Diclosan

Diclosan (CAS 3380-30-1) is a chlorinated diphenyl ether compound with established antimicrobial activity, commercially available under trade names including Tinosan HP 100 and Soneclosan. It carries no assigned E-code and is classified within heterocyclic compounds for regulatory and trade purposes.

In personal care and textile applications, Diclosan functions by disrupting microbial cell membrane integrity, inhibiting bacterial and fungal growth at low concentrations. Water treatment formulators use it as a preservative biocide to control microbial contamination in process water systems, while pharmaceutical manufacturers incorporate it into topical preparations requiring broad-spectrum antimicrobial protection.

Diclosan is supplied as a solid and is subject to REACH registration requirements within the European Union, with procurement teams advised to request a current Safety Data Sheet and confirm compliance documentation prior to ordering. Packaging formats and available grades should be confirmed directly with the supplier based on application requirements.
