Claim 0:
1. An antiperspirant or deodorant composition comprising
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 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, —CO2H, —C(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 p max=60/[9*Mw(R1)+8],

 wherein Mw(R1) is the molecular weight of the R1 group.
