Abstract: Aqueous emulsions contain (A) oxamidoester-functionalized organopolysiloxanes having units of the formula R1a(OR2)bZcSiO(4−a−b−c)/2  (I) where Z is a group of the formula —Y—NRX—CO—CO—O—R3  (II), with the proviso that the sum a+b+c is ≤3 and each molecule contains at least one radical Z. (B) emulsifiers and (C) water.
