Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an aerosol-type cleaning composition in which the sprayed foam is stable and easy to wipe off, and is effective against organic stains, especially persistent stains caused by deterioration of oils and fats. This article relates to an aerosol type cleaning composition that exhibits poor cleaning power.

[Conventional technology]

Aerosol type cleaning agents have been used for various purposes, such as for window glass and as an oil-soluble cleaner in kitchens.

Particularly in the kitchen, the oil used for cooking and its steam can evaporate into the surrounding area, not only around the range, but also on the walls, windows, and other areas inside the kitchen.
These oils adhere to ventilation fans, etc., and over time,
Under the influence of heat, light, and oxygen in the air, it degenerates into a brown sticky resinous substance and forms persistent oil stains. It was made easier to remove by swelling and emulsification. The above-mentioned aerosol type cleaning agent has so far been prepared by combining a surfactant with an alkaline agent such as a caustic alkali such as I-IJ hydroxide or potassium hydroxide, or an alkali phosphate, and then using a surfactant as a solvent.
A blend of monoalkyl ether such as monobutyl ether of ethylene glycol or diethylene glycol is used.

[Problem that the invention seeks to solve]

However, these cleaning agents have a drawback in that when the aerosol is sprayed, the unpleasant odor of the solvent in the cleaning agent composition is strongly felt, giving a user a feeling of discomfort. Further, there are disadvantages in that foam sprayed onto vertical surfaces such as walls tends to drip, and thermal properties such as foam stability and ease of wiping the foam are not necessarily sufficient.

Means for Solving Problem C] The present invention uses limonene and/or pinene, which are obtained from natural plants and are used in various fragrances, as a solvent.
This is based on the knowledge that when used together with a specific foam stabilizer, the synergistic effect of the two produces an air-sol type cleaning agent that is free from unpleasant odors and has excellent foam properties.

That is, the present invention provides (A) a non-soap surfactant (B
) IJ monene and/or pinene and (C) at least one foam stabilizer selected from polysiloxane with a degree of polymerization in the range of 30 to 450 and a fatty acid soap having 8 to 20 carbon atoms. The present invention provides a characteristic aerosol type cleaning composition.

As component (A) of the present invention, a surfactant is used.

Component (A) in the present invention is not particularly limited as long as it can emulsify and disperse or solubilize component (B) and promote soil wetting and emulsification and dispersion action, including non-soap anionic, Both nonionic and amphoteric surfactants can be used.

Specifically, the anionic surfactants include straight chain or branched alkyl (08-C22) benzenesulfonate, long-chain alkyl (Ca-2□) sulfonate, long-chain monoalkyl (C, -2□) Sulfate ester salt, polyoxyethylene (1 to 6 mol) long chain alkyl (ce to 22) ether sulfate salt, polyoxyethylene (1 to 6 mol) alkyl (C, to 18) phenyl ether sulfate salt, long chain Monoalkyl, dialkyl or sesquialkyl (C, ~
22) Phosphate, polyoxyethylene (1-6 mol) monoalkyl, dialkyl or sesquialkyl (08-2
□) Examples include phosphates.

The counter ions of these surfactants are sodium,
Alkali metal ions such as potassium, alkaline earth metal ions such as magnesium, or monoethanolamine,
Any alkanolamine ion such as jetanolamine or triethanolamine may be used.

In addition, as nonionic surfactants, polyoxyethylene (1 to 20 moles) long chain alkyl (C, ~2□) ether, polyoxyethylene (1 to 20 moles) alkyl (08
~, 8) Phenyl ether, polyoxyethylene polyoxypropylene block polymer, higher fatty acid (C, o
~20) Sucrose ester, higher fatty acid (C,, ~20
) Alka/-alamide or its alkylene oxide adduct, long chain tertiary amine oxide (C, 2-14)
Examples of amphoteric surfactants include amino acid type amphoteric surfactants, betaine type amphoteric surfactants such as alkyl acetate betaines and alkyl acetate betaines, and imidacilline type amphoteric surfactants. These surfactants are
Each can be used alone, but two or more types can be used in combination. The amount of component (A) to be blended may be arbitrary, but it is usually 0.5 to 10% by weight (hereinafter abbreviated as %) of the cleaning composition, preferably 1 to 8%. component(
Among the above-mentioned surfactants, A) is polyoxyethylene alkyl ether sulfate and polyoxyethylene alkyl ether sulfate, which are polyoxyethylene-added surfactants, from the viewpoint of emulsifying and dispersing effect and solubilizing effect on denatured dirt. Preference is given to olether, holoxyethylene alkylphenyl ether, and the amphoteric surfactant 2-alkylcarboxyethyl-N-hydroxyethylimidazolinium betaine.

Component (B) of the present invention is limonene, pinene or a mixture thereof. Limonene has d! Includes monolithic and racemic forms (dipentene).

As the pinene, a mixture of α-pinene and β-pinene, which is selected from α-pinene, β-pinene, and various turpentine oils, is used. These are usually obtained from valuable essential oils,
A synthetic product may also be used. From the point of view of manpower, d-limonene,
A mixture of α-pinene and β-pinene is preferred. Ingredients (B
) is used as a solvent to dissolve various organic stains, and accounts for 1 to 10%, preferably 2 to 8%, in cleaning compositions.
It is better to set it as %.

Component (C) of the present invention is a polysiloxane having a degree of polymerization within the range of 30 to 450 and/or a fatty acid soap having 8 to 20 carbon atoms. The polysiloxane may be linear, branched, ring-containing, etc. as long as the degree of polymerization is within the above range, but from the viewpoint of foam stability after air sole injection, the following formula (1) may be used. Dimethylpolyloxane represented by 'J) is preferred.

H3: ((In the formula, n represents an integer of 40 to 430.) Among these, those in which n is 100 to 350 are particularly preferred.

Further, as fatty acid soaps, alkali metal salts of saturated or unsaturated fatty acids having 8 to 20 carbon atoms, preferably 12 to 18 carbon atoms,
Alkanolamine salts, ammonium salts are used.

These foam stabilizers can be used alone as polysiloxane, alone as fatty acid soap, or in combination of both. The amount of component (C) in the cleaning composition is usually 0.005 to
2%, preferably 0.01-1%.

In the present invention, excellent effects are expressed by the combination of component (B) and component (C), particularly component (A)/(B) -'/, ~38, component (A )/
(C) -'/, it is more effective to set it to 1008.

The cleaning agent of the present invention contains a propellant for making it into an aerosol. As such a propellant, ordinary propellants such as LPG, dimethyl ether, carbon dioxide gas, and Freon can be used, but from the viewpoint of foaming stability, it is preferable to use LPG, dimethyl ether, and a mixture thereof. The content of the propellant in the cleaning composition is 1 to 20%, preferably 3 to 10%.

The remainder of the cleaning composition of the present invention is water, but various additives can be included depending on the purpose. In particular, it is preferable to incorporate an alkaline agent in order to improve the effect of removing dirt such as oil. Among these, 0.5 to 20%, preferably 1 to 10%, of monoethanolamine, jetanolamine, and triethanolamine, which are less rough on hands and have a greater effect in removing deteriorated dirt, are added to the cleaning composition. It is desirable to do so. Furthermore, it is also possible to incorporate solvents other than limonene and pinene within a range that does not reduce their effects. In addition, commonly used ingredients in detergents, such as various disinfectants, chelating agents, preservatives, fungicides, pigments, fragrances, etc., can be added.
