Overview
Octenidine dihydrochloride (CAS 70775-75-6 ), also marketed as Octenidine HCl, is a broad-spectrum antimicrobial active used in pharmaceutical and personal care formulations. It delivers effective bactericidal and fungicidal action at low concentrations.
This makes it a preferred preservative and antiseptic ingredient for topical and mucosal applications. In pharmaceutical wound care, it is the active ingredient in antiseptic wound gels, rinses, and impregnated dressings.
These applications are ideal where alcohol-free, tissue-compatible disinfection is required. Oral care products such as antiseptic mouthwashes and throat sprays rely on it for plaque-reducing and antimicrobial efficacy.
In personal care, it functions as a preservative and antimicrobial booster in leave-on and rinse-off formulations. This includes intimate hygiene products and skin cleansers where gentle yet effective action is needed.
It is also used in catheter care solutions and surgical site preparation products within hospital-grade antiseptic lines. The material is supplied as a white to off-white crystalline powder for industrial use.
It is available in pharmaceutical-grade specifications suited for topical and mucosal drug product manufacturing. Bulk quantities are typically offered for direct formulation use with full documentation packages.
These packages support procurement processes that must remain GMP -compliant. The high purity of the compound ensures stability and performance across a wide range of medical and cosmetic applications.
