Definitions
- the invention relates to powdered, pourable and free-flowing surfactant mixtures which contain alkyl sulfate, alkyl glycoside and inorganic carrier material, a process for their preparation and their use as premixes (compounds) for the production of particulate detergents and cleaning agents.

- Preferred surfactants used are anionic surfactants, especially those of the alkylbenzenesulfonate type, and nonionic surfactants, especially ethoxylated fatty alcohols.
- the water is preferably removed from the slurry by spray drying.
- Modern powder detergents or cleaning agents generally consist of several separately manufactured powder components which, depending on the nature of their ingredients, require different manufacturing processes.
- a preferred manufacturing process for the surface-active substance-containing component of such agents is because of its relative ease. the spray drying of an aqueous solution or slurry of the ingredients.
- such a process requires a thermal load capacity of the surface-active ingredients, which is ensured when anion surfactants customary to date are used, in particular from the class of alkylbenzenesulfonates.
- alkylbenzenesulfonate in washing and cleaning agents has recently been increasingly questioned because of the petroleum base of this surfactant.
- sulfation products of compounds accessible from renewable raw materials, in particular fatty alcohols come into consideration as environmentally compatible anionic surfactants with comparable good cleaning properties.
- aqueous slurries containing alkylbenzenesulfonate can be spray-dried without problems at the temperatures customary in such processes, normally about 250 ° C. to 350 ° C., it has now been found that, under these conditions, aqueous slurries containing the same amount of Contain alkyl sulfates, there is a risk of spontaneous combustion.
- nonionic surfactants include, in particular, alkyl glycosides with long-chain alkyl groups, which have recently been used with preference because of their advantageous properties.
- alkyl glycosides are normally obtained as highly viscous pastes, which means that their use in relatively high concentrations in aqueous slurries intended for spray drying did not appear promising due to the high mechanical stress in such a process.
