Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a composition for preventing stains caused by silicic acid scale, excrement, etc. adhering to the ceramic surface of a flush toilet bowl.

The black or brown stains found on the water interface and the area where the flush water flows into the flush toilet bowl with a ceramic surface are extremely stubborn stains, such as ToI, strong acid, strong alkali, etc.
It is difficult to remove even with strong chemicals such as bleach, and this is not limited to water bottles and toilet bowls, but also tap water (supply water) containing trace components. This is a phenomenon that commonly occurs in situations where this used water is exposed to the glass surface of ceramic objects such as water reservoirs or water receivers, repeated loading, and drying. Big.

The present inventors have carefully studied this stain and found that the main 5YIA is silicic acid contained in used water such as tap water, and that it can strongly adhere to the ceramic surface as silicic acid scale. Find out what it is.

There is feces and urine in the flush toilet bowl.)
Dirt caused by excrement also adheres to the surface of the water.

One of the main objectives of the present invention is to provide a composition that has the effect of preventing stains caused by silicic acid scale, excrement, and the like.

That is, the flush toilet cleaner composition of the present invention comprises (a) a cationic agent, OI) a polyoxyethylene alkyl ether-type surfactant, and (
・)A (characterized by containing a door type amphoteric surfactant).

Among the cationic surfactants as component (a), quaternary ammonium salt type cationic surfactants having 1 to 3 alkyl groups having 12 to 22 carbon atoms are preferred, and in particular, the following general formula ( I) ~■.

(In the formula, R1 is an alkyl group with a storage prime number of 12 to s, and -
X represents a halogen such as chlorine or bromine, methyl sulfate or ethyl sulfate. ) (In the formula, Rs and Rs are an alkyl group having 12 to 20 carbon atoms.) (In the formula, -0- and - are an alkyl group having 12 to 1 carbon atoms.) (In the formula, Rt is an alkyl group having 12 to 22 carbon atoms.

Among these, especially Preferably, - is an alkyl group having 6 to 14 carbon atoms, and 9 is an alkyl group in which the alkyl group has 6 to 12 carbon atoms, and the alkyl group has 6 to 12 carbon atoms.

A specific example of this surfactant is (ll N-(N'-hydroxyethyl-W-caloxymethylacetyl) lauryl ido natriu 4 +2) N-(N,V-dical Ixhetylainoethyl)-N-hydroxy 7ethyl lauryl iodine tometrium salt (31N-(M-hydroxyethyl-W-calukishetylainoethyl) ) Laurylamide Metriu 4 etc., and these can be used alone or in combination of 8 or more types.

The composition of the present invention has the above (a)% (b) and (@)F
! It contains as an essential component, but if desired, it may also contain coloring agents such as Round Blue No. 1 to impart freshness, deodorization, aromatic fragrances, as well as chelating agents, bactericidal agents, stabilizers,
Bulking agents and the like can be added.

The antifouling mechanism by the superimposed bright line fltliII7 can be considered as follows.

When a cationic surfactant is added to water, it adsorbs to the ceramic or glass surface, making the ceramic (glass) surface hydrophobic, rounding it, and increasing the contact angle between the water surface and the ceramic (glass) surface. This prevents moisture from evaporating and preventing dirt from adhering to the interface, that is, the ceramic surface.

To produce this effect, add a cationic surfactant to the water! It is appropriate to contain I to 20 ppm, preferably 0.1 to 21 prm. If this amount is less than OOI ppm, the adsorption area of the cationic surfactant will be small and the effect will not be sufficient.
If 111V is absorbed, polymolecules will be adsorbed, and the ceramic surface will become hydrophilic again, making it impossible to obtain a sufficient effect.

However, if a cationic surfactant is used alone, as it is repeatedly used, the cationic surfactant will accumulate and the ceramic surface will become hydrophilic again, reducing its effectiveness in preventing the adhesion of silicic acid scale. When a nonionic surfactant is present, this reduction can be suppressed and the silicic acid scale adhesion prevention effect can be maintained. In addition,)
The details of the contribution mechanism of 1-on surfactant are unknown. The concentration of nonionic surfactant in the water used is 14 @ Oppm

II! , it is appropriate to add substances.

If it is less than IPg)01, a sufficient effect of adding the nonionic surfactant cannot be obtained, and if it exceeds IOpvm, the nonionic surfactant itself will be concentrated and adhered at the interface, which is not preferable.

By using cationic and nonionic surfactants in combination with this 15, it is possible to prevent scale adhesion on flush toilet bowls or flush water tanks, but it is also effective in preventing stains caused by excrement, especially organic matter adhesion. It has little effect on (・) Amidami/lid surfactant effectively prevents the adhesion of such organic substances, and (a) and -

If it is less than ppax, a sufficient effect cannot be obtained;

As mentioned above, the composition of the present invention is used by being administered into the washing water in a uniform manner, so its properties can be in various forms such as liquid or supported on other carriers. Also, the concentration and content of each component in the composition can be selected as appropriate.
