Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bathroom cleaning composition. For more details,
The present invention relates to a bathroom cleaning composition containing a cationic surfactant, a nonionic surfactant, and a water-soluble solvent.

[Conventional technology]

Bathrooms and bathtubs are often contaminated with organic and inorganic stains such as fatty acid metal salts (especially alkaline earth metal salts), calcium phosphate, fats and oils, and putrid proteins. detergent is used. Traditionally, bathroom detergents include acidic detergents based on nonionic surfactants, anionic surfactants, organic acids, and solvents, neutral detergents based on a combination of nonionic surfactants and anionic surfactants, and non-ionic detergents based on organic acids and solvents. There are alkaline detergents based on ionic surfactants, anionic surfactants, and sequestering agents such as alkanolamines or polyphosphoric acids.

[Problem that the invention attempts to solve]

However, unlike other household stains, the stains in the bathroom are mainly made of metal soaps, especially calcium salts of fatty acids, and the aforementioned neutral detergents and alkaline detergents cannot dissociate the metal soaps, so they can be quickly removed. Unable to remove dirt satisfactorily. Acidic detergents are effective in removing these stains, but they have the drawback that they not only reattach the stains after washing, making rinsing difficult, but also damage materials with poor acid resistance, such as marble bathtubs and metals. Furthermore, such acidic detergents have the problem of making the hands of housewives rough when actually doing the washing.

[Means for solving problems]

As a result of our studies to solve the above-mentioned problems, the present inventors discovered the detergency effect of cationic surfactants, and further,

Just spray it on the surface to be cleaned, leave it for a while, and then rinse with water. In addition, when cleaning the inside of a bathtub, add a specific concentration of cationic surfactant and nonionic surfactant to the water left after bathing, leave it for a certain period of time, preferably one hour or more, and then drain it. You can rinse the bathtub surface with water if you have it. In this case, the composition of the present invention has a cationic surfactant concentration of 0.5 to 100 ppn+, preferably 10 to 60 ppn+.
It is better to set it as pm.

[For production]

The cleaning mechanism of the composition of the present invention can be considered as follows.

The cationic surfactant causes a substitution reaction with the metal ion of the fatty acid metal salt, decomposing the fatty acid metal salt, or forming a complex to improve the dispersibility of dirt. However, if only a cationic surfactant is used, the substitution reaction of the fatty acid metal salt with the metal ion is inhibited because free fatty acids remain. However, when a nonionic surfactant and a water-soluble organic solvent coexist, it is presumed that a satisfactory cleaning effect can be obtained because the dispersion effect can be further enhanced and the substitution reaction can be continuously promoted.

〔Effect of the invention〕

By using the bathroom cleaning composition of the present invention, soap scum adhering to bathroom floors, walls, bathtubs, etc. can be satisfactorily removed without damaging the materials. Also, you don't have to worry about your hands getting rough.

〔Example〕

The present invention will be explained below with reference to Examples, but the present invention is not limited to these Examples.

Example 1 Acidic detergent using surfactant (nonionic surfactant, anionic surfactant) and malic acid as the acidic substance, only surfactant (nonionic surfactant, anionic surfactant) A neutral detergent using a surfactant (nonionic surfactant, anionic surfactant), a water-soluble solvent, and an alkaline detergent using sodium ethylenediaminetetraacetate as a sequestering agent, and the product of the present invention (A)
Table 1 shows the results of investigating the detergency and material damage properties of (B). The numbers in the table represent weight %.

The cleaning power was evaluated by gently scrubbing a cast iron enamel bathtub (zircon type) with bath stains that cannot be removed by scrubbing, using a sponge soaked in detergent, and determining which stains were easily removed by ○. Those in which almost no stain removal was observed were marked with an x mark and judged with the naked eye.

In addition, for material damage, the gloss condition of the surface of the cast iron enamel bathtub was similarly judged with the naked eye after the cleaning power test, and those where no change was observed were marked with an ○, and those where gloss had been lost and surface erosion was observed were marked with an X. And so.

As can be seen from the results in Table 1, acidic detergents using acidic substances have good cleaning power, but they are extremely damaging to materials, and the bathtub surface was damaged during the normal cleaning process. On the other hand, neutral detergents and alkaline detergents did not show any damage to the material, but their cleaning power was extremely poor and dirt could hardly be removed. Compared to these existing detergents, the product of the present invention had excellent cleaning power and was free from material damage.

Example 2 Using acidic detergents, neutral detergents, alkaline detergents, and products (C) and (D) of the present invention having the compositions shown in Table 2, the detergency was investigated. The results are also shown in Table 2. The numbers in the table represent weight %.
