Description

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.
The present invention relates to a hard surface cleaning composition excellent in foamability.

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 to change to a polymer having a large molecular weight, and becomes resin-like. 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 cleaning composition containing an alkylene glycol ether solvent such as butyl carbitol has been used. However, these detergent compositions have problems in terms of odor, cleaning effect and the like.

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 which is made and is substantially odor free is described. Further, JP-A-1-236300 describes a hard surface cleaner containing a polyoxyalkylene monobenzyl ether in which the number of moles of polyoxyalkylene added is 5 mol or less. According to the description of the publication, it is excellent in foaming. However, these detergents are still not sufficiently satisfactory for persistent oil and grease stains, especially for oil and fat stains modified by the influence of temperature, humidity, oxygen and the like.

Therefore, an object of the present invention is to provide a hard surface cleaning agent which is excellent in swelling power and cleaning power for stubborn dirt such as oil stains modified by the influence of temperature, humidity, oxygen and the like, and which enables quick cleaning. To provide a composition.
