A fabric treatment composition comprising an aqueous base, one or more, fabric-softening materials and an emulsion component, said composition having a structure of lamellar droplets of the fabric-softening material in combination with an emulsion, said composition also comprising a deflocculating polymer comprising a hydrophilic backbone and one or more hydrophobic side chains. The deflocculating polymer allows the incorporation of greater amounts of softening materials and/or emulsion components that would otherwise be compatible with the need for a stable, easily dispersible product of acceptable viscosity.

Why it's free to use
- Filed May 21, 1991 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 21, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 21, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
