Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to an aerosol-type cleaning composition, and more particularly, to an aerosol-type cleaning composition that can be suitably used for cleaning dirt attached to kitchens, bathrooms, toilets, and other rooms. It is about things.

[0002]

2. Description of the Related Art In a room such as a kitchen, cooking oil or the like adheres to the periphery of a range, a wall, a window, and a ventilation fan when cooking, and this gradually deteriorates with the passage of time. Become. Further, even in a room other than the kitchen, tobacco smoke and the like may adhere to walls and furniture, and dark stains may adhere. Conventionally, a trigger spray type detergent and an aerosol type detergent composition (JP-A-64-69699) have been used for such stains.

[0003] The trigger spray type cleaning agent is mainly composed of water and a surfactant. However, since it is a pump type, there is a high possibility that mist is scattered and sucked, and the dripping of a jet is also caused. However, there is a problem that extra wiping work is required. Furthermore, there is also a problem that hands are easily roughened due to strong alkalinity for countermeasures against oil stains, and that it is necessary to wipe off water to remove the adhered oil film.

On the other hand, an aerosol-type cleaning composition described in Japanese Patent Application Laid-Open No. 64-69699 is composed of an aqueous stock solution containing d-limonene and a surfactant and a liquefied petroleum gas (LP).
G). According to this, although the propellant is foamed, the rebound during spraying is large,
In addition, since fine foam mist is scattered, there is a problem that the mist is likely to be sucked. In addition, since a large amount of the ejected matter adheres to the spray button in the form of a foam after spraying, there is also a problem that it is necessary to clean the ejection port portion of the button each time spraying is performed.

[0005]

Accordingly, the present invention provides
The present invention has been made in view of the above-described conventional problems, and its purpose is to prevent mist generation during spraying,
An object of the present invention is to provide an aerosol-type cleaning composition which does not have a dripping of a spray liquid, does not require an extra wiping operation, and has no spray foam attached to an injection port portion.

[0006]

That is, according to the present invention, a stock solution containing d-limonene, water and a surfactant, liquefied petroleum gas (LPG) and dimethyl ether (DM)
An aerosol-type cleaning composition comprising the mixture of E) is provided. In the present invention, LPG and DM
The mixture of E is preferably contained in an amount of 5 to 45% by weight, and as a mixing ratio, LPG / DME (weight ratio) is preferably 10/90 to 90/10.
As the surfactant, a nonionic surfactant is desirable.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail. The aerosol-type cleaning composition of the present invention contains a stock solution containing d-limonene, water and a surfactant, and a mixture of liquefied petroleum gas (LPG) and dimethyl ether (DME).

[0008] d-limonene is a compound represented by the following formula, and is a substance that is responsible for the cleaning action of the aerosol-type cleaning composition of the present invention. The amount of d-limonene is 5 to 70% by weight based on the whole aerosol-type cleaning composition.
Is preferable, and 10 to 60% by weight is more preferable. If the amount of d-limonene is less than 5% by weight, sufficient detergency cannot be obtained, while if it exceeds 70% by weight, there is no further improvement in detergency and the cost is increased.

The surfactant has an effect of emulsifying d-limonene and improving wiping properties. Examples of such a surfactant include anionic surfactants such as sulfonate and phosphate surfactants, nonionic surfactants, amphoteric surfactants, and cationic surfactants. Examples of the sulfonate-based anionic surfactants include, for example, long-chain (C ₃ -C ₂₂ ) alkyl sulfonates, and examples of the phosphate-based anionic surfactants include long-chain monoalkyl, dialkyl, and sesquialkyl. (C ₃ -C ₂₂ ) phosphate and the like. Examples of the nonionic surfactant include polyoxyethylene long-chain alkyl (C ₃ -C ₂₂ ) ether and polyoxyethylene polyoxypropylene block polymer. As the amphoteric surfactant,
Examples thereof include amino acid-type amphoteric surfactants and betaine-type amphoteric surfactants such as betaine alkyl acetate. Furthermore, examples of the cationic surfactant include an aliphatic amine salt and a benzalkonium salt. Among them, nonionic surfactants are preferred from the viewpoints of emulsion stability to d-limonene, foaming properties, and wiping properties after washing.

The amount of the surfactant is preferably 0.1 to 10% by weight, more preferably 0.5 to 5% by weight, based on the whole aerosol-type cleaning composition. If the amount of the surfactant is less than 0.1% by weight, d-limonene is not sufficiently emulsified, while if it exceeds 10% by weight, no further improvement in the emulsifying effect of d-limonene is observed. On the contrary, the wiping performance is reduced.

