Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detersive composition containing an active halogen generating agent such as a chlorine bleach or a fungicide, and in particular, it can suppress the generation of halogen gas harmful to the human body. Detergent composition.

[0002]

2. Description of the Related Art For example, hypochlorites such as sodium hypochlorite make good use of their excellent bleaching power, and are used for clothing bleaching agents, kitchen bleaching agents, fungicides, toilet cleaners, drainage pipes. It is used as a bleaching agent such as a cleaning agent and a disinfectant cleaning agent, and as a germicidal cleaning agent. However, since this hypochlorite salt produces toxic chlorine gas by the action of acid, it is extremely dangerous when used in combination with an acidic detergent. Therefore,
At present, it is obligatory that the bleaching detergent containing sodium hypochlorite, etc. and the acidic detergent containing hydrochloric acid, etc., each be labeled as "Dangerous to mix".

[0003]

However, the above-mentioned display of "mixed danger" is merely to draw the user's attention, and it cannot be said that it is sufficiently safe.

Further, most of so-called chlorine agents for skid used in pools and kitchens of general households use trichloroisocyanuric acid, and no indication of "mixed danger" is given.

Therefore, it is an object of the present invention to suppress generation of halogen gas, which is harmful to the human body, in a halogen-based detersive composition such as a chlorine-based bleaching agent, a fungicide, and a chlorine agent for sliding off. The goal is to provide a product that can and is safe.

[0006]

The detersive composition of the present invention which solves the above-mentioned problems is a water-soluble solid compound (A) which generates active halogen, and a halogen metal which reacts with the water-soluble solid compound. The halogen scavenger (B) forming a salt is contained in a weight ratio of A / B = 1/59 to 1/5.

In one aspect of the present invention, the halogen scavenger is at least one selected from the group consisting of calcium hydroxide, magnesium hydroxide, sodium bicarbonate, sodium hydroxide and barium hydroxide.

In one embodiment of the present invention, the water-soluble solid compound is selected from the group consisting of chlorinated isocyanuric acid and its salts, calcium hypochlorite and 1-bromo-3-chloro-5,5-dimethylhydantoin. It is at least one kind.

In one embodiment of the present invention, 2/3 of the main component composed of the water-soluble solid compound and the halogen scavenger is used.
It also contains a binder in a weight ratio of ˜1 / 1.

In one aspect of the present invention, the binder is at least one selected from the group consisting of polyethylene glycol and polyoxyethylene polyoxypropylene glycol ether.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described according to preferred embodiments.

The detersive composition of the present invention comprises a chlorinated isocyanuric acid and its salts, calcium hypochlorite and 1-bromo-3-chloro-, as a generator of active halogen.
It contains a water-soluble solid compound consisting of at least one of 5,5-dimethylhydantoin. Of these,
Particularly preferred is sodium dichloroisocyanurate or calcium hypochlorite, which has a high solubility in water.

The cleansing composition of the present invention has at least one of calcium hydroxide, magnesium hydroxide, sodium bicarbonate, sodium hydroxide and barium hydroxide as a halogen scavenger for suppressing the generation of halogen gas. Contains seeds. Of these, calcium hydroxide is particularly suitable.

Further, the detersive composition of the present invention can be used, for example,
In the case of processing into tablets or granules, at least one selected from the group consisting of polyethylene glycol and polyoxyethylene / polyoxypropylene / glycol ether is used as the main ingredient consisting of the above-mentioned active halogen generator and halogen scavenger. It is preferred to mix the seeds as a binder. At this time, since polyoxyethylene / polyoxypropylene / glycol ether is less soluble in water than polyethylene glycol, the dissolution rate of the detersive composition of the present invention can be appropriately adjusted by adjusting the compounding ratio of both. It is possible to adjust.

Next, the detersive composition of the present invention can be used, for example,
The case of applying it to a skid agent used in a kitchen of a general household will be described.

First, sodium dichloroisocyanurate is used as an active halogen generator, calcium hydroxide (slaked lime) is used as a halogen scavenger, and polyethylene glycol (molecular weight 6000) is used as a binder. These are mixed at a weight ratio of sodium dichloroisocyanurate / calcium hydroxide = 1/59 to 10/50, and a weight ratio of main agent composed of sodium dichloroisocyanurate and calcium hydroxide / binder = 1/1 to 3/2. The obtained product is processed into tablets of 20 to 30 g by dry tableting.

The tablet or a tablet obtained by crushing the tablet into granules is wrapped in a non-woven bag, and for example, it is hung or placed in the dust receiver of the drainage port of the sink for use. Then, every time water is poured into the drain port, the tablets or granules are gradually melted to prevent the drain port from slipping and a bad odor. Moreover, even when vinegar, fruit juice, or an acidic or chlorine-based cleaning agent (bleaching agent, fungicide, etc.) is flown, the action of calcium hydroxide suppresses the generation of chlorine gas harmful to the human body. Also,
Placing these tablets or granules in a garbage container such as a plastic container can prevent an offensive odor.

