Description

Liquid Cleaner Composition {LIQUID CLEANER COMPOSITION}

The present invention relates to a liquid detergent composition, and more particularly, to a liquid detergent composition having excellent cleaning power against contamination of residential spaces, especially stray soil that has been left unattended for a long time.

In general, the pollution of the living space is easily removed with a general cleaning agent, but in the case of oil pollution in the kitchen, if left for a long time, it is oxidized by air or light and is not easily removed because the oil pollution is denatured.

Conventionally, cleaning agents containing a surfactant and an alkali agent are mainly used to remove oil contamination as described above. However, the cleaning agent containing the above components has excellent cleaning power against light contamination in which oil contamination has not been left unattended for a long time, but has a problem in that cleaning power for poor contamination left unattended for a long time is insufficient.

Therefore, there is a need for further research on a detergent having excellent cleaning power against long-term neglected contamination.

In order to solve the problems of the prior art as described above, an object of the present invention is to provide a liquid detergent composition with a significantly improved cleaning power for pollution of the living space, in particular, long-term neglected contamination.

In order to achieve the above object, the present invention provides a liquid detergent composition,

a) 0.5 to 20% by weight fat-soluble solvent;

b) 0.5 to 20% by weight of a water-soluble solvent;

c) 0.1 to 7% by weight penetrant;

d) 0.1 to 10% by weight of alkaline agent;

e) 0.1 to 15% by weight of surfactant;

f) 0.1 to 2 weight percent of chelating agent; And

g) remaining water

It provides a liquid detergent composition comprising a.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention, while studying a detergent that has excellent cleaning ability against long-term uncleaned contamination, and produced a liquid detergent using a mixed solvent and a penetrant mixed with a fat-soluble solvent and a water-soluble solvent, contaminated the living space, in particular, long-term It was confirmed that the cleaning power for the tainted contamination was significantly improved, and based on this, the present invention was completed.

The liquid detergent composition of the present invention is 0.5 to 20% by weight fat-soluble solvent, 0.5 to 20% by weight water-soluble solvent, 0.1 to 7% by weight penetrant, 0.1 to 10% by weight alkaline agent, 0.1 to 15% by weight surfactant, 0.1 to chelating agent 2 wt%, and a residual amount of water.

The fat-soluble solvent of a) used in the present invention is ethylene glycol monohexyl ether, diethylene glycol monohexyl ether, ethylene glycol monophenyl ether, propylene glycol monobutyl ether, dipropylene glycol monobutyl ether, or propylene glycol monophenyl ether. Etc. can be used.

The oil-soluble solvent is preferably contained in 0.5 to 20% by weight, more preferably 1.0 to 15% by weight in the liquid detergent composition. If the content is less than 0.5% by weight, the effect on contamination is insignificant, and when it exceeds 20% by weight, there is a problem in that it is inefficient because the dissolution and decomposition effects on the pollution are insignificant compared to the amount used.

As the water-soluble solvent of b) used in the present invention, it is preferable to use 3-methoxy-3-methyl-1-butanol represented by the following formula (1).

In general, the water-soluble solvent used in the liquid detergent is mainly used ethylene glycol alkyl ethers (4 to 8 carbon atoms), there is a problem that gives a discomfort during use because the smell is very irritating.

However, the 3-methoxy-3-methyl-1-butanol has a low flash point of 71 ° C. and a boiling point of 174 ° C., which is less affected by temperature, has excellent solubility in water, and is similar to ethylene glycol alkyl ethers. It has physical properties and is a colorless and odorless solvent, which has the advantage of excellent use.

The water-soluble solvent is preferably contained in 0.5 to 20% by weight, more preferably 1.0 to 15% by weight in the liquid detergent composition. If the content is less than 0.5% by weight, the effect on contamination is insignificant, and when it exceeds 20% by weight, there is a problem in that it is inefficient because the dissolution and decomposition effects on the pollution are insignificant compared to the amount used.

The fat-soluble solvent and the water-soluble solvent as described above are preferably mixed in a mixing ratio of 1:15 to 2: 1, more preferably in a mixing ratio of 1:10 to 1: 1. When the water-soluble solvent is used alone or when the mixing ratio of 1: 15 is used in comparison with the oil-soluble solvent, there is a problem in that the dissolving ability to oil-soluble oil pollution is lowered, and the oil-soluble solvent is used alone or as compared to the water-soluble solvent. When used in excess of the 2: 1 mixing ratio, there is a problem that the solubility is lowered and the phase stability is poor.

The penetrant of c) used in the present invention acts to increase the penetration force between the oil contamination and the surface when the stuck oil pollution is attached to the surface.

The penetrant may be N-alkylpyrrolidone such as N-octylpyrrolidone or N-dodecylpyrrolidone.

The penetrant is preferably included in 0.1 to 7% by weight, more preferably 0.2 to 5% by weight in the liquid detergent composition. When the content is less than 0.1% by weight, the effect of improving the penetration between oil contamination and the surface is insignificant, and when the content is more than 7% by weight, there is a problem in that it is economically insignificant.

The alkali agent of d) used in the present invention may be an inorganic alkali agent or alkanol amines as a fine preparation for contamination. Specifically, the inorganic alkali agent may be used sodium hydroxide, potassium hydroxide, sodium metasilicate, and the like, and the alkanol amines may be used monoethanol amine, diethanol amine, or triethanol amine. The alkali agents may be used alone or in combination, and it is particularly preferable to use alkanol amines.

The alkali agent is preferably included in 0.1 to 10% by weight, more preferably 0.2 to 5% by weight in the liquid detergent composition. If the content is less than 0.1% by weight, it is difficult to exhibit satisfactory cleaning power, and when the content is more than 10% by weight, there is a problem in that it is uneconomical because the effect of the amount of use is insignificant.

The surfactant of e) used in the present invention functions to wash the oil contaminated, disperse emulsion, sterilize.

Anionic surfactant, nonionic surfactant, or cationic surfactant can be used for the said surfactant, These can be used individually or in mixture of 2 or more types. In particular, it is preferable to use a cationic surfactant for bactericidal action.

The anionic surfactant may be an alkyl sulfate, an alkyl polyoxyethylene sulfate, an alpha-olefin sulfonate, a fatty acid salt, or the like. The salt of the anionic surfactant may be sodium or potassium. The nonionic surfactant may be polyoxy ethylene alkyl ether, polyoxy ethylene phenyl ether, fatty acid diethanol amide, or the like, and the cationic surfactant may be alkyl dimethyl benzyl ammonium chloride.

The surfactant is preferably included in 0.1 to 15% by weight, more preferably 0.5 to 10% by weight in the liquid detergent composition. If the content is less than 0.1% by weight, the effect is insignificant, and if it exceeds 15% by weight, excessive bubbles are generated, and there is a problem in that rinsing property is lowered.

The chelating agent of f) used in the present invention functions to ion-block the metal ions present in water. The chelating agent may use EDTA-4Na or EDTA-2Na.

The chelating agent may be included in the liquid detergent composition in an amount of 0.1 to 2% by weight for ion collection of metal ions present in water.

In addition, in addition to the above components, the liquid detergent composition of the present invention may use auxiliary components such as fragrances and dyes that are commonly used in liquid detergents.

The liquid detergent composition of the present invention composed of the above components has an advantage of excellent cleaning power against contamination of residential spaces, in particular, soiling left unattended for a long time.