[0011] Water is added to the above-mentioned d-limonene and surfactant to form a stock solution. The amount of water is preferably 10 to 85% by weight based on the whole aerosol-type cleaning composition, and 20% by weight. ~ 80 wt% is more preferred. As the water, purified water or pure water is preferably used, but it is not limited thereto.

[0012] An arbitrary component can be further added to the stock solution. Examples of the optional component include a lower alcohol, BHT, an abrasive, a bactericide, a preservative, a viscosity modifier, a pigment, a fragrance, and the like.

The aerosol-type cleaning composition of the present invention comprises:
It can be prepared by including a mixture of liquefied petroleum gas (LPG) and dimethyl ether (DME) (hereinafter, referred to as an LPG / DME mixture) in the stock solution. LPG / DM in aerosol-type cleaning composition
The mixture ratio of the E mixture is preferably 5 to 45% by weight,
0 to 40% by weight is more preferred. If the blending ratio of the LPG / DME mixture exceeds 45% by weight, the momentum of the ejected material is too strong and the amount of scatter is large, which is not practical. On the other hand, LPG /
When the blending ratio of the DME mixture is less than 5% by weight, the injection amount decreases, and the foaming property decreases. In addition, the spray nozzle portion tends to be stained with the foam, which is not preferable.

The mixing ratio in the LPG / DME mixture is LPG / DME (weight ratio)
Is preferably 10/90 to 90/10, and 15
/ 85 to 85/15 is more preferable. As described above, by using a mixture of LPG and DME in a predetermined range, a foam-like jet can be accurately jetted to the cleaning portion. Further, since there is almost no generation of mist at the time of spraying, it is possible to minimize the risk of inhaling the medicine. Furthermore, since there is no dripping of the spray liquid, no extra wiping work is required, and further, there is no need to perform a final wiping operation when wiping.
Furthermore, since there is no adhesion of the spray foam to the injection port portion of the aerosol, the spray can always be sprayed in a good state.

[0015]

Hereinafter, the present invention will be described in detail with reference to examples. (Examples 1-3, Comparative Examples 1-2) A detergent composition was prepared using a stock solution and a propellant having the following compositions. (Stock solution formulation) d-limonene 28.5 wt% nonionic surfactant 1.5 wt% isostearic acid 0.8 wt% morpholine 0.5 wt% purified water 68.7 wt% Emarex SEL-80 (trademark) (manufactured by Nippon Emulsion) was used as the nonionic surfactant.

As the propellant, LPG alone or DME alone was used, and the mixing ratio (weight ratio) of LPG and DME was changed as shown in Table 1. The mixing ratio between the stock solution and the propellant was 81.9: 18.1 (weight ratio).

Next, the cleaning composition prepared as described above was filled in an aerosol can to prepare an aerosol-type cleaning composition. This aerosol-type cleaning composition was sprayed onto a vertical glass surface from a distance of 15 cm to check the state of the jet. Table 1 shows the results.

[0018]

[Table 1]

When spraying onto a vertical glass surface from a distance of 15 cm, a circular foam-like pattern was formed on the glass surface in each of Examples 1 to 3 and Comparative Examples 1 and 2. However, the time required for dripping (the time the foam is held in that position in its original shape)
It has been found that the composition varies greatly depending on the composition of the propellant. It was also found that the generation of mist and the stain on the spray injection port differed depending on the composition of the propellant. As is clear from the results in Table 1, the case of Example 3 was the best,
In the case of a detergent composition using a PG / DME mixture, L
It was overall better than the detergent compositions of PG alone and DME alone. The cleaning composition of Comparative Example 2 (DME
Alone) was the problem with the quickest dripping. By the way, with respect to the dripping, in the mixing ratio (weight ratio) of LPG and DME, the larger the LPG, the less prescription the dripping. However, the most favorable condition of the spray foam including the spray button without spoiling the nozzle of the spray button was a formulation containing a large amount of DME in the mixing ratio of LPG and DME.

[0020]

As described above, according to the aerosol-type cleaning composition of the present invention, a foam-like propellant can be accurately jetted onto a cleaning portion,
There is almost no mist generation at the time of spraying, and a remarkable effect of minimizing the risk of inhaling the medicine can be obtained.
Further, the aerosol-type cleaning composition of the present invention has an effect that there is almost no dripping of the spray liquid, so that wiping work is not required, and that there is no need to perform finish wiping at the time of wiping. Furthermore, since there is no adhesion of the spray foam to the injection port portion of the aerosol, the spray can always be sprayed in a good state.
