Definitions

  • the invention relates to a liquid washing or cleaning agent containing surfactant (s) and a cellulose or a cellulose derivative.
  • the invention also relates to processes for the preparation of the washing or cleaning agent.
  • detergents or cleaners To increase the washing or cleaning performance of detergents or cleaners they often contain one or more additives.
  • detergents in order to prevent re-release of previously released soil in finer distribution (redeposition), detergents contain so-called graying inhibitors, such as carboxymethylcellulose.
  • EP 054325 A1 a detergent with carboxymethylcellulose as a grayness inhibitor.
  • GB 729531 A Liquid detergents with acidic cellulose sulfates are proposed.
  • DE 10 2007 021 793 A1 relates to detergents comprising surfactant, graying-inhibiting polysaccharide having a particle size of less than 100 nm and other conventional ingredients.
  • liquid detergents or cleaners have increasingly been offered in transparent bottles. Due to the low solubility of carboxymethylcellulose in liquid detergents or cleaners, incorporation of carboxymethylcellulose into liquid detergents or cleaners results in turbidity: this leads to an aesthetically less appealing product, especially if it is offered in a transparent bottle.
  • Another problem is that stable dispersions of cellulose or cellulose derivatives in the matrix of a detergent or cleaning agent are very difficult to obtain.
  • the incorporability into a liquid matrix of a washing or cleaning agent can be improved by an acid treatment of cellulose or a cellulose derivative without losing the graying-inhibiting property of the cellulose or of the cellulose derivative.
  • the improved incorporability of aesthetically pleasing liquid detergents or cleaners are obtained with graying-inhibiting property.
  • the agent is an acid-treated cellulose derivative selected from the group consisting of acid-treated carboxymethylcellulose (CMC), an acid-treated cellulose acid sulfonic acid ester salt, acid-treated methylcellulose, acid-treated ethylcellulose, acid-treated hydroxyethylcellulose, acid-treated hydroxypropylcellulose, acid-treated hydroxypropylmethylcellulose, acid-treated methylhydroxyethylcellulose, acid-treated methylcarboxymethylcellulose, acid-treated ethylhydroxyethylcellulose and a mixture of these acid-treated cellulose derivatives.

  • cellulose or cellulose derivative have proven to be particularly advantageous. At a level of 0.01% by weight, no graying-inhibiting effect can be observed, and at amounts greater than 8% by weight, no further increase in the graying-inhibiting effect of the liquid detergent or cleaning agent can be observed.
