Octenidine HCl, also known as Octenidine Hydrochloride or Octenidine Dihydrochloride, is a cationic antimicrobial specialty ingredient used in selected cosmetic and personal-care formulations. It is the hydrochloride salt of Octenidine and is valued primarily for its antimicrobial functionality.
Octenidine HCl has the molecular formula C₃₆H₆₄Cl₂N₄ and a molecular weight of approximately 623.84 g/mol. It is generally supplied as a white to almost-white crystalline powder. Its cationic structure and antimicrobial properties make it relevant to formulation systems where microbiological control is an important consideration.
The ingredient is particularly relevant to specialty personal-care formulations and antimicrobial cosmetic systems. The exact application, concentration and regulatory status should always be evaluated for the intended finished product and target market.
Octenidine HCl is identified by CAS Number 70775-75-6 and EC Number 274-861-8. The parent compound Octenidine is identified by CAS 71251-02-0, while the hydrochloride salt is the dihydrochloride form.
Its chemical name is N,N′-(1,10-decanediyldi-1(4H)-pyridinyl-4-ylidene)bis-1-octanamine dihydrochloride. Other names include Octenidine Dihydrochloride, Octenidine Hydrochloride, Octenidine HCl and WIN 41,464-2.
Octenidine HCl has a molecular formula of C₃₆H₆₄Cl₂N₄ and molecular weight of approximately 623.84 g/mol. It is a solid at normal room temperature. A current commercial analytical specification reports a white to almost-white powder or crystalline material, with minimum 98.0 area% HPLC purity and a melting range of approximately 212–216°C.
Octenidine HCl is primarily associated with antimicrobial functionality. Cosmetic ingredient references identify OCTENIDINE HCL as an antimicrobial ingredient, reflecting its ability to interact with microbial cell membranes through its cationic chemical structure.
Its antimicrobial characteristics make Octenidine HCl relevant to specialty cosmetic and personal-care formulations where maintaining microbiological quality or providing antimicrobial functionality is part of the formulation objective.
The antimicrobial activity of a raw material should not automatically be interpreted as a universal preservation claim. Finished cosmetic formulations require appropriate preservation strategy, compatibility assessment, stability evaluation and regulatory review according to the target market.
Octenidine HCl Cosmetic Ingredient can be considered for specialty skin-care, cleansing, personal-care and antimicrobial formulation systems where a cationic antimicrobial ingredient is appropriate.
Its use can be evaluated in aqueous or water-containing formulation systems according to the physical and chemical requirements of the selected grade. The ingredient may also be incorporated into specialized cosmetic preparations designed around antimicrobial functionality.
Because Octenidine HCl is a strongly functional specialty ingredient, formulators should evaluate its compatibility with anionic surfactants, polymers, emulsifiers and other charged ingredients. Cationic-active materials can interact with oppositely charged components, potentially affecting formulation performance.
The final concentration should be established according to the specific formulation, validated product performance and applicable regulations rather than applying an arbitrary generic concentration.
Octenidine HCl should be handled according to the technical specification of the supplied grade. Relevant quality parameters can include identity, HPLC purity, water content, residue on ignition, heavy metals, pH, related substances and physical characteristics.
A current TCI specification reports minimum 98.0 area% HPLC purity and a melting point of 212–216°C for its Octenidine Dihydrochloride analytical grade. This is a supplier-specific analytical specification, not a universal cosmetic raw-material standard.
Another current analytical supplier specification reports purity ≥97.5%, demonstrating that commercial specifications can differ by grade and analytical method.
For this reason, the actual SDP COA should define the applicable assay method and acceptance limits. Where the commercial material is tested by validated HPLC, the HPLC purity can be reported accordingly. Where another validated method is used, the CMS field should reflect that method rather than assuming HPLC.
Octenidine HCl is a specialty antimicrobial ingredient for selected cosmetic and personal-care formulation requirements. A reliable Octenidine HCl Cosmetic Ingredient Manufacturer in India can provide material with defined chemical identity, purity and technical characteristics according to the selected grade.
As an Octenidine HCl manufacturer and supplier in India, Swapnroop can support bulk requirements for specialty cosmetic raw materials and personal-care ingredients. Product specifications can be established according to the intended application, analytical requirements and customer quality standards.
For commercial formulation development, consistent control of HPLC purity, identity, physical appearance, melting range and relevant impurities is important for maintaining reproducible raw-material quality.
