CONSTITUTION: The hydrogel spray composition is characteristically composed of 0.3-6 wt.% of isobutylene maleic acid anhydride, 3-7 wt.% of C1-4 lower alcohol, 3-7 wt.% of fragrance, 0.5-5 wt.% of surfactant, and the balance of water.

Description

Aqueous gel sprayer composition

The present invention relates to an aqueous gel sprayer composition. More specifically, the present invention relates to an aqueous gel (hydrogel, water gel) spray comprising isobutylene maleic acid anhydride, a lower alcohol having 1 to 4 carbon atoms, a fragrance, a surfactant, and water as a gelling agent. It relates to a fish composition.

In the present application, a sprayer emits a natural or artificial fragrance in a certain space where a person can stay, for example, a toilet, a living room, a kitchen, and a warehouse, to induce a feeling or a natural feeling to a human being. As a product used to help life, its purpose is to mask and direct indoor odors.

The types of sprayers described above can be divided into pure and narrow sprayers whose main purpose is to give direction to air according to the definition, and broad deodorant products whose main purpose is to mask indoor odor. Products include deodorants that remove or mitigate odors by physical action, deodorants that remove or mitigate odors by chemical and biological actions, and deodorants that mask odors in other directions. In the commercially available products, various functions described above may be applied in combination.

Sprayers can be broadly classified into solid, liquid, and aerosol types according to the formulation of a carrier applied for releasing an active ingredient for aroma or deodorant, for example, a fragrance or deodorant.

First, in the case of solid sprayers, fibers such as felt, paper and cellulose beads, inorganic inorganic materials such as silica gel, florite, zeolite and ceramics, or ethylene vinyl acetate and absorbent Impregnated sprayers formed from resins such as water absorbent polymer beads, wax sprayers applying paraffin wax as a scented candle material, carrageenan, gellangum and agar And an aqueous gel sprayer formed of a gelling agent such as a gelling agent), and an oily gel sprayer formed of a gelling agent such as sodium stearate.

The gel sprayer encompassing the above-mentioned aqueous gel sprayer and oily gel sprayer is more specifically a product containing a liquid composition such as fragrance in a gel structure formed by using a gelling agent. It has a solid structure, but after exposure to air, the liquid component such as fragrance is volatilized, so that the initial solid structure cannot be maintained. Is formed. As such, the gel sprayer retracts as the liquid components such as fragrance, water, alcohol, and the like fly in contact with the air. If the gelling agent added to form the gel is aqueous, it is classified as an aqueous gel spray. Such an aqueous gel sprayer comprises a gelling agent polymer and its salts, scents, water, surfactants and other additives such as preservatives or cryoprotectants.

The gelling agent added to form such an aqueous gel sprayer includes carrageenan, gellan gum, and agar, as well as locust bean gum and synthetic carboxymethyl cellulose, which are usually sprayed as a powder at room temperature. It is usually added in the range of 1 to 10% by weight to other liquid compositions such as flavors, water, surfactants, preservatives and cryoprotectants. Depending on the type of gelling agent, but usually warmed to lukewarm or high temperature in the range of room temperature to 100 ℃ and dissolved for more than 5 minutes, and then adding a small amount of salts such as calcium chloride, potassium chloride and sodium chloride in less than 3% by weight, Lowering the temperature to room temperature yields the gelled contents. In this case, a fragrance component within 10% by weight can be generally applied. Since the fragrance is not dissolved in water in an aqueous gel, a method of forming or dissolving an emulsion with water is mainly applied using a nonionic surfactant.

In the case of the aqueous gel can be applied to the fragrance component within 10% by weight in general, compared to 30% by weight in the case of the oil-based gel to apply the sodium stearate aroma.

In the case of the conventional water-based gel sprayer, to give a pleasant and good feeling to a person by giving a direction in a place where there are many smells and smells, for example, a toilet or a basement room and a warehouse. To deodorize the odor. To this end, a suitable fragrance is selected to mask the odor but not to feel it, or to use a compound such as a plant extract to deodorize by acting on the structure of a specific molecule that makes a bad smell, such as a chemical reaction.

When the sprayer is classified according to the formulation of the substrate, the second type of liquid sprayer is a membrane sprayer, cellulose and polyethylene, which is volatilized through micropores of a film such as ethylene vinyl acetate or polyethylene. Liquid wick-type sprayer which volatilizes liquid such as fragrance, water, alcohol and surfactant through wick of fibrous material or porous ceramics such as this belongs.

In the case of the aerosol-type sprayer described above, the stock solution such as fragrance, water, alcohol, and surfactant is injected through the fine hole of the valve by using a propellant such as liquid propane gas and dimethyl ether. Solid and liquid sprayers are naturally volatilized, whereas aerosol sprays are user volatilized for a limited time and place.

