Abstract
A low-water composition comprising a solid dissolvable composition domain having a crystallizing agent and a PEGC domain.
Claims19
A low-water composition, comprising:
- 1) At least one solid dissolvable composition domain (SDC) having crystallizing agent;
- 2) at least one polyethylene glycol domain (PEGC);
- 3) a population of capsules comprising freshness benefit agent;
- and
- wherein the crystallizing agent is the sodium salt of saturated fatty acids having from 8 to about 12 carbon atoms;
- wherein the capsules are present in at least one of the SDC or PEGC;
- wherein the low-water composition has a water content of less than about 10 wt. %;
- and
- wherein the sodium salt of saturated fatty acids of the crystallizing agent comprises from 50 wt. % to 70 wt. % C12, 15 wt. % to 25 wt. % C10, and 15 wt. % to 25 wt. % C8;
- and
- wherein the capsules comprise:
- an oil-based core comprising a 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.
