Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to cleaning agents for use in cleaning hard surfaces. More specifically, the present invention relates to hard surface cleaning agents containing polyoxyethylene dicarboxylic acids.

[Conventional technology]

Glass in ventilation fans, ovens, bathtubs, tiles, toilet bowls, etc.
Stains on hard surfaces made of metals, ceramics, and resins include oils, fats, and various organic substances that have been altered by heat or air, become resins, and adhered, and paints and inks that have formed resin coatings. There is. Since neutral detergents such as kitchen detergents have weak cleaning power, it has been difficult to remove stains that have adhered to hard surfaces. Therefore, in order to remove such stains from hard surfaces, there are methods to increase the cleaning power by adding acid or alkaline substances to the cleaning agent to make the pH strong alkaline or acidic, or using ethylene glycol ether solvents, acetone, etc. , a method of adding chlorinated solvents has been used. Among the conventional methods, adding sodium hydroxide or hydrochloric acid to make the cleaning agent strongly alkaline or acidic requires wearing rubber gloves because the cleaning agent irritates the skin, and depending on the type of hard surface. has the disadvantage of being corroded. In addition, engineered ethylene glycol ether solvents,
Although cleaning agents containing acetone, xylene, and chlorinated solvents have some degree of cleaning power, some solvents are highly toxic to the human body, highly volatile, and highly flammable, so they should not be used. It cannot be said that it is preferable. In particular, products containing ethylene glycol ether-based water-soluble solvents have a strong irritating odor, so the odor is bothersome during use, and furthermore, when scented, the desired scent cannot be obtained.

[Problem to be solved by the invention]

An object of the present invention is to provide a hard surface cleaner that has strong cleaning power and is low in toxicity, low irritation, and low odor.
