Description

[Technical Field]

[0001] The present invention relates to a liquid cleaning agent. [Background technology]

[0002] Generally, liquid compositions such as liquid detergent compositions (such as kitchen detergents, liquid laundry detergents, and body cleansers) and liquid cosmetics are packed in containers and shipped in a manner that protects them from the outside air. However, when a consumer uses the composition, the lid of the container is opened and closed, bringing the composition into contact with the outside air. Therefore, when the liquid composition is used, it is unavoidable that microorganisms and the like may be mixed in from the external environment. If the liquid composition is contaminated with microorganisms and has a weak preservative effect, it may cause secondary contamination such as spoilage, which may not only cause discomfort to the user due to the generation of an unpleasant odor or deterioration in color, but may also cause harm. To prevent such secondary contamination, it is necessary to incorporate an isothiazolinone-based preservative into the liquid composition to create a composition with preservative effect (Patent Document 1).

Another example is a method in which the liquid detergent is dissolved in water in advance to prepare a cleaning solution, and then the items to be washed are immersed in this cleaning solution. Alternatively, the liquid detergent can be directly applied to the items to be washed, left for a certain period of time, and then washed normally (application washing). It is also preferable to use a washing machine equipped with an automatic detergent dispensing function, which has recently become practical. The automatic detergent dispensing function automatically dispenses detergent from a tank containing the detergent into the washing tub via a dispensing pipe. A measuring device such as a syringe pump is installed in the dispensing pipe, allowing a fixed amount of detergent, set according to the amount of laundry, to be transferred from the tank to the washing tub. Examples of items to be washed include textile products such as clothing, dishcloths, towels, and sheets. These textile products may be made from natural fibers including plant fibers such as cotton and hemp, and animal fibers such as wool and silk, or from chemical fibers such as polyester and nylon, and are not particularly limited. The liquid detergent is suitable as a liquid detergent for textile products. When the liquid detergent is used by dissolving it in water, it is preferably diluted, for example, 5 to 5000 times (by volume). [Example]
