Definitions
- cleaning compositions such as hand dishwashing compositions are those that they should have a certain consistency or viscosity.
- the desired viscosity expected by the consumer, should not be too thin.
- the consumer desires viscous formulations allowing a controlled handling (providing good pourability and ease of dissolution in water). Also, the consumer associates viscous cleaning compositions with good performance and quality as well as with high levels of active ingredients.
- high viscous cleaning compositions are achieved by incorporating gums, polymeric thickeners and/or high levels of salts and/or active matter of surfactants into the cleaning compositions.
- This technique has at least one drawback that it negatively affects the formula costs while providing no benefit (apart from thickening).
