A process as claimed in any of the preceding claims, wherein said active component is an insect and/or moth repellant, preferably selected from citronellal, citral, N, N diethyl meta toluamide, Rotundial, 8-acetoxycarvotanacenone, and mixtures thereof. 6. A process as claimed in any of the preceding claims, wherein said active component is an antimicrobial, preferably selected from Glutaraldehyde, Cinnamaldehyde, and mixtures thereof. 7. A process as claimed in any of the preceding claims, wherein the active is a perfume preferably selected from alpha-damascone, delta damascone, Carvone, Gamma-Methyl- lonone; Damascenone, hedione, 2.4-dimethyl-3-cyclohexen-l-carboxaldehydel, Florhydral, Lilial, heliotropine, trans-2-nonenal, citral, and mixtures thereof. 8. A process as claimed in any of the preceding claims, wherein the amount of amine reaction product ranges from 5 to 30%, by weight of the processes amine reaction product. 9. A process as claimed in any of the preceding claims, wherein the carrier has a melting point between 45°C and 85°C. 10. A process as Claimed in any of the preceding claims, wherein said carrier is selected from organic polymeric compounds, waxes, paraffins, oils, glycerides, monoglycerides, diglycerides, triglycerides, anionic surfactants; nonionic surfactants, cationic surfactants, zwitterionic surfactants, and mixtures thereof, preferably selected from organic polymeric compound, nonionic surfactants, and mixtures thereof, more preferably nonionic surfactants selected from nonionic ethoxylated alcohols. 11. A process as claimed in any of the preceding claims, wherein the amount of carrier material range from 15 to 80% and preferably from 25 to 75%, by weight of the produced particles of the processed amine reaction product. 12. A process as claimed in any of the preceding claims, wherein the coating is made of water-soluble agglomerating agent. 13. A process as claimed in any claim 12, wherein the water-soluble agglomerating agent is selected from water soluble organic polymeric compounds, water soluble monomeric polycarboxylates, or their acid forms, home or copolymeric polycarboxylic acids or their salts in which the polycarboxylic acid comprises at least two carboxylic radicals separated from each other by not more that two carbon atoms, carbonates, bicarbonates, borates, phosphates, sulfate salts, inorganic perhydrate salts, silicates, starch, cyclodextrin, and mixtures thereof, preferably selected from starch, carbonate, cyclodextrin, and mixtures thereof. 14. A process as claimed in any of the preceding claims, wherein the amount of amine reaction product ranges from 1 to 75%, preferably 5 to 30% by weight of the coated particle. 15. A processed amine reaction product as obtainable by the process as claimed in claims 1-14. 16.
