Denatonium saccharinate

Denatonium saccharinate (CAS 90823-38-4) is an intensely bitter salt formed from denatonium and saccharin, sold under trade names including Ro-Pel, Amerex, and Super Vilex. It carries no E-code designation and is recognized as one of the most bitter substances known, active at concentrations in the parts-per-billion range.

In agriculture and consumer products, denatonium saccharinate functions as an aversive agent, deterring ingestion or contact by triggering an immediate bitter taste response. It is incorporated into pesticide formulations, animal repellent sprays, and personal care products such as nail-biting deterrents, where concentrations typically range from 10 to 100 ppm.

The material is supplied as a solid and is subject to REACH registration requirements within the EU. Procurement should confirm supplier compliance with relevant quality standards and request a full safety data sheet. Packaging formats vary by supplier; enquire for available quantities and documentation.
