Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paste-like detergent for heavy dirt, and more specifically, it is a paste-like detergent that can be hung in the hand, rubbed in, and wiped off with a cloth such as a rag. The present invention relates to a dry paste detergent for heavy dirt that can effectively wash and remove heavy dirt such as machine oil that adheres to people's hands, that is, does not require the use of water.

Conventionally, hand-washing detergents used to clean oil stains from workers' hands during disassembly, assembly, maintenance and inspection of various machinery factories and machines have been made using kerosene as a paste and a surfactant such as soap. Alternatively, products containing a builder are used, but with conventional hand washing detergents of this type, even if degreasing is performed, there is a problem that the smell of kerosene and stickiness remain on the hands after washing.
In order to remove this, it is troublesome that it must be washed again using water.

There is also a powdered degreasing hand washing soap called perlite soap, but this has the disadvantage that water easily evaporates from the surface, and oil stains cannot be completely removed unless it is washed with water at the end. There are drawbacks.

Therefore, an object of the present invention is to provide a pasty detergent for heavy dirt that can completely remove heavy dirt such as machine oil from hands without using water. .

Another object of the present invention is to apply it to your hands and rub it in,
To provide a paste-like detergent for heavy dirt that can be effectively cleaned and removed by a simple operation of wiping with a cloth such as a waste cloth.

Still another object of the present invention is to provide a paste-like detergent for heavy dirt that can easily remove dirt from a wiping cloth such as a rag by simply washing with water.

According to the present invention, a heavy surfactant is characterized in that it consists of a paste-like material in which 5 to 35% by weight of synthetic zeolite powder and 5 to 25% by weight of sepiolite are blended into a concentrated aqueous solution of a surfactant. A soil paste detergent is provided.

The pasty detergent of the present invention is distinctive in that it contains both synthetic zeolite powder and sepiolite in a fixed ratio of amounts per concentrated aqueous detergent solution. The combination of synthetic zeolite powder and sepiolite maintains the detergent composition in the form of an easy-to-handle paste in the absence of external forces;
When taken out of the container and rubbed on the palm of the hand, it spreads well and has the property of blending well with heavy dirt such as machine oil on the hands. Moreover, the heavy dirt released from the surface of the hands by the action of the detergent is incorporated into the surface of the synthetic zeolite powder and sepiolite in the paste. This allows the removal of dirt and grime to be carried out effectively without leaving any discomfort on the hands. Furthermore, it is well known that synthetic zeolite powder exhibits excellent builder action during cleaning. In addition to exhibiting a preventive action), it also exhibits a so-called abrasive action when removing dirt, thereby completely removing heavy dirt. Furthermore, sepiolite is
It has an excellent thickening effect on concentrated aqueous solutions of surfactants, and is also effective in lifting dirt removed from the surface of the hands and preventing it from re-adhering.

In the present invention, the synthetic zeolite is A
Any synthetic zeolite powder such as type zeolite, type Silton B) manufactured by Kogyo Co., Ltd. is advantageously used.

Sepiolite, which is blended as the second component, is
It is a clay mineral mainly composed of crystalline magnesium silicate represented by Mg ₈ H ₂ (Si ₄ O ₁₁ ) _{3.3H 2} O. For example, it is commercially available from Takeda Pharmaceutical Co., Ltd. under the trade name AED+. .

The synthetic zeolite powder contains 5 to 35% by weight, especially 7 to 35% by weight of the surfactant concentrated Wednesday solution.
It is also important to use it at 20% by weight; if this amount is less than the above range, the various advantages mentioned above will not be obtained, and if it is more than the above range, it will be difficult to handle it as a paste, and it will be economically disadvantageous. is also disadvantageous.

In addition, sepiolite is contained in the concentrated aqueous solution in an amount of 5 to 25% by weight, particularly 7 to 18% by weight.
It is also important to use an amount below the above range and the desired thickening properties and other benefits mentioned above will not be achieved, while above the above range the formulation will become stiff and feel Otherwise, the cleaning action will be lost.

As a concentrated aqueous solution of surfactant, 5 to 50% by weight of one or a combination of two or more of various anionic, nonionic or amphoteric surfactants may be used.
A concentration of 10 to 40% by weight is used.

As surfactants, soaps, fatty acid mono- or diethanolamides, polyoxyethylene alkyl ethers, ethanolamine salts of polyoxyethylene alkyl ether sulfuric acid, polyoxyethylene alkyl phenols, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene glycerin fatty acids Examples include esters.

This concentrated aqueous solution contains propylene glycol,
It can contain a wetting agent such as glycerin and a sequestering agent such as sodium edetate and citric acid, and may further contain trace amounts of fillers, fragrances, colorants, antifungal agents, and the like.

The detergent of the present invention is in the form of a paste that is easy to handle, and can be filled into, for example, a tube container or other plastic squeeze container, and used for hand washing by workers in various factories, workplaces, etc.

The invention is illustrated by the following example.

Examples Concentrated aqueous surfactant solution ^* 76 parts Silton B 11 parts Adeplus 11 parts Silica (Carplex) 1.6 parts Fragrance Trace amount Antifungal agent Trace amount The above composition was kneaded in a vacuum pot to obtain a paste detergent. .

*For a concentrated aqueous surfactant solution, use the following formula: Triethanolamine salt of polyoxyethylene alkyl ether sulfate 16 Alkyl ether of polyoxyethylene 12.5 Diethanolamide of coconut oil fatty acid 4 Propylene glycol 2 Disodium edetate 0.2 Water Remaining amount I used something.

In order to test the cleaning power of the above detergent, after applying a mixture of 20% by weight of grease and 5% by weight of carbon black to waste engine oil on the hands, 2 to 5 g of the above detergent was applied to the palm of the hand. I took it and rubbed it evenly on my hands for 10 seconds. After that, when I wiped my hands with a rag, all of the oil stains were removed from my hands. When the used rag was washed with water without detergent, oil stains were completely removed from the rag.
