Definitions

  • the invention relates to a homogeneous concentrated and aqueous liquid detergent, a process for its preparation and its use for the manual and machine washing of textiles.
  • Aqueous liquid detergents which contain a mixture of anionic and customary nonionic surfactants and in which the content of nonionic surfactants, based on the total liquid detergent, is 20% by weight and more, generally have inhomogeneities which cause phase separation of the liquid detergent , for example a separation into two clear liquid phases or the flocculation of a solid. This phase separation occurs either directly during manufacture, during storage for several weeks (storage instability) or when diluted with water. Another disadvantage is that these agents often have such high viscosities that they can no longer flow without the influence of external gravitational forces.
