Definitions

  • the invention relates to a liquid surfactant-containing detergent which contains a specific cellulose derivative as graying-inhibiting active ingredient.
  • Graying inhibitors have the task of keeping the fabric removed from the fiber during washing of the fiber suspended in the liquor and thus prevent the re-raising of the dirt on the textile.
  • Water-soluble colloids of mostly organic nature are suitable for this purpose, for example glue, gelatine, salts of ether sulfonic acids or cellulose or salts of acidic sulfuric acid esters of cellulose or starch.

From this, the degree of polymerization and, taking into account the degrees of substitution, the corresponding molecular weight can be calculated.
