  • 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. Due to the low solubility of carboxymethylcellulose in liquid detergents or cleaners, turbidity occurs when incorporating carboxymethylcellulose into liquid detergents or cleaners. This leads to an aesthetically less appealing product.
  • washing or cleaning agents In order to increase or prolong the scent impression on the washing or cleaning agents treated therewith surfaces, such as textiles, for example, washing or cleaning agents contain perfume capsules. In order to achieve a homogeneous and stable distribution of the perfume capsules and thus to arrive at an aesthetically pleasing product, the detergents or cleaners contain thickeners and / or dispersants.
