Description

 Hand dishwashing detergent with native surfactant combination

The subject of this application is the use of a surfactant combination of a Fettal koholether- sulfate and a betaine in a concentrated hand dishwashing detergent, which further contains at least one viscosity-reducing ingredient.

Commercially available hand dishwashing detergents usually contain combinations of several surfactants in order to meet the requirements for the agent with regard to cleaning performance and foaming. The surfactants are usually both those which are obtained from renewable raw materials, as well as petrochemical surfactants. The latter have many desirable properties. For example, secondary alkanesulfonates are characterized by good solubility and foaming. However, it is considered disadvantageous by some consumers that, in contrast to those obtained from renewable raw materials, these surfactants are not anaerobically degradable and can thus lead to a greater water pollution.

It was therefore desirable to formulate a hand dishwashing detergent which dispenses substantially or wholly with the use of such non-anaerobically degradable surfactants. A combination of fatty alcohol ether sulfate and betaine would fulfill this requirement as they can be obtained from renewable raw materials.

In the meantime, concentrates with a high surfactant content have proven to be particularly advantageous in the formulation of hand dishwashing detergents. However, such concentrates often have a very high viscosity. If a concentrate is formulated with a combination of fatty alcohol ether sulfate and betaine, the result is first a highly viscous system, which also has a poor cold behavior.

An object of this invention was therefore to provide a hand dishwashing detergent with good cleaning performance based on renewable raw materials, which has a good cold behavior and no viscosity problems.

It has now been found that the use of a surfactant combination of a fatty alcohol ether sulfate and a betaine in a concentrated hand dishwashing detergent, which further contains at least one viscosity-reducing ingredient, leads to largely anaerobically degradable, low-temperature pourable agents. The subject of this invention is therefore the use of a surfactant combination of a fatty alcohol ether sulfate and a betaine in a concentrated hand dishwashing detergent, the agent further containing at least one viscosity reducing ingredient. This is preferably at least one organic solvent and / or at least one hydrotrope and / or at least one water-soluble salt.

In the context of the present invention are fatty acids or fatty alcohols or their derivatives - unless otherwise stated - representative of branched or unbranched carboxylic acids or alcohols or their derivatives having preferably 6 to 22 carbon atoms. The former are particularly preferred because of their vegetable base as based on renewable raw materials for ecological reasons. Whenever in the following alkaline earth metals are mentioned as counterions for monovalent anions, this means that the alkaline earth metal, of course, only in the half - for charge equalization sufficient - amount of substance as the anion is present.

Chemical compounds carry an INCI name in English, plant ingredients are listed only after Linne in Latin. So-called trivial names such as "water", "honey" or "sea salt" are also given in Latin.
