THOR Specialties srl - BIOCIDES

Thor’s biocides provide safe and effective protection against the microbiological spoilage of a wide variety of products.


Our main expertise lies in the production and formulation of standard and customized biocides based on own manufactured actives including isothiazolinones (available from two major Thor sites), formaldehyde donors and IPBC. A range of quaternary ammonium compounds is also amongst Thor manufactured biocides marketed under the international trademark ACTICIDE®. These biocides prevent the biodeterioration of products both in their wet/fluid, dry/cured and intermediate states.


Thor has pioneered the development of protection technology for biocides for dry film applications. The result of many years of progress has resulted in Thor AMME (Advanced Micro Matrix Embedding). This novel technology has enabled the creation of a new generation of dry film biocides with a wide range of benefits.

High Purity Isothiazolinones

Our high purity isothiazolinones with innovative stabilizing systems have gained ready acceptance by users and regulatory bodies such as the US EPA and FDA. In addition we will be supporting all our major actives through the European BPR and other regulatory bodies.
