Abstract

The present application relates to organosilicones and compositions such as consumer products comprising such organosilicones, as well as processes for making and using such organosilicones and such compositions. Such compositions comprising such organosilicones are easier to formulate, and provide more economical and superior care benefits when compared to current silicone containing compositions.
