Technical Field

The present invention relates to a liquid detergent composition for hard surfaces, a method for cleaning hard surfaces, and a detergent article for hard surfaces packaged in a spray container.

Background

For a dish cleaner for hand washing, a cleaning force against greasy dirt is strongly demanded. In particular, in tableware having a hydrophobic surface such as a plastic sealed container or a lunch box, oil stains containing a large amount of solid fat such as beef tallow or lard are less likely to fall off, and a high cleaning force is required. Therefore, a cleaning method using hot water at about 40 to 45 ℃ or performing 2 times of cleaning is generally used.

JP-A2013-100462 discloses a liquid detergent composition for hand dishwashing, which comprises (a) an alkyl sulfosuccinate or a salt thereof, (b) an anionic surfactant having a hydrocarbon group having 8 to 21 carbon atoms and a sulfate group or sulfonate group [ wherein, except for (a) ]5 to 35 mass%, and (c) a sulfobetaine type surfactant, and which shows a rich foamability at the time of dishwashing and a foam persistence at the time of cleaning, and which is free from foam instantaneously at the time of rinsing and is completed with a small amount of water.

JP-A2013-100461 and JP-A2013-100462 disclose that a liquid detergent composition for hand dishwashing is adhered to a flexible material such as a sponge to foam, and the dishware is scrubbed.

Detailed Description

Liquid detergent composition for hard surface

The liquid detergent composition for hard surfaces of the present invention can enhance the interaction between the component (a) having 2 hydrocarbon groups having a relatively high hydrophobicity and a relatively high hydrophilicity and the component (c) as an amphoteric surfactant by specifying the content of the anionic surfactant having a hydrocarbon group having 8 to 21 carbon atoms and a sulfate group or a sulfonate group in the component (b). It is presumed that the surfactant contained in the liquid detergent composition for hard surfaces of the present invention is likely to penetrate into oil stains containing solid grease, and the solid grease is likely to be peeled off from the hard surface, and as a result, an effect of improving the cleaning force is obtained.

Further, in the case of using the liquid detergent composition for hard surfaces of the present invention in a method of directly contacting a hard surface, the concentration of the surfactant applied to the hard surface becomes higher than in the case of contacting the hard surface with an aqueous sponge. Thus, the effect produced by the surfactant of the present invention is more remarkably exhibited.

In view of these circumstances, by using the liquid detergent composition for hard surfaces of the present invention, excellent cleaning force can be obtained even when oil stains containing solid grease adhering to hard surfaces of plastics or the like are rubbed with a flexible material such as a sponge or the like, that is, a cleaning method in which mechanical force is not applied.

(1) Cleaning power (solution impregnation evaluation)

Preparation of beef tallow and canola oil 9: the mixture obtained by mixing the materials at a mass ratio of 1 was used as a sample stain (a sample stain containing greasy dirt of solid fat, the same applies hereinafter). The mass of a polypropylene test piece of 30mm (horizontal) ×80mm (vertical) ×1mm (thickness) was measured (x) using a one-ten-thousandth balance. A test piece was produced by uniformly coating a sample stain on both surfaces of the polypropylene test piece from the lower end to a height of 50mm so that the total of the both surfaces became 0.02 to 0.03 g. The mass of the stain sheet was measured (y) using a ten-thousandth balance.

50G of the liquid detergent composition for hard surfaces was added to a 50mL container (cylindrical shape having an inner diameter of 35 mm. Times. A height of 68 mm), and then 1 stain sheet was allowed to stand in the container to come into contact with the above composition. At this time, the entire portion of the stain sheet to which the stain is attached is immersed in the composition in the container.

The stain sheet was left for a period of time shown in table 1 in a state of being immersed in the liquid detergent composition for hard surfaces in the container, and thereafter, the stain sheet was taken out and rinsed with running water for 1 minute. At this time, the conditions of the running water flushing are: the tap water had a temperature of 25℃and a flow rate of about 4L/min, and the tap had an opening with a diameter of about 15mm. The stain sheet was held at 45 ° to tap water falling down to the stain sheet located vertically below 5cm from the opening, and the tap water flowing over the stain sheet was used to flush the entire surface of the cleaning portion while the tap water was received at the upper end portion of the stain sheet to which no stain was attached, with the angle fixed. At this time, the front and back surfaces were alternately rinsed every 10 seconds. After the rinse was completed, the stain sheet was dried and the mass was measured using a ten-thousandth balance (z). The cleaning rate was determined by the following equation.

