Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid detergent composition used for dry cleaning of textiles such as clothes, and more specifically, to remove water-based stains and stains which are difficult to remove by washing prior to dry cleaning. The present invention relates to a liquid detergent composition used when performing a brushing treatment or the like for cleaning.

2. Description of the Related Art Conventionally, in dry cleaning using a petroleum-based solvent, it is difficult to remove water-soluble stains and stains such as sweat stains and food stains by ordinary washing. Therefore, a treatment liquid obtained by mixing a dry-cleaning detergent, water and a petroleum-based solvent, that is, a detergent called a so-called sasara solution, is prepared, and textiles such as clothes are stained by using the detergent by brushing or the like. Dirt is removed. Among them, JP-A-57-5-5 is a surfactant having excellent cleaning performance and hydration performance.
The dialkyl sulfosuccinic surfactants described in 3600 are known. Although the cause is not clear, dry cleaning detergents containing these dialkylsulfosuccinic acid-based surfactants and nonionic surfactants cause cloudiness or precipitates in the solution, especially during low-temperature storage. However, it has been difficult to use it for sasara liquid prepared by mixing water and a petroleum solvent. Therefore, as described in JP-A-62-288698, a conventional dry-cleaning detergent uses a dialkylsulfosuccinic acid-based surfactant and a polyoxyethylene alkylphenyl ether-type nonionic surfactant to remove water. Although it was possible to obtain a uniform and stable product even if a sasara liquid mixed with petroleum solvents was prepared, recently, non-ionic surfactants of the polyoxyethylene alkylphenol ether type have a risk of affecting environmental hormones. It is regarded as a problematic substance, and its use must be refrained in view of its effects on actual workers.
