ABSTRACT:
Powdered, abrasive, hard surface cleansers containing micro-encapsulated perfume wherein the capsules are essentially water-insoluble, but can become perfume permeable during use by the combined action of water and abrasive. The preferred capsules are formed from gelatin and a polyanionic material by coacervation techniques and then are cross-linked to provide controlled water insolubility.
