A polyorganosiloxane compound comprising:
- a) at least one polyorganosiloxane group,
- b) at least one quaternary ammonium group,
- c) at least one terminal ester group, wherein the polyorganosiloxane compound is a linear copolymer compound which comprises the above functional groups (a) and (b), with at least part of the terminal groups being terminal ester groups (c) that result from the use of monofunctional organic acids as chain stoppers.
A polyorganosiloxane compound consisting essentially of:
- a) at least one polyorganosiloxane group,
- b) at least one quaternary ammonium group, and
- c) at least one terminal ester group, wherein the polyorganosiloxane compound is a linear copolymer compound which comprises the above functional groups (a) and (b), with at least part of the terminal groups being terminal ester groups (c) that result from the use of monofunctional organic acids as chain stoppers.
