Improvements relating to furniture polish

Abstract: A furniture polish includes micro-capsules holding polish fragrance and at least a proportion of the active polishing ingredients, the micro-capsules being produced by a coacervation, three phase method such that they have varying wall thicknesses.

Description: This invention relates to a furniture polish. According to one aspect of the invention, there is provided a furniture polish incorporating fragrance, wherein the fragrance is at least in part micro-encapsulated in a multitude of naturally self-adhesive micro-capsules of varying wall thickness. The micro-capsules are preferably produced by the known coacervation, three phase method. Preferably, the entire fragrance in the polish is held in the micro-capsules, and preferably at least a proportion of the one or more active polishing ingredients of the polish are also micro-encapsulated, conveniently in the same micro-capsules as the fragrance. The polish is preferably accommodated in an aerosol, trigger spray or pump spray format. According to another aspect of the invention, there is provided a furniture polish incorporating fragrance, wherein at least a proportion of the fragrance and at least a proportion of the one or more active polishing ingredients are micro-encapsulated in a multitude of naturally self-adhesive micro-capsules of such varying wall thicknesses that, on first application of the polish with a duster, only some of the micro-capsules are fractured and the rest become attached to the fibres of the duster, whereby on a subsequent further use of the duster without application of further polish, at least some of the micro-capsules attached to the duster are caused to fracture to release further fragrance and active polishing ingredient. When in this further aspect of the invention the polish is applied as a spray, thinner walled capsules will fracture to release fragrance and polishing ingredient due to passage through the spray nozzle. The invention is further described with reference to the following example. Micro-capsules containing a polish fragrance and at least a proportion of the active polishing ingredients of the polish system are formed by the known coacervation, three phase method. This method of production is controlled so that the micro-capsules have an average diameter in the range 3 to 30 microns, preferably 4 to 16 microns and more preferably about 5 microns, and are of varying wall thicknesses. The micro-capsules are incorporated into the polish base, which may already include a proportion of the active polishing ingredients, to form a generally uniform suspension therein. The polish system is then filled into a spray container. When the polish is used, only some of the micro-capsules fracture on passage through the spray nozzle, to enable polishing with a duster accompanied by release of fragrance. Thicker walled capsules become entrapped on the fibre duster where they will harden and tend to become brittle over time, so that when the duster is next used, without further application of polish, further fragrance and active polishing ingredient are released due to friction generated by the polishing action with the duster.

Claims: A furniture polish incorporating fragrance, wherein the fragrance is at least in part micro-encapsulated in a multitude of naturally self-adhesive micro-capsules of varying wall thickness. A polish according to claim 1, wherein the micro-capsules are produced by a coacervation, three phase method. A polish according to claim 1, wherein the entire fragrance is held in the micro-capsules. A polish according to claim 1, wherein a proportion of at least one active polishing ingredient is also micro-encapsulated. A polish according to claim 4, wherein the at least one polishing ingredient is held in the same micro-capsules as the fragrance. A polish according to claim 1, accommodated in an aerosol, trigger spray or pump spray format. A furniture polish incorporating fragrance, wherein at least a proportion of the fragrance and at least a proportion of the one or more active polishing ingredients are micro-encapsulated in a multitude of naturally self-adhesive micro-capsules of such varying wall thicknesses that, on first application of the polish with a duster, only some of the micro-capsules are fractured and the rest become attached to the fibres of the duster, whereby on a subsequent further use of the duster without application of further polish, at least some of the micro-capsules attached to the duster are caused to fracture to release further fragrance and active polishing ingredient. A polish according to claim 7, wherein the micro-capsules are produced by a coacervation, three phase method. A polish according to claim 7, wherein the entire fragrance is held in the micro-capsules. A polish according to claim 7, incorporated in a spray format whereby, when applied as a spray, thinner walled capsules will fracture to release fragrance and polishing ingredient due to passage through the spray nozzle.
