JPH0788169A - Water treating agent composition for toilet - Google Patents

Abstract

PURPOSE:To obtain an excellent deodorizing power and to improve detergency and sterilizing power by preparing the treating agent to be used for toilets of rolling stock, aircraft, etc., by incorporating a chlorhexidine gluconate and quaternary ammonium salt surfactant therein. CONSTITUTION:This water treating agent for toilets contains the chlorhexidine gluconate (GCH) and the quaternary ammonium salt surfactant therein (cation). The microorganisms, such as intestinal bacterial flora, included in the night soil are as extremely many as >=10<7> pieces/ml and, therefore, the excretas successively deposited in a filth tank of the toilet are decomposed by the microorganisms and malodorous materials, such as ammonia and hydrogen sulfide, are generated. The cation sterilizes the microorganisms, such as intestinal bacterial flora, and decreases the microorganisms and cleans the filth, coloring agents, tissue paper, etc., sticking to the ball and pipings of the toilet. The remaining microorganisms failed to be sterilized by the cation alone are so acted by the GCH as not to propagate any more. The generation of the malodors is thus prevented.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a water treatment composition for toilets. Circulating toilets and suction toilets are used in railway vehicles, aircraft, ships, and long-distance buses. When using the circulating type toilet, put an appropriate amount of water in the filth tank, add and dissolve the water treatment agent for the toilet in this, and press the switch after each use to circulate the wash water by the circulation pump to wash the toilet bowl. It is a method to do. Therefore, since the excrement is mixed in with the wash water after the second use, the treating agent for circulating toilet water is required to have washing power, coloring power, deodorizing power, sterilizing power and the like. The suction type toilet is a system in which the centralized waste tank is depressurized and the waste is collected from each toilet by suction. The water used to flush the waste is new (not reused) each time it is used.
Must be less than 200 ml / 1 time. Therefore, it is desirable that the running water has sufficient cleaning power and sterilization power so that dirt does not adhere to the balls and remain.

[0002]

2. Description of the Related Art Conventional water treatment agents for toilets have used nonionic surfactants and anionic surfactants as cleaning agents. Further, as a colorant, a blue direct dye, an acid dye, a basic dye, a pigment, etc., and as a bactericide, a salt of chlorinated phenol, chlorinated isocyanuric acid, a compound having effective chlorine such as chloramine T, formalin, and a cation. As deodorants such as activators, fragrances and the like have been used to mask offensive odor components such as ammonia and hydrogen sulfide generated from human waste. However, in the masking method using a fragrance,
During use, it becomes a mixed odor of sewage and fragrance, which is unpleasant for some people. Further, when effective chlorine is used as a bactericide, a pungent odor peculiar to chlorine is struck by the nose, which mixes with a fragrance odor to give an unpleasant odor to some people, and it cannot be said to be a satisfactory toilet treatment agent.

[0003]

In order to remedy this drawback in recent years, 2-bromo-2-nitropropane-1,3-diol (in order to deodorize sulfur compounds such as hydrogen sulfide and ammonia generated from human waste, and ammonia. In the following, the use of BNPD) has been proposed (JP-A-2-154764). B
NPD is effective in preventing spoilage and decomposition of human waste, but when used alone, it has poor bactericidal activity and is short-lived, and most of it is capable of cleaning dirt, colorants, dust paper, etc. adhering to toilet bowls and pipes. It has the drawback of not having it. The present inventors have conducted various studies to develop a water treatment agent for toilets which is excellent in deodorizing ability, and sufficiently satisfies detergency and sterilization ability. As a result, chlorhexidine gluconate (hereinafter abbreviated as GCH) and No. 4
It has been found that the use of a quaternary ammonium salt surfactant (hereinafter abbreviated as cation) as a water treatment agent for toilet is extremely effective.

[0004]

[Function] Since the amount of microorganisms such as intestinal sterilization contained in human waste is as high as 10 ⁷ or more / ml, the excrement accumulated in the waste tank of the toilet is decomposed by the microorganisms and is a bad smell of ammonia and hydrogen sulfide. To occur. The cation sterilizes microorganisms such as intestinal bacteria and reduces the number of microorganisms, and also cleans dirt, coloring agents, dust paper, etc. adhering to toilet bowls and pipes. Furthermore, by using GCH together, the remaining microorganisms that could not be killed by the cation alone act synergistically to prevent the generation of bad odors so that they do not grow any further. Until now, attempts have been made in this way. It never happened.

[0005]

The present invention includes a GCH and a fourth
A water treatment composition for toilets containing a surface-active ammonium salt surfactant.

GCH used in the present invention is known as a bactericidal and deodorant agent for medicine and industry, and a commercially available product can be used. Examples of the cation used in the present invention include, but are not limited to, the following compounds. Octadecyl trimethyl ammonium chloride, alkyl (beef tallow) trimethyl ammonium chloride, dodecyl trimethyl ammonium chloride, alkyl (palm)