At this time, the smaller the ratio of calcium hydroxide to sodium dichloroisocyanurate, the less the effect of suppressing chlorine gas, but within the range defined by the present invention, for example, sodium dichloroisocyanurate / water Calcium oxide = 1/5 weight ratio shows sufficient safety at domestic wastewater level. On the other hand, if the proportion of calcium hydroxide is increased beyond the range specified in the present invention, the effect of preventing slippage and offensive odor is diminished, which is not preferable.

Further, the smaller the ratio of the binder to the main agent, the larger the amount of the drug dissolved at one time.
However, if it is too small, tablets and granules will be lost in a short number of days, which is not preferable. As a standard,
When using 225 liters of water a day in the kitchen, it is good to have about 20 to 30 days. On the other hand, if the ratio of the binder to the main agent is increased beyond the range specified in the present invention, it becomes difficult for the drug to dissolve, and the effect of preventing slippage and malodor is diminished, which is not preferable.

The detersive composition of the present invention is, for example, a bleaching agent for tableware, a bleaching agent for toilets, a bleaching agent for bathrooms, in addition to the above-mentioned slippery agents used in the kitchen of general households. It can be applied to mildew remover, etc. In that case, the shape and size of the tablet or the particle size of the granule is appropriately changed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to specific embodiments.

Example 1 With respect to the cleansing composition of the present invention, a chlorine gas generation test was carried out based on the general industrial product quality display regulations.

The measuring method is in accordance with the same regulations. (A) An acidic type standard solution 3 is applied to the bottom of the synthetic resin container using a pipette.
Place a 10 ml beaker containing ml. (B) Add 3 ml (or 3 g) of the chlorine-based product stock solution into the beaker of (a). (C) Immediately cover the container, mix with a magnetic stirrer, and stir the inside of the tank with a fan. (D)
Five minutes after mixing both liquids, a gas sampler was connected after the detection tube and 100 ml of gas in the container was sucked once for measurement, and the chlorine gas concentration was calculated from the obtained numerical value by the following formula. Chlorine gas concentration (ppm) = (measured chlorine gas concentration (pp
m) / 3) × (volume of synthetic resin container (l) / 20) (e) Room temperature, liquid temperature is 20 ± 5 ° C.

According to the same regulations, the standard solution was hydrochloric acid 9.3 to 9.7%, the measurements of (a) to (d) were carried out three times, and the average value was taken as the measured value. The results are shown in [Table 1].

[0025]

[Table 1]

In this Table 1, in the examples of the present invention, sodium dichloroisocyanurate / calcium hydroxide (weight ratio) was A = 6/54, B = 5/55,
Mixed powders with C = 4/56, D = 2/58 and E = 1/59 were used respectively. In addition, as a comparative example, samples A to
The results of performing the same chlorine gas generation test using only the respective amounts of sodium dichloroisocyanurate of E are shown. That is, in the comparative example, A = 3 g × 6/60,
B = 3 g × 5/60, C = 3 g × 4/60, D = 3 g ×
The above chlorine gas generation test was conducted using a sample of 2/60, E = 3 g × 1/60 sodium dichloroisocyanurate alone.

As can be seen from these results, when sodium dichloroisocyanurate is mixed with calcium hydroxide according to the present invention, generation of chlorine gas is significantly suppressed.

Example 2 Sodium dichloroisocyanurate: calcium hydroxide: polyoxyethylene / polyoxypropylene glycol ether: polyethylene glycol (molecular weight 60
00) = 1: 59: 30: 10, and the mixture was processed into 3 g tablets. And as sample F,
Example 1 was used in which tablets were crushed into powder, sample G was used as a sample G, and sample H was used as sample H in which a tablet was placed in a non-woven bag and the surface was wet with distilled water.
A chlorine gas generation test similar to the above was performed. The results are shown in [Table 2].

[0029]

[Table 2]

As can be seen from these results, when the detersive composition of the present invention is made into tablets, the chlorine gas scavenging effect is somewhat reduced, but, for example, the occurrence of 1 ppm, which is obligatory to display "mixed danger", is generated. Less than quantity. Also,
Even if the tablets are kept in a non-woven bag, the generation of chlorine gas is hardly seen because calcium hydroxide reacts with chlorine gas in the wet bag.

[0031]

Industrial Applicability The detersive composition of the present invention can remove or prevent slippage and offensive odor by the bleaching and sterilizing effect of active halogen, and at the same time suppress the generation of halogen gas harmful to the human body. It is highly likely.
