Claim 13:
14. A method of making a composition comprising a plurality of particles according to claim 1, wherein said method comprises the steps of:
1) providing a slurry comprising:
(a) from 20% to 90% of molten polyalkylene glycol by total weight of said slurry,
(b) from 10% to 80% of said perfume by total weight of said slurry;

2) atomizing said slurry through an atomizer into a chamber maintained at a temperature below the melting point of said polyalkylene glycol resulting in the formation of microparticles containing said polyalkylene glycol and said perfume;
3) mixing said microparticles with a powder comprising said effervescent system and said co-carrier to form a mixed powder in which the weight ratio of said microparticles to said powder is from 5:1 to 1:5; and
4) compressing said mixed powder into particles.
