ABSTRACT:
A composition comprising hydrotalcite-like compound intercalated with an organic anion such as organic sulfonic anions, sulfuric acid ester anions, phosphoric acid ester anions, carboxylic anions and N-acylamino acid anions and various active agents such as pesticidal active agents, for example an insecticide, a fungicide, a repellent, etc. and a perfume supported by said hydrotalcite-like compound, can release an active agent gradually over a long time while retaining the active agent stably for a long time, so that it has a long acting effect and can be used for various applications such as a pesticidal formulation.
