Definitions

  • the present invention relates to detergent compositions which clean well and at the same time act as textile softeners.
  • European Patent Application 0 026 528 describes the use of water-insoluble long chain tertiary amines in conjunction with a water-soluble cationic quarternary ammonium compound and/or a water-soluble aliphatic amine, optionally with clays, in alkaline detergent compositions to provide fabric softening properties.
  • EP-A 0 120 528 teaches alkaline softening detergent compositions comprising a synergistic mixture of a water-insoluble C10-C26 tertiary amine and cellulase.

  • the present invention also addresses standing prior-art issues by using a cellulase enzyme at a pH range where its activity is optimum, and by the surprising discovery that water-insoluble long chain amines such as described in EPA 0 026 528 or EPA 0 120 528, give softeness negatives in presence of cellulase, upon cumulative washes, under the mild alkaline conditions of the invention.
  • the present invention relates to detergent compositions for the cleaning and softening of fabrics, comprising a surface-active agent, of which at least 50% by weight is a non-soap anionic surface active agent, and a cellulase ;
