  • Patent number: 5891833
    Abstract: A process for preparing liquid personal cleansing compositions which provides enhanced perfume deposition on the skin and which provides increased on-skin fragrance longevity. The liquid personal cleansing compositions contain from about 0.01% to about 5% of a cationic polymer; from about 1% to about 80% of an anionic surfactant; from about 0.01% to about 5% of a volatile perfume; and water. The ratio of the cationic polymer to the anionic surfactant ranges from about 1:100 to about 1:2. The process involves first forming a premix comprising the cationic polymer, the volatile perfume and water, and then adding the premix to a personal cleansing base composition which comprises anionic surfactant and water.
