Claim 19:
20. A process of making a liquid fabric care composition comprising:
providing a liquid base composition comprising a member selected from the group consisting of a fabric treatment adjunct, water, and mixtures thereof,
wherein the fabric treatment adjunct is selected from the group consisting of a conditioning active, a surfactant, or a mixture thereof,
wherein, if present, the conditioning active is selected from the group consisting of an alkyl quaternary ammonium compound (“alkyl quat”), an alkyl ester quaternary ammonium compound (“alkyl ester quat”), and mixtures thereof, and
wherein, if present, the surfactant is selected from the group consisting of anionic surfactant, nonionic surfactant, cationic surfactant, zwitterionic surfactant, amphoteric surfactant, ampholytic surfactant, and mixtures thereof; and

providing a population of capsules to the base composition,
the capsules comprising a core and a shell surrounding the core,
wherein the core comprises perfume raw materials,
wherein the shell comprises:
a substantially inorganic first shell component comprising a condensed layer and a nanoparticle layer,
wherein the condensed layer comprises a condensation product of a precursor,
wherein the nanoparticle layer comprises inorganic nanoparticles, and
wherein the condensed layer is disposed between the core and the nanoparticle layer;

an inorganic second shell component surrounding the first shell component, wherein the second shell component surrounds the nanoparticle layer;

wherein the precursor comprises at least one compound from the group consisting of Formula (I), Formula (II), and a mixture thereof,
wherein Formula (I) is (MVOzYn)w,
wherein Formula (II) is (MVOzYnR1p)w,

wherein for Formula (I), Formula (II), or the mixture thereof:
each M is independently selected from the group consisting 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, halogen,, 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, wherein the heteroaryl comprises from 1 to 3 ring heteroatoms selected from O, N, and S,
wherein R3 is a H, C1 to C20 alkyl, C1 to C20 alkylene, C6 to C22 aryl, or a 5-12 membered heteroaryl, wherein the heteroaryl comprises from 1 to 3 ring heteroatoms selected from O, N, and S,

w is from 2 to 2000;
wherein for Formula (I),
n is from 0.7 to (v-1); and

wherein for Formula (II),
n is from 0 to (v-1);
each R1 is independently selected from the group consisting of: a C1 to C30 alkyl; a C1 to C30 alkylene; a C1 to C30 alkyl substituted with a member selected from the group consisting of a halogen, —OCF3, —NO2, —CN, —NC, —OH, —OCN, —NCO, alkoxy, epoxy, amino, mercapto, acryloyl, —C(O)OH, —C(O)O-alkyl, —C(O)O-aryl, and —C(O)O-heteroaryl; and a C1 to C30 alkylene substituted with a member selected from the group consisting of a halogen, —OCF3, —NO2, —CN, —NC, —OH, —OCN, —NCO, alkoxy, epoxy, amino, mercapto, acryloyl, —C(O)OH, —C(O)O-alkyl, —C(O)O-aryl, and —C(O)O-heteroaryl; and
p is a number that is greater than zero and is up to pmax,
 wherein pmax=60/[9*Mw(R1)+8],, wherein Mw(R1) is the molecular weight of the R1 group.
