  • Hydrophilic softhand agency for fibrous materials and use thereof
    Patent number: 5019281
    Abstract: The present invention relates to hydrophilic softhand agents for fibrous materials which besides customary emulsifiers, known ingredients and water contain a water-soluble ammonium salt with at least one fatty acid radical as component (1), at least one quaternary ammonium compound other than component (1) with at least one long-chain alkyl radical as component (2) and conventionally dispersed polyethylene wax as component (3). The use of these softhand agents for treating fibrous materials, in particular textiles, is also described.The present hydrophilic softhand agents are notable for combining good to very good hydrophilicity and a pleasantly soft, fleecy/full softhand with virtually unimpaired whiteness of the treated materials and extremely good storage and temperature stability.
