  • Patent number: 4540721
    Abstract: A method is presented for using scented oils to provide odor to a container of a product having a constituent incompatible with the scented oils. An aqueous emulsion which comprises from about 4% to about 70% of a water-emulsifiable or water-soluble polymer, from about 5% to about 80% of scented oils, and from about 6% to about 80% of water is prepared. The aqueous emulsion is dried whereby the scented oils are entrapped within the matrix of the polymer. The polymer matrix is included in the container with the product whereby the scented oils are protected by the polymer matrix from degradation by the incompatible constituent and diffuse from the polymer matrix over a period of time.

  • Patent number: 4534879
    Abstract: A process for making improved synthetic surfactant flakes from a water-wet paste which is dried on a heated roll drum dryer. Hot surfactant flakes are made from drum drying a water-wet paste containing sodium alkyl sulfate (AS), sodium alkyl benzene sulfonate (LAS), and water-soluble inorganic salts, preferably sodium chloride and magnesium chloride blends. The hot flakes are cooled in a low moisture environment having a dewpoint of up to 10.degree. C., e.g., under a dry nitrogen or dry air blanket. The low moisture environment prevents undesirable, insidious hydration and stabilizes the AS/LAS flakes. The stable AS/LAS surfactant flakes can be used to make more economical, more processable, firmer improved surfactant cakes. One advantage is that cakes made with the flakes of this invention can contain larger amounts of perfume than cakes made with comparable AS/LAS flakes cooled above said dewpoint.
