Aminofunctional silicone emulsions are prepared by forming a mixture of A) 100 parts of a polydialkylsiloxane Having a viscosity of at least 50,000 mm/s at 23° C., and B) 0.1 to 100 parts of an aminofunctional organopolysiloxane, admixing C) 0.1 to 50 parts of a halide free quaternary ammonium surfactant containing at least 10 carbon atoms, and a sufficient amount of water to form an emulsion. 1. A process for preparing an aminofunctional silicone emulsion comprising: [{'sup': '2', 'A) 100 parts of a polydialkylsiloxane having a viscosity of at least 50,000 mm/s at 23° C., and'}, 'B) 0.1 to 100 parts of an aminofunctional organopolysiloxane,, 'I) forming a mixture of;'} C) 0.1 to 50 parts of a halide free quaternary ammonium surfactant containing at least 10 carbon atoms, and', 'a sufficient amount of water to form an emulsion,, 'II) admixing;'}III) optionally, further shear mixing the emulsion.2. The process of wherein the polydialkylsiloxane is a trimethylsiloxy terminated polydimethylsiloxane having a viscosity of at least 100 claim 1 ,000 mm/s at 23° C.4. The process of wherein R is methyl and the amino functional group is{'sub': 2', '3', '2', '2', '2', '2, '—CHCH(CH)CHNHCHCHNH.'}5. The process of wherein the halide free quaternary ammonium surfactant has the formula;{'br': None, 'sup': 5', '6', '+', '−, 'sub': a', '(4-a), 'RRNX, wherein'}a may be vary from 1 to 4,{'sup': '5', 'Ris an organic group containing at least 10 carbon atoms,'}{'sup': '6', 'Ris independently a hydrocarbon group containing 1 to 20 carbon atoms,'}X is a halide free counter ion.6. The process of where Ris lauryl claim 5 , cetyl claim 5 , coco claim 5 , stearyl claim 5 , tallow claim 5 , cocoyl claim 5 , lauroyl claim 5 , palmitoyl claim 5 , myristoyl or stearoyl.7. The process of where Ris methyl or ethyl.8. The process of where X is methosulfate claim 6 , etho-sulfate claim 6 , acetate claim 6 , tosylate claim 6 , phosphate claim 6 , or nitrate.9. The process of wherein step II) further ...
