1. Basic Information
Name: Chlorhexidine Digluconate
Alias: 1,1'-Hexamethylenebis[5-(4-chlorophenyl)biguanide] digluconate
CAS No.: 18472-51-0
Molecular Formula: C22H30Cl2N10·2C6H12O7
Molecular Weight: 897.76
2. Physical and Chemical Properties
Physical Properties
- Appearance: Colorless to pale yellow transparent viscous liquid (commonly supplied as 20% aqueous solution)
- Odor: Slight characteristic odor
- Solubility: Miscible freely with water, ethanol, propylene glycol; insoluble in non-polar solvents such as mineral oil, chloroform
- Aqueous solution pH: 5.5–7.0
- Hygroscopicity: Liquid product has high water miscibility, no obvious hygroscopicity
- Surface activity: Cationic surfactant, adsorbs to bacterial cell membrane surface
Chemical Properties
- Molecular structure: Cationic biguanide compound complexed with two gluconate anions
- Broad-spectrum bactericidal mechanism: Positively charged molecules combine with negatively charged bacterial proteins, denature cytoplasm and kill bacteria, fungi and partial viruses
- Ion incompatibility: Precipitates immediately when mixed with anionic surfactants, soap, phosphate and carbonate
- Thermal stability: Stable under normal temperature; long-term boiling will reduce effective bactericidal content
- Photostability: Stable under indoor light; avoid long-term strong ultraviolet irradiation
- Compatibility: Compatible with nonionic surfactants, neutral thickeners; incompatible with anionic raw materials, heavy metal salts, iodine preparations
