Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to glass products and products partially using glass;
Sprinkle directly on light stains such as plastic products, steel products, furniture, electrical appliances, desks, chairs, floors, windows, etc.
Or it relates to a household cleaning agent that removes dirt by spraying and wiping.

[Conventional technology]

Glass products and products that partially use glass, plastic products, steel products, furniture, electrical appliances, desks, chairs,
Dirt on household items such as floors and windows is mainly caused by sand, dust, oil, and grease.
Fatty acids or these stains are weakly modified molecules. Cleaning agents for removing these stains usually consist of a combination of surfactants, solvents, alkaline agents, and the like.

[Problem that the invention seeks to solve]

However, since the target is household goods, it is necessary to prevent the cleaning agent components from remaining on the surfaces of these household goods and causing cloudiness or susceptibility. It has been difficult to use the ingredients at concentrations that will provide sufficient detergency. Further, alkaline agents require the use of volatile substances for the same reason, and also cannot be used in high concentrations due to safety concerns for the human body when applied to the eyes or skin.

In order to improve the cleaning power, volatile solvents are mixed with these surfactants and alkaline agents. These solvents include lower alcohols such as ethanol and isopropanol, and ethylcerone lubricant.
Combinations of ethylene glycol derivatives such as butyl cellosolve have been used. However, even with the addition of these solvents, satisfactory cleaning power has not been obtained, and cleaning agents containing these solvents have not been used by sprinkling them on the surfaces of household items, or by using rags, rags, paper towels, etc. −
When a user performs the task of wiping with a towel or the like, the friction between the cloth, paper, e-type used for wiping and the surface of the household goods becomes large, resulting in the inconvenience that wiping is difficult. In the prior art, a slip improver such as polymethylsiloxa Z is added to solve this problem. However, this slip improver remains on the surface of the base material, causing new disadvantages such as clouding and making the surface of household products more susceptible to slipping.

As described above, a residential cleaning agent that has strong cleaning power, does not cause fogging after cleaning, and solves the problem of workability has not yet been obtained.

[Means for solving problems]

As a result of intensive research aimed at solving the problems mentioned above, the present inventors have discovered that by using a specific solvent and a compound in combination, it is possible to satisfy both cleaning performance and workability at the same time. completed.

That is, the present invention provides a residential cleaning agent characterized by containing propylene glycol monomethyl ether and N-acylsarcosine salt as essential ingredients.

The salt of N-acylsarcosine is preferably a sodium or potassium salt, and the acyl group has 6 to 22 carbon atoms.
Branched or linear ones are preferred. The formulation t of the salt of N-acylsarcosine is o, oi to 1% by weight (hereinafter %
) is preferred. If it is less than 0.01%, no effect can be obtained, and if it exceeds 1%, it is not preferable as it may cause back-scraping on household goods.

Propylene glycol monomethyl ether (hereinafter abbreviated as PGME), which is another essential component of the present invention, is used as a solvent for the N-acyl sarcosine salt and other components contained in the detergent of the present invention. PGME improves cleaning power and is volatile with a boiling point of about 120° C., so it does not leave any residue or cloud on the surfaces of household products. It also has the effect of significantly reducing the frictional force on the surface of household goods.

The blending amount of PGMI is not particularly limited, but is 10.1 to 2.
0%, especially 0.1-8% is preferred.

In the cleaning agent of the present invention, the solvent PGM'F alone can exhibit excellent effects, but it is also possible to use ethanol and/or isopropanol in combination. The blending amount of these solvents is 0.1 to 15%, respectively.
, particularly preferably 0.1 to 8%. These solvents are used for purposes such as adjusting the volatilization rate and the viscosity of the cleaning agent stock solution, and the optimum viscosity, Can be adjusted to the optimum volatilization rate.

Although not essential components in the present invention, surfactants, alkaline agents, chelating agents, rust preventives, and the like may be added.

Examples of surfactants include fatty acid salts, sodium or potassium salts (sodium, potassium, ammonium, and alkanolamine salts of alkyl sulfates, regardless of the fatty acid number of carbon atoms 8 to 22, with or without branching, and with or without unsaturated oro bonds). (The same applies to the following alkyl groups, where the alkyl group has 8 to 22 carbon atoms, regardless of whether or not it is branched or has an unsaturated bond), sodium or potassium salt of alkylbenzenesulfonic acid, sodium or potassium alkylnaphthalenesulfonate, Sodium sialkylsulfosuccinate, sodium alkylzophenyl ether sulfonate, sodium, potassium, ammonium or alkanolamine salt of polyoxyethylene alkyl ether sulfate (polymerization degree of oxyethylene is 3 to 100, the same applies to the following polyoxyethylenes) Anionic surfactants such as polyoxyethylene phenyl ether sodium sulfate; , trifatty acid ester, glycerin fatty acid ester, polyoxyethylene fatty acid ester,
Nonionic surfactants such as can be used.

These surfactants can be used as -t1 or a combination of two or more types, but due to the problem of residue 9 on the surfaces of household products, it is preferable to use the total amount in a range of 2% or less.

Any known alkaline agent can be used, but volatile ones are preferred because of the problem of residual residue on the surfaces of household goods.

Examples include alkanolamines, ammonia, and morpholine. These surfactants and alkaline agents are used for the purpose of improving cleaning power.

Chelating agents are used for the purpose of sequestering all polar ions in water when compounding cleaning agents or when diluting cleaning agents, and are inorganic salt compounds that have chelating ability. All can be used, including citric acid, sodium ethylenecyaminetetraacetate, phosphates, borates, etc. These chelating agents serve to prevent the formation of compounds that would otherwise leave residue on the surfaces of household items such as metal soaps during cleaning. The amount used is preferably in the range of 0 to 1%.

When using the cleaning agent of the present invention in the form of an aerosol, compounds such as sodium silicate, ammonia, sodium benzoate, sodium nitrite, benzotriazole, and benzothiazole are used as rust preventive agents to prevent can corrosion. can do.

In addition, small amounts of antibacterial agents, dyes or pigments, fragrances, etc. may be added depending on the purpose.

〔Effect of the invention〕

The cleaning agent of the present invention can remove sand, dust, oil and fat from various household products.
It not only has very good cleaning power against stains such as fatty acids, or those that have been weakly modified and polymerized, but also has excellent cleaning power against stains that have been slightly strongly modified and polymerized. have In addition, there is no residue or cloudiness of the cleaning agent components of the present invention on the surfaces of household goods. Furthermore, the friction between the cloths used for wiping 9 and the surface of the household goods sprinkled or sprayed with the cleaning agent of the present invention is very small, so the user can easily wipe it off. It also has operational advantages.
