Description

DETAILED DESCRIPTION OF THE INVENTION This invention consists of a composition containing 85-99% sodium citrate, 1-15% sodium percarbonate, and 0.01-1% sodium percarbonate decomposition aid, The present invention also relates to a cleaning agent for drain pipes, etc., in which sodium percarbonate and a sodium percarbonate decomposition aid are each coated with a surfactant.

In recent years, with the westernization of housing and the appearance of high-rise buildings in urban areas, various food waste, excreta, bathroom grime, hair,
Fibrous materials such as paper gradually adhere to and accumulate in the drains, eventually clogging them, and causing frequent malfunctions such as blocking drainage and producing bad odors.

In order to solve this problem, various drain pipe cleaning agents have been developed and are commonly used, but none of them are satisfactory in terms of cleaning effectiveness, handling safety, or corrosiveness to drain pipes. Therefore, it has been desired to develop a cleaning agent that is further improved in these respects.

The inventor of this invention has developed a cleaning agent for drain pipes, etc. that is improved in terms of safety, has no problem with corrosivity to drain pipes, and has an excellent cleaning effect. 85-99% sodium citrate with dissolving action and sterilization,
By adding 1 to 15% of sodium percarbonate, which has a deodorizing effect, all kinds of inconveniences associated with drainage pipes can be eliminated.
．． The cleaning, sterilizing, and deodorizing effects are promoted when 01 to 1% of sodium percarbonate coexist, and more reliable effects can be expected.Furthermore, if the decomposition aid and sodium percarbonate are coated in advance with a surfactant, etc. This invention was completed by discovering that it can be stored stably for a long period of time.

The cleaning agent for drain pipes, etc. of this invention contains 85% sodium citrate.
~99%, 1-15% sodium percarbonate and 0.01-1% sodium percarbonate decomposition agent, and each of the sodium percarbonate and sodium percarbonate decomposition aid is coated with a surfactant. The composition consists of

Examples of the sodium citrate in this invention include sodium metacitrate, sodium ortho citrate, etc. When preparing the composition of the present invention, if these sodium citrates are used and dried with ventilation at a low temperature in advance, the composition can be changed. This is desirable because it improves the stability of objects.

Examples of the decomposition aid for sodium percarbonate include various metal salts, metal oxides, sugars, oxalic acid, reducing agents, etc. Among them, sulfuric acid steel is the most preferred.

The blending ratio of this decomposition aid is appropriately determined in the range of 0.01 to 1% depending on the blending ratio of sodium percarbonate. It is desirable that the sodium percarbonate and sodium percarbonate decomposition aid of the present invention be pre-coated with a surfactant to prevent inconveniences associated with blending each component and to improve the stability of the composition.

Coping of sodium percarbonate and its decomposition agent is carried out in a conventional manner using a surfactant as a coating agent.

As surfactants, nonionic surfactants such as polyoxyethylene higher alcohol ether, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene fatty acid ester, or sodium olefin sulfonate,
Examples include anionic surfactants such as sodium alkylbenzenesulfonate and sodium alkylsulfonate. The cleaning agent for drain pipes, etc. according to this invention further includes fragrances,
Additives commonly added to compositions of this type, such as colorants, excipients, etc., may also be added.

When using the cleaning agent for drain pipes, etc. of the present invention, a more excellent cleaning effect can be obtained by first spraying an appropriate amount of the agent around the upper entrance of the drain pipe, and then gradually pouring hot water thereon.

In other words, the cleaning agent is dissolved in the drain pipe by the boiling water, and the sodium citrate acts to dissolve various organic substances and other dirt that has adhered to and accumulated on the trap and the inner wall of the pipe. The nascent oxygen generated from the accelerated decomposition of sodium percarbonate acts to achieve sterilizing and deodorizing effects in a short time.

In addition, the oxygen rapidly generated by the reaction between sodium percarbonate and its decomposition aid creates a kind of momentum effect on solutions containing cleaning agents and dirt as it rises in the pipe, causing the dissolution of organic matter by sodium citrate. Promote action. moreover,
The surfactant used as a coating agent also has the effect of retaining oxygen-containing bubbles generated from sodium percarbonate within the pipe and prolonging the action of the cleaning agent. As a result of the comprehensive effects of each component as described above, the cleaning agent of the present invention has superior cleaning, disinfection, and swamp odor effects compared to conventional similar products.

Next, the cleaning agent for drain pipes, etc. of the present invention and its preparation method will be explained with reference to Examples.

Example 1 Sodium metacitrate 89.8% Sodium percarbonate 8.0% Polyoxyethylene oleyl ether 0.5% Sodium Q-olefin sulfonate 042% Sulfuric acid bowl
0.14% Magnesium metacitrate aluminate 1.06% Fragrance
0.3% Sodium percarbonate is first coated with polyoxyethylene oleyl ether, and sulfuric acid steel is coated with a mixture of polyoxyethylene oleyl ether and sodium Q-olefin sulfonate, respectively, in a conventional manner.
