Abstract
Aqueous emulsions of amine functionalized organopolysiloxane particles useful in personal care applications and methods for making are described. Useful compositions can be made by contacting at elevated temperatures, aqueous emulsions of organopolysiloxane particles having a volume average particle diameter in a range between about 300 nanometers and about 1 micron with an amine functionalized organosilicon source material, such as an aminoorganopolyalkoxysilane or an aminoorganopoly(diorganosiloxane) fluid.
