This invention relates to a process for preparing a sulfophenethylsiloxane having either of the following formulae: <IMAGE> (I) <IMAGE> (II) comprising: (a) adding in essentially equimolar ratio chlorosulfonic acid and a chorosilane having either of the following formulae: <IMAGE> (III) <IMAGE> (IV) wherein R of formulae I, II, III, and IV is individually hydrogen, halogen, or an alkyl radical having 1 to 4 carbon atoms; R1 is an alkylene radical having 2 to 5 carbon atoms; R2 is R of <IMAGE> with the proviso that at least one R2 be <IMAGE> R3 is R or -R1SiCl3 with the proviso that at least one R3 be -R1SiCl3 and n is at least 1, m is 1 or 2; continuously through a mixing nozzle in form of small droplets into a continuous stream of air with a temperature of from about 80 DEG C. to about 150 DEG C. in a reaction vessel to form a solid intermediate and (b) hydrolyzing said intermediate with water.
