Abstract: Process for the preparation of a cationic starch having a controlled viscosity, in which, in one process step, the starch is homogenised in the presence of 10 to 35 % by weight of water and preferably 0.01 to 2.00 % by weight of a finely divided silica and/or silicate (based in each case on the total amount of the mixture) with an alkaline oxide, hydroxide, silicate or aluminate or a mixture thereof, an alkylene epoxide and a peroxy compound or a mixture of at least two peroxy compounds, and is then boiled down at the desired time.