The aerosol is a term referring to a colloidal state in which solid or liquid fine particles are dispersed in a physicochemical gas. The principle of the aerosol is to put a spraying agent such as gas and the contents to be sprayed in the pressure-resistant sealed container so that the contents are uniformly discharged or sprayed by the pressure of the spraying agent. For example, when 40 to 70% by weight of a liquefied gas is dissolved in a dissolved stock solution, it is sprayed into a mist, which is referred to as "spray," and the liquefied gas is poured into a stock solution in an emulsion state. When mixed with 15% by weight, the contents are discharged into a foam, which is called "bubble".

Looking at the composition of the aerosol product, the injection device consisting of a liquid, powder, and the like to be injected into the stock solution, liquefied gas or compressed gas (compressed gas), the injection device consisting of valves, buttons and dip tubes, and metal, glass or plastic material Consists of a pressure-resistant container consisting of. Looking at the process of discharging, the pressure inside the container is pressurized due to the pressure of the propellant, and when the button is pressed, the injector is opened, the contents and the propellant are injected, and when the button is released, the injector is closed to stop the injection.

There are two kinds of the propellant, liquefied gas and compressed gas. At room temperature, a gas that is easily liquefied as a gas and pressurized is called a liquefied gas.A stable pressure is obtained because liquid and gas coexist in a gas-tight container, and liquefied petroleum gas, dimethyl ether, and freon gas are applicable. do. Liquefied petroleum gas is a combustible gas having a low price and low odor, which is used by adjusting the pressure according to the proportion of lower hydrocarbons, propane, butane and pentane. Because of its high flammability, stability should be increased by adjusting the spray strength or spray volume. The characteristic of dimethyl ether is that it has good solubility in water and it is also flammable gas, so be careful about flammability like liquefied petroleum gas. Freon is a generic term for materials with low boiling point and composed of chlorine, fluorine, carbon and hydrogen, and has been widely used as a propellant for aerosol products because of its excellent safety, inertness and safety. It turns out to be cause and is banned all over the world. Gases that do not liquefy under normal temperature and low pressure, such as nitrogen gas and carbon dioxide gas, are called compressed gases. Gases packed in a compressed state in the container do not dissolve in the contents but apply pressure from the gas phase above the contents. Compared with liquefied gas, there are no problems of compatibility, reactivity and flammability, but the pressure in the container decreases with use, which causes the quality of the product to deteriorate.

When designing an aerosol sprayer as described above, Freon gas as a propellant is not used because the compressed gas is deteriorated due to the preservation of the global environment such as ozone layer destruction, air pollution and global warming. Gas or dimethyl ether should be used. Since liquefied petroleum gas or dimethyl ether is highly flammable, it is very dangerous when used in a narrow space such as near a fire or inside an automobile. Therefore, the development of a container using no gas is being actively pursued. Therefore, in particular, a product which is discharged in the mist form, a conventional sprayer that does not use gas is used a lot. A sprayer-type air freshener is preferred, in which the contents are raised from the inside of the container and sprayed in a desired direction through a minute hole by the action of pumping by the force of pressing a button with a human finger without using a propellant. It must be moved inside the container and sprayed out of the container, so it can contain only liquids that are sufficiently fluid. When the fluidity is low, the spray performance drops rapidly and eventually does not even discharge. do.

In the case of the above-mentioned sprayer-type fragrance, the container is composed of the upper injector and the container, and the content is contained in the form of a liquid liquid in the container. Since it flows to occupy the lowermost end of the container, there is a disadvantage that the content cannot be sprayed because the content cannot be supplied to the dip tube in which the inlet is placed at the bottom of the container to flow the content to the upper injector. In this case, it is inconvenient to use because the container can only be used upright.

An object of the present invention is to use a small amount of isobutylene maleic anhydride excellent in gel formation as a gelling agent to form a sprayer composition in the form of a gel with a low fluidity and a suitable cohesive force to be discharged even when the container is tilted 90 degrees The present invention provides an aqueous gel sprayer having excellent discharge property and spray property, which are sprayed in a particulate form during discharge.

The aqueous gel sprayer composition according to the present invention comprises 0.3 to 6% by weight of isobutylene maleic anhydride as a gelling agent, 3 to 7% by weight of lower alcohols having 1 to 4 carbon atoms, 3 to 7% by weight of fragrances, and 0.5 to 5 surfactants. It is characterized by comprising water as weight percent and residual amount.

The aqueous gel sprayer according to the present invention is characterized in that the aqueous gel sprayer composition is applied to a sprayer type container.

Hereinafter, specific embodiments of the present invention will be described in detail.

The aqueous gel sprayer composition according to the present invention is an aqueous gel sprayer composition comprising a gelling agent, water, a surfactant, and a perfume, and contains isobutylene maleic anhydride as the gelling agent.

In the present invention, isobutylene maleic anhydride synthetic polymer was applied to KI-Gel 201K manufactured by Kuraray, Japan. It is a white powder of 20 mesh or less, which is 30 seconds when water is absorbed at 0 to 100 ° C. under pH 4 to 11 at room temperature. Thereafter, the water can absorb about 200 times by weight and is characterized by not being separated from the water after absorption. The aqueous gel sprayer composition of the present invention is formed into a gel phase with low fluidity and adequate cohesion by using isobutylene maleic anhydride excellent in gel formation even in a small amount as a gelling agent.

