The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, compositions for cleaning, fabric care, or coating onto various substrates, textiles or surfaces, such particles increase the efficiency of benefit agent delivery, thereby allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.
A composition comprising a particle composition comprising one or more particles comprising a core material and a wall material that at least partially surrounds said core material, said particles being selected from the group consisting of Type 1 particles having a Volume Weighted Fracture Strength of less than about 0.8 MPa, Type 2 particles having a Volume Weighted Fracture Strength of from about 0.5 0.8 MPa to about less than 2 MPa, Type 3 particles having a Volume Weighted Fracture Strength of from about 1.5 2 MPa to about less than 5 MPa, Type 4 particles having a Volume Weighted Fracture Strength of from about 5 MPa to about 16 MPa, and mixtures thereof, wherein the volume weight of each type of particle in said particle composition is as follows:
