Abstract:
1. A coated microparticulate composition comprising a microparticulate having a particle size in the range of about 1 μm to about 500 μm, a Type-1 Polymer, and a Type-2 Polymer; wherein the microparticulate comprises a benefit agent comprising about 35 wt. % to about 99.5 wt. % of the coated microparticulate; and wherein the microparticulate is coated: first with the Type-1 Polymer, wherein the Type-1 Polymer comprises a cationic polymer with a cationic atom content of about 3 wt. % to about 20 wt. % and a weight average molecular weight of about 300,000 to about 800,000 Dalton; and then with the Type-2 Polymer, wherein the Type-2 Polymer comprises a cationic polymer with a cationic atom content of about 0.1 wt. % to about 3 wt. % and a weight average molecular weight greater than about 1,000,000 Dalton; wherein the weight ratio of the Type-1 Polymer to Type-2 Polymer is in the range of 3 to 7.
