Detergent mixtures and detergents or cleaning formulations with improved dissolving properties

The process of producing a high density washing-active extrudate comprising extruding under pressure a substantially water-free solid detergent mixture containing a plasticizer or lubricant wherein said detergent mixture comprises

• a) alkyl or alkenyl sulfates corresponding to formula (I):
• R.sub.1 OSO.sub.3 X (I)
• in which R.sub.1 is a linear or branched aliphatic hydrocarbon radical containing 16 to 18 carbon atoms and X is an alkali metal or alkaline earth metal, ammonium, alkylammonium, alkanolammonium or glucammonium,
• b) alkyl or alkenyl sulfates corresponding to formula (II):
• R.sub.2 OSO.sub.3 X (II)
• in which R.sub.2 is a linear or branched aliphatic hydrocarbon radical containing 12 to 14 carbon atoms and X is as defined above, and
• c) a hydrophobic structure breaker corresponding formula (III):
• R.sub.4 O(CH.sub.2 CH.sub.2 O).sub.n H (III)
• in which R4 is a linear or branched alkyl or alkenyl radical containing 12 to 18 carbon atoms and n is 0 or a number of 1 to 5, with the proviso that said components a) and b) are present in a ratio by weight of 90:10 to 70:30, to form strands of said extrudate, and cutting said strands of said extrudate to a desired granule size with a cutting unit.
