Detergent composition for removing oil-based stains}

The present invention relates to a cleaning composition having excellent oil-based stain removal ability. More specifically, the present invention provides (a) 0.1 to 30% by weight of a nonionic surfactant; (b) 5 to 50% by weight of 3-methoxy-3-methyl-butanol; (c) 5 to 45% by weight of diethylene glycol-t-butyl ether; and (d) intermediate alkyl (C6-C12) ethoxylate ( (EO 2 mol)) 0.1-30% by weight as an essential ingredient, which is a cleaning composition containing oil-based contaminants such as paint, oil, grease, etc. and ink stains such as ballpoint pens. It relates to a cleaning composition that effectively removes , improves base odor, is convenient to use, and does not contain allergens.

In the process of repeatedly wearing and washing clothes throughout our lives, when certain oil-based stains become contaminated, it is often difficult to remove them through a general washing process. For example, if oil paints, marker pens, etc. used for drawing at kindergartens or academies get on clothes, they are not easily removed even if washed with regular detergent.

Several products such as oil cleaners that remove oil stains are known and sold, but most of them remove oil stains by dissolving them using petroleum-based solvents. When using a petroleum-based solvent, oil-based stains are removed relatively well, but you may be exposed to a strong odor or feel unpleasant during work. There is a risk of fire or explosion due to the flammability of the petroleum-based solvent itself, and non-flammable solvents have high vapor toxicity, making it difficult to maintain hygiene. It's harmful. Additionally, the possibility that some materials used in clothing may be deteriorated or damaged by petroleum-based solvents cannot be ruled out.

S. Seed. Johnson & Son discloses a pre-stain remover for laundry containing a polymeric associative thickener (Korean Patent Registration No. 10-0245319), which is said to be a composition that efficiently removes oil-based stains from clothes, etc. at home. However, this composition alone is evaluated as insufficient as an oil-based stain remover.

Illinois Tool Works, Inc. discloses a paint and stain remover in an abrasive applicator for use on hard surfaces (Korean Patent Registration No. 10-0312371). However, the formulation uses volatile solvents such as butyl cellosolve and ethyl acetate, which have a strong odor, and although it is effective in removing oil-based stains such as paint, it has a strong base odor, which irritates the worker's nose and causes discomfort during use. I do it.

P&G's laundry detergent composition containing a hydrophobic solvent and a hydrophilic solvent (Korean Patent Publication No. 10-2000-0048762) has improved stain removal ability on various stains, including bleaching stains, enzyme stains, and/or mud/clay stains. claims to provide. However, although the solvent content used in the composition is low and stains on solid surfaces may be well removed, it is evaluated to be insufficiently effective in partially removing oil-based stains on textile clothing.

Kim Yeon-i explains that the advertising sticker trace peeling remover (Korea Patent Registration No. 10-0729560) removes advertising sticker traces well. This technology is evaluated to be good at removing sticker stains by appropriately using oil-based solvents, but there are safety issues due to the excessive use of limonene, a known allergen, and it runs counter to the recent trend of avoiding the use of allergens.
