A solid dissolvable composition comprising:
- crystallizing agent;
- water;
- and a population of capsules comprising freshness benefit agent;
- wherein the crystallizing agent is the sodium salt of saturated fatty acids having from 8 to about 12 methylene groups;
- and
- wherein the capsules comprise:
- a core comprising an oil-based freshness benefit agent;
- and
- a shell surrounding the core, the shell comprising:
- a substantially inorganic first shell component comprising:
- a condensed layer comprising a condensation product of a precursor, and
- a nanoparticle layer comprising inorganic nanoparticles, wherein the condensed layer is disposed between the core and the nanoparticle layer, and
- an inorganic second shell component surrounding the first shell component, wherein the second shell component surrounds the nanoparticle layer, and
- wherein the precursor comprises at least one compound of Formula (I):
- (MvOzYn)w (Formula I)
- where M is one or more of silicon, titanium and aluminum,
- v is the valence number of M and is 3 or 4,
- z is from 0.5 to 1.6
- each Y is independently selected from —OH, —OR2, halo,
- —NH2, —NHR2, —N(R2)2, and
- wherein R2 is a C1 to C20 alkyl, C1 to C20 alkylene, C6 to C22 aryl, or a 5-12 membered heteroaryl comprising from 1 to 3 ring heteroatoms selected from O, N, and S,
- R3 is a H, C1 to C20 alkyl, C1 to C20 alkylene, C6 to C22 aryl, or a 5-12 membered heteroaryl comprising from 1 to 3 ring heteroatoms selected from O, N, and S,
- n is from 0.7 to (v-1), and
- w is from 2 to 2000.
