1. An additive delivery particle comprising:(i) a central core particle, said core particle comprising a porous carrier material and an additive contained in the pores of said porous carrier material; said additive comprising a perfume;(ii) an intermediate coating material coated on said central core particle, said intermediate coating material comprising a hydrophobic oil material; and(iii) an external encapsulating material coated on said intermediate coating material, said external encapsulating material providing said additive delivery particle with a substantially non-tacky surface; said external coating material comprising one or more at least partially wash soluble or dispersible compounds selected from the group consisting of carbohydrates, cellulose and cellulose derivatives, natural and synthetic gums, silicates, borates, phosphates, chitin and chitosan, water soluble polymers, fatty compounds, and mixtures thereof. 2. An additive delivery particle according to claim 1, wherein said intermediate hydrophobic oil coating material has a ClogP lower than the ClogP of the additive material contained in the porous carrier material. 3. An additive delivery particle according to claim 2 comprising:(i) from about 5% to about 50% of said central core particle, said core particle comprising by weight of the core particle, from about 60% to about 99% porous carrier material and from about 1% to about 40% additive material;(ii) from about 1% to about 40% said intermediate hydrophobic coating material; and(iii) from about 10% to about 94% said external encapsulating material. 4. An additive delivery particle according to claim 3 wherein said porous carrier material is a zeolite selected from the group consisting of Zeolite X, Zeolite Y, and mixtures thereof. 5. An additive delivery particle according to claim 3 wherein said additive loaded into said carrier is a perfume material. 6. An additive delivery particle according to claim 3 wherein said intermediate hydrophobic coating material is a perfume oil. 7. An additive delivery particle according to claim 3 wherein said external coating material is a carbohydrate selected from starch, modified starch or starch hydrolysate. 8. An additive delivery particle according to claim 3 comprising:(i) from about 5% to about 50% of said central core particle, said core particle comprising by weight of the core particle from about 60% to about 99% zeolite as porous carrier material and from about 1% to about 40% perfume material;(ii) from about 1% to about 40% perfume oil as intermediate coating material; and(iii) from about 10% to about 94% starch or modified starch as external encapsulating material. 9. An additive delivery particle according to claim 8 wherein said perfume material loaded into said zeolite carrier has a weighted average ClogP value between about 1.0 and about 16.0. 10. An additive delivery particle according to claim 8 wherein said perfume material loaded into said zeolite carrier comprises a high impact perfume characterized by having:(1) a standard B.P. of about 275° C. or lower at 760 mm Hg, and;(2) a ClogP, or an experimental logP, of about 2 or higher, and;(3) an ODT of less than or equal to 50 ppb and greater than 10 ppb. 11. An additive delivery particle according to claim 8 wherein said perfume oil used as intermediate coating material comprises a high impact perfume characterized by having:(1) a standard B.P. of about 275° C. or lower at 760 mm Hg, and;(2) a ClogP, or an experimental logP, of about 2 or higher, and;(3) an ODT of less than or equal to 50 ppb and greater than 10 ppb. 12. An additive delivery particle according to claim 8 comprising:(i) from about 10% to about 40% of said central core particle;(ii) from about 10% to about 30% perfume oil as intermediate coating material; and(iii) from about 30% to about 80% starch or modified starch as external encapsulating material. 13. A laundry or cleaning detergent composition comprising:a) from about 0.001% to about 50% by weight of the composition of an additive delivery particle comprising:(i) a central core particle, said core particle comprising a porous carrier material and an additive contained in the pores of said porous carrier material; said additive comprising a perfume;(ii) an intermediate coating material coated on said central core particle, said intermediate coating material comprising a hydrophobic oil material; and(iii) an external encapsulating material coated on said intermediate coating material, said external encapsulating material providing said laundry additive delivery particle with a substantially non-tacky surface; said external coating material comprising one or more at least partially wash soluble or dispersible compounds selected from the group consisting of carbohydrates, cellulose and cellulose derivatives, natural and synthetic gums, silicates, borates, phosphates, chitin and chitosan, water soluble polymers, fatty compounds, and mixtures thereof; andb) from about 50% to about 99.999% by weight of the composition of laundry ingredients selected from the group consisting of detersive surfactants, builders, bleaching agents, enzymes, soil release polymers, dye transfer inhibitors, fillers and mixtures thereof.
