Liquid fabric care compositions comprising capsules

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;
• a population of capsules,
• the capsules comprising a core and a shell surrounding the core,
• wherein the core comprises perfume raw materials,
• wherein the core is liquid;
• wherein the shell is substantially inorganic and comprises silica and no more than 10% organic content;
• wherein the shell comprises a mean shell thickness of 5 nm to 500 nm;
• wherein the capsules comprise a mean volume weighted capsule diameter between 1 μm and 100 μm;
• wherein the population of capsules has a permeability between 0.01% and 40%;
• and
• wherein the population of capsules has a fracture strength between 0.5M Pa and 10 MPa;
• and
• a free perfume, wherein the free perfume is present at a level of from 0.1% to 10%, by weight of the liquid fabric care composition.
