| 20080200362 | POWDER DETERGENT GRANULE CONTAINING ACIDIC WATER-SOLUBLE POLYMER AND MANUFACTURING METHOD THEREOF - The present invention relates to powder detergent granules that are substantially free of a water-insoluble component such as zeolite or silica, a method for manufacturing the powder detergent granules and a copolymer having various properties useful as a detergent component. The powder detergent granules of the present invention are substantially free of a water-insoluble component, and thus exhibit good solubility and washing performance (stain removal performance) in cold water, do not leave residue after laundry, and reduce the likelihood of a caking phenomenon during manufacture and storage. And, the powder detergent granules of the present invention are substantially free of zeolite or silica that absorbs a liquid component, but are capable of accommodating a considerable amount of liquid surfactant. Further, a copolymer comprising acrylic acid monomer unit and 2-acrylamido-2-methylpropane sulfonic acid monomer unit, an acidic water-soluble polymer of the present invention, is useful as a detergent component in various aspects. | 08-21-2008 |
| 20090181587 | FUNCTIONAL SHEET FOR DELIVERING LAUNDRY ACTIVES IN LOW-TEMPERATURE WATER - Disclosed are a functional sheet including a first substrate applied or impregnated with an active ingredient, which is to be used in low temperature water at 0° C. to 30° C., wherein the active ingredient is to be physically or chemically adsorbed on a second substrate in the low temperature water, and remain on the second substrate after removal of the low temperature water, as the first substrate, a substrate having a water contact angle of 90° or less is used so that 70% or more of the active ingredient applied or impregnated to the first substrate can be released in the low temperature water at 0° C. to 30° C. within 5 minutes; and another functional sheet including a first substrate applied or impregnated with an active ingredient, which is to be used in low temperature water at 0° C. to 30° C., wherein the active ingredient is to be physically or chemically adsorbed on a second substrate in the low temperature water, and remain on the second substrate after removal of the low temperature water, the functional sheet has light transmittance of 2 to 20%, so that 70% or more of the active ingredient applied or impregnated to the first substrate can be released in the low temperature water at 0° C. to 30° C. within 5 minutes. | 07-16-2009 |
| 20100113325 | COMPOSITION FOR TEXTILE SOFTENER HAVING LOW TEMPERATURE ACTIVITY AND TEXTILE SOFTENER SHEET COMPRISING THE SAME - The present invention relates to a composition for textile softener comprising a cationic surfactant, the ratio of which C7-C21 alkyl substituents analyzed by HLPC (high pressure liquid chromatography) or GC (gas chromatography) is 0.6 or more, as an effective ingredient, and a sheet for textile softener comprising the same. Since the present composition for textile softener has excellent dissolving and dispersing effect even in low temperature water, the sheet comprising this composition is used at a rinse time during washing procedures to represent excellent anti-static effect and textile softening effect to textiles and clothes. | 05-06-2010 |
