DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition for modified oils and fats, and more particularly, to oils scattered by cooking in a kitchen, which are deteriorated by heat or aging, and are used for tiles and enamels around the kitchen. The present invention relates to a modified oil and fat cleaning composition which effectively and safely removes stubborn stains such as oil and fat stains adhered to a hard surface, and has excellent foaming properties and low-temperature storage stability.

2. Description of the Related Art Dirt which is hard to remove due to oil, that is, denatured grease, adheres to a ventilation fan, a gas range, etc. of a kitchen in a general household. This dirt is a dirt that is scattered around when cooking tempura, stir-fry, or the like, or flies as oil smoke and adheres to the ventilation fan or the gas range. In general,
Many of the oils used in edible oils have an unsaturated chemical structure with double bonds. Such oils are easily oxidized when exposed to air for a long time and under the action of heat or light. Or polymerizes, and changes into a large molecular weight one, and becomes resinous. This is the content of the denatured oil and fat stain, and causes the stain that is difficult to remove.

[0003] In addition, if a ventilation fan in a general household is not cleaned, the amount of oil stains increases and the appearance becomes unsightly in about six months after the oil starts to be applied. At this time, the denaturation of the oil has progressed considerably, and the oil adheres to the substrate strongly, resulting in dirt that is difficult to remove. In order to remove such stains, a special detergent containing an alkylene glycol ether-based solvent such as butyl carbitol has been used. However, these solvents
There are problems in safety, odor, solvent properties, cleaning effect, and the like.

Further, as a detergent composition which solves the above-mentioned problems, Japanese Patent Application Laid-Open No. 51-10808 discloses a method for increasing the detergency by using hexylene glycol in combination with an alkylene glycol ether solvent. Can,
A safe cleaning composition with substantially no odor is described. However, this detergent composition was unsatisfactory for stubborn stains such as denatured oil and fat stains, and was not yet sufficiently satisfactory particularly in terms of low-temperature stability.

Accordingly, an object of the present invention is to provide a temperature, humidity,
An object of the present invention is to provide a detergent composition for a modified oil and fat stain excellent in detergency, foaming power and low-temperature storage stability against stubborn stains such as oil and fat stain modified by the influence of light, oxygen, microorganisms and the like.

[0006]

As a result of various studies, the present inventors have found that a mixture of at least two specific alkylene glycol ether-based solvents can be added to a nonionic surfactant or an amphoteric surfactant. It has been found that a detergent composition containing an amine compound and a specific acid can achieve the above object.
