Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides dyes, fragrances, and cleaning agents that can be used by being immersed in the flush water tank of a flush toilet.

Continuously releasing disinfectants and other cleaning agents for flushing toilets.

When using a flush toilet, there is a need to use a flush toilet air freshener that releases ticy II colorants and fragrances into the flush water to increase the sense of cleanliness after use, and to remove dirt during flushing.
Various types of cleaning agents for flushing toilets have been used in the past, the purpose of which is to release cleaning agents into the flushing water. These flush toilet cleaners are placed in the flush water tank (water tank) of the flush toilet and emit a fragrance in the running water.

It imparts coloring, cleaning effects, etc., and comes in liquid types, solid types filled in containers, and drop-in replacement types.

In the liquid type, a liquid containing dyes, pigments, detergents, etc. is placed in a container, and the shape of the container is devised so that a certain amount of the liquid is released.

The fixed container filling type mixes and melts a water-soluble polymeric substance as a carrier with disinfectants, deodorants, fragrances, etc.
It is used by being packed in a plastic container with flK holes. As a carrier, slowly soluble polyethylene glycol,
d! ! Polymeric substances such as lipropylene glycol and PluCl nickel nonionic activators are known, but all of the cleaning agents using these carriers swell when immersed in water for a long time, resulting in a muddy surface. There is a problem that cleaning ingredients such as disinfectants can be dissolved into the water without limit and can be leached into the water without limit.The drop-in type is a type in which the solid cleaning agent is placed directly into the aquarium without using a container. It is. Although it is economical and easy to use since it does not require a container, it has the problem that it is difficult to adjust the dissolution rate. As a carrier, a combination of a mono- or di-flucaramite fatty acid, which is a dissolvable surfactant, and a surfactant that is relatively easily soluble in water is known, but when these carriers are used, There is a problem that alkanolamide fatty acids float to the water surface as insoluble matter.

In addition, it swells greatly in water, and depending on the flow of flushing water, it can cause a large amount of water to swell in the toilet bowl. ! There is also the drawback that the cleaning agent may flow out.

The present invention has focused on a carrier for the cleaning component of a solid type cleaning agent, in particular, a carrier that has appropriate solubility, can be used in the above-mentioned drop-in replacement type, and does not cause floating of insoluble matter. As a result, it is complete.

Generally, the tank for washing water has a capacity of 10 to 15 J, and the time during which 12 J of water for one use is supplied is one degree of decentralization. For example, if you put 50g of solid detergent in this and use it, it will last for 5 months (assuming you use the toilet about 500 times).
In order to maintain the effect over K, the diameter of K is 29φ■.

Solid detergent with a thickness of 7V (5.4±0.2F) 1
It was found that the amount of dissolved water when added to 1 water and stirred for 5 minutes at 60 ± 2 Ppm must be 50η or less.If the amount of dissolved water is too small, the cleaning effect will not be sufficient. Therefore, it is generally preferable to exhibit a dissolution amount of about 15 inches or more in the above test.

The present inventors conducted experiments with various compounds, and found that the main carrier was a compound in which the terminal hydroxyl group of an ethylene glycol module or propylene glycol polymer or a copolymer thereof was protected with a specific substituent. It has been found that by using it as a component, it is possible to obtain a shed cleaner for flushing toilets that has appropriate solubility characteristics and does not contain floating insoluble matter.

That is, the solid detergent for flush toilets of the present invention has the general formula (f) R,O(-CH,CHO+nR.

The solid salt detergent of the present invention uses the compound of general formula (1) as a carrier, and contains effective portions of any detergents such as fragrances, dyes, surfactants, and bactericides, and 7, builders, feeders, etc. can do. If it contains fragrance, the vkK aroma will waft and give a refreshing feeling.

If it contains a pigment, the washing water will be colored and give a refreshing feeling, and if it contains a surfactant, a cleaning effect can be expected, and if they are used together, the sum of the effects will be obtained. It will be done. The solid detergent of the present invention may also contain ethylene glycol, a Solminic type nonionic surfactant, etc. as a carrier.

For example,

It! of the present invention! The detergent may further contain builders or feeders. The builder is general K/? They act as detergents, but some, such as alkali metal carbonates in alkali metal polysonoates, impart water-softening properties to solid detergents. The builder can be added in an amount of about 55% by weight, preferably up to 20% by weight, and a specific example thereof is an alkali metal polyphosphate.

Examples include cinnabar, boric acid monobicarbonate, cyclides and sulfates, carbonyl oxymethyl cellulose (s) vinyl alcohol, clay, diatomaceous earth, etc. Also, as a water softener, for example, ethylenodia Tetraacetic acid may also have its alkali metal base added thereto.

To actually prepare the solid detergent of the present invention, each component may be mixed and formed into an appropriate shape, for example, a tablet weighing 20 to 150 g, preferably 30 to 70 g. In addition, water-soluble substances that dissolve when immersed in water, such as polyvinyl alcohol, can be easily handled during transportation.
- It is also possible to wrap the solid phase detergent in a protective agent such as a plastic wrapper.

Since the solid detergent for flush toilets of the present invention contains a compound represented by the general formula (1) as a carrier,
