Abstract:
Aminofunctional silicone compositions are disclosed comprising: an organopolysiloxane having an average formula of (CH3)3SiO[(CH3)2SiO]x [(CH3)RNSiO]ySi(CH3)3 with less than 1 weight % of nitrogen in its formula, where RN is an aminofunctional group, x is ≥100, y is ≥1 with the proviso the sum of x+y is from 250 to 350; wherein the viscosity of the silicone composition ranges from 1000 to 2500 cP at 25° C. and is measured by a Brookfield RV DV viscometer equipped with Pro CP 52 spindle at 20 RPM; and the aminofunctional silicone composition contains less than 0.1 weight % of D4 and less than 0.1 weight % D5 cyclic siloxanes.
