Abstract
The disclosure defines a series of novel quaternary silicone polymers useful in softening hair, and fiber and conditioning skin. The compounds are silicone polymers which contain a quaternary nitrogen pendant group. In one embodiment, the quaternary nitrogen group has an alkylamido function, in another embodiment it contains a imidazoline derived function. These compounds have a high degree of oxidative stability, even at elevated temperatures, are non volatile and unlike many other traditional fatty quaternary compounds are non yellowing when applied to textile substrates.
