Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition for a drain pipe,

The present invention relates to a drain pipe cleaning composition and a cleaning method using the same. More specifically, the present invention relates to a drain cleaning composition for foam cleaning, which can maximize a cleaning effect on a drain pipe.

The drainage pipe and the drain pipe of the sink are food which remains in the process of cooking or throwing out food, and it is always wet in water and the microorganism is easy to grow, which makes it easily messy and causes a bad smell. However, it is inconvenient, time-consuming and labor-intensive to clean the sewer or drain line to keep it clean, which is problematic because there is no special alternative to the method of replacing the drain line or the drain line.

To solve this problem, U.S. Patent Application No. 2014-529388 discloses a two-component system in which hydrogen peroxide is foamed with a hydrolytic enzyme such as amylase to clean the piping. However, such a system is disadvantageous in that the bactericidal bleaching power of hydrogen peroxide is significantly lower than that of sodium hypochlorite, so that the bactericidal bleaching effect is not sufficiently exhibited.

In addition, U.S. Patent Application Publication No. 2003-0171234 discloses a method in which a sodium hypochlorite composition having a viscosity and a foaming agent are poured at the same time and foamed to clean the pipe. However, in such a cleaning method, sodium hypochlorite and the foaming agent are difficult to uniformly mix, and there is a limit to maintain the cleaning power because the foam is not discharged for a long time to the vertically installed pipe of the sink.

Therefore, it is very important to control the compounding ratio of the components so that the sodium hypochlorite is mixed with the foaming agent in the sieve, drain and drain pipe when the drain pipe cleaner composition is used to sufficiently induce the foaming reaction, thereby remarkably improving the sterilization and cleaning effect. Do.

Accordingly, a problem to be solved by the present invention is to provide a cleaning agent composition capable of maximizing a cleaning effect on a drain pipe by cleaning a drainage port and a drainage port with bubbles generated by using a drain pipe cleaning agent for foam cleaning and gradually flowing the cleaning agent into a drainage pipe .

In order to solve the above problems, the present invention provides a foam system capable of slowly flowing a detergent for cleaning a duct cleaning pipe for a foam cleaning to a drain pipe, and a composition capable of effectively cleaning a filtering network and a drain pipe of a kitchen sink using the foam system. Specifically, the present invention provides a drain pipe cleaner composition, preferably a drain cleaning cleanser composition for foam cleaning, comprising a detergent comprising hypochlorite, a detergent comprising hydrogen peroxide which is a foaming agent.

As a result of intensive researches to overcome the problems of the prior art, the inventors of the present invention have found that when a hypochlorite and hydrogen peroxide are mixed in a specific ratio in a cleaning composition for a pipe cleaning for foam cleaning, a disinfecting and cleaning effect And the present invention has been completed.

In the present invention, the cleaning composition for a foam cleaning washer can be used without any particular limitation as long as it is a cleaning composition commonly used, such as a composition containing a lactose for cleaning a sieve, a drain or a drain pipe.

In the present invention, the detergent composition for cleaning a foamed washer may be composed of a one component containing hypochlorite and a two component component containing two hydrogen peroxide. The detergent composition of the present invention can be used in combination with one or two separate liquids before use and can produce a large amount of foam in the squeezing net, drain and drain pipe of the sink during mixing, .

In the present invention, the reaction between hypochlorite and hydrogen peroxide is a reaction in which oxygen is generated to cause foaming as shown in the following reaction formula (1). In addition, the foaming reaction can be generated by various methods. For example, there is a reaction between an organic acid (citric acid or lactic acid, etc.) or an inorganic acid (e.g., sulfamic acid) with sodium carbonate or sodium hydrogencarbonate and a surfactant or a bactericide, Can be obtained. However, in the present invention, hypochlorite and hydrogen peroxide are reacted as a main component to generate a foaming cleaning effect. In this case, the effect is more excellent than other foaming cleaning methods.
