Abstract

A detergent composition for dry cleaning is disclosed. The detergent composition for dry cleaning includes a) 5 to 10% by weight of a fluorinated (fluoro-based) solvent, b) 1 to 2% by weight of a cleaning booster, c) 5 to 10% by weight of an anti-shrinkage agent, d) 40 to 50% by weight of a water-soluble solvent, and e) 30 to 40% by weight of water.

First claim

The invention claimed is:

1. A detergent composition for dry cleaning comprising:
a) 5 to 10% by weight of a fluorinated (fluoro-based) solvent;
b) 1 to 2% by weight of a cleaning booster;
c) 5 to 10% by weight of an anti-shrinkage agent;
d) 40 to 50% by weight of a water-soluble solvent; and
e) 30 to 40% by weight of water, wherein the a) fluorinated solvent comprises at least one selected from the group consisting of the following Formula 1 and a combination thereof:
R—(CH 2 ) m (CF 2 ) n —R  [Formula 1]

where m is an integer of 0 to 4, n is an integer of 1 to 5, and R is H or F, or CH 3 , CH 3 O or CF 3 , wherein the b) cleaning booster comprises at least one selected from the group consisting of a compound represented by the following Formula 2, a compound represented by the following Formula 3 and a compound represented by the following Formula 4:
C 6 H 5 —CH 2 O—(CH 2 CH 2 O) m —R 1   [Formula 2]

R 2 —O—(CH 2 CH 2 O) m —R 1   [Formula 3]

R 1 —R 3 —R 2   [Formula 4]

where m is an integer of 1 to 5, R 1 is H or alkyl having 1 to 4 carbon atoms, R 2 is alkyl having 1 to 8 carbon atoms, and R 3 is alkyl or alkene group having 3 to 20 carbon atoms, and wherein the d) water-soluble solvent comprises at least one selected from the group consisting of ethanol (EtOH), n-propanol (NPA), isopropanol (IPA), n-butanol (NBA), n-pentanol (NPA), n-hexanol (NHA) and a combination thereof.

2. The detergent composition for dry cleaning according to claim 1 , wherein the c) anti-shrinkage agent comprises at least one selected from the group consisting of propylene glycol (PG), hexylene glycol (HG), ethylene glycol (EG), butylene glycol (BG), 3-methoxy-3-methyl-1-butanol (3-MMB) and a combination thereof.
