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.
Claims2
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—(CH2)m(CF2)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 CH3, CH3O or CF3, 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:
- C6H5—CH2O—(CH2CH2O)m—R1 [Formula 2]
- R2—O—(CH2CH2O)m—R1 [Formula 3]
- R1—R3—R2 [Formula 4]
- where m is an integer of 1 to 5, R1 is H or alkyl having 1 to 4 carbon atoms, R2 is alkyl having 1 to 8 carbon atoms, and R3 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.
