Abstract

PROBLEM TO BE SOLVED: To obtain a floor cleaning composition exhibiting excellent cleaning and antifoaming capabilities and suitable for floor cleaning by using an automatic floor cleaner or a wet vacuum cleaner. SOLUTION: This floor cleaning composition is characterized in that it contains (a) 0.01-20 wt.% of an anionic surface active agent, (b) 0.01-15 wt.% of cationic surface active agent, (c) 0.1-30 wt.% of nonionic surface active agent, and (d) 0.5-30 wt.% of a glycol ether based solvent. The composition may further contain 1-20 wt.% of an organic builder. The composition, since the scum to occur in the reaction between the ingredients (a) and (b) inhibits foaming, exhibits an excellent antifoaming capability despite it contains no silicone based antifoaming agent.

In recent years, however, the demand for floor cleaners having more detergency has been insufficient in the performance of the above-mentioned conventional floor cleaners. In addition, when used as an automatic washing machine or a cleaning agent for wet vacuum, there is a problem that when collecting waste water after washing, foaming is remarkable and overflows before collection, and the washing machine stops. In order to suppress the foaming, there is a method of adding a silicone-based antifoaming agent to a wastewater tank, but there is a problem in workability and cost. As a recent automatic washing machine, there is a washing machine that puts a cleaning agent into both tanks of sewage and fresh water, sends water from the sewage tank to the fresh water tank, and circulates the used washing machine. When a system antifoaming agent is used, there is a disadvantage that the silicone liquid makes it easy to slip. further,
When compounding a silicone-based antifoaming agent into a cleaning agent, there is also a problem that the stability of the cleaning agent is poor and it cannot be uniformly mixed. As described above, a floor cleaning agent having both excellent detergency and defoaming property suitable for performing floor cleaning with an automatic floor washer or wet vacuum has not yet been obtained.

The floor cleaning composition of the present invention eliminates the disadvantages of the above-mentioned prior art floor cleaning compositions, and is also suitable for performing floor cleaning with an automatic floor cleaning machine or wet vacuum. An object of the present invention is to provide a floor cleaning composition having excellent detergency and defoaming properties.

[Table 1]

The following performance tests were conducted to clarify the performance of the obtained floor surface cleaning composition. The results are shown in Table 1.

(1) Detergency A white homogeneous floor tile was used as a test floor material, and after applying a polish (trade name "Poly's Yusilon Coat Coloring Pica") to this, a previously prepared stain was applied. The test floor was then cleaned using a washability tester. The cleaning rate was obtained and evaluated by measuring the lightness of the floor material surface before and after the test. For cleaning, test liquids prepared by diluting the floor cleaning compositions of Examples and Comparative Examples 100-fold with water, respectively, were used. (Test conditions) Number of washing times and washing direction: 50 reciprocal washings Cleaning equipment: White pad Soil: 20 parts by weight of carbon black, JIS Z890
An artificial soil consisting of 30 parts by weight of the test dust and 50 parts by weight of mineral oil was applied, left at 70 ° C. for 20 hours, and excess artificial soil was wiped off. Washing rate (%) = [(G3-G2) / (G1-G2)] ×
100 G1: Lightness before dirt application G2: Lightness after dirt application G3: Lightness after cleaning

(2) Antifoaming property 200 ml of a test solution prepared by diluting each of the floor cleaning compositions of Examples and Comparative Examples 100 times with water was placed in a beaker, and a red pad (diameter 9 cm) was provided at the tip. After stirring at 1100 rpm for 15 seconds with a stirrer equipped with
The defoaming property was evaluated by measuring the volume of the sample liquid (total volume of the liquid portion and the foam). The evaluation results are shown in the following four stages. ◎: 200 to 300 ml in volume ○: 300 to 500 ml in volume △: 500 to 700 ml in volume ×: 700 ml or more

(3) Stability After the detergent compositions of Examples and Comparative Examples were allowed to stand at room temperature for 1 hour, the state was visually evaluated. The evaluation result is
：: stable, ×: separated in two stages.

As can be seen from Table 1, all of the test liquids prepared from the cleaning compositions of the examples exhibited high detergency of 85% or more in detergency, and showed a volume increase of 2% after the defoaming test. The defoaming property was good at not more than 0.5 times (500 ml), and the composition was also excellent in liquid stability. On the other hand, the compositions of Comparative Examples 1 to 3 containing an anionic surfactant but not containing a cationic surfactant could not obtain the defoaming effect. Further, Comparative Example 4 containing an anionic surfactant and a cationic surfactant but not containing a nonionic surfactant had low detergency, and Comparative Example 5 containing no glycol ether-based solvent showed liquid stability of the composition. Was missing.
