Claim:
1. A method for producing selectively primary amino group-carrying siloxanes of general formula 1 or a quaternary ammonium derivative thereof, wherein where M=(R M′=(R M″=(R M′″=(R D=(R D′=(R D″=(R D′=(R T=(R Q=(SiO a is in a range of from 0 to 32; a1 is in a range of from 0 to 10; a2 is in a range of from 0 to 32; a3 is in a range of from 0 to 10; b is in a range of from 0 to 600; b1 is in a range of from 0.1 to 50; b2 is in a range of from 0.1 to 20; b3 is in a range of from 0 to 50; c is in a range of from 0 to 20; and d is in a range of from 0 to 20; wherein: if a1=2, at least one of b1, b2, b3, a2 and a3 is not 0 and at least two of the factors a2, a3, b1, b2 and b3 are not 0; R R R x is in a range of from 0 to 100, x′ is in a range of from 0 to 1, y is in a range of from 0 to 100, R′ is each independently a linear or substituted alkyl or aryl group having 1 to 12 carbon atoms, where, within at least one of a radical R R″ is each independently a hydrogen radical or an alkyl group having 1 to 4 carbon atoms, or a group —C(O)—R′″ where R′″=an alkyl radical, a group —CH R R R (a) laterally epoxy-modified siloxane of formula 3 where: M=(R M′″″=(R M″=(R M′″=(R D=(R D′″″=(R D″=(R D′″=(R T=(R Q=(SiO where a, a1, a2, a3, b, b1, b2, b3, c, d, R R are reacted (b) with ammonia or instead of ammonia, with an ammonium compound which is capable of producing ammonia, (c) in the presence of a ring-opening catalyst or at a pressure 4 bar and above (d) at a minimum temperature of 60° C. to 150° C.
