Description
Chlorhexidine diacetate (CAS 56-95-1) is a broad-spectrum antimicrobial salt derived from chlorhexidine, also known commercially as Hibitane diacetate and Arlacide A. It carries no assigned E-code and is classified under HS code 2925294500 within the pharmaceutical intermediates category.
In pharmaceutical and personal care formulations, chlorhexidine diacetate disrupts bacterial cell membranes by binding to negatively charged phospholipids, making it effective as a preservative in wound care products, surgical scrubs, and antiseptic rinses. In water treatment, it functions as a biocide at controlled concentrations to inhibit microbial growth in process water systems.
The material is supplied as a microcrystalline powder conforming to Ph.Eur. monograph specifications, with REACH compliance documentation available. Procurement teams can request certificates of analysis aligned to pharmaceutical-grade standards. Packaging formats are available to suit both laboratory-scale and bulk industrial requirements.
