Organopolysiloxane-containing composition for treating substrates

A composition obtained by mixing components comprising

• (A) 100 parts by weight of an organopolysiloxane component having the formula R.sub.a X.sub.b Y.sub.c Z.sub.d SiO.sub.(4-a-b-c-d)/2 wherein R denotes a monovalent hydrocarbon group;
• X denotes a group having the formula --R.sup.1 (NHCH.sub.2 CH.sub.2).sub.e NR.sub.2.sup.2, wherein R.sup.1 denotes a divalent hydrocarbon group, R.sup.2 denotes a hydrogen atom or a monovalent hydrocarbon group and e is an integer from 0 to 3;
• Y denotes a group having the formula --R.sup.3 OH or --R.sub.f.sup.3 O(C.sub.m H.sub.2m O).sub.g R.sup.4 wherein R.sup.3 denotes a divalent hydrocarbon group, R.sup.4 denotes a hydrogen atom or a terminating group, f is 0 or 1, g has a value of from 1 to 100 and m is an integer from 1 to 5;
• Z denotes a hydroxyl group or an alkoxy group;
• a has a value of from 1.90 to 2.20;
• b has a value of from 0.0001 to 0.2;
• c has a value of from 0.0001 to 0.2;
• d has a value of from 0 to 0.2 and the sum of a+b+c+d has a value of from about 1.90 to 2.20,
• (B) 0 to 100 parts by weight of a nonionic or a cationic surfactant,
• (C) 0.1 to 50 parts by weight of an organic ester of titanic, zirconic or germanic acid,
• (D) an amount of acid sufficient to provide a pH of from 2.5 to 7.0 for the composition, and
• (E) an amount of water effective to emulsify or dissolve component (A).
