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, chryserite, and nitrogen-containing compounds. Acidic cleaning agents containing activators and solvents are effective. However, since this product has a low pH of around 1 to 2, it has the drawbacks of damaging the joints of tiles, damaging materials with poor acid resistance such as metals, and making hands rough.

To solve this problem, the pH of the cleaning agent should be adjusted to 4.5 to 7.
．． A composition adjusted to 5K has been proposed (Tokuko Kokō 5).
5-9036), this product uses ethylene glycol monobutyl ether, ethylene glycol monoethyl ether, etc. as a solvent, so it has a strong solvent odor.
It had the disadvantage of causing discomfort and choking when cleaning the bathroom.

The present inventors have solved the above-mentioned drawbacks, and the hand is less rough.
As a result of extensive research into a cleaning composition that has no solvent odor and exhibits excellent cleaning power, we have found that polypropylene glycol or propylene glycol adducts with a specific degree of polymerization and a specific hydrocarbon or alcohol are used as the solvent. The inventors have discovered that the intended purpose can be achieved by doing so, and have come up with the present invention.

That is, the present invention is characterized by containing the following components (4) to (0).

(4) 1 to 20% by weight of nonionic surfactant, 1 to 10% by weight of hydroxy polycarzenic acid or its salt, (average number of added moles of polypropylene glycol or propylene oxide with Q average degree of polymerization of 5 to 25) 1-20% by weight of 5-25 glycerin or trimethylolpropane propylene oxide adduct.

(g) Hydrocarbon having 5 to 18 carbon atoms and/or alcohol having 5 to 18 carbon atoms or ester thereof 0.01 to
5.0 weight 1*.

The present invention will be explained in detail below.

The component (4), a nonionic surfactant, is contained 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 1wt1, it will not be possible to wet the dirt components and promote the decomposition of dirt by hydroxy polycarboxylic acid, so a sufficient cleaning effect will not be obtained;
%, this effect will be saturated and will not be improved, and on the contrary, the foaming will become worse and the efficiency of the cleaning work will be reduced.

Specific examples of nonionic surfactants include those with an average number of added moles of 6 to 30 and 0.6 to . , a polyoxyethylene alkyl ether having a primary or secondary alkyl group, a polyoxyethylene alkylphenyl ether having an average added mole number of 6 to 30 and an alkyl group of C8 to 6, and the like.

Component (B), hydroxy polycarbic acid or its salt, is present in the composition in an amount of 1 to 8 wt, preferably 3 to 8 wt. If the amount is less than 1 wt%, a sufficient cleaning effect cannot be obtained, and even if the amount is more than 10 wt%, the dirt removal ability will not be improved. Specific examples of hydroxy polycardinic acid include compounds represented by general formula (I).

In formula C, X is H, -0H3, -0H20H or HOO
It represents HOOOH, and Y represents H or -OH. ) Among these, malic acid, citric acid and tartaric acid or salts thereof are preferred. Examples of the salts of hydroxy polycarbic acid include sodium salts, potassium salts, monoethanolamine salts, jetanolamine salts, and triethanolamine salts.

(Component Q is used as a solvent, and includes (1) polypropylene glycol with an average degree of polymerization of 5 to 25, (1) an average number of added moles of propylene oxide of 5 to 2
Glycerol propylene oxide adduct of 5 or (...) The average number of moles of propylene oxide added is 5 to 2
A trimethylolpronozone propylene oxide adduct of No. 5 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.

(The Q component is 1 to 20 wt% in the composition, preferably 3 to 20 wt%.
Contains 15wt. If the content is less than 1 wt%, the wetting and dissolving effects as a solvent will not be sufficiently exhibited, and if the content exceeds 20 wt%, the effects will not improve.

As the component (b), at least one of (D O! 1-88 hydrocarbons and (1) 0-18 alcohols or esters thereof is used. Specific examples of C1-18 hydrocarbons include limonene, pinene, caryophyllene. Examples include terpene hydrocarbons such as , cedrene, and myrcene, and preferably C3 to 1. Examples of 0. to 8 alcohols or esters thereof include phenylethyl alcohol, benzyl alcohol, cheraniol, citronellol, and santalolnato. Primary alcohols, menthol, zerneol, cal-4-ol, ethylhexylcarbinol, secondary alcohols such as pethylol, linalool,
Examples include tertiary alcohols such as terpineol, mil-heptinol, cedrol, and tetrahydrolinalool, and esters thereof, such as linalyl acetate, fornylacetate, and geranyl acetate. Among these CI) components, limonene, pinene, phenylethyl alcohol, benzyl alcohol, linalool, and terpineol are preferred.

Component (b) may be used alone or in combination of two or more, and is 0.01 to 5.0% by weight, preferably 0.01% to 5.0% by weight, preferably 0.01% to 5.0% by weight in the composition.
Stone containing 03-1.0% by weight. This amount is 0.01wt
%, a sufficient addition effect cannot be obtained; on the other hand, 5.
If it exceeds 0w1%, the surface to be cleaned becomes sticky, which is not preferable.

The composition of the present invention is preferably slightly acidic with a pH of 3 to 6 in order to prevent rough hands and damage to tile joints.

Therefore, if the pH of the cleaning composition becomes high when hydroxy polycarminic acid is used as the component (B), it is preferable to adjust the pH to 3 to 6 with an alkaline agent such as hydroxide.

The composition of the present invention also contains 0. o~1s higher alcohol sulfate) salt, O+o~I8 alkylbenzene sulfonate, 08-w18 a-olefin sulfonate, 08~Ill higher al: I-, A, polyethylene glycol ether sulfate salt ( Bop=z
1-10% by weight of anionic surfactants such as
It is also possible to improve the detergency by adding a certain amount. Furthermore, the composition of the present invention contains an amphoteric surfactant, ethanol,
Hydrotropes such as ethylene glycol, bactericides, fungicides, chelating agents, rust preventives, abrasives, pigments, and the like can also be contained.

The composition of the present invention is usually used in the form of an aqueous solution and diluted under the conditions of use (with a component of about 0.5-2
It is appropriate to use it in an amount of 50 ppm, preferably 5 to 50 ppm.

Example 1 A cleaning agent having the composition shown in Table 1 was prepared, and its cleaning power, solvent odor, and hand roughness were evaluated according to the following criteria, and the results are summarized in Table 1.
