Abstract
Abstract There are provided substantially trialkylsiloxy terminated polysiloxanes having at least one amino or substituted amino group linked to at least one trifunctional siloxy unit of said polysiloxane through an alkylene or arylene bridge. Emulsions of such polysiloxanes as well as methods for treating fabrics therewith are also provided.
