1. A liquid fabric care composition comprising:
a fabric treatment adjunct,
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
a population of capsules,
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 selected 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,
