Description

The present invention relates to a detergent composition used in the form of an aerosol for cleaning oil stains such as around a kitchen range, in which the sprayed foam adheres to the spray object and the foam It is related with the foaming detergent composition which improved the washing | cleaning efficiency of the spray target object by defoaming.

There are various types of cleaning agents around the kitchen range, such as shower type, trigger spray type, and aerosol spray type. The type that foams and attaches the cleaning liquid has the effect of making it easier to understand the part that has been treated with the cleaning agent, but has the disadvantage of being difficult to wipe off if left in the form of foam. It is desirable to do. Furthermore, in Patent Document 1 and Patent Document 2 (Japanese Patent Publication No. 6-72239 and Japanese Patent Publication No. 7-30360), the attached foam is further defoamed to further increase the cleaning power. It is also known to get.

By the way, as a proposal of a preparation in which a liquid agent is foamed with an aerosol and defoamed after spraying, for example, in Patent Document 3 (Japanese Patent Laid-Open No. 2012-46725), polyoxyethylene alkyl ether as a foaming agent and carbon as a water-soluble solvent are disclosed. Foam which consists of undiluted solution and liquefied gas containing monohydric alcohol of 2 or 3, polyol, water, and oil and liquefied gas. In addition, Patent Document 4 (Patent No. 3558393) discloses a stock solution containing a lower alcohol, water, an oil component, and a specific nonionic surfactant, and a vapor pressure of 25 ° C. A foamable aerosol composition is disclosed which comprises a propellant of ² to 7 kg / cm ² · G, foams when injected, and defoams itself without being broken. However, the undiluted solution of both inventions is blended with a lower alcohol that lowers the flash point and is not suitable for use around a range with a flame.

[Test Example 1]
According to Example 1, the foaming detergent composition of the composition shown in Table 1 was prepared, and the following detergency test, foam performance test, and flash point measurement of the cleaning liquid were performed. Moreover, the composition shown in Table 2 as a comparative example was prepared and evaluated similarly.
(1) Detergency test A commercially available salad oil and a cobalt dryer were mixed at a mass ratio of 95: 5 and stirred at room temperature for 90 minutes, and 0.1 g was applied to a 5 × 10 cm stainless steel plate. After heating at 120 ° C. for 60 minutes, various effervescent detergent compositions were sprayed on those cooled at room temperature. After standing for 3 minutes, a load of 150 g was applied with a detergency tester, and the mixture was rubbed once with a urethane sponge soaked in water. After rinsing with running water, it was dried, and the washing rate was determined by the formula (1) from the weight before and after washing, and evaluated according to the following evaluation criteria.
○: Cleaning rate of 80% or more △: Cleaning rate of 50-80%
X: Cleaning rate less than 50%

Cleaning rate (%) = (A−B) / (A−C) × 100 (1)

A: Weight of stainless steel plate before cleaning
B: Weight of the stainless steel plate after cleaning
C: Weight of stainless steel plate (2) Foam performance Commercial salad oil and cobalt dryer mixed at a mass ratio of 95: 5 and stirred at room temperature for 1 day 10 cm in the long side direction of a 30 x 40 cm PVC plate The width was applied. After heating at 60 ° C. for 1 hour, the product cooled to room temperature was set up vertically, and the foaming property and antifoaming property / adhesion when spraying various foaming detergent compositions were observed and evaluated according to the following criteria.
<Foaming properties>
○: Good foaming Δ: Foaming is not enough ×: Almost no foaming <Defoaming and adhesion>
○: Defoaming after spraying to adhere to dirt.
Δ: Foaming disappears after spraying, but it is insufficient and many bubbles remain.
X: No defoaming (3) Flash point of the cleaning liquid The flash point of the cleaning liquid was measured by the method of JIS K2665-1: 2007, and the evaluation was made according to the following evaluation criteria.
○: Flash point is 40 ° C or higher ×: Flash point is lower than 40 ° C

(Note) * 1 Coconut alkyl dimethylamine oxide * 2 Sodium α-olefin sulfonate * 3 Sodium linear alkylbenzene sulfonate * 4 IP Clean LX Idemitsu * 5 Exol D40 Exxon Mobil * 6 Dipropylene glycol n-butyl ether * 7 Ethylene glycol phenyl ether

As a result of the test, all of the foaming detergent compositions (Examples 2 to 10) of this example showed good detergency against oil stains, good foaming properties when sprayed, and against vertical surface stains. It was confirmed that it adhered by defoaming and effectively removed dirt. Further, the wiping operation was simplified, the cleaning operation around the range was extremely efficient, and the flash point of the cleaning liquid was 40 ° C. or higher.
On the other hand, in Comparative Example 7 in which the surfactant (A) was not blended, the detergency was reduced and the foam did not foam. (B) Comparative Examples 1 to 4 in which no component oil is blended, or (C) Component R ₁ — (O—R ₂ ) _m —OH (I) represented by formula I
(Here, R ₁ represents a C ₃ -C ₆ alkyl group or an optionally substituted phenyl group, R ₂ represents a C ₂ -C ₃ alkylene group, and m is an integer of 1 to _3. ) )
In Comparative Example 6 in which No is added, defoaming does not occur after foaming, so that the wiping operation took time as compared with the present Example. Comparative Examples 8 and 9 using ethanol instead of the component (C) corresponded to dangerous materials having a flash point of less than 40 ° C. Further, Comparative Example 8 containing 10% by mass of ethanol did not defoam, and Comparative Example 9 containing 20% by mass of ethanol had a tendency to defoam, but did not defoam depending on the state of the target surface. . In Comparative Examples 5 and 9 in which the alkali agent of component (D) was not blended, the detergency was insufficient.

The effervescent detergent composition of the present invention may be used for cleaning not only oily dirt such as around a range and a ventilation fan but also other oily dirt.
