Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a detergent composition for modified oil and fat stains, more specifically, oil scattered by cooking in the kitchen is deteriorated by heat or aging, so that tiles around the kitchen, enamel, etc. Effectively and safely removes stubborn stains such as oil stains attached to hard surfaces.
The present invention also relates to a hard surface cleaning composition which is free from odor deterioration and coloration over time.

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, the solvent blended with these detergents has problems in terms of safety, odor, solvent property, cleaning effect and the like.

As a solvent for solving the above problems,
Japanese Patent Application Laid-Open No. 1-236300 describes a polyoxyalkylene monobenzyl ether solvent, which is excellent in solvent odor and safety according to the description of the publication. However, with the above solvents,
A sufficiently satisfactory composition cannot be obtained in terms of foaming power when sprayed. Furthermore, a compounding system which does not cause deterioration of odor or coloring particularly when stored for a long period of time when stored in this solvent system for a long time has not yet been obtained.

Therefore, it is an object of the present invention to control temperature, humidity,
Cleaning power for stubborn stains such as oil stains modified by the influence of light, oxygen, microorganisms, etc., in particular, it has excellent foaming power and has no odor deterioration or coloration when stored for a long period of time. To provide an agent composition.
