WE CLAIM:
1. A process for making particles of amine reaction product of a compound containing a
primary and/or secondary amine functional group an active component containing active
ketone or aldehyde of the kind hereinbefore described and which comprises the step of:
a) providing an amine reaction product comprising from 10% to 90% by weight
of said active ketone or aldehyde containing component and having a viscosity greater than
lOOOcps.
b) mixing therewith, at a temperature just above the carrier melting point, a
carrier having a melting point of between 30°C and 135°C in the ratio of 3-95% to produce
particles of processed amine reaction product containing from 1% to 75% by weight of said
amine reaction product, and
c) optionally treating the particle by conventional manner to form a coated
particle.

2. A process as claimed in any of the preceding claims, wherein the amine reaction
product comprises from 30% to 85% of said active ketone or aldehyde containing
component.

4. A process as claimed in any of the preceding claims, wherein the active component is
selected from a flavour ketone or aldehyde ingredient, a pharmaceutical ketone or aldehyde
active, a biocontrol ketone or aldehyde agent, a perfume ketone or aldehyde component, a
refreshing cooling ketone or aldehyde agent and/or mixtures thereof.
5. 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
