Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a container detergent composition in which a gel-to-paste detergent composition is filled in a tube container or a pump container.

[Prior Art/Problems to be Solved by the Invention] Detergents in various forms, such as powder and liquid, have been used in the past.

Powdered detergent is packaged in bags or boxes, but it is difficult to handle because of its small apparent specific gravity, and shipping costs are also relatively high.

On the other hand, in order to produce liquid detergents, the builder component, which is indispensable for its functionality, is solid, so it must be made into an aqueous solution containing less than 50% (by weight) of the active ingredient. At present, a uniform composition cannot be obtained and there are problems in handling.

Therefore, detergents for clothing, etc., filled in tube containers or pump containers are being considered, which have a higher concentration of detergent ingredients than liquid detergents and are compact and easy to handle. It has not yet been put into practical use.

[Means for Solving the Problems] The present invention solves the above-mentioned problems and provides a detergent composition which is compact, easy to handle, and whose quality does not easily change over time, and which is filled into a tube container or a pump container. It was developed for the purpose of providing a compatible solution to a dispersion of a nonionic surfactant that is fluid at room temperature and an organic sulfonate and/or an organic sulfate ester salt. The present invention relates to a container detergent composition in which a gel-like to paste-like composition containing the present invention is filled in a tube container or a pump container.

[Example] The nonionic surfactant having fluidity at room temperature used in the present invention preferably has a fluidity of 50 to
It is a nonionic surfactant with a viscosity of about 2000 ps, and is not particularly limited as long as it is commonly used for emulsification, dispersion, penetration, cleaning, solubilization, etc., and it can be used depending on the purpose of the detergent composition. They may be selected and used as appropriate.

Examples include adducts of ethylene oxide, propylene oxide, butylene oxide, etc. to alcohols, alkylphenols, fatty acids, and alkylamines; esters of sorbitan, sucrose, etc., and fatty acids having 8 or more carbon atoms. These nonionic surfactants may be used alone or in combination of two or more.

The content of the nonionic surfactant in the detergent composition is 1
0 to 60% is preferable, and 25 to 45% is more preferable. If the content is less than 10%, the apparent viscosity of the gelled product becomes high, making it difficult to squeeze it out of the tube. If it exceeds 60%, separation at high temperatures tends to occur.

The organic sulfonate and organic sulfate salt used in the present invention are components used as the main ingredient of detergents, and are not particularly limited as long as they are commonly used in laundry detergents and the like. They may be appropriately selected and used depending on the purpose. Among these, preferred are organic sulfonates such as alkylbenzene sulfonates, dialkylbenzene sulfone hydrochlorides, naphthalene sulfonates, and α-olefin sulfonates, alcohol sulfate ester salts, and alcohol ethylene oxide adducts. Examples include organic sulfate ester salts such as sulfate ester salts. These may be used alone or in combination of two or more. When an organic sulfonate is used, the detergency is enhanced, and when an organic sulfate salt is used, a detergent composition with good biodegradability and high safety can be obtained.

The content of the organic sulfonate and/or organic sulfate salt in the detergent composition is preferably 10 to 80%, more preferably 25 to 45%. The content is 1
If it is less than 0%, the cleaning effect tends to be insufficient, and 60%
If it exceeds , the gelling viscosity will be too high and it will be difficult to form a soft gel.

A specific example of the peroxide is sodium percarbonate, and the amount used in the detergent composition is usually 1.0 to 1.
4.0% is preferred.

Furthermore, components such as fragrances and coloring agents may be added, and the amount of these other components used is usually 1.0% in the detergent composition.
~4.0% is preferred.

Further, as the solvent, water, glycerin, ethylene glycol, diethylene glycol monobutyl ether, etc. can be used as appropriate.

The detergent composition filled in a tube container or a pump container in the present invention contains a compatible solution to a dispersion of the nonionic surfactant and a q-organic sulfonate salt and/or an organic sulfate salt; If so, it is a gel-like to paste-like composition containing the ingredients used. Note that the term "compatible material" to "dispersed material" refers to a state in which each component is homogeneously mixed, such as a component that is compatible with each other or a component that is homogeneously dispersed.

The detergent composition used in the present invention is in the form of a gel to paste, and each component may be compatible with each other or may be homogeneously dispersed. is preferable because it is difficult to separate.

There are no particular limitations on the material, shape, etc. of the tube container or pump container filled with the detergent composition, and for example, the following can be used.
