Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cleaning composition for dry cleaning and a cleaning method. More specifically, the present invention relates to a dry-cleaning detergent composition and a cleaning method which can provide excellent cleaning properties and anti-redeposition properties, and can provide an object to be washed with excellent smoothness and flexibility. .

2. Description of the Related Art In washing clothes, etc., in addition to wet cleaning in which water is used for neutral washing and laundry in which washing is carried out using alkaline, petroleum solvents, perchlorethylene, CFC-113, 1,1 are used as solvents. , 1-Trichloroethane, dry cleaning using alternative fluorocarbons such as HCFC-225 and HCFC-141b, and hydrofluoroethers such as methyl perfluorobutyl ether and ethyl perfluorobutyl ether. However, these solvents used for dry cleaning have a low boiling point, so that drying is easy and quick, and mechanical damage to clothes is relatively small. However, 1,1,1-trichloroethane and HCFC-113 were used at the end of 1995. In developed countries, production has been suspended, and perchlorethylene, a chlorinated solvent, is subject to strict emission regulations, and petroleum solvents belong to the 4th petroleum class under the Fire Services Act, are dangerous substances and have a high boiling point, so they easily remain. May cause chemical burns due to solvent. In addition, HCFC-225 and HCFC-1
Since 41b and the like may destroy the ozone layer, the usable period is limited, and a hydrofluoroether solvent having a zero ozone depletion potential and a small global warming potential has been proposed, but is expensive. The fact is that it has not spread.

[0003] Conventional cleaning compositions used for dry cleaning generally contain a cationic surfactant, an anionic surfactant, and a nonionic surfactant as main components. It has properties such as water hydration, flexibility and antistatic properties. In addition, most of these surfactants are based on hydrocarbons as lipophilic groups, and the above-mentioned solvents used for dry cleaning generally have a high dissolving power of organic compounds. There was no need to use.

[0004] In recent years, there has been virtually no emission control, and there is a demand for a solvent for dry cleaning which is less likely to cause chemical burns even when it comes into contact with the skin. Silicone solvents with a high level of attention have attracted attention and are used in some cleaning facilities. However, silicone-based solvents have poor dissolving power of organic compounds, and the above-mentioned hydrocarbon-based surfactants, which have been mainly used as detergent compositions, are hardly dissolved and cannot be used, Particular surfactants that are partially dissolved in a silicone-based solvent cannot exhibit basic performance such as detergency and recontamination-preventive power that should be provided as a detergent composition.

[0005] Therefore, a dry cleaning detergent composition which is excellent in detergency and anti-redeposition properties, can impart smoothness and flexibility to an object to be washed, and can be used by being added to a silicone solvent. Things are desired.

[0006]