The content of the isobutylene maleic anhydride is 0.3 to less than 6% by weight. When isobutylene maleic anhydride is included in less than 0.3% by weight, the entire composition cannot be gelled sufficiently, and when used in an amount of 6% by weight or more, the composition is strongly coagulated, thus forming a hard gel having no fluidity, thus adversely affecting dischargeability and sprayability. Can have

The aqueous gel sprayer according to the present invention is obtained by applying the above-mentioned aqueous gel sprayer composition to a sprayer type container.

Applying the above aqueous gel sprayer composition formed in a gel form with low fluidity and appropriate cohesion by using isobutylene maleic anhydride to the sprayer type container, the contents do not flow by gravity even if the container is tilted more than 90 degrees. It is possible to provide an aqueous gel sprayer that can flow through a deep tube located at the bottom of the container by a pumping action by a valve and a nozzle device and be sprayed in the form of fine particulate matter upon discharge.

Hereinafter, preferred embodiments and comparative examples of the present invention will be described.

The following examples are intended to illustrate the invention and should not be understood as limiting the scope of the invention.

In addition, the aqueous gel sprayer composition prepared as described above was applied to a sprayer-type container to prepare an aqueous gel sprayer.

Experimental Example 1

Appearance Evaluation Experiment

The aqueous gel sprayer compositions prepared in Examples and Comparative Examples were first visually observed, and when there was fluidity, viscosity was measured. The LVT model serial number 87300 from Brookfield Viscometer was used to spin the spindle at spindle number 3 at 25 ° C. for at least 30 seconds until the viscosity was sufficiently stabilized and unchanged. In order to give a simple meaning to the measured values, the gel which becomes solid with little fluidity due to gravity and cannot be measured is a hard gel, and has a slight fluidity due to gravity with a viscosity of 10,000 cps or more. Soft gel, hard viscosity when viscosity is above 2,000 cps and below 10,000 cps, hard sol, viscous fluidity due to gravity Are expressed as soft sol. The results are shown in Table 7.

Experimental Example 2

Dischargeability Evaluation Experiment

Dischargeability was measured for the spray-type aqueous gel sprayers prepared in the above Examples and Comparative Examples. When the contents came out by pressing a button, it was regarded as discharge property, and it was divided and displayed in three stages when discharge property was good, when it was normal and when it was not good. The results are shown in Table 7.

Experimental Example 3

Spray evaluation test

Sprayability was measured for the aqueous gel sprayers prepared in the above Examples and Comparative Examples. The shape which was sprayed by pressing a button was seen, and it divided into five steps, when spray property is very good, good case, a little good case, normal case, and bad case. The results are shown in Table 7.

As shown in Table 7, except for Comparative Example 1, which formed a hard gel, Comparative Examples 2 to 13 were inefficient in gel formation because a large amount of gelling agent was required to form the gel. In the case of Comparative Example 1, in order to dissolve the carrageenan, the mixture was heated to 70 ° C., all the raw materials were added and stirred, and then slowly gelled while the temperature was lowered to 50 ° C. or lower, thereby forming a hard gel having no fluidity at room temperature. When the contents were put in the sprayer at a high temperature, cooled to room temperature, and sprayed after gelling, the contents were not discharged and spraying was impossible. Comparative Examples 2 to 13 formed a soft sol, hard sol or soft gel, requiring more gelling agent to form a high viscosity gel. In the case of the xanthan gums of Comparative Examples 2 and 3 and the locust bean gums of Comparative Examples 4 and 5, 0.5 to 2% by weight of a gelling agent was required to form a gel sufficiently, and the agar of Comparative Examples 6 to 9 and Comparative Examples 10 to 13 For the carboxy methyl cellulose of 2 to 5% by weight of gelling agent was required. As the xanthan gum and locust bean gum increased the gelling agent, the dischargeability worsened and the contents were discharged in both sol and gel states, but not sprayed. Agar and carboxy methyl cellulose increased the amount of gelling agent required for gelation compared to xanthan gum and locust bean gum, and these also resulted in poor dischargeability with increasing gelling agent, and the contents were discharged in both sol and gel states. It did not spray.

Examples 1 to 5 using isobutylene maleic anhydride as the gelling agent of the present invention gelled sufficiently at 0.5% by weight to form a gel in a small amount, it can be seen that efficient gel formation compared to Comparative Examples 2 to 13. . In addition, as the amount of the gelling agent increased, the dischargeability was somewhat lowered, but it was sufficiently sprayed when discharged. It was observed that the contents formed in the soft gel form with less fluidity in the container were sprayed in the form of fine particles when discharged out of the container.

Accordingly, the present invention provides an aqueous gel sprayer having excellent flowability and sprayability, which is capable of discharging even when the container is inclined at least 90 degrees by forming a gel having low fluidity and adequate cohesion, and which is sprayed in the form of fine particles when discharging. There is.

Although the present invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications and variations are possible within the technical scope of the present invention, and such modifications and modifications are within the scope of the appended claims.
