  • Controlled release products and processes for the preparation thereof
    Patent number: 6987082
    Abstract: A controlled release product is provided having a suppressed initial release period and a predetermined longevity. The product includes a particulate water soluble core material and a semi-permeable coating layer applied on the core material for controlling the release rate of the core material.
    Type: Grant
    Filed: October 10, 2003
    Date of Patent: January 17, 2006
    Assignee: OMS Investments, Inc.

  • Triggered start products and processes for the production and use thereof
    Patent number: 6787234
    Abstract: A coated triggered start product is formed from a particulate core material comprising at least one water soluble active constituent and at least one coating layer applied on the particulate core material. The coating layer causes the product to exhibit “lock-off” type release characteristics whereby release of the active constituent of the core material from the coated product is essentially completely suppressed until release is initiated by application of a trigger material to the coating layer. Processes for preparing and using such triggered start products are also provided.
