Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hard surface cleaning composition, and more particularly, to a hard surface such as tiles, enamel, etc. around the kitchen where oil scattered by cooking in the kitchen is deteriorated by heat or aging. Stubborn stains such as oil stains can be effectively and safely removed, and cleaning can be done quickly.

2. Description of the Related Art Dirt that is difficult to remove due to oil, that is, modified fat and oil stains, is attached to a ventilation fan, a gas range, etc. of a kitchen in a general household. This stain is a stain that adheres to the ventilation fan or the gas range when the tempura, stir-fried food, or the like is cooked, oil scatters, or flies as oil smoke. In general,
Many of the oils used in edible oils have an unsaturated chemical structure with double bonds, and such oils are easily oxidized when exposed to the air for a long time and subjected to heat or light. Or it polymerizes and changes into a thing with a large molecular weight, and comes to show a resin state. This is the content of the modified oil and fat stains and causes stains that are difficult to remove.

Also, in a ventilation fan in a general household, the amount of oil stains increases and the appearance becomes unsightly in about 6 months after the oil starts to be put in without care. By this time, the denaturation of the oil had progressed considerably, and the adherence to the substrate became stronger and the stain became hard to remove. To remove such stains, a special cleaning agent containing an alkylene glycol ether solvent such as butyl carbitol was used. However, these solvents are
There are problems in terms of safety, odor, solvent properties, cleaning effect, etc.

Therefore, as a detergent composition for solving the above-mentioned problems, in JP-A-51-10808, it is possible to increase the detergent power by using hexylene glycol in combination with an alkylene glycol ether solvent. A safe detergent composition is described which is capable and substantially odor free. In addition, Japanese Patent Publication No. 62-501570 discloses that by containing a glycoside surfactant, an alkylene glycol alkyl ether solvent and a cleaning agent, it has excellent cleaning properties and leaves an unsightly residual film after cleaning. A liquid detergent composition that does not exist is described. However, these detergents have not been sufficiently satisfactory for persistent oil and fat stains, especially modified oil and fat stains modified by the influence of temperature, humidity, light, oxygen, microorganisms and the like.

Therefore, it is an object of the present invention to control temperature, humidity,
It is an object of the present invention to provide a hard surface cleaning composition which is excellent in cleaning power and foaming power against stubborn dirt such as oily dirt modified by the influence of light, oxygen, microorganisms and the like and which can be quickly cleaned.
