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.
Claims8
An aqueous emulsion of amine functionalized organopolysiloxane particles having a volume average particle diameter of at least about 300 nanometers;
- wherein the amine functionalized organopolysiloxane particles are derived from the reaction between organopolysiloxane particles having a volume average particle diameter of at least about 300 nanometers and an aminoorganopolysiloxane;
- and
- wherein the volume average particle diameter of the amine functionalized organopolysiloxane particles is substantially maintained upon functionalization.
A substantially stable aqueous emulsion having solids in a range of between about 5% by weight and about 60% by weight, comprising dispersed amine functionalized organopolysiloxane particles that have a volume average particle diameter of at least about 300 nanometers, said particles consisting essentially of diorganosiloxy units in the range between about 50 mole % and about 99 mole % chemically combined with (aminoorgano)organosiloxy units in a range between about 50 mole % and about 1 mole %;
- wherein the amine functionalized organopolysiloxane particles are derived from the reaction between organopolysiloxane particles having a volume average particle diameter of at least about 300 nanometers and an aminoorganopolysiloxane;
- and
- wherein the volume average particle diameter of the amine functionalized organopolysiloxane particles is substantially maintained upon functionalization.
