Active Substances

Active Substances

An active substance is an ingredient that has an effect on a target organism. Sumitomo Chemical’s active substances are effective against insects and parasites that are harmful to human and animal health, including mosquitoes, ticks, fleas, mites, cockroaches and houseflies.

Many of our active substances are pyrethroid insecticides, which are organic compounds similar in structure to pyrethrins, a class of chemicals found in certain chrysanthemum flowers and used in Asia as early as 1800 to control ticks, fleas and mosquitoes.

Pyrethroids have become an important family of active substances for use in household insecticides. Some of the active substances developed by Sumitomo Chemical are among the fastest-acting insecticides available, and many demonstrate long-lasting bite inhibition and repellent effects.
