the use of

The liquid-impermeable, gas-permeable thin polymer film may include ethylene-ethyl acrylate copolymer having a film thickness of 10 to 1000 μm, vinyl acetate-modified polyethylene, polyurethane,
Non-porous thin films such as ethylene-methacrylic acid copolymer (Zn salt) and ethylene-vinyl acetate copolymer are most suitable.

〔Effect of the invention〕

The fragrance deodorizer product of the present invention can arbitrarily control acceleration or suppression of the volatilization rate of the fragrance.

In addition, with conventional fragrances using pulp mats, it was necessary to increase the surface area of the pulp mat and place it in a place with good air circulation in order to promote volatilization. Odor products are less subject to these restrictions and have a wider range of applications.

The volatilization control method used in the present invention has the advantage that it can also be applied to volatilization control of volatile organic compounds other than fragrances.

In addition, since fragrances and water do not come into direct contact, it is now possible to add deodorizers and deodorizers to water, which could not be used in conjunction with conventional fragrances due to the decomposition of fragrances and pigments, creating products that combine fragrance and deodorization. can also be applied.

〔Example〕

EXAMPLES The present invention will be explained in more detail with reference to Examples below, but the present invention is not limited to these Examples.

Example 1 (Effect of accelerating volatilization of fragrance) Eleven narrow-mouth polyethylene bottles 1 (caliber 4.5 mm) as shown in FIG.
4cm, height 1BCD+, bottom diameter 7c+s), 20% α-pinene, 20% limonene, 20% methyl benzoate
%, 20% acetophenone and 20% citronellal in a liquid-impermeable, gas-permeable film (copolymer of ethylene-ethyl acrylate +5
A bag 2 of 8cm x 8cm was hung at 10c+s from the mouth, 200 - of water 3 was put into the plastic bottle, and the volatility was checked at 40°C.

For comparison, volatility was also examined in the same manner except that no water was added.

The results are shown in Figure 2.

As is clear from Figure 2 (when water was added to the plastic bottle, almost all of the fragrance was lost after 6 days, whereas when there was no water, about 40% remained, indicating a remarkable effect of accelerating fragrance volatilization). It was done.

Example 2 (Effect of suppressing continuous loss of fragrance) Pulp mats 4 were spread on the bottoms (diameter 7 cm) of 11 polyethylene bottles 1 as shown in Fig. 3, and ventilation holes 5 were placed on the sides.
After opening 10 bags (1.5 x 2 cm), a liquid-impermeable gas-permeable film bag 2 containing 10 g of perfume was hung therein and the lid was placed in the same manner as in Example 1. The pulp mat 4 was allowed to absorb water at a rate of 20 mZ/day, and the fragrance volatility was observed at 25°C.

For comparison, volatility was also examined in the same manner except that water was not absorbed by the pulp cloak.

The results are shown in Figure 4.

As is clear from FIG. 4, when water was used, the losing streak rate was lower than that without water, and a remarkable effect of suppressing losing streaks was observed.
