Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning composition, and more particularly to a cleaning composition suitable for bathroom use.

Dirt in the bathroom consists of organic and inorganic stains such as fatty acid metal salts (mainly polyvalent metal salts of calcium), free fatty acids, glycerides, and nitrogen-containing compounds. To remove these stains, acidic substances and interfaces are required. Acidic cleaning agents containing activators and solvents are effective. However, this product has a low pH of 3 to 6, which is problematic when it is desired to apply coloring, which has a large impact on the consumer's image of the product. In other words, the colorants that can be used are limited in terms of safety, ability to color the items to be washed, and stability, but most of them are resistant to light and heat in the presence of surfactants. It was easy to discolor or fade. Conventionally, therefore, countermeasures have been taken, such as adding ultraviolet absorbers to the resin material or liquid content of the container, or coloring the container.

The present inventors believe that the cause of discoloration and fading is in the detergent system.
As a result of extensive research into the compatibility between cleaning agent systems and various colorants, we found that by selecting a specific cleaning agent system and a specific colorant, even with a small amount of colorant added, light resistance and heat resistance can be achieved. The present inventors have discovered that a yellow-colored liquid cleaning composition with excellent properties can be obtained, and have completed the present invention.

That is, the liquid cleaning composition of the present invention has the following (A) to
(It is characterized by containing a Dl component.

(N nonionic surfactant 1 to 20% by weight, (BJ hydroxy polycarboxylic acid or its salt 1 to 10% by weight, (C1 average degree of polymerization of polypropylene glycol or propylene oxide of 5 to 25 weight %) ~25
Glycerin or trimethytff-propane propylene oxide adducts 1 to 20 types, (DJ Yellow No. 203 (Cr A 47005), C
One or more colorants selected from I Acid Yellow (CI-ya 56205) and CI Acid Yellow (CI Black 23900), o, ooooooi to 0.01 weight percent.

(The non-molded surfactant, which is the N component, is molded in the detergent composition in an amount of 1 to 20% by weight, preferably 3 to 15% by weight. If this amount is less than 1% by weight, the dirt component On the other hand, 20vt%
Exceeding this will cause discoloration, and the foam will not cut easily.
Reduces the efficiency of washing millet.

Specific examples of nonionic/ionic surfactants include polyoxyethylene higher alkyl ethers in which the average number of moles of ethylene oxide added is 6 to 2o and the number of carbon atoms in the alkyl group is 10 to 20; -20 and polyoxyethylene alkylphenyl ethers in which the alkyl group has 6 to 12 carbon atoms are mentioned, and among these, the former is preferred.

Furthermore, it is effective to add an anionic surfactant within a range that does not impede the effects of the present invention. By using a mixed surfactant system of a nonionic surfactant and an anionic surfactant, it is possible to further prevent color change and fading without reducing detergency. An excessive amount of anionic surfactant may actually cause discoloration and fading, so it is appropriate to add 10 wt% or less, and usually 1 to 10 wt%, preferably 3 to 7 wt%.

Specific examples of anionic surfactants include C10-18 higher alkyl sulfates, alkyl groups having 10 carbon atoms,
~18 alkylbenzene sulfonate, Cs-,6 α-olefin sulfonate, alcohol residue has 8 to 1B carbon atoms, and average added molar particle of ethylene oxide is 1 to 1
10 higher alcohol polyoxyethylene ether sulfate.

Component (B), hydroxy polycarboxylic acid or its salt, is present in the composition in an amount of 1 to 10 wt%, preferably 3 to 8 wt%.
It is. If this amount is less than I wt%, a sufficient cleaning effect will not be obtained, and even if it is added at 1 wt% or more, the stain removal ability will not improve. Specific examples of hydroxy polycarboxylic acids include general A compound represented by formula (1) is exemplified.

(wherein, X is Hl-CH3, -CH,OH or HOC
It represents HCOOH, and Y represents ■ or -OH. ) Among these, malic acid, citric acid, tartaric acid, or salts thereof are preferred, and malic acid, citric acid, or salts thereof are particularly preferred. Further, examples of the salts of hydroxy polycarboxylic acids include sodium salts, potassium salts, monoethanolamine salts, jetanolamine salts, and triethanolamine salts.

(Component Q is used as a solvent υ, (1) polypropylene glycol with an average degree of polymerization of 5 to 25, (11) an average number of added moles of propylene oxide of 5 to 25.
25 glycerol propylene oxide adduct or (lil) The average number of added moles of propylene oxide is 5
~2 s t7)) Lime f-roll propane propylene oxide adduct is used. When the average degree of polymerization or the average number of added moles is less than 5, sufficient detergency cannot be obtained, and when it exceeds 25, solubility deteriorates. Among these, polypropylene glycol is preferred, and those with an average degree of polymerization of 8 to 20 are particularly preferred.

Component (C) is contained in the composition in an amount of 1 to 20 wt%, preferably 3 to 15 wt%. If this amount is less than 1 wt%, a sufficient wet dissolution effect cannot be obtained; on the other hand, if this amount is less than 1 wt%,
Even if the content exceeds the above, the effect will not be improved.

This component (C') does not have a solvent odor like ethylene glycol moptyl ether or monoethyl ether, which have been conventionally used as solvents.

The coloring agent of component (D) is Yellow No. 203 (CI71147
005), CI Acid Yellow 7 (CIAcidYe
one or more selected from CI Acid Yellow 7) (CIA56205) and CI Acid Yellow 44, and 0.0% in the cleaning composition.
00001 to 0.01 wt% is blended. These coloring agents color the composition yellow in small amounts, and furthermore, the color does not change even under sunlight exposure or high temperature environmental conditions in the cleaning agent of the present invention.

The composition of the present invention also contains hydrotropes such as ethanol and ethylene glycol, bactericides, fungicides,
It may also contain chelating agents, rust preventives, abrasives, fragrances, and the like.

The liquid cleaning agent of the present invention is colored a desirable yellow color by a small amount of coloring agent, does not change color or fade even when used or stored in a transparent container under environmental conditions, and has extremely good heat resistance and light resistance. Moreover, it has excellent characteristics such as good detergency, foaming, and foam removal, less roughness on hands, and no solvent odor.

Examples Various liquid cleaning agents having the compositions shown in Table 1 were prepared, placed in transparent containers, and the color changes were examined after one month of exposure to sunlight and one month of storage at 45°C.The results are shown in Table 1. It was shown to.
