Description

  The present invention relates to a residential cleaning composition that can be widely used for residential use such as floors, walls, glass surfaces, home appliances, dining tables, kitchens, and the like, and can be cleaned only by wiping off dirt on the object to be cleaned.

  Conventionally, residential cleaners have been widely used for various purposes such as housing, furniture, glass, oil stains, toilets, and bathrooms. In particular, weak alkaline or alkaline synthetic detergents are the mainstream for use in residences, furniture, glass, and oil stains.

Examples of these alkaline region detergents include detergents composed of alkaline substances such as alkanolamines, zwitter detergent surfactants, anionic surfactants, and quaternary ammonium salts (see, for example, Patent Documents 1 and 2). Are known.
In addition, for use in places where it cannot be poured with water, such as outside of homes, furniture, glass, oil stains, toilets and washstands, dilute the cleaning agent in water and use a rag or mop to wash There are two types of cleaning agents on the market: a dilution type that wipes off dirt that has adhered, and a spray type that sprays directly on the object to be washed or sprays on a cloth to wipe off dirt adhering to the object to be washed. Recently, a spray type cleaning agent using a trigger container which is easy to use has become mainstream.

  With regard to the performance of these household cleaners, it is important to have a cleaning power that removes various types of dirt in the home and that there is no wiping residue or stickiness after use. There are many detergents on the market that recalled “no need to wipe twice” rather than having a solid surface.

  However, these detergents including the above-mentioned documents 1 and 2 use an alkaline substance such as alkanolamine and a surfactant such as a zwitter detergent surfactant, an anionic surfactant, and a quaternary ammonium salt as a cleaning component. There are many things that are used, and the surface to be cleaned is always wiping as a null-null, and the usability is very poor by attaching a null when touching the hand skin. There is a problem that it is insufficient in terms of usability to do.

  Therefore, in order to easily and easily wipe with a tissue paper when you notice dirt, not only is the cleaning power high, but the cleaning surface will never stick to the skin and you can touch your skin. It is thought that it is important to reduce the amount of the cleaning agent with a null due to inevitable reasons.

In the field of detergents, those that are superior in detergency and that the skin of the hands does not become null when used include, for example, specific fatty acids or derivatives thereof, specific sugar fatty acid ester surfactants, ethers A liquid detergent composition (see, for example, Patent Document 3) that is suitable as a kitchen detergent, a face wash, or the like formed by using a carboxylic acid or a salt thereof together is known.
However, the liquid detergent composition described in this document 3 has a high surfactant concentration and is used in a usage method in which it is washed away with water, and is not suitable for use as described above.

In addition, in the field of residential detergents, as examples of appealing that the cleaning surface and hand skin are not nullified, for example, surfactants, lower alcohols, and chelating agents in each specific range. Although the neutral liquid detergent composition contained (refer patent document 4) is known, this detergent composition is a technique in a neutral detergent, and the consideration with respect to the anti-null technique regarding an alkaline detergent is still There is a problem in the point which is not enough.
In addition, as for pH indication of synthetic detergent in household goods quality indication method, neutrality is pH 8.0 or less 6.0 or more, weak alkalinity is pH 11.0 or less exceeding 8.0, alkalinity exceeds pH 11.0 The pH range defined in this patent is weakly alkaline and partly alkaline.
Japanese Patent Laid-Open No. 3-41200 (Claims, Examples, etc.) JP-T-5-503547 (Claims, Examples) JP-A-5-255694 (Claims and Examples) JP 2000-129292 A (Claims, Examples)

  The present invention has been made in view of the above-mentioned problems and the current state of the prior art, and is intended to solve this problem. When a stain is noticed, when the object is wiped directly or by spraying on a wiping tool, the surface to be washed is always nullable. As well as avoiding the situation where the wiping efficiency is poor, it has a comfortable feeling that there is no null even if you accidentally touch the hand skin, and it has excellent cleaning power against various dirt such as oily and aqueous dirt, dark dirt, floor, It aims at providing the cleaning composition for residence suitable for a wall, a glass surface, a household appliance, a dining table, the kitchen periphery, etc.

  As a result of intensive studies to solve the above-described conventional problems, the present inventors have found that the conditions of the solution in which the dielectric constant (εr) of the water / solvent mixture at a temperature condition of 25 ° C. is a specific value or less. Then, by containing alkali agent, surfactant and chelating agent in a specific range as cleaning components, and adjusting the pH to a specific range, the cleaning surface can be directly sprayed or wiped with a wiping tool. With just an operation, it has excellent cleaning power for oily and aqueous stains and darkening stains, and the cleaning surface will never be squeezed indefinitely. The present inventors have found that the above-mentioned residential detergent composition for the purpose of being free from a null can be obtained, and the present invention has been completed.

  That is, according to the present invention, (a) the water / solvent mixture has a dielectric constant (εr) of 70 or less at a temperature condition of 25 ° C., and (b) an alkali agent of 0.001 to 3.0% by mass, c) containing 0.001 to 5.0% by mass of a surfactant and (d) 0 to 5.0% by mass of a chelating agent and having a pH exceeding 8.0 and not exceeding 12.0. It is a cleaning composition for dwellings characterized by adjusting.

  According to the present invention, it can be widely used for dwellings such as floors, walls, glass surfaces, home appliances, dining tables, kitchen areas, etc. In addition, it has excellent detergency for dark stains, the cleaning surface will not linger forever, cleaning efficiency is improved compared to conventional wiping cleaning, and even if it accidentally gets on the hand skin, it is residential cleaning An agent composition is provided.
