Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a foaming cleaning composition for drain pipes, and more particularly, it has excellent foaming properties and sustained foam stability, and is firmly attached to drain pipes. The present invention relates to a cleaning composition that can effectively remove dirt attached to surfaces.

BACKGROUND OF THE INVENTION Conventionally, it has been known to use peroxides such as sodium percarbonate as cleaning agents for drain pipes. The mechanism of cleaning drain pipes using peroxide is to apply physical vibration or peeling force to the dirt firmly attached to the inner surface of the drain pipe due to its foaming action, and to remove it from the drain pipe. It is something to do.

Known foaming cleaning compositions for drain pipes generally have low foaming properties (foaming power) and lack the sustainability of foam, and foam does not form in drain pipes, especially curved parts such as U-shaped pipes. There was a problem with the delivery.

Outline and Purpose of the Invention The present inventor uses an anionic surfactant and a nonionic surfactant in a specific combination as described below as a surfactant.
It has been found that when combined with soda percarbonate, the foaming properties and foam sustainability are significantly improved.That is, the object of the present invention is to provide a foaming product for drain pipes that has significantly improved foaming properties and foam sustainability. To provide a cleaning composition.

Another object of the present invention is to provide a foaming detergent composition that is excellent in cleaning and removing dirt that is firmly attached to drain pipes, particularly those having a curved pipe portion such as a U-shaped pipe.

Structure of the Invention According to the present invention, 50 to 90% by weight of sodium percarbonate, 0 to 30% by weight of an alkali agent, 1 to 50% by weight of an anionic surfactant, 1 to 511 t% of polyoxyethylene alkylphenol ether, and fatty acid ethanol. There is provided a foaming cleaning composition for drain pipes which is characterized by containing 0.1 to 1.0 weight tS of amide and has excellent foaming properties and foam persistence.

Features and Effects of the Invention The present invention provides a combination of the above-mentioned anionic surfactant, polyoxine ethylene alkylphenol ether as a nonionic surfactant, and fatty acid ethanolamide,
This is based on new findings that the foaming power and foam persistence of soda percarbonate can be significantly increased.

FIG. 1 of the accompanying drawings is a plot of the relationship between elapsed time and foam height for the foaming cleaning composition of the present invention and a commercially available foaming cleaning composition. According to the results shown in FIG. 1, it can be seen that the cleaning agent of the present invention is not only significantly superior in the height of the foam formed and the foaming property, but also in the sustainability of the foam. . In particular, it was a completely surprising fact that the height of the foam reached its maximum value 6 hours after filling, and that the state of the foam was maintained even after 5 hours of filling.

Conventionally, it has been known that surfactants have cleaning effects by wetting and moistening dirt, emulsifying dirt, and dispersing dirt, but the cleaning agent of the present invention has foaming properties and foam sustainability. As a result, the foam reaches every corner of the drain pipe, and the contact between the foam and dirt continues for a long time, so dirt can be effectively removed and cleaned from any part of the drain pipe. It is.

Preferred embodiments of the invention The present invention will be described in detail below with respect to its preferred embodiments.

The cleaning composition of the present invention contains 50 to 90% of sodium percarbonate.
One of the characteristics is that it is contained in a large amount such as 30 to 80% by weight, especially 30 to 80% by weight. That is, if the amount of sodium percarbonate used is less than the above range, the desired foam height cannot be obtained when cleaning a drain pipe.

As the anionic surfactant CA), any anionic surfactant known per se can be used, but sulfate ester salts and sulfonate salts can be mentioned as particularly suitable for the purpose of the present invention. These anionic surfactants exhibit particularly excellent foaming properties and foam sustainability in combination with nonionic surfactants described below.

Among the nonionic surfactants used in the present invention, polyoxyethylene alkylphenol ether (B) is mainly useful for enhancing foaming properties, while fatty acid amide CC) is mainly useful for foam sustainability. be.

By using these activators in combination at a ratio of A:B2021-30:1-5: 0.1-1% by weight, not only the dirt cleaning power but also the foaming property and foam sustainability can be improved. The optimal combination can be obtained.

The cleaning composition of the present invention may contain up to 30% by weight of an alkaline agent for the purpose of promoting stain removal and assisting f9 foaming. Such alkaline agents include
Examples include soda carbonate, sodium sesquicarbonate, and sodium metasilicate.

Furthermore, pigments, fragrances, etc. can be added to this composition if desired.

This cleaning composition is used in the form of powder for cleaning drain pipes. That is, 20% of the cleaning composition was applied to the drain pipe to be cleaned.
Pour in about 50f, then pour 100 to 300cc of water into the drain pipe, leave it in this state for 1 to 5 hours,
Finally, flushing the water ensures that the drain pipe is thoroughly cleaned.

EXAMPLE The invention is illustrated by the following example. Prepare the following prescription ingredients.

Soda percarbonate 74 Soda ash 20 Higher alcohol sulfur ester soda 3.0, t' IJ oxyethylene nonylphenol ether 2.4 Fatty acid diethanolamide 0.6 First, add the nonionic surfactant component to soda ash and stir thoroughly. After that, add soda percarbonate and stir thoroughly.
Finally, add the 7-ionic surfactant and stir thoroughly to obtain a bulk specific gravity of 0.71 to 0.81 f/Wt and an effective oxygen amount of 9.
．． A drain pipe cleaning agent in the form of powder or granules containing 6% or more was prepared.

Into a measuring cylinder, put the cleaning agent of the above example and commercially available drain pipe cleaning agents A, B, and C according to the standard usage amount, and then pour 30tZ' of tap water (50cc) all at once through a funnel, and leave for 30 minutes. The height of the foam was measured after 1 hour, 6 hours and 5 hours.The results are shown in FIG.

Next, the artificial dirt shown in Table 1 below was applied to the glass U-shaped pipe in an amount of 10 (1/i) to create a model of a dirty drain pipe. Ingredients Calcium stearate 20 Calcium thioleate 20 Rapeseed oil
40 Kanto Rohm JIS Dust 11th class
20 Pour each of the above-mentioned cleaning agents into this discharge pipe according to their standard usage amounts, then pour about 50 cc of water, and
Allowed time to pass. Thereafter, water was poured into the U-shaped tube, it was dried, and the remaining stain on the glass tube was visually evaluated.

With the commercially available cleaning agent, dirt remained on the upper part of the U-shaped tube, whereas with the cleaning agent of the example, no dirt remained on any part of the U-shaped tube.
