Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to aerosol-based cleaning compositions and articles for use in cleaning hard or soft surfaces.

Cleans hard surfaces such as glass surfaces such as window glass, mirrors, and fluorescent lights, porcelain surfaces such as tiles, chrome-plated surfaces such as steel lockers, and plastic surfaces such as decorative boards, as well as soft surfaces such as synthetic leather. In such cases, aerosol type cleaning agents are generally used. this is.

This is largely due to the ease of cleaning a dirty surface by simply spraying the cleaning agent directly onto the surface and wiping it off. □However, conventional aerosol-type water-based cleaners produce stable foam when sprayed and are too difficult to wipe off.

The problem is that dirt emulsified by the cleaning agent cannot be completely wiped off by wiping once or twice, leaving so-called wiping stains.

In particular, users are dissatisfied with the stains left on window glass and mirror surfaces.

The present inventors investigated the causes of stains left behind by conventional cleaning agents and found that certain components in cleaning agents are the main cause of stains left behind. That is, in the case of Japanese Patent Publication No. 44-9467, alkali metal polyphosphate causes stains, and in the case of Japanese Patent Publication No. 47-20033, dihexyl sulfosuccinate causes stains. In the publication, dimethylpolysiloxane, which has a relatively high molecular weight, is disclosed in JP-A-54-462.
In Publication No. 07, otsukanolamine was disclosed in Japanese Patent Application Laid-open No. 55-7.
No. 840 discloses that high molecular weight silicic anhydride is the source of wipe stains.
It was confirmed that Therefore, the present inventors have conducted extensive studies on an azole-type aqueous cleaning agent composition that does not contain any of these stain-causing components, yet has a satisfactory level of cleaning power and has appropriate foam stability. , the present invention was accomplished.

That is, the aerosol type aqueous detergent composition of the present invention,
It is characterized by containing the following components (A) to (D).

(A) Nonionic surfactant and/or anionic surfactant 0.01-0.3wt% (
B) Lower alcohol 3 to 15 wL% (C) Morpholine 0.1 to 1 wt% (o) C, -C,, at least one type of hydrocarbon -cs to cts alcohol and its ester 0.001 to 0.3 tyt% ( Δ)
The component nonionic surfactant and/or anionic surfactant is used alone or as a mixture, and is present in the composition at 0.01 to 0.3% by volume, preferably 0.0%.
It is contained in an amount of 2 to 0.2 wt%. If the cleaning power is below this range, the detergency will decrease, and if it is above this range, there is a risk that stains may remain after wiping once or twice.

Specific examples of nonionic surfactants include (1) c.
~C16 alkylphenol EO adduct (EO average added mole number 6-12), C2) Cm~C2o aliphatic alcohol EO adduct (EO
(3) C, to C, j secondary alcohol EO adduct (average number of added moles of EO 6 to 15), and the like. Here, EO represents ethylene oxide (the same applies below).

Specific examples of anionic surfactants include (1) c, ~
C16 aliphatic alcohol EO addition sulfate salt (E
O average number of moles added 1 to 5), (2) C1, to C20α
-olefin sulfonate, (3) C-a~Cte alkylbenzene sulfonate, (4) C@~C71l
Examples include sulfate ester salts of aliphatic alcohols.

Component (B), lower alcohol, is a component that dissolves oily contaminants and facilitates their removal, and methanol, ethanol, or isopropyl alcohol is suitable for this purpose. The blending amount of lower alnogol is preferably in the range of 3 to 15% to 17% in terms of detergency, ease of wiping, odor, and liquid properties. If the amount of lower alcohol is less than 3%, the cleaning power will deteriorate.
At the same time, there is a risk that solid matter will precipitate in the cleaning agent, which will cause the spray nozzle to become clogged. Also, 1
When the content exceeds 5%, not only can no special effects be expected, but the flash point is actually lowered, which poses a safety problem.

The amount of morboline (C) component is 0.1 to 1 wt% from the viewpoint of cleaning power, ease of wiping, and odor.
selected within the range.

(D) Component C5-C18 hydrocarbon, C5-C18
Examples of alcohols and esters thereof include the following. That is, examples of C5 to C18 hydrocarbons include terpene hydrocarbons such as limonene, pinene, caryophyllene, cedrene, and myrcene, and preferably C8 to C25.

These hydrocarbons may be used alone or in combination. 05-C18 alcohols and their esters include phenyl ether alcohol, benzyl alcohol,
-primary alcohols such as alcohol, geraniol, citronellol, xantalol, secondary alcohols such as men-1--ol, borneol, carveol, ethyl-II-hexylcarbinol, vetiverol, linalool, Terpineol, myrcenol, cedrol,
Tertiary alcohols such as dihydromycenol and tetrahydrolinalool, and their acetate esters, linalyl acetate, benzyl acetate, geranyl acetate, isobornyl acetate, citronellyl acetate, myrcenyl acetate, and teryl acetate. Examples include hydrolinallylacetate-1-. These alcohols can be used alone or in combination, and can also be used in combination with the above-mentioned hydrocarbons. Above (D
) Among the components, limonene, linalool, dihydromircenol, and linalyl acetate are preferred. (D) component is 1
It contributes to stabilizing the foamed state, and since too large a content may cause staining, in the present invention, the amount of 0.00
Selected in the range of 1 to 0.3 wt%, preferably 0.0
05-0.2%.

Although any conventional propellant can be used as the propellant component of the present invention, it is preferable to use propane, butane, dimethyl ether, or a mixture thereof in view of the foam stabilizing effect of the hydrocarbons and alcohols mentioned above. .

The aerosol type detergent composition of the present invention is prepared by blending each of the above-mentioned components in water in the above-mentioned quantitative range in a conventional manner. In this case, optional components such as glycol ether, bactericidal agents, fragrances, chelating agents, and rust preventives can be added as appropriate.

As is clear from the detailed description above, the aerosol type cleaning composition of the present invention substantially eliminates polyphosphate or dihexylsulfosuccinic acid, alkanolamine, high molecular weight silicic anhydride, and dimethylpolysiloxane, which cause stains. Even if it does not contain 05 to C18 hydrocarbons, C, -C, alcohol or its ester, the foaming of the detergent after injection and maintaining its state in a moderately stable manner makes the detergent ready. To fully demonstrate the cleaning effect. EXAMPLES The effects of the present invention will be specifically explained below with reference to Examples.
