Abstract

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, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by 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.

  • FIELD OF INVENTION
  • [0002]
    The present application relates to benefit agent containing delivery particles, compositions comprising such particles, and processes for making and using such particles and compositions.
  • BACKGROUND OF THE INVENTION
  • [0003]
    Benefit agents, such as perfumes, silicones, waxes, flavors, vitamins and fabric softening agents, are expensive and/or generally less effective when employed at high levels in consumer products, for example, personal care compositions, cleaning compositions, and fabric care compositions. As a result, there is a desire to maximize the effectiveness of such benefit agents. One method of achieving such objective is to improve the delivery efficiencies of such benefit agents. Unfortunately, it is difficult to improve the delivery efficiencies of benefit agents as such agents may be lost do to the agents' physical or chemical characteristics, or such agents may be incompatible with other compositional components or the situs that is treated.
  • [0004]
    Accordingly, there is a need for a benefit agent containing delivery particle that provides improved benefit agent delivery efficiency.
  • SUMMARY OF THE INVENTION
  • [0005]
    The present invention relates to benefit agent containing delivery particles comprising a core material and a wall material that at least partially surrounds the core material. The present invention also relates to compositions comprising said particles, and processes for making and using such particles and compositions.

  • [0261]
    1200 g of perfume microcapsule slurry, containing one or more of the variants of microcapsules disclosed in the present specification, is mixed together with 700 g of water for 10 minutes using an IKA Eurostar mixer with R1382 attachment at a speed of 180 rpm. The mixture is then transferred over to a feeding vessel to be spray dried in a 1.2 m diameter Niro Production Minor. The slurry is fed into the tower using a Watson-Marlow 504U peristaltic pump and atomised using a 100 mm diameter rotary atomiser run at 18000 rpm, with co-current air flow for drying. The slurry is dried using an inlet temperature of 200° C. and outlet temperature of 95° C. to form a fine powder. The equipment used the spray drying process may be obtained from the following suppliers: IKA Werke GmbH & Co. KG, Janke and Kunkel—Str. 10, D79219 Staufen, Germany; Niro A/S Gladsaxevej 305, P.O.
