Method for producing acyl amino acids

Surfactant combinations containing C alkyl sulfates wherein less than 10% by weight of the C alkyl sulfates, based on the C alkyl sulfates, have carbon chains with fewer than 14 carbon atoms and C alkyl benzenesulfonates in a weight ratio of 1:10 to 10:1. The combinations are useful in powder and granular as well as liquid washing and cleaning detergents.

Surfactant combination containing alkylsulfate and alkylbenzenesulfonate anionic surfactants

A process for making substantially odorless granules of alkyl sulfates corresponding to formula (I): R-O-SO X (I) wherein R is an alkyl group containing from 6 to 18 carbon atoms, and X is selected from the group consisting of an alkali metal, an alkaline earth metal, ammonium, an alkyl ammonium, and alkanolammonium, and a glucammonium ion, the process involving: (a) providing a water-containing paste of alkyl sulfates having a content of unsulfonated components of greater than 0.3% by weight; and (b) simultaneously granulating and drying, in a fluidized bed, the water-containing paste of alkyl sulfates to form substantially odorless granules of alkyl sulfates, and wherein the substantially odorles granules thus formed have less than 0.2% by weight, based on the weight of active substance, of unsulfonated components present therein.

Process of making alkyl sulfate granulates

A process for making detergent granules having a bulk density above 500 g/l involving: (a) providing a fluidized bed; (b) providing an apertured inflow base located below the fluidized bed for introducing fluidization gas into the fluidized bed; (c) providing a grid interposed between the fluidized bed and the apertured inflow base, the grid having a mesh size of less than 600 &mgr;m; (d) providing a surfactant preparation in liquid to paste form; and (e) introducing the surfactant preparation into the fluidized bed to form the detergent granules.

Method for producing tenside granulates with a higher bulk density

A water-free surfactant composition is presented having (a) a fatty alcohol sulfate corresponding to the formula R,O&mdash;SO,X where R,is a linear alkyl chain containing 16 or 18 carbon atoms and X is an alkali metal, alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium and (b) an alcohol sulfate corresponding to the formula R,O&mdash;SO,X where R,is an alkyl chain containing 12 to 15 carbon atoms consisting of a minimum 20 percent by weight branched alkyl chains and a maximum 80 percent by weight unbranched alkyl chains, and X is an alkali metal or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium. The surfactant composition has a reduced potential for irritation and good flowability and solubility in cold water. The surfactant composition is useful in laundry detergents, dishwashing detergents and other cleaners.
