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.
Claims31
A coated triggered start product comprising:
- 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 causing 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 after the product is exposed to moisture.
A process for producing a triggered start product comprising
- providing particulate core material comprising at least one water soluble composition;
- and
- applying a coating layer on the core material;
- the coating layer being formulated to cause the product to exhibit “lock-off” type release characteristics whereby release of the core material from the coated product is essentially completely suppressed until release is initiated by application of a trigger material to the additional coating layer after the product is exposed to moisture.
A process for use of a triggered start product in a substrate comprising:
- (a) providing a triggered start product comprising:
- (i) a particulate core material comprising at least one water soluble active constituent, and
- (ii) at least one coating layer applied on the particulate core material;
- the coating layer causing 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;
- (b) mixing the triggered start product in a substrate;
- (c) dissolving the trigger material in water;
- and
- (d) applying the dissolved trigger material onto the substrate containing the triggered release product by watering or spraying.
