Siloxanes having terminal hydroxy groups, and which have a content of cyclic siloxanes of not more than 5% by weight, are stabilized by addition of ammonia in gaseous form or as a solution in a protic or aprotic solvent or in the form of an ammonia-releasing compound in amounts of at least 0.01 ppm by weight and not more than 100 ppm by weight, calculated as ammonia and based on the total weight of the siloxanes having terminal hydroxy groups. Ammonia in gaseous form is preferably used.
