Multipurpose Cleaner Composition

Detailed description of the invention

[Purpose of invention]

The present invention relates to a multi-purpose detergent composition for removing contamination of the living space. More specifically, the present invention relates to a multi-purpose detergent composition which improves the cleaning ability against contamination and at the same time improves the bubble control generated during rinsing.

TECHNICAL FIELD OF THE INVENTION

Conventional multipurpose detergent compositions often contain a surfactant and an organic solvent for cleaning. However, it has a disadvantage of strong odor when using organic solvents, amine compounds, and ammonia water having an irritating odor (see US Patent No. 4576738) and has a problem in that continuous bubbles are generated by the surfactant during rinsing.

[Technical task to achieve the invention]

The present inventors have conducted numerous studies and experiments to compensate for the above-mentioned disadvantages of the prior arts, and as a result, a multi-purpose containing a bubble control agent to improve the bubble control during rinsing, an anion and nonionic surfactant and an organic solvent to improve the cleaning power Detergent compositions have been developed.

[Configuration and Function of Invention]

The present invention contains 0.5 to 10% by weight of anionic and nonionic surfactants, 0.2 to 2.0% by weight of fatty acids having 10 to 18 carbon atoms, and 1.0 to 20% by weight of N-methyl-2-pyrrolidone organic solvent as a bubble control agent. It relates to a multi-use cleaning composition, characterized in that.

In the present invention, anionic and nonionic surfactants are used to emulsify and disperse the cleaned and degraded contamination, and it is appropriate to use 0.5 to 10% by weight of the used amount. When the anionic and nonionic surfactant is used at 0.5 wt% or less, the emulsification and dispersion ability of the contamination is insufficient, and when 10 wt% or more is used, excessive bubble generation occurs.

In the present invention, an anionic surfactant may be a (C ₁₂ -C ₁₈ ) higher alcohol sulfate system (-OSO ₃ Na), a (C ₁₂ -C ₁₈ ) alkylbenzenesulfonate system (-SO ₃ Na), or the like. Nonionic surfactants are polyoxyethylene glycol forms of ethylene oxide addition (EO = 5-16) of higher fatty acids (C ₁₂ -C ₁₆ ), polyoxyethylene glycol forms of fatty acid esters of aliphatic amides, fatty acids of sorbitol and sorbitan Ester forms, aliphatic amide forms of alkanolamines, and the like.

The organic solvent used in the present invention is a compound having the function of penetrating and decomposing pollution and having the following structural formula.

(N-methyl-2-pyrrolidone)

The solvent has a flash point of 93 ℃, a boiling point of 202 ℃, a freezing point of -29.4 ℃, and a surface tension of 40.7 dyne / cm, which has little effect on temperature, so it can be used in a wide range and has excellent solubility in water. It is a hypoallergenic solvent with very good properties.

It is preferable to use 1.0-20 weight% of N-methyl- 2-pyrrolidone solvent in the cleaning composition of this invention. If the organic solvent is used at less than 1.0% by weight, the removal effect of the contamination is weak, and when used at more than 20% by weight, there is no disadvantage, but unnecessary use is required.

In the cleaning composition of the present invention, it is preferable to use a fatty acid having 10 to 18 carbon atoms as a bubble control agent for controlling bubbles during rinsing. Fatty acid is used in 0.2 to 2.0% by weight, when used in less than 0.2% by weight is less foam control ability when rinsing and use more than 2.0% by weight has no disadvantages, but use unnecessary.

In addition, in the cleaning composition of the present invention, a neutralizing agent is used to neutralize the acidic anionic surfactant and fatty acid, and the amount thereof is preferably 0.1 to 2.0% by weight. If the neutralizing agent is used in less than 0.1% by weight, the neutralization is not good, and when it is used in more than 2.0% by weight, it is strongly alkaline and irritating to the human body.

In addition, in the cleaning composition of the present invention, 0.5 to 5.0% by weight of monoethanolamine is used as the fineness aid. When the monoethanolamine is used at 0.5% by weight or less, it does not function as a fine preparation, and when used at 5.0% by weight or more, it is strongly alkaline and irritating to the human body.

A chelating agent that collects ions present in water is used at 0.1 to 5.0 wt%. The chelating agent uses EDTA-4Na (tetraacetic acid-4Na with ethylenedinitrile), EDTA-2Na, and the like. The chelating agent is less effective when used at less than 0.1% by weight and unnecessary when used at 5% by weight or more.

It is preferable to contain 0.01 to 1.0% by weight of dyes, preservatives, fragrances, etc. as other adjuvants. Other weight percentages consist of water.

Hereinafter, although this invention is demonstrated in detail based on an Example, the technical scope of this invention is not limited to these.

[Examples and Comparative Examples]

Next, the components of the composition contents shown in Tables 1 and 2 were sequentially added to water, followed by complete stirring to prepare a multipurpose cleaner after complete dissolution. When neutralizing lauryl acid, the temperature is heated to 60 ° C. In the following Tables 1 and 2, the anionic surfactant is (C ₁₂ -C ₁₈ ) alkylbenzenesulfonate, and the nonionic surfactant is polyoxyethylene glycol of ethylene oxide addition (EO = 7-9) of fatty acid (C ₁₂ ). The chelating agent is EDTA-4Na, and other auxiliary agents are dyes, preservatives, and flavors.

TABLE 1

(Unit: weight%)

TABLE 2

(Unit: weight%)

The following evaluation was carried out using the cleaning composition in Examples and Comparative Examples shown in Tables 1 and 2 above.

1) Evaluation method of bubble control ability during rinsing

1 g of each composition is added to a 250 ml cylinder and then 100 ml is filled with water.

Insert the cylinder into the cleaning solution mixer, which is its own laboratory equipment, and rotate the cylinder 30 times in the vertical direction (360 degrees). After the rotation, the initial bubble height generated in the cylinder and the bubble height after 10 minutes are measured. Repeat this process three times to calculate the average value.

As described above, by measuring the bubble height of the 1.0% solution of each composition, it is possible to indirectly determine the degree of bubble generated when rinsing.

2) strong odor response evaluation method

It is evaluated by the smell felt while wiping the 50 × 50cm grain surface in a confined space of 1 pyeong.

If smell of solvent is strong: X

If the smell of solvent is not smelly or felt: ○

3) Evaluation method of cleaning of contamination

-Contamination solution

Dissolve 10g of boiled oil, 10g of pork oil and 10g of soybean oil in 70g of chloroform and store it in a glass container.

Pollution Specimen Fabrication

2 × 6cm of glass surface is completely immersed in the manufacturing contaminant, then taken out and dried in a natural state to make a contaminated specimen.

Dip the above contaminated specimens into each composition solution for about 30 seconds and visually identify them.

When peeling of the contamination layer is less than 50%: X

When 50% or more of the contaminants come off: ○

The test results are shown in Table 3.

TABLE 3

As can be seen from the test results of Table 3, in the composition of Example 1-5, containing the fatty acid as the bubble control agent can be confirmed that the bubble control ability is excellent because the bubble degree is significantly reduced after rinsing, odorless solvent Although the fragrance test and the contamination cleaning test showed excellent results, the composition of Comparative Example 2 contained strong fragrance solvent, but it had excellent staining power but strong solvent fragrance. Bubbles were generated and there was no bubble control ability, and in Comparative Example 4 composition, the solvent-free pollution staining power was weak.

As can be seen from the above, the present invention is excellent in the ability to clean the pollution of the residential space, but does not have a strong smell, it can be seen that a multi-purpose detergent composition in which bubbles are generated even when rinsing.