Cleaning rate (%) = { (y) - (z) }/{ (y) - (x) } ×100

(2) Cleaning power (foam impregnation evaluation)

Preparation of beef tallow and canola oil 9:1 as a sample stain. The mass of a polypropylene test piece of 30mm (horizontal) ×80mm (vertical) ×1mm (thickness) was measured (x) using a one-ten-thousandth balance. A test piece was produced by uniformly coating a sample stain on both surfaces of the polypropylene test piece from the lower end to a height of 5cm so that the total of the both surfaces became 0.02 to 0.03 g. The mass of the stain sheet was measured (y) using a ten-thousandth balance.

The hard surface was filled with the liquid detergent composition in a trigger spray container (MAGICLEAN HANDY SPRAY manufactured by Kagaku corporation) and the composition was sprayed in a foam form 5 times in a 50mL container (cylindrical shape having an inner diameter of 35 mm. Times. A height of 68 mm). The amount of the composition discharged was about 5g.

Then, 1 stain sheet was set up in the container, and the stain sheet was brought into contact with the foam-like liquid detergent composition for hard surfaces in the container. At this time, the entire portion of the stain sheet to which the stain is attached is immersed in the foam-like composition in the container. The stain sheet was left in a state immersed in the foam for a period of time shown in table 1, and thereafter, the stain sheet was taken out and rinsed with running water for 1 minute.

At this time, the conditions of the running water flushing are: the tap water had a temperature of 25℃and a flow rate of about 4L/min, and the tap had an opening with a diameter of about 15mm. The stain sheet was held at 45 ° to tap water falling down to the stain sheet located vertically below 5cm from the opening, and the tap water flowing over the stain sheet was used to flush the entire surface of the cleaning portion while the tap water was received at the upper end portion of the stain sheet to which no stain was attached, with the angle fixed. At this time, the front and back surfaces were alternately rinsed every 10 seconds. After the rinse was completed, the stain sheet was dried and the mass was measured using a ten-thousandth balance (z). The cleaning rate was determined by the following equation.

Cleaning rate (%) = { (y) - (z) }/{ (y) - (x) } ×100

(3) Specific volume of foam

The hard surface was filled with the liquid detergent composition in a trigger spray container (MAGICLEAN HANDY SPRAY, manufactured by Kagaku corporation) and sprayed 10 times into a 200mL measuring cylinder (inner diameter 40 mm) using the rich foam mode of the container. The mass of a 200mL measuring cylinder after spraying was measured using a one-ten-thousandth balance, and the difference between the mass of the measuring cylinder before spraying and the mass of the measuring cylinder before spraying was set as a foam application amount (g) (a). The volume of foam (mL) in the cylinder was read visually (b). The specific volume of the foam was calculated using the following formula.

Specific volume of foam (mL/g) = (b)/(a)

When example 5 of table 1 was compared with examples 14 to 17 and comparative examples 4 to 5 of table 2, it was confirmed that: (b) Example 5, in which the mass ratio of/(a) + (b) + (c) ] is 0, is excellent in terms of cleaning power. On the other hand, it can be confirmed that: (b) The foams of examples 14 to 17 having a relatively large mass/[ (a) + (b) + (c) ] have a relatively large specific volume.

In the case of contacting the hard surface of the present invention with the liquid detergent composition, if example 5 of table 1 is compared with examples 18 and 19 of table 2, it can be confirmed that: example 5, in which the total content of the component (a), (b) and (c) was 5% by mass, was more excellent in terms of the balance between the detergency and the raw material cost of the surfactant.

When examples 2 to 8 in table 1 were compared in the case of bringing the hard surface of the present invention into contact with the liquid detergent composition, it was confirmed that: (a) Example 6, in which the mass ratio of component/(c) was 1.5, was more excellent in terms of cleaning force.

When the liquid detergent composition for hard surfaces of the present invention was brought into contact with the hard surface, it was confirmed that the liquid detergent composition of example 6 and examples 9 to 13 in table 1 were compared with each other: (e) Example 10, which had a mass ratio of component/[ (a) + (c) ] of 1.8, was more excellent in terms of cleaning power.

Further, if examples 5, 6, 16, and 17 were observed, the relationship of the cleaning rates under solution impregnation of these examples exhibited the same tendency as the relationship of the cleaning rates under foam impregnation of these examples. From this, it was found that the cleaning rate under the solution impregnation and the cleaning rate under the foam impregnation were correlated, and in other examples, it was confirmed that the value of the cleaning rate under the foam impregnation could be estimated from the result of the solution impregnation (cleaning rate).
